Microsoft today released software updates to plug 100 security holes in its Windows operating systems and other software, including a zero-day vulnerability that is already being used in active attacks. Not to be outdone, Apple has released a set of important updates addressing two zero-day vulnerabilities that are being used to attack iPhones, iPads and Macs.
On April 7, Apple issued emergency security updates to fix two weaknesses that are being actively exploited, including CVE-2023-28206, which can be exploited by apps to seize control over a device. CVE-2023-28205 can be used by a malicious or hacked website to install code.
Both vulnerabilities are addressed in iOS/iPadOS 16.4.1, iOS 15.7.5, and macOS 12.6.5 and 11.7.6. If you use Apple devices and you don’t have automatic updates enabled (they are on by default), you should probably take care of that soon as detailed instructions on how to attack CVE-2023-28206 are now public.
Microsoft’s bevy of 100 security updates released today include CVE-2023-28252, which is a weakness in Windows that Redmond says is under active attack. The vulnerability is in the Windows Common Log System File System (CLFS) driver, a core Windows component that was the source of attacks targeting a different zero-day vulnerability in February 2023.
“If it seems familiar, that’s because there was a similar 0-day patched in the same component just two months ago,” said Dustin Childs at the Trend Micro Zero Day Initiative. “To me, that implies the original fix was insufficient and attackers have found a method to bypass that fix. As in February, there is no information about how widespread these attacks may be. This type of exploit is typically paired with a code execution bug to spread malware or ransomware.”
According to the security firm Qualys, this vulnerability has been leveraged by cyber criminals to deploy Nokoyawa ransomware.
“This is a relatively new strain for which there is some open source intel to suggest that it is possibly related to Hive ransomware – one of the most notable ransomware families of 2021 and linked to breaches of over 300+ organizations in a matter of just a few months,” said Bharat Jogi, director of vulnerability and threat research at Qualys.
Jogi said while it is still unclear which exact threat actor is targeting CVE-2023-28252, targets have been observed in South and North America, regions across Asia and at organizations in the Middle East.
Satnam Narang at Tenable notes that CVE-2023-28252 is also the second CLFS zero-day disclosed to Microsoft by researchers from Mandiant and DBAPPSecurity (CVE-2022-37969), though it is unclear if both of these discoveries are related to the same attacker.
Seven of the 100 vulnerabilities Microsoft fixed today are rated “Critical,” meaning they can be used to install malicious code with no help from the user. Ninety of the flaws earned Redmond’s slightly less-dire “Important” label, which refers to weaknesses that can be used to undermine the security of the system but which may require some amount of user interaction.
Narang said Microsoft has rated nearly 90% of this month’s vulnerabilities as “Exploitation Less Likely,” while just 9.3% of flaws were rated as “Exploitation More Likely.” Kevin Breen at Immersive Labs zeroed in on several notable flaws in that 9.3%, including CVE-2023-28231, a remote code execution vulnerability in a core Windows network process (DHCP) with a CVSS score of 8.8.
“‘Exploitation more likely’ means it’s not being actively exploited but adversaries may look to try and weaponize this one,” Breen said. “Micorosft does note that successful exploitation requires an attacker to have already gained initial access to the network. This could be via social engineering, spear phishing attacks, or exploitation of other services.”
Breen also called attention to CVE-2023-28220 and CVE-2023-28219 — a pair of remote code execution vulnerabilities affecting Windows Remote Access Servers (RAS) that also earned Microsoft’s “exploitation more likely” label.
“An attacker can exploit this vulnerability by sending a specially crafted connection request to a RAS server, which could lead to remote code execution,” Breen said. While not standard in all organizations, RAS servers typically have direct access from the Internet where most users and services are connected. This makes it extremely enticing for attackers as they don’t need to socially engineer their way into an organization. They can simply scan the internet for RAS servers and automate the exploitation of vulnerable devices.”

Microsoft is sending the world a whole bunch of love today, in the form of patches to plug dozens of security holes in its Windows operating systems and other software. This year’s special Valentine’s Day Patch Tuesday includes fixes for a whopping three different “zero-day” vulnerabilities that are already being used in active attacks.
Microsoft’s security advisories are somewhat sparse with details about the zero-day bugs. Redmond flags CVE-2023-23376 as an “Important” elevation of privilege vulnerability in the Windows Common Log File System Driver, which is present in Windows 10 and 11 systems, as well as many server versions of Windows.
“Sadly, there’s just a little solid information about this privilege escalation,” said Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative. “Microsoft does note that the vulnerability would allow an attacker to exploit code as SYSTEM, which would allow them to completely take over a target. This is likely being chained with a remote code execution bug to spread malware or ransomware. Considering this was discovered by Microsoft’s Threat Intelligence Center, it could mean it was used by advanced threat actors. Either way, make sure you test and roll these fixes quickly.”
The zero-day CVE-2023-21715 is a weakness in Microsoft Office that Redmond describes as a “security feature bypass vulnerability.”
“Microsoft lists this as under active exploit, but they offer no info on how widespread these exploits may be,” Childs said. “Based on the write-up, it sounds more like a privilege escalation than a security feature bypass, but regardless, active attacks in a common enterprise application shouldn’t be ignored. It’s always alarming when a security feature is not just bypassed but exploited. Let’s hope the fix comprehensively addresses the problem.”
The third zero-day flaw already seeing exploitation is CVE-2023-21823, which is another elevation of privilege weakness — this one in the Microsoft Windows Graphic component. Researchers at cybersecurity forensics firm Mandiant were credited with reporting the bug.
Kevin Breen, director of cyber threat research at Immersive Labs, pointed out that the security bulletin for CVE-2023-21823 specifically calls out OneNote as being a vulnerable component for the vulnerability.
“In recent weeks, we have seen an increase in the use of OneNote files as part of targeted malware campaigns,” Breen said. “Patches for this are delivered via the app stores and not through the typical formats, so it’s important to double check your organization’s policies.”
Microsoft fixed another Office vulnerability in CVE-2023-21716, which is a Microsoft Word bug that can lead to remote code execution — even if a booby-trapped Word document is merely viewed in the preview pane of Microsoft Outlook. This security hole has a CVSS (severity) score of 9.8 out of a possible 10.
Microsoft also has more valentines for organizations that rely on Microsoft Exchange Server to handle email. Redmond patched three Exchange Server flaws (CVE-2023-21706, CVE-2023-21707, and CVE-2023-21529), all of which Microsoft says are remote code execution flaws that are likely to be exploited.
Microsoft said authentication is required to exploit these bugs, but then again threat groups that attack Exchange vulnerabilities also tend to phish targets for their Exchange credentials.
Microsoft isn’t alone in dropping fixes for scary, ill-described zero-day flaws. Apple on Feb. 13 released an update for iOS that resolves a zero-day vulnerability in Webkit, Apple’s open source browser engine. Johannes Ullrich at the SANS Internet Storm Center notes that in addition to the WebKit problem, Apple fixed a privilege escalation issue. Both flaws are fixed in iOS 16.3.1.
“This privilege escalation issue could be used to escape the browser sandbox and gain full system access after executing code via the WebKit vulnerability,” Ullrich warned.
On a lighter note (hopefully), Microsoft drove the final nail in the coffin for Internet Explorer 11 (IE11). According to Redmond, the out-of-support IE11 desktop application was permanently disabled on certain versions of Windows 10 on February 14, 2023 through a Microsoft Edge update.
“All remaining consumer and commercial devices that were not already redirected from IE11 to Microsoft Edge were redirected with the Microsoft Edge update. Users will be unable to reverse the change,” Microsoft explained. “Additionally, redirection from IE11 to Microsoft Edge will be included as part of all future Microsoft Edge updates. IE11 visual references, such as the IE11 icons on the Start Menu and taskbar, will be removed by the June 2023 Windows security update (“B” release) scheduled for June 13, 2023.”
For a more granular rundown on the updates released today, see the SANS Internet Storm Center roundup. If today’s updates cause any stability or usability issues in Windows, AskWoody.com will likely have the lowdown on that.

Cybersecurity attacks complication and damaging impact are always keeping SOC analyst at their edge. Extended Detection and Response (XDR) solutions tend to simplify for Sam, a SOC analyst, his job by simplifying the workflow and process that involve the lifecycle of a threat investigation from detection to response. In this post we will explore how SecureX, Secure Cloud Analytics (NDR), Secure Endpoint (EDR) with their seamless integration accelerate the ability to achieve XDR outcomes.
One of the first challenges for Sam is alert fatigue. With the overwhelming number of alerts coming from multiple sources and the lack of relevance or correlation, decreases the value of these alerts to the point that they become as meaningless as having none. To counter this effect, Cisco Secure Cloud Analytics and Cisco Secure Endpoint limit alert promotion to SecureX to only include high fidelity alerts with critical severity and marking them as High Impact incidents within SecureX Incident manager.
This capability reduces the noise coming from the source, while keeping the other alerts available for investigation, putting impactful incidents at the top of Sam’s to do list. Now, Sam is confident that his time is spent in a prioritized manner and helps ensure he is tackling the most important threats first. Automatic incident provisioning accelerates incident response by bringing focus on the most impactful incidents.
Understanding the mechanics and data around a specific incident is a key factor for Remi, an incident responder, in his day-to-day work. Achieving his tasks accurately is tightly coupled with his ability to scope and understand the impact of an incident and to gather all possible data from the environment which can be associated with an incident including devices, users, files hashes, email ids, domains IPs and others. SecureX Incident Manager’s automatic enrichment capability completes this data collection for high impact incidents automatically. The data is then classified into targets, observables, and indicators and added to the incident to help the analyst better understand the incident’s scope and potential impact.
The Incident Manager and automatic enrichment provides Remi with crucial information such as the associated MITRE Tactics and Techniques applied during this incident, the contributing threat vectors, and security solutions. In addition, the Incident Manager aggregates events from multiple sources into the same high impact incident that the enrichment was triggered on future providing Remi with more vital context.
This automatic enrichment for high impact incidents is essential to Remi’s understanding as much as possible about an incident as it occurs and significantly accelerates him identifying the proper response for the threat. This brings us to the next step in our incident detection to response workflow.
It is important for an XDR to correlate the right information for the Security Analyst and incident responder to understand an attack but it is equally important to provide an effective response mechanism. This is exactly what SecureX provides with the ability to apply a response to an observable with a simple a single click or through automation.
These workflows can be invoked to block a domain, IP or URL across a full environment with a simple click, leveraging existing integrations such as firewalls or umbrella and others. Workflows can be made available to the threat response pivot menu where they are useful for performing specific host specific actions, such as isolate a host, take a host snapshot, and more.
In addition to response workflows, the pivot menu provides the ability to leverage Secure Cloud Analytics (SCA) telemetry by generating a case book linking back to telemetry searches within SCA. This automation is critical to understanding the spread of a threat across an environment. A good example on this, is identifying all hosts communicating to a command-and-control destination before this destination was identified as malicious. This is a pre-existing SecureX workflow which can be taken advantage of today see workflow 0005 – SCA – Generate Case book with Flow Links.
Reducing time to remediation is a key aspect of keeping a business secure, SecureX orchestration automates responses with various solutions specially with NDR detections from SCA and use observables from these alerts to isolate hosts leveraging Secure Endpoint. SCA can send alerts via Webhooks and SecureX Orchestration receive them as triggers to launch an NDR- EDR workflow to isolate hosts automatically. (0014-SCA-Isolate endpoints from alerts)
This orchestration workflow automatically isolates rogue devices in a network or contain confirmed threat alerts received from Cisco’s Machine learning threat detection cloud and can be used for multiple different response scenarios.
The power of automation brought by SecureX, Secure Cloud Analytics and Secure Endpoint accelerates XDR outcomes drastically which simplifies Security Analyst (Sam) and Incident Responder (Remi) jobs and make it more efficient with accurate incident prioritization, automatic investigation/enrichment and most importantly automating responses.

We recently had the chance to discuss the top trend predictions for 2023, issued by Gartner®, and what these may mean for CISOs. The trends are below:
These showed several themes: internal pressures, external changes and solution adoption.
CISOs need to be aware of the pressures that may come from inside the business. C Level executives having risk related elements in their employment contracts (8) may result in a higher focus on Risk management. This may benefit CISOs to position cyber security as part of the Risk calculation and perhaps unlock more support for risk reduction initiatives.
Aligned is the concept of a culture of organisational resilience being mandated by CEOs (7). CISOs now talk about culture change in cyber security, making business colleagues identify as part of the overall security of the organisation. This may now include resilience. Again, this may provide a vehicle for change for CISOs.
Risk as a factor when assessing whether to do business with third parties (4) will highlight the third-party dependency issues that now concern CISOs. The perimeter is now long gone; security extends beyond the organisational remit of the CISO. The ability to understand and collaborate with third party security will become n increasing requirement. There is a downside for CISOs. Many are already burdened with the need to report on compliance and audits. This may increase as requests come in from business partners, current and potential, on the organisation’s cyber security posture.
Related to compliance and reporting is the issue of Privacy. It is predicted the consumer privacy will increase to cover most countries (1). This may require additional focus on the extent and scope to which Privacy is reported. Many CISOs address this already due to requirements such as GDPR. This may provide a strong basis to move forward. CISOs have seen Privacy as a positive. “Do you really need that data?” is a question often asked. Organisations can reduce the amount of unwanted data stored and needing security.
Responding to attacks and the relentless change in tactics is an additional trend. Payments for ransomware is contentious. From the morale, legal and practical aspects of making payments. If this becomes regulated (5) it may provide a clearer basis for decision making. Perhaps it may provide a for of deterrent for attacks. If the victim cannot pay why attack them? Perhaps this is just wishful thinking. On the negative side attackers may increase the capability of their tools in the operational technology environment with extreme impact (6). A current area of concern for CISOs that may increase in focus.
On a positive side a majority of organisation will adopt zero trust as a starting point for their security (3). However, many will not gain the benefits. CISOs are now increasing addressing the organisational and cultural change required to make Zero Trust succeed and realising it is not just about the technology. There are clear benefits that have been identified in Cisco research papers1. CISOs are looking to introduce new consolidated technologies in web, cloud services and private application access (3). This may reduce tech debt, enable smoother operational management, centralised policy control and better reporting.

Microsoft has released its final monthly batch of security updates for 2022, fixing more than four dozen security holes in its various Windows operating systems and related software. The most pressing patches include a zero-day in a Windows feature that tries to flag malicious files from the Web, a critical bug in PowerShell, and a dangerous flaw in Windows 11 systems that was detailed publicly prior to this week’s Patch Tuesday.
The security updates include patches for Azure, Microsoft Edge, Office, SharePoint Server, SysInternals, and the .NET framework. Six of the update bundles earned Microsoft’s most dire “critical” rating, meaning they fix vulnerabilities that malware or malcontents can use to remotely commandeer an unpatched Windows system — with little to no interaction on the part of the user.
The bug already seeing exploitation is CVE-2022-44698, which allows attackers to bypass the Windows SmartScreen security feature. The vulnerability allows attackers to craft documents that won’t get tagged with Microsoft’s “Mark of the Web,” despite being downloaded from untrusted sites.
“This means no Protected View for Microsoft Office documents, making it easier to get users to do sketchy things like execute malicious macros, said Greg Wiseman, product manager at security firm Rapid7. This is the second Mark of the Web flaw Microsoft has patched in as many months; both were first publicly detailed over the past two months on Twitter by security researcher Will Dormann.
Publicly disclosed (but not actively exploited for now) is CVE-2022-44710, which is an elevation of privilege flaw in the DirectX graphics component of Windows 11.
Another notable critical bug is CVE-2022-41076, a remote code execution flaw in PowerShell — a key component of Windows that makes it easier to automate system tasks and configurations.
Kevin Breen at Immersive Labs said while Microsoft doesn’t share much detail about CVE-2022-41076 apart from the designation ‘Exploitation More Likely,’ they also note that successful exploitation requires an attacker to take additional actions to prepare the target environment.
“What actions are required is not clear; however, we do know that exploitation requires an authenticated user level of access,” Breen said. “This combination suggests that the exploit requires a social engineering element, and would likely be seen in initial infections using attacks like MalDocs or LNK files.”
Speaking of malicious documents, Trend Micro’s Zero Day Initiative highlights CVE-2022-44713, a spoofing vulnerability in Outlook for Mac.
“We don’t often highlight spoofing bugs, but anytime you’re dealing with a spoofing bug in an e-mail client, you should take notice,” ZDI’s Dustin Childs wrote. “This vulnerability could allow an attacker to appear as a trusted user when they should not be. Now combine this with the SmartScreen Mark of the Web bypass and it’s not hard to come up with a scenario where you receive an e-mail that appears to be from your boss with an attachment entitled “Executive_Compensation.xlsx”. There aren’t many who wouldn’t open that file in that scenario.”
Microsoft also released guidance on reports that certain software drivers certified by Microsoft’s Windows Hardware Developer Program were being used maliciously in post-exploitation activity.
Three different companies reported evidence that malicious hackers were using these signed malicious driver files to lay the groundwork for ransomware deployment inside victim organizations. One of those companies, Sophos, published a blog post Tuesday detailing how the activity was tied to the Russian ransomware group Cuba, which has extorted an estimated $60 million from victims since 2019.
Of course, not all scary and pressing security threats are Microsoft-based. Also on Tuesday, Apple released a bevy of security updates to iOS, iPadOS, macOS, tvOS and Safari, including a patch for a newly discovered zero-day vulnerability that could lead to remote code execution.
Anyone responsible for maintaining Fortinet or Citrix remote access products probably needs to update, as both are dealing with active attacks on just-patched flaws.
For a closer look at the patches released by Microsoft today (indexed by severity and other metrics) check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
A new year is almost upon us and as we look back on our accomplishments in 2022, we also look forward to helping our customers become more security resilient and be better prepared for 2023. As part of this forward-looking process, and with the help of Gartner Peer Insights, we surveyed 100 Security and IT professionals to understand their level of security maturity and obtain their perspective on the future.
The results of the survey, called “Gartner Peer Insights – Future of Endpoint Security” can be found here in Infographic form.
Key insights from the Survey:
Regarding the first key insight, approximately two-thirds of the organizations surveyed have implemented EDR and XDR capabilities. These two capabilities are critical to detecting and eliminating threats, either before a breach has occurred or before a breach has had an opportunity to create damage.
Another key insight is related to endpoint vendor selection. In the survey, it’s noted that the top criterion organizations are looking for when selecting an endpoint security solution is the ability to support a hybrid workforce. This isn’t surprising given the events that have occurred over the last few years and the mix of remote workers expanding to working from home. Many organizations feel that the hybrid workforce is here to stay, in varying levels of remote workforce vs. on-premises workforce. The obvious implications directly related to the endpoint solutions are flexibility (e.g., deployment options), scalability, efficacy, resilience, and manageability, as a few examples.
The survey infographic provides much more insights than these two examples. The good news is that Cisco Secure Endpoint meets the challenges ahead for 2023 and beyond. If you haven’t researched Secure Endpoint lately, go here to see What’s New.

Watch ThreatWise TV: Explorations in the spam folder
The spam folder: that dark and disregarded corner of every email account, full of too-good-to-be-true offers, unexpected shipments, and supposedly free giveaways.
You’re right to ignore this folder; few good things come from exploring it. But every once in a while one of these misleading, and sometimes malicious, emails manages to evade the filters that normally siphon them off, landing them in your inbox instead.
Fortunately, it’s easy enough to spot these emails if you know what to look for. We’ve investigated this folder once before, showcasing a variety of scams. With the holiday season in full swing, we thought this would be a good time to revisit how scammers are trying to trick unsuspecting users.
The holiday season is traditionally a time when this type of activity increases, and this year is no different. According to research published by credit reporting agency TransUnion, the average daily number of suspected digital fraud attempts was up 82 percent globally between Thanksgiving and Cyber Monday (Nov 24–Nov 28) compared to the rest of the year (Jan 1–Nov 23) and 127 percent higher for transactions originating in the US.
This level of activity makes it all the more important to be aware of these scams. With that in mind, let’s dive into the spam folder to get a picture of the types of campaigns currently circulating.
While much of the spam circulating is innocuous, many emails are phishing attempts, and some are indeed malicious. To explore these scams, we used a dedicated computer, segmented from the rest of the network, and leveraged Cisco Secure Malware Analytics to safely open the emails before clicking on links or opening attachments. The point being, we do not recommend doing this at home.
By far, the largest category of spam we saw were surveys scams. According to these emails, if you fill out a simple survey you’ll receive “exclusive offers” such as gift cards, smartphones, smart watches, power drills, or even pots and pans.
There are even some campaigns that specifically target the holiday shopping season.
Clicking the links in these emails takes the recipient to sites where they are asked to fill out a survey.
These pages often include fake testimonials that say how easy the survey is and what they did with their free gift.
The surveys are straightforward, comprising 10-20 simple questions that cover demographic information and shopping habits.
After the survey is completed, these sites offer the choice of a handful of rewards. All the recipient must do is pay for shipping. They are then brought to a page where they can fill out shipping and payment information, and the reward is supposedly shipped.
However, the attempts to make payment often appear to fail, or the recipient is informed that the prize is no longer available.
An unsuspecting user may simply give up at this point, disappointed that they won’t be getting their free gift. What they may not be aware of, is that they have just given their credit card details away in a phishing scam.
In their 2021 Internet Crime Report, the Internet Crime Complaint Center (IC3) said that Non-Payment / Non-Delivery scams such as these led to more than $337 million in losses, up from $265 million in 2020. Credit card fraud amounted to $172 million in 2021 and has been climbing continuously at a conservative rate of 15-20 percent since 2019.
According to Cisco Umbrella, many of the sites asking for credit card details are known phishing sites, or worse, host malware.
Another topic that we covered the last time we explored these types of scams was package delivery spam. These continue to circulate today. There are a variety of shipping companies impersonated in these campaigns, and some generic ones as well.
Many of these campaigns claim that a package could not be delivered. If the recipient clicks on a link in an email, they’re brought to a web page that explains that there are outstanding delivery fees that need to be paid.
The recipient is further enticed by suggestions that the package contains a big-ticket item, such as an iPhone or iPad Pro. All the recipient is required to do is enter their credit card details to cover the shipping.
While no outright malicious activity was detected while examining these emails in Secure Malware Analytics, several suspicious behaviors were flagged. Chances are the bad actors behind these campaigns are phishing for credit card details.
Sometimes the simplest approaches can work just as well as the flashiest. This certainly holds true with spam campaigns, given the prominence of plain-text messages.
The topics covered in such emails run the gamut, including medical cures, 419 scams, romance and dating, pharmaceuticals, weight loss, and many of the scam types we’ve already covered. Many of these link to phishing sites, though some attempt to establish a dialog with the recipient, tricking them into sending the scammers money.
The IC3 report says that victims of confidence fraud and romance scams lost $956 million collectively, which is up from $600 million in 2020. Healthcare fraud, such as the miracle pills and prescriptions scams, resulted in $7 million in losses in 2021, but nearly $30 million in 2020. While these types of scams seem generic and easily spotted, they still work, and so it’s important to be aware and avoid them.
Many emails hitting the spam box attempt to trick users of various services into believing that there is a problem with their account. The problems cover all sorts of services, including streaming platforms, email providers, antivirus subscriptions, and even public records.
If the links are clicked, the recipient is presented with landing pages that mimic the respective services. Any details that are entered will likely be phished, leading to account takeover and/or access to personal records. However, some domains encountered in these cases may do more than just steal information, they could deliver malware too.
Another frequently encountered scam surrounds billing. Many of these appear to be unexpected bills for services the recipient never purchased.
These emails include attachments that are designed to look like official invoices. Interestingly, most of the attachments that we looked at this time were harmless. The goal is to get the recipient to call what appears to be a toll-free number.
While we haven’t called any of these numbers, the experience usually unfolds like a standard customer service call. In the end the “agents” simply claim the charges—which never existed in the first place—have been removed. Meanwhile the scammers steal any personal or financial information provided during the call.
While most billing scams we encountered played out as described above, a few did indeed contain malware.
In this example, the email appears to come from an internet service provider, informing us that our monthly bill is ready.
An invoice appears to be attached, stored within a .zip file. If the recipient opens it and double clicks the file within, a command prompt appears.
This may seem unusual to the recipient, especially since no invoice appears, but by this point it’s too late. The file contains a script that launches PowerShell and attempts to download a remote file.
While the remote file was no longer available at the time of analysis, there is a high likelihood it was malicious. But even though we were unable to determine its contents, Secure Malware Analytics flagged the script execution as malicious.
Knowing about prevalent scams, especially during the holiday season, is a first step in guarding against them. Granted the bad actors who distribute these spam campaigns do everything they can to make their scams look legitimate.
Fortunately, there are several things that you can do to identify scams and defend against them:
But even the best of us can be fooled, and when overseeing a large operation it’s more a matter of when, rather than if, someone clicks on the wrong link. There are elements of the Cisco Secure portfolio that can help for when the inevitable happens.

Ampol has been Australia’s leading transport fuel company since 1900. What began over 125 years ago is now an organization that powers a country, operating 1,500 retail stores and stations across ANZ, plus 89 depots for refining and importing fuels and lubricants, and 8,200 employees throughout Australia, New Zealand, the United States, and Singapore. And while Ampol’s history goes back a century, they are a modern organization, using internet of things (IoT) technology across operational and retail locations, with sensors on everything from electric vehicle charging units to fuel tank gauges to transportation trucks to refrigeration units inside retail stores.
As a critical energy provider to a country of over 25 million people, Ampol’s security needed to match its evolving infrastructure. As Satish Chowdhary, Network Enterprise Architect, said, “At Ampol, we have implemented sensor technology across our network: from gauges in the fuel tanks to monitor fuel quality and quantity to sensors that monitor the temperature in various refrigerators across our retail sites to ensure goods stay chilled. It’s critical to manage these devices effectively and securely, and that’s where Cisco comes in…With IoT, a major security risk is posed by dodgy legacy devices left unpatched and vulnerable within your network. Cisco’s TrustSec and VLAN segregation automatically isolate vulnerable devices, not exposing the rest of the network to risks from untrusted devices.”
In addition to securing the IoT that let’s Ampol monitor and manage its critical operations, Cisco was able to create a comprehensive security environment that solved for their three strategic goals.
“Three key components of our cyber-resilient strategy were isolation, orchestration, and rapid recovery. Cisco SecureX nailed all three providing us a single interface to see all security events, and malicious files, thus expediting how fast we can isolate events and recover,” Chowdhary explained. “Before using Cisco Secure, security was a hindrance, not an enabler for our IT team, employees, and even customers,” he added.
In fact, Cisco Secure helped Ampol improve their security posture so much that they were able to quickly pivot during the early days of the pandemic.
“When Covid triggered supply challenges during lockdowns, people not being able to access groceries turned to their local service station convenience stores to get what they needed. For Ampol, maintaining that supply continuity was critical, not just for our business, but for the customers who were relying on us to get their supplies. And all of this was done when many employees were now having to work remotely… This was possible only because we could maintain our revamped locations, staff, clients, and business partners safe on our network – while still maintaining speed and efficiency. Cisco Secure was the ticket to Ampol’s resilience in the face of major change,” Chowdhary said.
In addition to enabling flexibility against supply chain fluctuations, Ampol is readily protected against threats, cyberattacks, and other vulnerabilities. Their Cisco security solution included:
“The major force for our Cisco Secure investment was simplification by integrating the entire Security portfolio…If we ever happen to have a cyber-attack, we can quickly find it and contain it,” Chowdhary said, adding, “The greatest outcome of using Cisco Secure is simplicity at its core. We achieved great efficiency integration, better visibility, and context that’s not hidden across five, ten, or fifteen consoles, and ultimately, greater security outcomes.”

In the second part of this blog series on Unscrambling Cybersecurity Acronyms, we covered Endpoint Detection and Response (EDR) and Managed Endpoint Detection and Response (MEDR) solutions, which included an overview of the evolution of endpoint security solutions. In this blog, we’ll go over Managed Detection and Response (MDR) and Extended Detection and Response (XDR) solutions in more depth.
MDR solutions are a security technology stack delivered as a managed service to customers by third-parties such as cybersecurity vendors or Managed Service Providers (MSPs). They’re similar to Managed Endpoint Detection and Response (MEDR) solutions since both solutions are managed cybersecurity services that use Security Operations Center (SOC) experts to monitor, detect, and respond to threats targeting your organization. However, the main difference between these two offerings is that MEDR solutions monitor only your endpoints while MDR solutions monitor a broader environment.
While MDR security solutions don’t have an exact definition for the types of infrastructure they monitor and the underlying security stack that powers them, they often monitor your endpoint, network, and cloud environments via a ‘follow the sun’ approach that uses multiple security teams distributed around the world to continually defend your environment. These security analysts monitor your environment 24/7 for threats, analyze and prioritize threats, investigate potential incidents, and offer guided remediation of attacks. This enables you to quickly detect advanced threats, effectively contain attacks, and rapidly respond to incidents.
More importantly, MDR security solutions allow you to augment or outsource your security to cybersecurity experts. While nearly every organization must defend their environment from cyberattacks, not every organization has the time, expertise, or personnel to run their own security solution. These organizations can benefit from outsourcing their security to MDR services, which enable them to focus on their core business while getting the security expertise they need. In addition, some organizations don’t have the budget or resources to monitor their environment 24/7 or they may have a small security team that struggles to investigate every threat. MDR security services can also help these organizations by giving them always-on security operations while enabling them to address every threat to their organization.
One drawback to deploying an MDR security service is that you become dependent on a third-party for your security needs. While many organizations don’t have any issues with this, some organizations may be hesitant to hand over control of their cybersecurity to a third-party vendor. In addition, organizations such as larger, more-risk averse companies may not desire an MDR service because they’ve already made cybersecurity investments such as developing their own SOC. Finally, MDR security solutions don’t have truly unified detection and response capabilities since they’re typically powered by heterogenous security technology stacks that lack consolidated telemetry, correlated detections, and holistic incident response. This is where XDR solutions shine.
XDR solutions unify threat monitoring, detection, and response across your entire environment by centralizing visibility, delivering contextual insights, and coordinating response. While ‘XDR’ means different things to different people because it’s a fairly nascent technology, XDR solutions usually consolidate security telemetry from multiple security products into a single solution. Moreover, XDR security solutions provide enriched context by correlating alerts from different security solutions. Finally, comprehensive XDR solutions can simplify incident response by allowing you to automate and orchestrate threat response across your environment.
These solutions speed up threat detection and response by providing a single pane of glass for gaining visibility into threats as well as detecting and responding to attacks. Furthermore, XDR security solutions reduce alert fatigue and false positives with actionable, contextual insights from higher-fidelity detections that mean you spend less time sifting through endless alerts and can focus on the most critical threats. Finally, XDR solutions enable you to streamline your security operations with improved efficiency from automated, orchestrated response across your entire security stack from one unified console.
A major downside to XDR security solutions is that you typically have to deploy and manage these solutions yourself versus having a third-party vendor run them for you. While Managed XDR (MXDR) services are growing, these solutions are still very much in their infancy. In addition, not every organization will want or need a full-fledged XDR solution. For instance, organizations with a higher risk threshold may be satisfied with using an EDR solution and/or an MDR service to defend their organization from threats.
As I mentioned in the first and second parts of this blog series, you shouldn’t take a ‘one-size-fits-all’ approach to cybersecurity since every organization has different needs, goals, risk appetites, staffing levels, and more. This logic holds true for MDR and XDR solutions, with these solutions working well for certain organizations and not so well for other organizations. Regardless, there are a few aspects to consider when evaluating MDR and XDR security solutions.
One factor to keep in mind is if you already have or are planning on building out your own SOC. This is important to think about because developing and operating a SOC can require large investments in cybersecurity, which includes having the right expertise on your security teams. Organizations unwilling to make these commitments usually end up choosing managed security services such as MDR solutions, which allows them to protect their organization without considerable upfront investments.
Other critical factors to consider are your existing security maturity and overall goals. For instance, organizations who have already made significant commitments to cybersecurity often think about ways to improve the operational efficiency of their security teams. These organizations frequently turn to XDR tools since these solutions reduce threat detection and response times, provide better visibility and context while decreasing alert fatigue. Moreover, organizations with substantial security investments should consider open and extensible XDR solutions that integrate with their existing tools to avoid having to ‘rip and replace’ security tools, which can be costly and cumbersome.
I hope this blog series on the different threat detection and response solutions help you make sense of the different cybersecurity acronyms while guiding you in your decision on the right security solution for your organization. For more information on MDR solutions, read about how Cisco Secure Managed Detection and Response (MDR) rapidly detects and contains threats with an elite team of security experts.

Lots of exciting things happening at Cisco, and for our customers, all to help them better prepare for what’s next. Case in point, we just returned from a very successful Cisco Partner Summit where the spotlight shined on cyber security. When our executives were on stage talking about solutions, the attendees heard a very catchy phrase; “if it’s connected, it’s protected.” A cool phrase, but there is more to that phrase and much more behind it.
To tie both connected and protected together, it’s good to note that Cisco is uniquely positioned as a security vendor with 80% of the worldwide internet traffic running through our network hardware and secured by our open platform, with hundreds of thousands of customers benefitting from automation, and from enriched and prioritized threat intel via our Extended Detection and Response (XDR) capabilities. That means a vast amount of unique insights for our customers to become more resilient, stay ahead of threats, be more confident, and benefit from less risk.
As examples of these questions above:
(1) what about proof points on the above?
(2) and do Cisco’s capabilities align with what customers want and need?
Let’s find out on the first by bringing the XDR aspect of security into the discussion, and the second by observing responses from a Forrester Total Economic Impact
(TEI) study commissioned by Cisco, both points utilizing our Secure Endpoint solution.
First off, in simple terms, XDR provides the benefit of integrating threat intel from all control points of the security platform and combines that into actionable insights for better, faster, and where appropriate, prioritized remediation of the most critical threats, i.e. XDR helps security teams to identify the threats that can do the most damage and enables the workflows to neutralize those threats first.
And here is where the proof point comes in. One of the most critical components of XDR is endpoint security. And in the case of Cisco, it’s our Secure Endpoint solution. Cisco recently participated in the AV-Comparatives’ Endpoint Prevention and Response (EPR) Test. The AV-C test is described by that independent test organization as “… the most comprehensive test of EPR products ever performed.” Secure Endpoint was one of the 10 endpoint security products in the test that were subjected to 50 separate targeted attack scenarios, which used a variety of different techniques.
Here are the highlights of the AV-C EPR report where Cisco Secure Endpoint:
Stunning results and confidence building for our customers that Cisco is effective in endpoint security. Read the complete AV-C EPR Test Report here.
And then, what about the second proof point – is Cisco providing what customers want & need?
Cisco commissioned Forrester Consulting to perform an unbiased cost-benefit analysis of our Cisco Secure Endpoint product. The report yielded the highlights below, based upon a composite organization, and also includes 20+ outstanding customer quotes.
Here’s the Forrester TEI Study bottom line for the composite organization:
Very good results and again, confidence building for our customers that Cisco is effective in endpoint security. Read the Forrester “The Total Economic Impact Of Cisco Secure Endpoint” Study here.
One last thing, what about those customer quotes? Here are a couple of examples:

The word is out! Cisco Secure Endpoint’s effectiveness is off the charts in protecting your enterprise environment.
This is not just a baseless opinion; however, the facts are rooted in actual test results from the annual AV-Comparative EPR Test Report published in October 2022. Not only did Secure Endpoint knock it out of the park in enterprise protection; but Cisco Secure Endpoint obtained the lowest total cost of ownership (TCO) per agent at $587 over 5 years. No one else was remotely close in this area. More to come on that later.
If you are not familiar with the “AV-Comparatives Endpoint Prevention and Response Test is the most comprehensive test of EPR products ever performed. The 10 products in the test were subjected to 50 separate targeted attack scenarios, which used a variety of different techniques.”
These results are from an industry-respected third-party organization that assesses antivirus software and has just confirmed what we know and believe here at Cisco, which is our Secure Endpoint product is the industry’s best of the best.
Look for yourself at where we landed. That’s right, Cisco Secure Endpoint smashed this test, we are almost off the quadrant as one of the “Strategic Leaders”.
We ended up here for a combination of reasons, with the top being our efficacy in protecting our customers’ environments in this real-world test that emulates multi-stage attacks similar to MITRE’s ATT&CK evaluations which are conducted as part of this process (click here for an overview of MITRE ATT&CK techniques). Out of all the 50 scenarios tested, Secure Endpoint was the only product that STOPPED 100% of targeted threats toward enterprise users, which prevented further infiltration into the organization.
In addition, this test not only assesses the efficacy of endpoint security products but also analyzes their cost-effectiveness. Following up on my earlier remarks about achieving the lowest cost of ownership, the graph below displays how we stacked up against other industry players in this space including several well-known vendors that chose not to display their names due to poor results.
These results provide a meaningful proof point that Cisco Secure Endpoint is perfectly positioned to secure the enterprise as well as secure the future of hybrid workers.
Enriched with built-in Extended Detection and Response (XDR) capabilities, Cisco Secure Endpoint has allowed our customers to maintain resiliency when faced with outside threats.
As we embark on securing “what’s next” by staying ahead of unforeseen cyber threats of tomorrow, Cisco Secure Endpoint integration with the complete Cisco Secure Solutions portfolio allows you to move forward with the peace of mind that if it’s connected, we can and will protect it.

Just a few years ago when the topic of supporting offsite workers arose, some of the key conversation topics were related to purchase, logistics, deployment, maintenance and similar issues. The discussions back then were more like “special cases” vs. today’s environment where supporting workers offsite (now known as the hybrid workforce) has become a critical mainstream topic.
Now with the bulk of many organization’s workers off-premise, the topic of security and the ability of a security vendor to help support an organization’s hybrid workers has risen to the top of the selection criteria. In a soon to be released Cisco endpoint survey, it’s not surprising that the ability of a security vendor to make supporting the hybrid workforce easier and more efficient was the key motivating factor when organizations choose security solutions.
Today, when prospects and existing customers look at Cisco’s ability to support hybrid workers with our advanced security solution set and open platform, it’s quite clear that we can deliver on that promise. But, yes, good tools make it easier and more efficient, but the reality is that running a SOC or any security group, large or small, still takes a lot of work. Most organizations not only rely on advanced security tools but utilize a set of best practices to provide clarity of roles, efficiency of operation, and for the more prepared, have tested these best practices to prove to themselves that they are prepared for what’s next.
Knowing that not all organizations have this degree of security maturity and preparedness, we gathered a couple of subject matter experts together to discuss 5 areas of time-tested best practices that, besides the advanced tools offered by Cisco and others, can help your SOC (or small security team) yield actionable insights and guide you faster, and with more confidence, toward the outcomes you want.
In this webinar you will hear practical advice from Cisco technical marketing and a representative from our award winning Talos Threat Intelligence group, the same group who have created and are maintaining breach defense in partnership with Fortune 500 Security Operating Centers (SOC) around the globe.
You can expect to hear our 5 Best Practices recommendations on the following topics;

Ransomware is one of the most dangerous threats organizations face today, so it’s no wonder that Cisco Talos Incident Response named it the top threat of the year in 2021. These attacks continue to grow and become more advanced, with ransomware attacks growing by 13% over 2021 and a whopping 79% over 2020 so far this year (see Figure 1 below).1 Stopping ransomware attacks isn’t easy either, as adversaries continue to change their techniques and attacks become increasingly sophisticated.
Fortunately, Cisco Secure Endpoint defends your organization from ransomware by delivering security outcomes that enable you to radically simplify your security, maximize your security operations, and achieve peace of mind. Let’s dive deeper into each of these areas to better understand how Secure Endpoint can help your organization defend against ransomware attacks.
Cybersecurity has become increasingly complex due to the numerous security solutions deployed by organizations today. These disparate point-products increase complexity while creating security gaps because they require additional management overhead and typically don’t communicate with each other. This increases the burden on security operations teams since they must spend time managing these different solutions and filling in the gaps between tools rather than using their time to investigate and respond to threats
Cisco takes a very different approach to cybersecurity by looking at ransomware endpoint protection holistically, as part of an integrated security solution. For instance, Secure Endpoint includes built-in extended detection and response (XDR) capabilities from the Cisco SecureX platform that centralizes visibility in a single console, creates high-fidelity detections by correlating threats, and coordinates threat response across your entire security environment. In addition, Secure Endpoint unifies your security stack, simplifies management, and reduces agent fatigue because we’ve consolidated endpoint protection, cloud security, and remote access agents into a single agent.

One of the common themes we’ve heard from our customers is that their security operations teams are frequently overstretched. The ongoing cybersecurity skills shortage means that security teams have to do more with less and a vast number of security tools to manage along with inefficient security operations processes, often leading to burned-out security teams.
Cisco addresses these challenges by allowing you to get the most out of your security operations. For example, you can accelerate investigation and incident response with valuable vulnerability context since we’ve integrated risk-based vulnerability management from Kenna Security into Secure Endpoint. Moreover, Secure Endpoint includes advanced endpoint detection and response (EDR) capabilities via Orbital Advanced Search and built-in XDR from SecureX that enable you to rapidly detect, respond to, and contain ransomware attacks. Lastly, you can get the security expertise you need with proactive threat hunting from SecureX Threat Hunting, which uses an analyst-centric process to quickly spot hidden ransomware.
Check out how Secure Endpoint helps you maximize your security operations while defending your organization from ransomware attacks by watching this video:
Keeping up with the latest ransomware attacks can seem like an impossible challenge due to Ransomware-as-a-service (RaaS) kits which make it simple and lucrative to target organizations with ransomware and the evolving threat landscape, where attackers are continuously changing their methods to evade detection.
Cisco helps you stay ahead of the newest ransomware attacks and gives you the peace of mind you deserve by taking a comprehensive approach to ransomware endpoint protection. This means ensuring that you never have to go it alone with always-on security operations from Cisco Secure Endpoint Pro, a managed service that uses a team of Cisco security experts to perform the heavy lifting of securing your endpoints. It also includes offering advanced EDR and integrated XDR capabilities such as Orbital and SecureX to speed detection and response, simplify investigations, and quickly contain ransomware attacks before it’s too late. Finally, Secure Endpoint prevents initial ransomware infections with multifaceted prevention techniques such as machine learning, exploit prevention, and behavioral protection as well as actionable threat intelligence from the Cisco Talos research team.

In the first part of this blog series on Unscrambling Cybersecurity Acronyms, we provided a high-level overview of the different threat detection and response solutions and went over how to find the right solution for your organization. In this blog, we’ll do a deeper dive on two of these solutions – Endpoint Detection and Response (EDR) and Managed Endpoint Detection and Response (MEDR). However, first let’s take a look back at the history of endpoint security solutions and understand how we got EDR and MEDR security solutions.
The very first endpoint security solutions started out as anti-virus solutions (AV) with basic security functionality that relied heavily on signature-based detection. These solutions were effective against known threats where a signature was created, but ineffective against unknown threats such as new and emerging attacks. That meant that organizations struggled to stay ahead of attackers, who were continuously evolving their techniques to evade detection with new types of malware.
To address this problem, AV vendors added detection technologies such as heuristics, reputational analysis, behavioral protection, and even machine learning to their solutions, which became known as Endpoint Protection Platforms (EPP). These unified solutions were effective against both known and unknown threats and frequently used multiple approaches to prevent malware and other attacks from infecting endpoints.
As cyberattacks grew increasingly sophisticated though, many in the cybersecurity industry recognized that protection against threats wasn’t enough. Effective endpoint security had to include detection and response capabilities to quickly investigate and remediate the inevitable security breach. This led to the creation of EDR security solutions, which focused on post-breach efforts to contain and clean up attacks on compromised endpoints.
Today, most endpoint security vendors combine EPP and EDR solutions into a single, converged solution that provides holistic defense to customers with protection, detection, and response capabilities. Many vendors are also offering EDR as a managed service (also known as MEDR) to customers who need help in securing their endpoints or who don’t have the resources to configure and manage their own EDR solution. Now that we’ve gone over how endpoint security evolved into EDR and MEDR security solutions, let’s cover EDR and MEDR in more depth.
EDR solutions continuously monitor your endpoints for threats, alert you in case suspicious activity is detected, and allow you to investigate, respond to and contain potential attacks. Moreover, many EDR security solutions provide threat hunting functionality to help you proactively spot threats in your environment. They’re often coupled with or part of a broader endpoint security solution that also includes prevention capabilities via an EPP solution to protect against the initial incursion.
As a result, EDR security solutions enable you to protect your organization from sophisticated attacks by rapidly detecting, containing, and remediating threats on your endpoints before they gain a foothold in your environment. They give you deep visibility into your endpoints while effectively identifying both known and unknown threats. Furthermore, you can quickly contain attacks that get through your defenses with automated response capabilities and hunt for hidden threats that are difficult to detect.
While EDR provides several benefits to customers, it has some drawbacks. Chief among them is that EDR security solutions are focused on monitoring endpoints only versus monitoring a broader environment. This means that EDR solutions don’t detect threats targeting other parts of your environment such as your network, email, or cloud infrastructure. In addition, not every organization has the security staff, budget, and/or skills to deploy and run an EDR solution. This is where MEDR solutions come into play.
Managed EDR or MEDR solutions are EDR capabilities delivered as a managed service to customers by third-parties such as cybersecurity vendors or Managed Service Providers (MSPs). This includes key EDR functionality such as monitoring endpoints, detecting advanced threats, rapidly containing threats, and responding to attacks. These third-parties usually have a team of Security Operations Center (SOC) specialists who monitor, detect, and respond to threats across your endpoints around the clock via a ‘follow the sun’ approach to monitoring.
MEDR security solutions allow you to offload the work of securing your endpoints to a team of security professionals. Many organizations need to defend their endpoints from advanced threats but don’t necessarily have the desire, resources, or expertise to manage an EDR solution. In addition, a team of dedicated SOC experts with advanced security tools can typically detect and respond to threats faster than in-house security teams, all while investigating every incident and prioritizing the most critical threats. This enables you to focus on your core business while getting always-on security operations.
Similar to EDR though, one downside to MEDR security solutions is that they defend only your endpoints from advanced threats and don’t monitor other parts of your infrastructure. Moreover, while many organizations want to deploy EDR as a managed service, not everyone desires this. For example, larger and/or more risk-averse organizations who are looking to invest heavily in cybersecurity are typically satisfied with running their own EDR solution. Now, let’s discuss how to choose the right endpoint security solution when trying to defend your endpoints from threats.
As I mentioned in my previous blog, there isn’t a single correct solution for every organization. This logic applies to EDR and MEDR security solutions as well since each solution works well for different types of organizations, depending on their needs, resources, motivations, and more. Nevertheless, one major factor to consider is if you have or are willing to build out a SOC for your organization. This is important because organizations that don’t have or aren’t willing to develop a SOC usually gravitate towards MEDR solutions, which don’t require significant investments in cybersecurity.
Another factor to keep in mind is your security expertise. Even if you’re have or are willing to build a SOC, you may not have the right cybersecurity talent and skills within your organization. While you can always build out your security team, you may want to evaluate an MEDR solution because a lack of expertise makes it difficult to effectively manage an EDR solution. Finally, a common misconception is that you must choose between an EDR and a MEDR solution and that you cannot run both solutions. In reality, many organizations end up using both EDR and MEDR since MEDR solutions often complement EDR deployments.
I hope this information and key factors help you better understand EDR and MEDR solutions while acting as a guide to selecting the best endpoint security solution for your organization. For more details on the different cybersecurity acronyms and how to identify the right solution for your needs, stay tuned for the next blog in this series – Unscrambling Cybersecurity Acronyms: The ABCs of MDR and XDR Security. In the meantime, learn how Cisco Secure Endpoint stops threats with a comprehensive endpoint security solution that includes both advanced EDR and MEDR capabilities powered by an integrated security platform!

This month’s Patch Tuesday offers a little something for everyone, including security updates for a zero-day flaw in Microsoft Windows that is under active attack, and another Windows weakness experts say could be used to power a fast-spreading computer worm. Also, Apple has also quashed a pair of zero-day bugs affecting certain macOS and iOS users, and released iOS 16, which offers a new privacy and security feature called “Lockdown Mode.” And Adobe axed 63 vulnerabilities in a range of products.
Microsoft today released software patches to plug at least 64 security holes in Windows and related products. Worst in terms of outright scariness is CVE-2022-37969, which is a “privilege escalation” weakness in the Windows Common Log File System Driver that allows attackers to gain SYSTEM-level privileges on a vulnerable host. Microsoft says this flaw is already being exploited in the wild.
Kevin Breen, director of cyber threat research at Immersive Labs, said any vulnerability that is actively targeted by attackers in the wild must be put to the top of any patching list.
“Not to be fooled by its relatively low CVSS score of 7.8, privilege escalation vulnerabilities are often highly sought after by cyber attackers,” Breen said. “Once an attacker has managed to gain a foothold on a victim’s system, one of their first actions will be to gain a higher level of permissions, allowing the attacker to disable security applications and any device monitoring. There is no known workaround to date, so patching is the only effective mitigation.”
Satnam Narang at Tenable said CVE-2022-24521 — a similar vulnerability in the same Windows log file component — was patched earlier this year as part of Microsoft’s April Patch Tuesday release and was also exploited in the wild.
“CVE-2022-37969 was disclosed by several groups, though it’s unclear if CVE-2022-37969 is a patch-bypass for CVE-2022-24521 at this point,” Narang said.
Another vulnerability Microsoft patched this month — CVE-2022-35803 — also seems to be related to the same Windows log file component. While there are no indications CVE-2022-35803 is being actively exploited, Microsoft suggests that exploitation of this flaw is more likely than not.
Trend Micro’s Dustin Childs called attention to CVE-2022-34718, a remote code execution flaw in the Windows TCP/IP service that could allow an unauthenticated attacker to execute code with elevated privileges on affected systems without user interaction.
“That officially puts it into the ‘wormable’ category and earns it a CVSS rating of 9.8,” Childs said. “However, only systems with IPv6 enabled and IPSec configured are vulnerable. While good news for some, if you’re using IPv6 (as many are), you’re probably running IPSec as well. Definitely test and deploy this update quickly.”
Cisco Talos warns about four critical vulnerabilities fixed this month — CVE-2022-34721 and CVE-2022-34722 — which have severity scores of 9.8, though they are “less likely” to be exploited, according to Microsoft.
“These are remote code execution vulnerabilities in the Windows Internet Key Exchange protocol that could be triggered if an attacker sends a specially crafted IP packet,” wrote Jon Munshaw and Asheer Malhotra. “Two other critical vulnerabilities, CVE-2022-35805 and CVE-2022-34700 exist in on-premises instances of Microsoft Dynamics 365. An authenticated attacker could exploit these vulnerabilities to run a specially crafted trusted solution package and execute arbitrary SQL commands. The attacker could escalate their privileges further and execute commands as the database owner.”
Not to be outdone, Apple fixed at least two zero-day vulnerabilities when it released updates for iOS, iPadOS, macOS and Safari. CVE-2022-32984 is a problem in the deepest recesses of the operating system (the kernel). Apple pushed an emergency update for a related zero-day last month in CVE-2022-32983, which could be used to foist malware on iPhones, iPads and Macs that visited a booby-trapped website.
Also listed under active attack is CVE-2022-32817, which has been fixed on macOS 12.6 (Monterey), macOS 11.7 (Big Sur), iOS 15.7 and iPadOS 15.7, and iOS 16. The same vulnerability was fixed in Apple Watch in July 2022, and credits Xinru Chi of Japanese cybersecurity firm Pangu Lab.
“Interestingly, this CVE is also listed in the advisory for iOS 16, but it is not called out as being under active exploit for that flavor of the OS,” Trend Micro’s Childs noted. “Apple does state in its iOS 16 advisory that ‘Additional CVE entries to be added soon.’ It’s possible other bugs could also impact this version of the OS. Either way, it’s time to update your Apple devices.”
Apple’s iOS 16 includes two new security and privacy features — Lockdown Mode and Safety Check. Wired.com describes Safety Check as a feature for users who are at risk for, or currently experiencing, domestic abuse.
“The tool centralizes a number of controls in one place to make it easier for users to manage and revoke access to their location data and reset privacy-related permissions,” wrote Lily Hay Newman.
“Lockdown Mode, on the other hand, is meant for users who potentially face targeted spyware attacks and aggressive state-backed hacking. The feature comprehensively restricts any nonessential iOS features so there are as few potential points of entry to a device as possible. As more governments and repressive entities around the world have begun purchasing powerful commodity spyware to target individuals of particular importance or interest, iOS’s general security defenses haven’t been able to keep pace with these specialized threats.”
To turn on Lockdown Mode in iOS 16, go to Settings, then Privacy and Security, then Lockdown Mode. Safety Check is located in the same area.
Finally, Adobe released seven patches addressing 63 security holes in Adobe Experience Manager, Bridge, InDesign, Photoshop, InCopy, Animate, and Illustrator. More on those updates is here.
Don’t forget to back up your data and/or system before applying any security updates. If you experience glitches or problems installing any of these patches this month, please consider leaving a comment about it below; there’s a decent chance other readers have experienced the same and may chime in here with useful tips.
The hybrid work environment has been around for years, albeit not common but it existed. I can recall my first job where I was able to split my time working in an office and working from my makeshift home office. This was many moons ago as I will call it… pre-COVID-19.
Job seekers are certainly looking to have the flexibility of working from anywhere at any time – preferably in an environment of their choosing. Even though a hybrid workforce will provide people with the option to work from anywhere, those remote locations are sometimes in unsecured locations. Organizations must now reimagine a workforce that will need access to your internal collaboration tools along with access to your network from both on- and off-premises.
Cisco, a leader in equipping organizations with the right products for a hybrid workforce, provides the tools & services to protect your organization from bad threat actors.
With pervasive ransomware attacks, malware attacks, and email attacks, you must be ready and have not only a security solution but also a security analyst team ready to respond when an attack happens.
Securing access to your endpoint must be a top priority and your security analysts must be agile and have the right telemetry to provide around-the-clock monitoring and the ability to quickly respond to threats.
Cisco Secure Endpoint provides you with the visibility and ability to respond to threats by blocking them before they compromise your network. Combined with global, proactive threat hunting, leading-edge forensic/analytic capabilities, and reduced leading Mean Time To Detection (MTTD)/Mean Time To Resolution (MTTR) across the supply chain that no other vendor can parallel; why would you partner with any other company to secure and scale your unique hybrid workforce or workplace clients?

I am joined by Cisco Talos global Senior Threat Defense and Response Analyst, William (Bill) Largent who has over 20 plus years of infosec experience, specifically in network intrusion detection, traffic analysis, and signature/rule writing.
I will also be speaking with Eric Howard, Cisco Secure Technical Marketing Engineer Leader for the Security Platform and Response Group. Eric is a seasoned team leader in both Information Security Sales, and Product Management. He has built and led teams that apply deep technical understanding to business needs, initiatives, and strategies in both start-ups and established companies.
This is a conversation you do not want to skip! There were a lot of gems shared by these gentlemen that will get you where you need to be as a Security Analyst.

Security tools are only as good as the intelligence and expertise that feeds them. We’re very fortunate to have our security technologies powered by Cisco Talos, one of the largest and most trusted threat intelligence groups in the world. Talos is comprised of highly skilled researchers, analysts, and engineers who provide industry-leading visibility, actionable intelligence, and vulnerability research to protect both our customers and the internet at large.
The Talos team serves as a crucial pillar of our innovation — alerting customers and the public to new threats and mitigation tactics, enabling us to quickly incorporate protection into our products, and stepping in to help organizations with incident response, threat hunting, compromise assessments and more. Talos can also be found securing large-scale events such as the Super Bowl, and working with government and law enforcement organizations across the globe to share intelligence.
With Cisco’s vast customer base and broad portfolio — from routers and switches to email and endpoints — Talos has visibility into worldwide telemetry. Once a threat is seen, whether it’s a phishing URL or an IP address hosting malware, detections are created and indicators of compromise are categorized and blocked across our Cisco Secure portfolio.
Talos also leverages its unique insights to help society as a whole better understand and combat the cyberattacks facing us daily. During the war in Ukraine, the group has taken on the additional task of defending over 30 critical infrastructure providers in the country by directly managing and monitoring their endpoint security.
The reality of security today is that organizations must be constantly ready to detect and contain both known and unknown threats, minimize impact, and keep business going no matter what happens in the cyber realm. In light of hybrid work, evolving network architectures, and increasingly insidious attacks, all organizations must also be prepared to rapidly recover if disaster strikes, and then emerge stronger. We refer to this as security resilience, and Talos plays a critical role in helping our customers achieve it.
For several years, our integrated, cloud-native Cisco SecureX platform has been delivering extended detection and response (XDR) capabilities and more. SecureX allows customers to aggregate, analyze, and act on intelligence from disparate sources for a coordinated response to cyber threats.
Through the SecureX platform, intelligence from Talos is combined with telemetry from our customers’ environments — including many third-party tools — to provide a more complete picture of what’s going on in the network. Additionally, built-in, automated response functionality helps to speed up and streamline mitigation. This way, potential attacks can be identified, prioritized, and remediated before they lead to major impact.
For XDR to be successful, it must not only aggregate data, but also make sense of it. Through combined insights from various resources, SecureX customers obtain the unified visibility and context needed to rapidly prioritize the right threats at the right time. With SecureX, security analysts spend up to 90 percent less time per incident.
One of Australia’s largest universities, Deakin University, needed to improve its outdated security posture and transition from ad hoc processes to a mature program. Its small security team sought an integrated solution to simplify and strengthen threat defense.
With a suite of Cisco security products integrated through SecureX, Deakin University was able to reduce the typical investigation and response time for a major threat down from over a week to just an hour. The university was also able to decrease its response time for malicious emails from an hour to as little as five minutes.
“The most important outcome that we have achieved so far is that security is now a trusted function.”
– Fadi Aljafari, Information Security and Risk Manager, Deakin University
Also in the education space, AzEduNet provides connectivity and online services to 1.5 million students and 150,000 teachers at 4,300 educational institutions in Azerbaijan. “We don’t have enough staff to monitor every entry point into our network and correlate all the information from our security solutions,” says Bahruz Ibrahimov, senior information security engineer at AzEduNet.
The organization therefore implemented Cisco SecureX to accelerate investigations and incident management, maximize operational efficiency with automated workflows, and decrease threat response time. With SecureX, AzEduNet has reduced its security incidents by 80 percent.
“The integration with all our Cisco Secure solutions and with other vendors saves us response and investigation time, as well as saving time for our engineers.”
– Bahruz Ibrahimov, Senior Information Security Engineer, AzEduNet
The sophistication of attackers and sheer number of threats out there today make it extremely challenging for most cybersecurity teams to effectively stay on top of alerts and recognize when something requires their immediate attention. According to a survey by ESG, 81 percent of organizations say their security operations have been affected by the cybersecurity skills shortage.
That’s why Talos employs hundreds of researchers around the globe — and around the clock — to collect and analyze massive amounts of threat data. The group uses the latest in machine learning logic and custom algorithms to distill the data into manageable, actionable intelligence.
“Make no mistake, this is a battle,” said Nick Biasini, head of outreach for Cisco Talos, who oversees a team of global threat hunters. “In order to keep up with the adversaries, you really need a deep technical understanding of how these threats are constructed and how the malware operates to quickly identify how it’s changing and evolving. Offense is easy, defense is hard.”
Earlier this year, we unveiled our strategic vision for the Cisco Security Cloud to deliver end-to-end security across hybrid, multicloud environments. Talos will continue to play a pivotal role in our technology as we execute on this vision. In addition to driving protection in our products, Talos also offers more customized and hands-on expertise to customers when needed.
Cisco Talos Incident Response provides a full suite of proactive and emergency services to help organizations prepare for, respond to, and recover from a breach — 24 hours a day. Additionally, the recently released Talos Intel on Demand service delivers custom research unique to your organization, as well as direct access to Talos security analysts for increased awareness and confidence.
