Microsoft today issued software updates to fix at least five dozen security holes in Windows and supported software, including patches for two zero-day vulnerabilities that are already being exploited. Also, Adobe, Google Chrome and Apple iOS users may have their own zero-day patching to do.
On Sept. 7, researchers at Citizen Lab warned they were seeing active exploitation of a “zero-click,” zero-day flaw to install spyware on iOS devices without any interaction from the victim.
“The exploit chain was capable of compromising iPhones running the latest version of iOS (16.6) without any interaction from the victim,” the researchers wrote.
According to Citizen Lab, the exploit uses malicious images sent via iMessage, an embedded component of Apple’s iOS that has been the source of previous zero-click flaws in iPhones and iPads.
Apple says the iOS flaw (CVE-2023-41064) does not seem to work against devices that have its ultra-paranoid “Lockdown Mode” enabled. This feature restricts non-essential iOS features to reduce the device’s overall attack surface, and it was designed for users concerned that they may be subject to targeted attacks. Citizen Lab says the bug it discovered was being exploited to install spyware made by the Israeli cyber surveillance company NSO Group.
This vulnerability is fixed in iOS 16.6.1 and iPadOS 16.6.1. To turn on Lockdown Mode in iOS 16, go to Settings, then Privacy and Security, then Lockdown Mode.
Not to be left out of the zero-day fun, Google acknowledged on Sept. 11 that an exploit for a heap overflow bug in Chrome is being exploited in the wild. Google says it is releasing updates to fix the flaw, and that restarting Chrome is the way to apply any pending updates. Interestingly, Google says this bug was reported by Apple and Citizen Lab.
On the Microsoft front, a zero-day in Microsoft Word is among the more concerning bugs fixed today. Tracked as CVE-2023-36761, it is flagged as an “information disclosure” vulnerability. But that description hardly grasps at the sensitivity of the information potentially exposed here.
Tom Bowyer, manager of product security at Automox, said exploiting this vulnerability could lead to the disclosure of Net-NTLMv2 hashes, which are used for authentication in Windows environments.
“If a malicious actor gains access to these hashes, they can potentially impersonate the user, gaining unauthorized access to sensitive data and systems,” Bowyer said, noting that CVE-2023-36761 can be exploited just by viewing a malicious document in the Windows preview pane. “They could also conduct pass-the-hash attacks, where the attacker uses the hashed version of a password to authenticate themselves without needing to decrypt it.”
The other Windows zero-day fixed this month is CVE-2023-36802. This is an “elevation of privilege” flaw in the “Microsoft Streaming Service Proxy,” which is built into Windows 10, 11 and Windows Server versions. Microsoft says an attacker who successfully exploits the bug can gain SYSTEM level privileges on a Windows computer.
Five of the flaws Microsoft fixed this month earned its “critical” rating, which the software giant reserves for vulnerabilities that can be exploited by malware or malcontents with little or no interaction by Windows users.
According to the SANS Internet Storm Center, the most serious critical bug in September’s Patch Tuesday is CVE-2023-38148, which is a weakness in the Internet Connection Sharing service on Windows. Microsoft says an unauthenticated attacker could leverage the flaw to install malware just sending a specially crafted data packet to a vulnerable Windows system.
Finally, Adobe has released critical security updates for its Adobe Reader and Acrobat software that also fixes a zero-day vulnerability (CVE-2023-26369). More details are at Adobe’s advisory.
For a more granular breakdown of the Windows updates pushed out today, check out Microsoft Patch Tuesday by Morphus Labs. In the meantime, consider backing up your data before updating Windows, and keep an eye on AskWoody.com for reports of any widespread problems with any of the updates released as part of September’s Patch Tuesday.
Update: Mozilla also has fixed zero-day flaw in Firefox and Thunderbird, and the Brave browser was updated as well. It appears the common theme here is any software that uses a code library called “libwebp,” and that this vulnerability is being tracked as CVE-2023-4863.
“This includes Electron-based applications, for example – Signal,” writes StackDiary.com. “Electron patched the vulnerability yesterday. Also, software like Honeyview (from Bandisoft) released an update to fix the issue. CVE-2023-4863 was falsely marked as Chrome-only by Mitre and other organizations that track CVE’s and 100% of media reported this issue as “Chrome only”, when it’s not.”
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.

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.
I think it’s fair to say that come to next Australia Day, there needs to be a special award category for parents of young children who survived home learning during the lockdowns. Let’s be honest – it’s been brutal! So many parents had to juggle their own full-time work, running a household, AND supervising a day’s worth of learning for often, multiple children! Research from Macquarie University showed that many parents spent up to 14 hours a week in their role as home learning managers and 9/10 parents reported the experience as, quite understandably, stressful! As a mum of older teens and young adults – who are usually self-sufficient – I’m in awe!
But the good news is – things are on the improve! Our vaccine rates are amongst the best in the world, so lockdowns have been lifted and, drum roll… kids are back at school! I’ve always been a big fan of trying to find the silver lining of any situation and I think there are many we can take away from our COVID experience, particularly when it comes to digital parenting. I know of so many parents who have completely rethought their approach to managing kids and technology since the pandemic hit because of their home learning experience.
So, in the spirit of sharing and caring, I thought I’d round up some of the best ‘aha’ moments from parents who were forced to become expert home learning managers over multiple lockdowns. And make sure you take notes because there are some great learnings that we can apply to our digital parenting journey.
If you have never been ‘all in’ with your kids’ use of technology for both learning and socializing, then you need to get over this ASAP. Technology is the lifeblood of your kids’ lives. It’s how they connect, nurture friendships, and organize their social lives. I also recommend parents try to see technology through the eyes of their kids NOT just through our more ‘mature’ lens. It’s the best way of truly understanding just what a huge role it plays in their day-to-day lives. And don’t forget that technology is almost always used to set up in-person catchups! So, please don’t demonize it, it will only push your kids away.
I totally appreciate that many parents didn’t choose to be home learning ‘managers’ however many have shared with me how they now feel far more involved in their child’s life because of the experience. Seeing first-hand how your child’s day works, overhearing their conversations with teachers and peers (courtesy of Zoom), and being blown away by your offspring’s tech skills has given many parents incredible insight into their child.
I know of parents who have noticed learning issues and friendship problems all as a result of their home learning manager role! There’s nothing like being able to nip something in the bud before it becomes a big issue! So, stay involved and you’ll reap the rewards!
Confession – I have never been one of those parents who proactively organized park visits, bushwalks, and exercise regimes for my kids. But many of the parents who managed young children through a lockdown and resorted to becoming personal trainers reported that it paid dividends. So, now lockdowns are (hopefully!) history, don’t forget about the benefits of getting your kids to move. It’s hard to be on a screen when you are walking the dog, playing a game of family cricket, or bushwalking. I know it’s time-consuming but it’s so worth it!
As of 2 years ago, the average Aussie household had 17 internet-connected devices in tow so it’s no wonder keeping abreast of all the devices in your household feels like a full-time job! But with kids continuing to use their devices for both study and socializing, it’s essential that you give each device a ‘once over’ to minimize risks and prevent issues arising down the track.
Ensuring all their software is up to date is a great place to start. Also check that the default password has been changed and that there is some top-shelf security software installed to protect the device and, most importantly, its user! And while you are there, why not also ensure that each of their online accounts has its own distinct password? If you think they could manage a password manager, then it might be time to introduce them to one? Check out McAfee’s True Key – I couldn’t manage without it!
I think you’d be hard-pressed to find many parents keen to return to home learning. In fact, I think there may even be a revolt if we had to go back! But, knowing we have picked up some ‘nuggets of gold’ along the way makes it a little feel a little better! So, please embrace technology – it’s a fantastic way of connecting with your kids. But of course, keep your family’s usage in check and minimize the risks by giving each device a once-over.
Happy Digital Parenting!

The post What We’ve Learnt From Home Learning During Lockdown appeared first on McAfee Blog.
Welcome to the new normal. We’re all now living in a post-COVID-19 world characterized by uncertainty, mass home working and remote learning. The lines demarcating normal life have shifted abruptly – perhaps never to return. That’s not the worst that can happen, as we all know, but it does mean we all need to get used to new ways of living, working and studying from home. This has major implications for the online safety, security and privacy of our families.
To help you adapt to these new conditions while protecting what matters most, Trend Micro has developed a two-part blog series on “The New Normal.” Part 1 identifies the scope and specific cyber-threats of the new normal. Part 2 provides security tips and products to help address those threats.
In April, nearly 300 million Americans were estimated to be in government-mandated lockdown. Even as some businesses, municipalities and states begin to relax these rules, experts have warned of subsequent waves of the virus, which could result in new localized lockdowns. In short, a lot of people will continue to work from home, while their children, also at home, attempt to study remotely from their mobile devices.
This has considerable implications for how we spend our time. Without that morning commute to work or school, more of it than ever will involve sitting in front of a desktop, laptop, tablet or smartphone screen. Even the smart TV is enlisted. Dangers include

Unfortunately, the increase in working from home (WFH), especially for those not used to it, may lead to an increase in risky behavior, such as: using non-approved apps for work; visiting non work-related sites on work devices; and using personal devices to access work resources. Recent global Trend Micro research found that:

This is not about restricting your freedom to visit the sites you want to visit while at home. It’s about reducing the risk of exposing corporate data and systems to possible malware.
Unsurprisingly, there has also been a major uptick in the volume of cyber-threats targeting home users. With a captive audience to aim at, it’s a huge opportunity for cyber-criminals to steal your log-ins and personal data to sell to fraudsters, or even to steal corporate passwords and information for a potentially bigger pay-off. They are helped by the fact that many home workers may be more distracted than they usually would be at the office, especially if they have young children. Your kids may even share the same laptops or PCs as you, potentially visiting risky sites and/or downloading unapproved apps.
There’s also a chance that, unless you have a corporate machine at home, your personal computing equipment is less secure than the kit you had in the office. Add to that the fact that support from the IT department may be less forthcoming than usual, given that stretched teams are overwhelmed with requests, while themselves struggling to WFH. One recent report claimed that nearly half (47%) of IT security pros have been taken off some or all of their typical security tasks to support other IT-related jobs. In another, only 59% of respondents said they believe their cybersecurity team has the right tools and resources at home to perform their job effectively.
It’s time to step up and take security into your own hands. Stay on the lookout for the following threats.

So what’s a remote worker/concerned parent to do to protect themselves and the family in the midst of the “new normal?”
Read Part 2 in this mini-series, which we’re publishing simultaneously with Part 1, where we share some best practice advice on how to keep your digital lives and work systems safe from online threats during lockdown—and where we provide tools to help you do just that.
The post Top Tips For Home Cybersecurity And Privacy In A Coronavirus-Impacted World (Part 1) appeared first on .
The past few months have seen radical changes to our work and home life under the Coronavirus threat, upending norms and confining millions of American families within just four walls. In this context, it’s not surprising that more of us are spending an increasing portion of our lives online. But this brings with it some familiar cyber-risks. In Part 1 of this mini-series, we explained how cyber-criminals are looking to capitalize on these sweeping changes to society to further their own ends.
Now let’s take a look at what you can do to protect your family, your data, and access to your corporate accounts.
The bad guys are laser-focused on stealing your personal data and log-ins and increasingly see the remote worker as an easy target for leapfrogging into corporate networks. That’s not to mention the potential internet safety risks inherent in bored kids spending more time in front of their screens. To respond, you’ll need to create an equally focused “home security plan” governed by sensible policies and best practices. Here are some of the key areas to consider.
Protect your smart home and router
Increasingly, unprotected smart home devices are being targeted by cyber-criminals to turn into botnets to attack others. They might also provide sophisticated attackers with a stepping-stone into your corporate systems, via the home network. The home router, with its known flaws, is (after the modem) the digital front door to the smart home and the basis for your networking, so it should be first in any security strategy. Consider the following when tackling home network security:
|
|
Secure your home office
Cyber-criminals are primed to take advantage of distracted home workers and potentially less secure PCs/devices. Secure this environment by doing the following:
|
|
Stay safe from phishing
Phishing is the number one tactic used by attackers to trick you into installing malware or handing over your log-ins. Emails, text messages, social media messages and more are spoofed to appear as if sent by a legitimate company or contact. In response:
|
|
Use video conferencing safely
New videoconferencing platforms can introduce risk, especially if you’re not familiar with the default settings. Here’s how to stay safe when video conferencing:
|
|
Stay safe shopping and banking
Next, protect your financial information and stay safe from e-commerce fraud by doing the following:
|
|
Think about online safety for kids
They may be under your roof for more hours of the day than usual, but your children are also likely to be spending more time online. That means you need to have a measured conversation with them about internet safety, backed up with parental controls. Consider the following:
|
|
Mobile security best practices
Finally, sheltering at home has limits, particularly for restless kids. When they go to the store or out to the park, facemasks notwithstanding, they’re likely going to use their mobile devices, just as they’ll continue to do at home. Of course, you’re not exempt either from mobile threats. Ensure mobile security by

When it comes to protecting the home from security and privacy threats during lockdown, leave no stone unturned. Cyber-criminals will always look for the weak link in the chain and focus their efforts there. Network security is important, but it doesn’t replace the need for protection on each individual device. You’ll need to cover your router, network, smart devices, and all endpoints (PCs, laptops, mobiles and other devices). Here’s how Trend Micro can help:
