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.”

Please consider backing up your data and/or imaging your system before applying any updates. And feel free to sound off in the comments if you experience any problems as a result of these patches.
Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secure” error code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.
A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.
So, what exactly is going on when you see the “this connection is not private” error?
For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not private” error means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate.
Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.
In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.
While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.
SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL.
So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware.
Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.
If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.
Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.
Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.
As we continue to do more critical business online, we must also do our best to address the risks of the internet’s many conveniences.
A comprehensive cybersecurity tool like McAfee+ Ultimate can help protect you from online scams, identity theft, and phishing attempts, and ensure you always have a secure connection. McAfee helps keep your sensitive information out of the hands of hackers and can help you keep your digital data footprints lighter with personal data cleanup.
With McAfee’s experts on your side, you can enjoy everything the web offers with the confidence of total protection.

Just like the myriad expanding galaxies seen in the latest images from the James Webb space telescope, the cybersecurity landscape consists of a growing number of security technology vendors, each with the goal of addressing the continually evolving threats faced by customers today. In order to be effective, cybersecurity tools have to be collaborative—be it sharing relevant threat intelligence, device & user insights, acting on detection and remediation workflows, and more.
We at Cisco Secure have embraced this concept for a while now with our continually growing ecosystem of multi-vendor technology integrations. At the RSA Conference 2022 earlier this year, Jeetu Patel, Cisco’s Executive Vice President and General Manager of Security and Collaboration, spoke of how the ‘cybersecurity poverty line’ is widening and how malicious actors are taking advantage of this gaping hole to unleash persistent attacks. It is imperative that cybersecurity vendors interact with and collaborate with each other to lower this gap. To do this, security vendors must adopt open ecosystems of APIs to easily integrate with each other to provide effective ways for mutual customers to defend and react to cybersecurity attacks.
Like in prior years, this fiscal year 2022 saw us growing to include new ecosystem partners and integrations. With 22 new partners and 51 new integrations in our ecosystem, Cisco Secure Technical Alliance (CSTA) now boasts over 450 integrations, including technical integrations with Cisco Duo and Cisco Kenna. This allows our mutual customers the freedom to implement the cybersecurity tools of their choice with the knowledge that these tools can integrate with each other if they need to, thus realizing a better return on investment in their cybersecurity spending and improving cybersecurity posture.
In this annual round-up of our ecosystem, we congratulate our new partners in CSTA and existing partners as well, who have either created new integrations across our portfolio or augmented existing ones. For more details on each partner integration in this announcement, please read through the individual partner highlights below.

The Department of Homeland Security (DHS) is urging states and localities to beef up security around proprietary devices that connect to the Emergency Alert System — a national public warning system used to deliver important emergency information, such as severe weather and AMBER alerts. The DHS warning came in advance of a workshop to be held this weekend at the DEFCON security conference in Las Vegas, where a security researcher is slated to demonstrate multiple weaknesses in the nationwide alert system.
A Digital Alert Systems EAS encoder/decoder that Pyle said he acquired off eBay in 2019. It had the username and password for the system printed on the machine.
The DHS warning was prompted by security researcher Ken Pyle, a partner at security firm Cybir. Pyle said he started acquiring old EAS equipment off of eBay in 2019, and that he quickly identified a number of serious security vulnerabilities in a device that is broadly used by states and localities to encode and decode EAS alert signals.
“I found all kinds of problems back then, and reported it to the DHS, FBI and the manufacturer,” Pyle said in an interview with KrebsOnSecurity. “But nothing ever happened. I decided I wasn’t going to tell anyone about it yet because I wanted to give people time to fix it.”
Pyle said he took up the research again in earnest after an angry mob stormed the U.S. Capitol on Jan. 6, 2021.
“I was sitting there thinking, ‘Holy shit, someone could start a civil war with this thing,”’ Pyle recalled. “I went back to see if this was still a problem, and it turns out it’s still a very big problem. So I decided that unless someone actually makes this public and talks about it, clearly nothing is going to be done about it.”
The EAS encoder/decoder devices Pyle acquired were made by Lyndonville, NY-based Digital Alert Systems (formerly Monroe Electronics, Inc.), which issued a security advisory this month saying it released patches in 2019 to fix the flaws reported by Pyle, but that some customers are still running outdated versions of the device’s firmware. That may be because the patches were included in version 4 of the firmware for the EAS devices, and many older models apparently do not support the new software.
“The vulnerabilities identified present a potentially serious risk, and we believe both were addressed in software updates issued beginning Oct 2019,” EAS said in a written statement. “We also provided attribution for the researcher’s responsible disclosure, allowing us to rectify the matters before making any public statements. We are aware that some users have not taken corrective actions and updated their software and should immediately take action to update the latest software version to ensure they are not at risk. Anything lower than version 4.1 should be updated immediately. On July 20, 2022, the researcher referred to other potential issues, and we trust the researcher will provide more detail. We will evaluate and work to issue any necessary mitigations as quickly as possible.”
But Pyle said a great many EAS stakeholders are still ignoring basic advice from the manufacturer, such as changing default passwords and placing the devices behind a firewall, not directly exposing them to the Internet, and restricting access only to trusted hosts and networks.
Pyle, in a selfie that is heavily redacted because the EAS device behind him had its user credentials printed on the lid.
Pyle said the biggest threat to the security of the EAS is that an attacker would only need to compromise a single EAS station to send out alerts locally that can be picked up by other EAS systems and retransmitted across the nation.
“The process for alerts is automated in most cases, hence, obtaining access to a device will allow you to pivot around,” he said. “There’s no centralized control of the EAS because these devices are designed such that someone locally can issue an alert, but there’s no central control over whether I am the one person who can send or whatever. If you are a local operator, you can send out nationwide alerts. That’s how easy it is to do this.”
One of the Digital Alert Systems devices Pyle sourced from an electronics recycler earlier this year was non-functioning, but whoever discarded it neglected to wipe the hard drive embedded in the machine. Pyle soon discovered the device contained the private cryptographic keys and other credentials needed to send alerts through Comcast, the nation’s third-largest cable company.
“I can issue and create my own alert here, which has all the valid checks or whatever for being a real alert station,” Pyle said in an interview earlier this month. “I can create a message that will start propagating through the EAS.”
Comcast told KrebsOnSecurity that “a third-party device used to deliver EAS alerts was lost in transit by a trusted shipping provider between two Comcast locations and subsequently obtained by a cybersecurity researcher.
“We’ve conducted a thorough investigation of this matter and have determined that no customer data, and no sensitive Comcast data, were compromised,” Comcast spokesperson David McGuire said.
The company said it also confirmed that the information included on the device can no longer be used to send false messages to Comcast customers or used to compromise devices within Comcast’s network, including EAS devices.
“We are taking steps to further ensure secure transfer of such devices going forward,” McGuire said. “Separately, we have conducted a thorough audit of all EAS devices on our network and confirmed that they are updated with currently available patches and are therefore not vulnerable to recently reported security issues. We’re grateful for the responsible disclosure and to the security research community for continuing to engage and share information with our teams to make our products and technologies ever more secure. Mr. Pyle informed us promptly of his research and worked with us as we took steps to validate his findings and ensure the security of our systems.”
The user interface for an EAS device.
Unauthorized EAS broadcast alerts have happened enough that there is a chronicle of EAS compromises over at fandom.com. Thankfully, most of these incidents have involved fairly obvious hoaxes.
According to the EAS wiki, in February 2013, hackers broke into the EAS networks in Great Falls, Mt. and Marquette, Mich. to broadcast an alert that zombies had risen from their graves in several counties. In Feb. 2017, an EAS station in Indiana also was hacked, with the intruders playing the same “zombies and dead bodies” audio from the 2013 incidents.
“On February 20 and February 21, 2020, Wave Broadband’s EASyCAP equipment was hacked due to the equipment’s default password not being changed,” the Wiki states. “Four alerts were broadcasted, two of which consisted of a Radiological Hazard Warning and a Required Monthly Test playing parts of the Hip Hop song Hot by artist Young Thug.”
In January 2018, Hawaii sent out an alert to cell phones, televisions and radios, warning everyone in the state that a missile was headed their way. It took 38 minutes for Hawaii to let people know the alert was a misfire, and that a draft alert was inadvertently sent. The news video clip below about the 2018 event in Hawaii does a good job of walking through how the EAS works.
Whether using the internet for play or work, you want to spend your time online enjoying the peace of mind that comes with having a secure network.
You don’t want to contend with someone taking your personal data — whether it’s credit card information, passwords, or bank account details — via malware or a data breach on your Android, Windows, or Apple iOS device.
Fortunately, with some sensible precautions and simple steps, you can use your connected devices productively without worrying about cybercriminals and malicious software. This article explains how to stop hackers from getting access to your sensitive data.
You can take steps to protect your different computing and mobile devices and operating systems. These steps can be divided into technological solutions and the right awareness and information to provide a comforting measure of self-protection.
It’s like learning karate for self-defense, giving you confidence as you negotiate the wider world (and hoping that you never have to use it).
When it comes to identity protection software, McAfee provides a proven solution with our identity protection and privacy services. The protection includes alerts if your sensitive information is found on the dark web (up to 10 months sooner than other providers), personal data cleanup from sites gathering and selling your information, and an unlimited virtual public network (VPN) service that protects your privacy as you use public Wi-Fi networks.
You’ll also get up to $1 million in identity theft coverage and hands-on restoration support to help you reclaim your identity.
Simple, obvious passwords and passcodes (like your street address, your birthday, your kids’ or pets’ names, or “1234” or “abcd”) are easy for cybercriminals to crack, giving them unwanted access to your private data.
The stronger your password, the better your protection. Some best password practices include:
It’s important not to be a standing target. Just as you should use different passwords for everything, you should regularly change your passwords. You should do this a few times a year (although some cyber experts say this might not be necessary if you have a long and very complicated password).
If you have a number of passwords that you update often, it might be worth getting a password manager like McAfee True Key to keep track of them. Not only will you not be faced with remembering all your different passwords or writing them down (also a no-no), but it can also help you create and store unique passwords.
The software uses the strongest encryption algorithms available to protect your passwords, scrambling them so no one else can access them. It’ll also suggest new passwords and automatically log you into your online accounts with just one master password.
Another important line of defense is multi-factor authentication (sometimes known as two-factor authentication). This system uses a password and a second piece of verification — often an SMS message sent to your Android device or iPhone — to authenticate your identity.
This provides hard-to-beat protection even if a hacker has your password. Besides receiving SMS codes, there are also code-generating apps and physical security keys.
Thinking before you click on an email or text is a very important defense against phishing scams. Your bank won’t send you an email or text notifying you that there’s been suspicious activity on your account.
Does getting a large refund from your phone company sound too good to be true? It is. Similarly, the Internal Revenue Service (IRS) won’t text to tell you that you owe them money, and princes aren’t going to give you a fortune out of the blue.
Internet users beware: If you’re not absolutely certain that the text message you received is from a legitimate and trusted source, delete it. You can always contact the business or person directly to confirm that the message is legit.
Any operating system or app you use is open to malicious cyberattacks. This is why you should keep all your software up to date with the latest versions. Software developers are continually fixing holes in their products and offering cybersecurity patches to make them as safe and hacker-proof as possible.
Make sure your software, firmware, and security settings are up to date on your home’s Wi-Fi router, as well. You can often change your settings to allow for automatic updates.
Sure, who doesn’t like to go to a cafe, library, or hotel lobby to use the free Wi-Fi? But security is often weak in these public networks. If you open your online banking account or access personal information, you may unwittingly be giving a personal invitation to eavesdropping cybercriminals.
This is where the bank-grade level of protection of McAfee Secure VPN comes in, which automatically turns on when you need it and keeps you safe on public Wi-Fi networks.
Even if your device does get hacked, you can protect vital information on your Windows or macOS system with an encryption program like BitLocker or FileVault. You can protect any hard drive you use, including portable ones and USB keys.
It’s also a good idea to only shop at encrypted websites marked with the prefix “HTTPS” in their URLs.
One of the best ways to surf the web in comfort while keeping hackers at bay is with the comprehensive solutions provided by McAfee Total Protection.

The post How to Stay One Step Ahead of Hackers appeared first on McAfee Blog.
The U.S. Drug Enforcement Administration (DEA) says it is investigating reports that hackers gained unauthorized access to an agency portal that taps into 16 different federal law enforcement databases. KrebsOnSecurity has learned the alleged compromise is tied to a cybercrime and online harassment community that routinely impersonates police and government officials to harvest personal information on their targets.
Unidentified hackers shared this screenshot of alleged access to the Drug Enforcement Administration’s intelligence sharing portal.
On May 8, KrebsOnSecurity received a tip that hackers obtained a username and password for an authorized user of esp.usdoj.gov, which is the Law Enforcement Inquiry and Alerts (LEIA) system managed by the DEA.
KrebsOnSecurity shared information about the allegedly hijacked account with the DEA, the Federal Bureau of Investigation (FBI), and the Department of Justice, which houses both agencies. The DEA declined to comment on the validity of the claims, issuing only a brief statement in response.
“DEA takes cyber security and information of intrusions seriously and investigates all such reports to the fullest extent,” the agency said in a statement shared via email.
According to this page at the Justice Department website, LEIA “provides federated search capabilities for both EPIC and external database repositories,” including data classified as “law enforcement sensitive” and “mission sensitive” to the DEA.
A document published by the Obama administration in May 2016 (PDF) says the DEA’s El Paso Intelligence Center (EPIC) systems in Texas are available for use by federal, state, local and tribal law enforcement, as well as the Department of Defense and intelligence community.
EPIC and LEIA also have access to the DEA’s National Seizure System (NSS), which the DEA uses to identify property thought to have been purchased with the proceeds of criminal activity (think fancy cars, boats and homes seized from drug kingpins).
“The EPIC System Portal (ESP) enables vetted users to remotely and securely share intelligence, access the National Seizure System, conduct data analytics, and obtain information in support of criminal investigations or law enforcement operations,” the 2016 White House document reads. “Law Enforcement Inquiry and Alerts (LEIA) allows for a federated search of 16 Federal law enforcement databases.”
The screenshots shared with this author indicate the hackers could use EPIC to look up a variety of records, including those for motor vehicles, boats, firearms, aircraft, and even drones.
Claims about the purloined DEA access were shared with this author by “KT,” the current administrator of the Doxbin — a highly toxic online community that provides a forum for digging up personal information on people and posting it publicly.
As KrebsOnSecurity reported earlier this year, the previous owner of the Doxbin has been identified as the leader of LAPSUS$, a data extortion group that hacked into some of the world’s largest tech companies this year — including Microsoft, NVIDIA, Okta, Samsung and T-Mobile.
That reporting also showed how the core members of LAPSUS$ were involved in selling a service offering fraudulent Emergency Data Requests (EDRs), wherein the hackers use compromised police and government email accounts to file warrantless data requests with social media firms, mobile telephony providers and other technology firms, attesting that the information being requested can’t wait for a warrant because it relates to an urgent matter of life and death.
From the standpoint of individuals involved in filing these phony EDRs, access to databases and user accounts within the Department of Justice would be a major coup. But the data in EPIC would probably be far more valuable to organized crime rings or drug cartels, said Nicholas Weaver, a researcher for the International Computer Science Institute at University of California, Berkeley.
Weaver said it’s clear from the screenshots shared by the hackers that they could use their access not only to view sensitive information, but also submit false records to law enforcement and intelligence agency databases.
“I don’t think these [people] realize what they got, how much money the cartels would pay for access to this,” Weaver said. “Especially because as a cartel you don’t search for yourself you search for your enemies, so that even if it’s discovered there is no loss to you of putting things ONTO the DEA’s radar.”
The DEA’s EPIC portal login page.
The login page for esp.usdoj.gov (above) suggests that authorized users can access the site using a “Personal Identity Verification” or PIV card, which is a fairly strong form of authentication used government-wide to control access to federal facilities and information systems at each user’s appropriate security level.
However, the EPIC portal also appears to accept just a username and password, which would seem to radically diminish the security value of requiring users to present (or prove possession of) an authorized PIV card. Indeed, KT said the hacker who obtained this illicit access was able to log in using the stolen credentials alone, and that at no time did the portal prompt for a second authentication factor.
It’s not clear why there are still sensitive government databases being protected by nothing more than a username and password, but I’m willing to bet big money that this DEA portal is not only offender here. The DEA portal esp.usdoj.gov is listed on Page 87 of a Justice Department “data inventory,” which catalogs all of the data repositories that correspond to DOJ agencies.
There are 3,330 results. Granted, only some of those results are login portals, but that’s just within the Department of Justice.
If we assume for the moment that state-sponsored foreign hacking groups can gain access to sensitive government intelligence in the same way as teenage hacker groups like LAPSUS$, then it is long past time for the U.S. federal government to perform a top-to-bottom review of authentication requirements tied to any government portals that traffic in sensitive or privileged information.
I’ll say it because it needs to be said: The United States government is in urgent need of leadership on cybersecurity at the executive branch level — preferably someone who has the authority and political will to eventually disconnect any federal government agency data portals that fail to enforce strong, multi-factor authentication.
I realize this may be far more complex than it sounds, particularly when it comes to authenticating law enforcement personnel who access these systems without the benefit of a PIV card or government-issued device (state and local authorities, for example). It’s not going to be as simple as just turning on multi-factor authentication for every user, thanks in part to a broad diversity of technologies being used across the law enforcement landscape.
But when hackers can plunder 16 law enforcement databases, arbitrarily send out law enforcement alerts for specific people or vehicles, or potentially disrupt ongoing law enforcement operations — all because someone stole, found or bought a username and password — it’s time for drastic measures.
Conti — one of the most ruthless and successful Russian ransomware groups — publicly declared during the height of the COVID-19 pandemic that it would refrain from targeting healthcare providers. But new information confirms this pledge was always a lie, and that Conti has launched more than 200 attacks against hospitals and other healthcare facilities since first surfacing in 2018 under its earlier name, “Ryuk.”
On April 13, Microsoft said it executed a legal sneak attack against Zloader, a remote access trojan and malware platform that multiple ransomware groups have used to deploy their malware inside victim networks. More specifically, Microsoft obtained a court order that allowed it to seize 65 domain names that were used to maintain the Zloader botnet.
Microsoft’s civil lawsuit against Zloader names seven “John Does,” essentially seeking information to identify cybercriminals who used Zloader to conduct ransomware attacks. As the company’s complaint notes, some of these John Does were associated with lesser ransomware collectives such as Egregor and Netfilim.
But according to Microsoft and an advisory from the U.S. Cybersecurity & Infrastructure Security Agency (CISA), Zloader had a special relationship with Ryuk/Conti, acting as a preferred distribution platform for deploying Ryuk/Conti ransomware.
Several parties backed Microsoft in its legal efforts against Zloader by filing supporting declarations, including Errol Weiss, a former penetration tester for the U.S. National Security Agency (NSA). Weiss now serves as the chief security officer of the Health Information Sharing & Analysis Center (H-ISAC), an industry group that shares information about cyberattacks against healthcare providers.
Weiss said ransomware attacks from Ryuk/Conti have impacted hundreds of healthcare facilities across the United States, including facilities located in 192 cities and 41 states and the District of Columbia.
“The attacks resulted in the temporary or permanent loss of IT systems that support many of the provider delivery functions in modern hospitals resulting in cancelled surgeries and delayed medical care,” Weiss said in a declaration (PDF) with the U.S. District Court for the Northern District of Georgia.
“Hospitals reported revenue losses due to Ryuk infections of nearly $100 million from data I obtained through interviews with hospital staff, public statements, and media articles,” Weiss wrote. “The Ryuk attacks also caused an estimated $500 million in costs to respond to the attacks – costs that include ransomware payments, digital forensic services, security improvements and upgrading impacted systems plus other expenses.”
The figures cited by Weiss appear highly conservative. A single attack by Ryuk/Conti in May 2021 against Ireland’s Health Service Executive, which operates the country’s public health system, resulted in massive disruptions to healthcare in Ireland. In June 2021, the HSE’s director general said the recovery costs for that attack were likely to exceed USD $600 million.
Conti ravaged the healthcare sector throughout 2020, and leaked internal chats from the Conti ransomware group show the gang had access to more than 400 healthcare facilities in the U.S. alone by October 2020.
On Oct. 28, 2020, KrebsOnSecurity broke the news that FBI and DHS officials had seen reliable intelligence indicating the group planned to ransom many of these care facilities simultaneously. Hours after that October 2020 piece ran, I heard from a respected H-ISAC security professional who questioned whether it was worth getting the public so riled up. The story had been updated multiple times throughout the day, and there were at least five healthcare organizations hit with ransomware within the span of 24 hours.
“I guess it would help if I understood what the baseline is, like how many healthcare organizations get hit with ransomware on average in one week?” I asked the source.
“It’s more like one a day,” the source confided.
A report in February 2022 from Sophos found Conti orchestrated a cyberattack against a Canadian healthcare provider in late 2021. Security software firm Emsisoft found that at least 68 healthcare providers suffered ransomware attacks last year.
While Conti is just one of many ransomware groups threatening the healthcare industry, it seems likely that ransomware attacks on the healthcare sector are underreported. Perhaps this is because a large percentage of victims are paying a ransom demand to keep their data (and news of their breach) confidential. A survey published in February by email security provider Proofpoint found almost 60 percent of victims hit by ransomware paid their extortionists.
Or perhaps it’s because many crime groups have shifted focus away from deploying ransomware and toward stealing data and demanding payment not to publish the information. Conti shames victims who refuse to pay a ransom by posting their internal data on their darkweb blog.
Since the beginning of 2022, Conti has claimed responsibility for hacking a cancer testing lab, a medical prescription service online, a biomedical testing facility, a pharmaceutical company, and a spinal surgery center.
The Healthcare Information and Management Systems Society recently released its 2021 HIMSS Healthcare Cybersecurity Survey (PDF), which interviewed 167 healthcare cybersecurity professionals and found 67 percent had experienced a “significant security incident” in the past year.
The survey also found that just six percent or less of respondent’s information technology budgets were devoted to cybersecurity, although roughly 60 percent of respondents said their cybersecurity budgets would increase in 2022. Last year, just 79 percent of respondents said they’d fully implemented antivirus or other anti-malware systems; only 43 percent reported they’d fully implemented intrusion detection and prevention technologies.
The FBI says Conti typically gains access to victim networks through weaponized malicious email links, attachments, or stolen Remote Desktop Protocol (RDP) credentials, and that it weaponizes Microsoft Office documents with embedded Powershell scripts — initially staging Cobalt Strike via the Office documents and then dropping Emotet onto the network — giving them the ability to deploy ransomware. The FBI said Conti has been observed inside victim networks between four days and three weeks on average before deploying Conti ransomware.
