Microsoft today released updates to fix at least 86 security vulnerabilities in its Windows operating systems and other software, including a weakness in all supported versions of Windows that Microsoft warns is actively being exploited. The software giant also has made a controversial decision to put the brakes on a plan to block macros in Office documents downloaded from the Internet.
In February, security experts hailed Microsoft’s decision to block VBA macros in all documents downloaded from the Internet. The company said it would roll out the changes in stages between April and June 2022.
Macros have long been a trusted way for cybercrooks to trick people into running malicious code. Microsoft Office by default warns users that enabling macros in untrusted documents is a security risk, but those warnings can be easily disabled with the click of button. Under Microsoft’s plan, the new warnings provided no such way to enable the macros.
As Ars Technica veteran reporter Dan Goodin put it, “security professionals—some who have spent the past two decades watching clients and employees get infected with ransomware, wipers, and espionage with frustrating regularity—cheered the change.”
But last week, Microsoft abruptly changed course. As first reported by BleepingComputer, Redmond said it would roll back the changes based on feedback from users.
“While Microsoft has not shared the negative feedback that led to the rollback of this change, users have reported that they are unable to find the Unblock button to remove the Mark-of-the-Web from downloaded files, making it impossible to enable macros,” Bleeping’s Sergiu Gatlan wrote.
Microsoft later said the decision to roll back turning off macros by default was temporary, although it has not indicated when this important change might be made for good.
The zero-day Windows vulnerability already seeing active attacks is CVE-2022-22047, which is an elevation of privilege vulnerability in all supported versions of Windows. Trend Micro’s Zero Day Initiative notes that while this bug is listed as being under active attack, there’s no information from Microsoft on where or how widely it is being exploited.
“The vulnerability allows an attacker to execute code as SYSTEM, provided they can execute other code on the target,” ZDI’s Dustin Childs wrote. “Bugs of this type are typically paired with a code execution bug, usually a specially crafted Office or Adobe document, to take over a system. These attacks often rely on macros, which is why so many were disheartened to hear Microsoft’s delay in blocking all Office macros by default.”
Kevin Breen, director of cyber threat research at Immersive Labs, said CVE-2022-22047 is the kind of vulnerability that is typically seen abused after a target has already been compromised.
“Crucially, it allows the attacker to escalate their permissions from that of a normal user to the same permissions as the SYSTEM,” he said. “With this level of access, the attackers are able to disable local services such as Endpoint Detection and Security tools. With SYSTEM access they can also deploy tools like Mimikatz which can be used to recover even more admin and domain level accounts, spreading the threat quickly.”
After a brief reprieve from patching serious security problems in the Windows Print Spooler service, we are back to business as usual. July’s patch batch contains fixes for four separate elevation of privilege vulnerabilities in Windows Print Spooler, identified as CVE-2022-22022, CVE-2022-22041, CVE-2022-30206, and CVE-2022-30226. Experts at security firm Tenable note that these four flaws provide attackers with the ability to delete files or gain SYSTEM level privileges on a vulnerable system.
Roughly a third of the patches issued today involve weaknesses in Microsoft’s Azure Site Recovery offering. Other components seeing updates this month include Microsoft Defender for Endpoint; Microsoft Edge (Chromium-based); Office; Windows BitLocker; Windows Hyper-V; Skype for Business and Microsoft Lync; and Xbox.
Four of the flaws fixed this month address vulnerabilities Microsoft rates “critical,” meaning they could be used by malware or malcontents to assume remote control over unpatched Windows systems, usually without any help from users. CVE-2022-22029 and CVE-2022-22039 affect Network File System (NFS) servers, and CVE-2022-22038 affects the Remote Procedure Call (RPC) runtime.
“Although all three of these will be relatively tricky for attackers to exploit due to the amount of sustained data that needs to be transmitted, administrators should patch sooner rather than later,” said Greg Wiseman, product manager at Rapid7. “CVE-2022-30221 supposedly affects the Windows Graphics Component, though Microsoft’s FAQ indicates that exploitation requires users to access a malicious RDP server.”
Separately, Adobe today issued patches to address at least 27 vulnerabilities across multiple products, including Acrobat and Reader, Photoshop, RoboHelp, and Adobe Character Animator.
For a closer look at the patches released by Microsoft today and 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.
Microleaves, a ten-year-old proxy service that lets customers route their web traffic through millions of Microsoft Windows computers, recently fixed a vulnerability in their website that exposed their entire user database. Microleaves claims its proxy software is installed with user consent, but data exposed in the breach shows the service has a lengthy history of being supplied with new proxies by affiliates incentivized to distribute the software any which way they can — such as by secretly bundling it with other titles.
The Microleaves proxy service, which is in the process of being rebranded to Shifter[.[io.
Launched in 2013, Microleaves is a service that allows customers to route their Internet traffic through PCs in virtually any country or city around the globe. Microleaves works by changing each customer’s Internet Protocol (IP) address every five to ten minutes.
The service, which accepts PayPal, Bitcoin and all major credit cards, is aimed primarily at enterprises engaged in repetitive, automated activity that often results in an IP address being temporarily blocked — such as data scraping, or mass-creating new accounts at some service online.
In response to a report about the data exposure from KrebsOnSecurity, Microleaves said it was grateful for being notified about a “very serious issue regarding our customer information.”
Abhishek Gupta is the PR and marketing manager for Microleaves, which he said in the process of being rebranded to “Shifter.io.” Gupta said the report qualified as a “medium” severity security issue in Shifter’s brand new bug bounty program (the site makes no mention of a bug bounty), which he said offers up to $2,000 for reporting data exposure issues like the one they just fixed. KrebsOnSecurity declined the offer and requested that Shifter donate the amount to the Electronic Frontier Foundation (EFF), a digital rights group.
From its inception nearly a decade ago, Microleaves has claimed to lease between 20-30 million IPs via its service at any time. Riley Kilmer, co-founder of the proxy-tracking service Spur.us, said that 20-30 million number might be accurate for Shifter if measured across a six-month time frame. Currently, Spur is tracking roughly a quarter-million proxies associated with Microleaves/Shifter each day, with a high rate of churn in IPs.
Early on, this rather large volume of IP addresses led many to speculate that Microleaves was just a botnet which was being resold as a commercial proxy service.
The very first discussion thread started by the new user Microleaves on the forum BlackHatWorld in 2013 sought forum members who could help test and grow the proxy network. At the time, the Microleaves user said their proxy network had 150,000 IPs globally, and was growing quickly.
One of BlackHatWorld’s moderators asked the administrator of the forum to review the Microleaves post.
“User states has 150k proxies,” the forum skeptic wrote. “No seller on BHW has 150k working daily proxies none of us do. Which hints at a possible BOTNET. That’s the only way you will get 150k.”
Microleaves has long been classified by antivirus companies as adware or as a “potentially unwanted program” (PUP), the euphemism that antivirus companies use to describe executable files that get installed with ambiguous consent at best, and are often part of a bundle of software tied to some “free” download. Security vendor Kaspersky flags the Microleaves family of software as a trojan horse program that commandeers the user’s Internet connection as a proxy without notifying the user.
“While working, these Trojans pose as Microsoft Windows Update,” Kaspersky wrote.
In a February 2014 post to BlackHatWorld, Microleaves announced that its sister service — reverseproxies[.]com — was now offering an “Auto CAPTCHA Solving Service,” which automates the solving of those squiggly and sometimes frustrating puzzles that many websites use to distinguish bots from real visitors. The CAPTCHA service was offered as an add-on to the Microleaves proxy service, and ranged in price from $20 for a 2-day trial to $320 for solving up to 80 captchas simultaneously.
“We break normal Recaptcha with 60-90% success rate, recaptcha with blobs 30% success, and 500+ other captcha,” Microleaves wrote. “As you know all success rate on recaptcha depends very much on good proxies that are fresh and not spammed!”
The exposed Microleaves user database shows that the first user created on the service — username “admin” — used the email address alex.iulian@aol.com. A search on that email address in Constella Intelligence, a service that tracks breached data, reveals it was used to create an account at the link shortening service bit.ly under the name Alexandru Florea, and the username “Acidut.” [Full disclosure: Constella is currently an advertiser on this website].
According to the cyber intelligence company Intel 471, a user named Acidut with the email address iulyan87_4u@gmail.com had an active presence on almost a dozen shadowy money-making and cybercrime forums from 2010 to 2017, including BlackHatWorld, Carder[.]pro, Hackforums, OpenSC, and CPAElites.
The user Microleaves (later “Shifter.io”) advertised on BlackHatWorld the sale of 31 million residential IPs for use as proxies, in late 2013. The same account continues to sell subscriptions to Shifter.io.
In a 2011 post on Hackforums, Acidut said they were building a botnet using an “exploit kit,” a set of browser exploits made to be stitched into hacked websites and foist malware on visitors. Acidut claimed their exploit kit was generating 3,000 to 5,000 new bots each day. OpenSC was hacked at one point, and its private messages show Acidut purchased a license from Exmanoize, the handle used by the creator of the Eleonore Exploit Kit.
By November 2013, Acidut was advertising the sale of “26 million SOCKS residential proxies.” In a March 2016 post to CPAElites, Acidut said they had a worthwhile offer for people involved in pay-per-install or “PPI” schemes, which match criminal gangs who pay for malware installs with enterprising hackers looking to sell access to compromised PCs and websites.
Because pay-per-install affiliate schemes rarely impose restrictions on how the software can be installed, such programs can be appealing for cybercriminals who already control large collections of hacked machines and/or compromised websites. Indeed, Acidut went a step further, adding that their program could be quietly and invisibly nested inside of other programs.
“For those of you who are doing PPI I have a global offer that you can bundle to your installer,” Acidut wrote. “I am looking for many installs for an app that will generate website visits. The installer has a silence version which you can use inside your installer. I am looking to buy as many daily installs as possible worldwide, except China.”
Asked about the source of their proxies in 2014, the Microleaves user responded that it was “something related to a PPI network. I can’t say more and I won’t get into details.”
Acidut authored a similar message on the forum BlackHatWorld in 2013, where they encouraged users to contact them on Skype at the username “nevo.julian.” That same Skype contact address was listed prominently on the Microleaves homepage up until about a week ago when KrebsOnSecurity first reached out to the company.
There is a Facebook profile for an Alexandru Iulian Florea from Constanta, Romania, whose username on the social media network is Acidut. Prior to KrebsOnSecurity alerting Shifter of its data breach, the Acidut profile page associated Florea with the websites microleaves.com, shrooms.io, leftclick[.]io, and online[.]io. Mr. Florea did not respond to multiple requests for comment, and his Facebook page no longer mentions these domains.
Leftclick and online[.]io emerged as subsidiaries of Microleaves between 2017 and 2018. According to a help wanted ad posted in 2018 for a developer position at online[.]io, the company’s services were brazenly pitched to investors as “a cybersecurity and privacy tool kit, offering extensive protection using advanced adblocking, anti-tracking systems, malware protection, and revolutionary VPN access based on residential IPs.”
A teaser from Irish Tech News.
“Online[.]io is developing the first fully decentralized peer-to-peer networking technology and revolutionizing the browsing experience by making it faster, ad free, more reliable, secure and non-trackable, thus freeing the Internet from annoying ads, malware, and trackers,” reads the rest of that help wanted ad.
Microleaves CEO Alexandru Florea gave an “interview” to the website Irishtechnews.ie in 2018, in which he explained how Online[.]io (OIO) was going to upend the online advertising and security industries with its initial coin offering (ICO). The word interview is in air quotes because the following statements by Florea deserved some serious pushback by the interviewer.
“Online[.]io solution, developed using the Ethereum blockchain, aims at disrupting the digital advertising market valued at more than $1 trillion USD,” Alexandru enthused. “By staking OIO tokens and implementing our solution, the website operators will be able to access a new non-invasive revenue stream, which capitalizes on time spent by users online.”
“At the same time, internet users who stake OIO tokens will have the opportunity to monetize on the time spent online by themselves and their peers on the World Wide Web,” he continued. “The time spent by users online will lead to ICE tokens being mined, which in turn can be used in the dedicated merchant system or traded on exchanges and consequently changed to fiat.”
Translation: If you install our proxy bot/CAPTCHA-solver/ad software on your computer — or as an exploit kit on your website — we’ll make millions hijacking ads and you will be rewarded with heaps of soon-to-be-worthless shitcoin. Oh, and all your security woes will disappear, too.
It’s unclear how many Internet users and websites willingly agreed to get bombarded with Online[.]io’s annoying ads and search hijackers — and to have their PC turned into a proxy or CAPTCHA-solving zombie for others. But that is exactly what multiple security companies said happened when users encountered online[.]io, which operated using the Microsoft Windows process name of “online-guardian.exe.”
Incredibly, Crunchbase says Online[.]io raised $6 million in funding for an initial coin offering in 2018, based on the plainly ludicrous claims made above. Since then, however, online[.]io seems to have gone…offline, for good.
Until this week, Shifter.io’s website also exposed information about its customer base and most active users, as well as how much money each client has paid over the lifetime of their subscription. The data indicates Shifter has earned more than $11.7 million in direct payments, although it’s unclear how far back in time those payment records go, or how complete they are.
The bulk of Shifter customers who spent more than $100,000 at the proxy service appear to be digital advertising companies, including some located in the United States. None of the several Shifter customers approached by KrebsOnSecurity agreed to be interviewed.
Shifter’s Gupta said he’d been with the company for three years, since the new owner took over the company and made the rebrand to Shifter.
“The company has been on the market for a long time, but operated under a different brand called Microleaves, until new ownership and management took over the company started a reorganization process that is still on-going,” Gupta said. “We are fully transparent. Mostly [our customers] work in the data scraping niche, this is why we actually developed more products in this zone and made a big shift towards APIs and integrated solutions in the past year.”
Ah yes, the same APIs and integrated solutions that were found exposed to the Internet and leaking all of Shifter’s customer information.
Gupta said the original founder of Microleaves was a man from India, who later sold the business to Florea. According to Gupta, the Romanian entrepreneur had multiple issues in trying to run the company, and then sold it three years ago to the current owner — Super Tech Ventures, a private equity company based in Taiwan.
“Our CEO is Wang Wei, he has been with the company since 3 years ago,” Gupta said. “Mr. Florea left the company two years ago after ending this transition period.”
Google and other search engines seem to know nothing about a Super Tech Ventures based in Taiwan. Incredibly, Shifter’s own PR person claimed that he, too, was in the dark on this subject.
“I would love to help, but I really don’t know much about the mother company,” Gupta said, essentially walking back his “fully transparent” statement. “I know they are a branch of the bigger group of asian investment firms focused on private equity in multiple industries.”
Adware and proxy software are often bundled together with “free” software utilities online, or with popular software titles that have been pirated and quietly fused with installers tied to various PPI affiliate schemes.
But just as often, these intrusive programs will include some type of notice — even if installed as part of a software bundle — that many users simply do not read and click “Next” to get on with installing whatever software they’re seeking to use. In these cases, selecting the “basic” or “default” settings while installing usually hides any per-program installation prompts, and assumes you agree to all of the bundled programs being installed. It’s always best to opt for the “custom” installation mode, which can give you a better idea of what is actually being installed, and can let you control certain aspects of the installation.
Either way, it’s best to start with the assumption that if a software or service online is “free,” that there is likely some component involved that allows the provider of that service to monetize your activity. As KrebsOnSecurity noted at the conclusion of last week’s story on a China-based proxy service called 911, the rule of thumb for transacting online is that if you’re not the paying customer, then you and/or your devices are probably the product that’s being sold to others.

Microsoft today released updates to fix a record 141 security vulnerabilities in its Windows operating systems and related software. Once again, Microsoft is patching a zero-day vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows. Redmond also addressed multiple flaws in Exchange Server — including one that was disclosed publicly prior to today — and it is urging organizations that use Exchange for email to update as soon as possible and to enable additional protections.
In June, Microsoft patched a vulnerability in MSDT dubbed “Follina” that had been used in active attacks for at least three months prior. This latest MSDT bug — CVE-2022-34713 — is a remote code execution flaw that requires convincing a target to open a booby-trapped file, such as an Office document. Microsoft this month also issued a different patch for another MSDT flaw, tagged as CVE-2022-35743.
The publicly disclosed Exchange flaw is CVE-2022-30134, which is an information disclosure weakness. Microsoft also released fixes for three other Exchange flaws that rated a “critical” label, meaning they could be exploited remotely to compromise the system and with no help from users. Microsoft says addressing some of the Exchange vulnerabilities fixed this month requires administrators to enable Windows Extended protection on Exchange Servers. See Microsoft’s blog post on the Exchange Server updates for more details.
“If your organization runs local exchange servers, this trio of CVEs warrant an urgent patch,” said Kevin Breen, director of cyber threat research for Immerse Labs. “Exchanges can be treasure troves of information, making them valuable targets for attackers. With CVE-2022-24477, for example, an attacker can gain initial access to a user’s host and could take over the mailboxes for all exchange users, sending and reading emails and documents. For attackers focused on Business Email Compromise this kind of vulnerability can be extremely damaging.”
The other two critical Exchange bugs are tracked as CVE-2022-24516 and CVE-2022-21980. It’s difficult to believe it’s only been a little more than a year since malicious hackers worldwide pounced in a bevy of zero-day Exchange vulnerabilities to remotely compromise the email systems for hundreds of thousands of organizations running Exchange Server locally for email. That lingering catastrophe is reminder enough that critical Exchange bugs deserve immediate attention.
The SANS Internet Storm Center‘s rundown on Patch Tuesday warns that a critical remote code execution bug in the Windows Point-to-Point Protocol (CVE-2022-30133) could become “wormable” — a threat capable of spreading across a network without any user interaction.
“Another critical vulnerability worth mentioning is an elevation of privilege affecting Active Directory Domain Services (CVE-2022-34691),” SANS wrote. “According to the advisory, ‘An authenticated user could manipulate attributes on computer accounts they own or manage, and acquire a certificate from Active Directory Certificate Services that would allow elevation of privilege to System.’ A system is vulnerable only if Active Directory Certificate Services is running on the domain. The CVSS for this vulnerability is 8.8.”
Breen highlighted a set of four vulnerabilities in Visual Studio that earned Microsoft’s less-dire “important” rating but that nevertheless could be vitally important for the security of developer systems.
“Developers are empowered with access to API keys and deployment pipelines that, if compromised, could be significantly damaging to organizations,” he said. “So it’s no surprise they are often targeted by more advanced attackers. Patches for their tools should not be overlooked. We’re seeing a continued trend of supply-chain compromise too, making it vital that we ensure developers, and their tools, are kept up-to-date with the same rigor we apply to standard updates.”
Greg Wiseman, product manager at Rapid7, pointed to an interesting bug Microsoft patched in Windows Hello, the biometric authentication mechanism for Windows 10. Microsoft notes that the successful exploitation of the weakness requires physical access to the target device, but would allow an attacker to bypass a facial recognition check.
Wiseman said despite the record number of vulnerability fixes from Redmond this month, the numbers are slightly less dire.
“20 CVEs affect their Chromium-based Edge browser and 34 affect Azure Site Recovery (up from 32 CVEs affecting that product last month),” Wiseman wrote. “As usual, OS-level updates will address a lot of these, but note that some extra configuration is required to fully protect Exchange Server this month.”
As it often does on Patch Tuesday, Adobe has also released security updates for many of its products, including Acrobat and Reader, Adobe Commerce and Magento Open Source. More details here.

Most every parent loves a new school year. Most likely because the beloved milestone offers us a clean slate and a chance to do things better, shape new habits, and close those digital safety gaps.
The hope that fuels change is a powerful thing. However, if you want to ensure your new habits stick, there’s some science you might consider. Psychologists suggest that to make a new change permanent, you should start with smaller, micro-size choices that will lead to sustainable patterns and habits. Micro habits allow you to take safe steps that are too small to fail but effective enough to generate long-term change.
Breaking down the task online safety into bite-sized pieces is a great approach for parents eager to put better habits into play this year. Establishing new ground rules doesn’t have to include restrictions, tantrums, or tears. You can start small, commit to work together, and build your new habits over time.
So often in this blog we offer a combination of practical digital tips proven to work such as robust password protocols, privacy settings, parental controls, smart phone protection, and social network/app safety.
Today, however, we will flip that approach and give you some foundations that will no doubt support and amplify your family’s daily online safety efforts. Ready? Here we go!
We’re all connected 24/7 but to what? Equipping kids to make wise decisions online begins with intentional, face-to-face connection at home with a parent or caregiver. When the parent-child relationship is strong, trust grows, and conversation flows. If and when a challenge arises, your child is more likely to turn to you.
Micro-habit: If your family doesn’t eat dinner together, start with one night a week (stay consistent with the day). Make the dinner table a no-phone zone and spend that time together listening and connecting. Build from there.
The new school year is a chance to get more involved with your child’s day-to-day communities (on and offline), including their teachers, friend groups, or hobbies. If you’ve been on the sidelines in the past, taking a few steps into their world can give you an exceptional understanding of their online life. Knowing where they go and who they know online has never been more critical, as outlined in our recent Connected Family Report.
Micro-habit: Does your child have a favorite app? Download it, look around, and understand the culture.
Summer—coupled with extra time online (often unmonitored)—can wreak havoc on a child’s sleep patterns, which, in turn, wreaks havoc on a family. If you have a tween or teen, ensuring they get the required hours of sleep is a significant way to keep them safe online. Think about it. Fatigue can impair judgment, increase anxiety, impact grades, and magnify moodiness, putting a child’s physical and emotional wellbeing at risk online and off.
Micro-habit: Think about setting a phone curfew that everyone agrees on. Giving your child input into the curfew makes it less of a restriction and more of a health or lifestyle shift. Remember, your child’s device is their lifeline to their peers so cutting them off isn’t a long-term solution.
With kids spending so much time on apps like TikTok, Instagram, Snapchat, and YouTube, those platforms inevitably influence your child more than just about anyone. Be on the lookout for behavior changes in your child that may be connected to digital risks such as cyberbullying, sextortion, gaming addiction, inappropriate content, or connecting with strangers.
Micro-habit: Consider setting time limits that allow your child to enjoy their online hangouts without being consumed or overly influenced by the wrong voices. Apply limits in small blocks at first and grow from there.
Balancing your online life with face-to-face activities and relationships is a must for your child’s physical and emotional wellbeing. But sometimes, striving for that balance can feel overwhelming. Being too stringent can cause big plans to collapse, sending our behaviors in the opposite direction. Balance requires constant re-calibration and pausing to take those small bites.
Micro-habit: Commit to one family outdoor activity together a month. Take a hike, learn to fish, take up tennis. Make the outings phone-free zones. Be consistent with your monthly micro-habit and build from there.
It’s been proven that any change you attempt to make ignites a degree of friction. And prolonged friction can discourage your efforts to stick to new habits. Ignore that noise and keep moving forward. Stay the course parents because this is the year your best intentions take shape.

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.
