Threat actors have already compromised over 270 Zimbra instances in remote code execution attacks targeting a high-severity Zimbra Collaboration Suite (ZCS) vulnerability. The ZCS email and collaboration suite is used by hundreds of millions of people and organizations, including thousands of businesses and hundreds of government agencies worldwide. Synacor patched the security flaw (tracked as CVE-2026-73570), which allows unauthenticated attackers to gain code execution remotely by exploiting a command injection weakness in the SNMP monitoring component when SNMP notifications are enabled, with the release of ZCS version 10.1.20 on July 20. CERT Polska, the Polish Computer Emergency Response Team (CERT), first flagged the vulnerability as targeted in the wild last Monday, when it also warned security teams to check their logs for suspicious activity, including the Zimbra service restarting unexpectedly, and for files created in the /opt/zimbra/jetty/webapps/, /opt/zimbra/jetty_base/webapps/, and /tmp/ folders by user zimbra over the last 30 days.

Oasis Security has disclosed a weakness in NVIDIA NemoClaw that could let an attacker-controlled webpage take unauthenticated control of the local Ollama instance serving an AI agent and plant hidden instructions inside the model itself. The findings were shared with The Hacker News ahead of publication, and the report says Oasis Security reported them to NVIDIA's Product Security Incident
Cybersecurity researchers have disclosed details of a new campaign that uses a cluster of 24 npm packages as free phishing infrastructure for redirecting to ClickFix-style fake CAPTCHA pages. "While the malware is simply a single HTML page inside the npm package, and while downloading it wouldn't do harm, the threat actor’s use of npm isn't to infect developers who install it, but to use the
Vulnerability management has been a staple of security programs since the dawn of the cybersecurity discipline. The symbiotic relationship between vulnerability and patch management teams has also existed for that time and has gone through waves of contention and thankfulness. While this relationship required thoughtful care and feeding from both sides, both sides were aiming to work toward a
A fake 113GB GTA VI build is packed with malware, using massive empty files to hide a tiny malicious payload. GTA VI hype has reached the point where people are volunteering to infect their own computers just to check if a leak is real. Someone on X asked their followers to “take one for the team” and test a 113GB file claiming to be a playable Grand Theft Auto VI build, according to Tom’s Hardware’s reporting. Someone did, and the results were exactly what you’d expect. A user that goes online with the handler @Aidas29506493 analyzed the file and found that it was completely fake and contained malware. Almost all of its 113GB consisted of empty data, with a tiny malicious payload hidden inside. did some reverse engineering. it is fully fake and full of viruses pic.twitter.com/An6VnSNTkd — Aidas (@Aidas29506493) August 22, 2026 “The decompiled bytecode literally contains commands to whitelist the entire C:\ drive in Windows Defender (powershell Add-MpPreference -ExclusionPath %SystemDrive%\) and kill security software (taskkill -f),” The researcher added in a post on X. They also added in another response, “It’s not 100 GB of actual code—it’s just a tiny 50 KB virus padded with 99.99% empty junk (literally endless zeroes).” It’s not 100 GB of actual code—it’s just a tiny 50 KB virus padded with 99.99% empty junk (literally endless zeroes). — Aidas (@Aidas29506493) August 22, 2026 The malware became obvious when researchers examined its code. It included commands to exclude the entire C: drive from Windows Defender and shut down other security software. Anyone who ran it could effectively disable their antivirus before the malware launched its next stage. This was not an accidental side effect, it was a deliberate step to prepare the system for further attacks. This particular fake didn’t appear in a vacuum. According to to the website IGN, that fake GTA 6 downloads have flooded piracy and torrent sites throughout the recent leak wave, riding genuine momentum from a leaker going by CyberLeek, who’s been releasing real gameplay clips and map footage in protest of Rockstar’s digital pre-order plans. That real leak activity is exactly what makes the fake downloads believable, since fans searching for CyberLeek’s actual content are primed to trust whatever else shows up alongside it. Every time GTA 6 appears in the news because of leaked footage, people quickly share it across Discord, mirror sites and other platforms. This creates the perfect conditions to trick users with fake downloads and phishing pages. With real and fake content mixed together, it becomes harder for users to tell what is safe. The scams go beyond huge fake game files. Researchers have found fake GTA 6 websites offering Windows installers that use DLL side-loading to run malware. They also found a fake “GTA 6 Mobile” app that redirects users to a domain linked to infostealers and ransomware. Other fake Rockstar Social Club login pages try to steal users’ account credentials. None of this should be surprising given the numbers involved. Kaspersky separately documented over 19 million attempted downloads of malware disguised as popular game titles across a single year, with GTA, Minecraft, and Call of Duty topping the list of abused brands specifically because of their large, dedicated communities. Big anticipated titles are a magnet for this stuff regardless of whether there’s an active leak cycle happening, and GTA VI right now has both the hype and the leak chaos simultaneously. There is no legitimate playable build of GTA VI circulating anywhere, full stop. The game launches November 19 on consoles, with a PC version to follow, and the only responsible move for anyone tempted by a torrent claiming otherwise is to close the tab. If the file looks too good to be true and it’s a hundred gigabytes of an unreleased AAA game showing up on a torrent site months early, it’s not a leak, it’s bait.

Microsoft is rolling out a new Teams meeting protection policy that allows administrators to automatically block all identified external bots from joining Teams meetings. This new feature builds on another Teams policy introduced in June that added smarter bot protection, ensuring all detected bots are tagged in the lobby and require organizer approval before joining. The new policy goes one step further and will automatically prevent external bots from joining Teams meetings, without requiring explicit organizer confirmation before they're admitted. "With this update, organizations can strengthen meeting security by configuring Teams policies to automatically block detected external meeting bots from joining meetings," the company said in a Microsoft 365 Message Center update on Friday. "This gives administrators additional control over how identified bots are handled and can help reduce organizational risk."
A breach at South Korea's government-backed startup platform exposed encrypted personal data after an encryption key was included in an API. Penta Security explains why encryption keys must be securely managed and kept separate from the data they protect.
Microsoft has confirmed that .NET Framework updates released as part of the August 2026 Patch Tuesday are breaking printing and PDF export in some applications. In a Windows release health alert seen by BleepingComputer, Microsoft says this known issue affects only apps that use the Windows Presentation Foundation (WPF) UI framework, an open-source graphical subsystem for building Windows desktop client applications. "After installing the August 2026 .NET Framework cumulative update, some WPF applications may fail with a System.IO.FileFormatException when printing or generating PDF/XPS content that uses certain fonts, including Calibri," Microsoft says. The complete list of impacted platforms includes both Windows client releases (including the latest versions of Windows 10 and Windows 11) and Windows Server (from Windows Server 2012 up to Windows Server 2025).
