The ShinyHunters extortion crew exploited an unpatched flaw in Oracle PeopleSoft to break into enterprise systems, steal data, and demand payment to keep it private. The campaign hit universities hardest. Google's Mandiant attributes it to the group it tracks as UNC6240, and dates the activity between May 27 and June 9. Oracle did not publish its advisory until June 10, so the bug was a zero-day the entire time. The flaw, CVE-2026-35273 , is a remote code execution bug in PeopleSoft Enterprise PeopleTools rated 9.8 out of 10. It needs no login and no user interaction, just network access over HTTP, to take over the server. If you run PeopleSoft with the Environment Management Hub reachable from outside, that is your exposure, and the immediate move is to lock those endpoints down. The vulnerability sits in the Updates Environment Management component, the piece behind the Environment Management Hub (PSEMHUB). Oracle lists PeopleTools 8.61 and 8.62 as affected and says earl...

Security researcher Chaotic Eclipse (aka Nightmare-Eclipse and MSNightmare) has released a new Windows BitLocker bypass dubbed GreatXML , a day after they published an exploit for Microsoft Defender. "This was an accidental discovery, it took a total of 4 hours to find this," the researcher said in a post on Blogger. "If you ever attempted to use Windows Defender Offline Scan, you're automatically vulnerable to a BitLocker bypass. I'm unsure if you can still trigger the bug without ever using the offline scan feature, because you can definitely." The exploit works as follows - Copy an XML file ("unattend.xml") and a recovery folder containing another XML file ("Recovery/WindowsRE/ReAgent.xml) to the root of the recovery partition. Reboot to Windows Recovery Environment ( WinRE ) by holding Shift while clicking Restart in the Windows power menu. If every step is followed correctly, the result is a shell spawned with unrestricte...

It's been one of those weeks. You expect the usual noise: recycled malware, sloppy attacks, another easy target getting hit. Instead, there's a supply chain attack kit in a public repo, a $5,000-a-month RAT that clones browsers, and research showing AI agents can be tricked into leaking real credentials. The bigger problem is how polished this all looks now. Mule networks run like SaaS. Deepfake KYC bypass is sold as a feature. Endpoint tools can be quietly weakened using built-in OS settings, with no exploit needed. Here's the full list of threats, tools, flaws, and updates worth knowing.

For thirty years, vulnerability management ran on a buffer: the months between when a vulnerability was found and when someone could figure out how to weaponize it. The solution was straightforward enough; triage by severity, schedule the fix, validate, and move on. The buffer was what made that work. Today, that buffer is gone. AI didn't make your team slower. It changed the other side of the equation, compressing discovery-to-exploit from months to hours . And the sad truth for defenders is that a process built for breathing room can't survive without it. AI Turned Vulnerability Discovery Into a Volume Game In its May 2026 update, Anthropic reported that it and approximately 50 partners used Claude Mythos Preview to find more than 10,000 high- or critical-severity vulnerabilities in systemically important software in a single month. Earlier figures were just as stark. Pointed at Firefox, the gated Mythos model wrote 181 working exploits , against just 2 from t...

Cybersecurity researchers have warned of a "resurgence and expansion" of JDY , a covert network associated with China-nexus state-sponsored threat actors. "The JDY botnet comprises over 1,500 SOHO [small office and home office] and IoT devices and operates as a centrally controlled, high-performance scanner used to discover, fingerprint, and continuously map exposed services at scale," Lumen's Black Lotus Labs said in a report shared with The Hacker News. JDY was first flagged as a cluster within another botnet codenamed KV-botnet in mid-December 2023. Primarily used for broader scanning against internet targets, the stealthy network comprising compromised SOHO routers, firewalls, and IoT devices has been put to use by Chinese hacking groups like Volt Typhoon. Following KV-botnet's takedown by the U.S. government in early 2024, the botnet operators began making behavioral changes to the network, with the second KV cluster largely going offline. It...
