Someone should tell the North Korean IT workers to stop using the Golden Gate bridge as their Zoom backgrounds.

👋 There's been a lot of discussion recently about the volume of vulnerability reports that PSIRTs, open-source maintainers, and technology producers are receiving. The CVE Program's Researcher Working Group (RWG), which I've been chairing for the last 9 months, is developing guidance for security researchers on how to most effectively report new vulnerabilities to supplier organizations.

👉 We're seeking input from the community on the data points, report characteristics, and reporting practices that help reduce time-to-verification for new vulnerabilities. If you're a researcher, a PSIRT, a VM or SecOps practitioner, or a bug bounty provider who's been on the hook for looking at or validating vulnerability reports in your career, we want your feedback on what works — and what doesn't!

🗓️ The discussion will stay open through (at least) June 5, 2026. Feedback is best submitted by commenting on the GitHub issue below!

Microsoft’s stance on zero day exploits is a dumpster fire of their own making

Nightmare Eclipse vs Microsoft risks turning into a wildfire of corporate protection over cyber defence.

Quantifying 2026 Routinely Targeted Vulnerabilities (So Far) | Blog | VulnCheck

VulnCheck identified 25 CVEs disclosed in 2026 that have been routinely targeted by adversaries and researchers so far this year, drawing from a global body of exploit code and exploitation data.

Not to brag but I purchased a ticket for a 2 hour flight to Chicago, but because of the weather it was a 3 hour flight, and the extra hour was free. 👍

❗Earlier today, VulnCheck Canaries detected first-time exploitation of CVE-2026-28515 and CVE-2026-28517 in openDCIM, an open-source code base used for data center infrastructure management.

🐚 The cluster of attacker activity we're observing so far originates from a single Chinese IP and uses what appears to be a customized implementation of AI vuln discovery tool Vulnhuntr to automatically check for vulnerable installations before dropping a PHP webshell.

🌐 The VulnCheck team's ASM queries for these vulnerabilities find fewer than 50 systems online, many of which belong to higher education institutions globally. Both CVEs were discovered by new VulnCheck research team member @chocapikk_.
