We’ve been digging through the #React RCE mess for two days now, trying to get at least some visibility into what’s going on out there. None of this is easy to detect, and most signals vanish in memory before you can even look at them. My teammate @_swachchhanda_ put together a pair of #Sigma rules that cover the one thing that reliably shows up when someone actually executes code on a Node.js server -> child processes. One rule for Linux, one for Windows. It’s not a silver bullet, just one of the few angles that makes sense right now. We pushed all our #YARA and #Sigma signatures for the React RCE cases as well, and contributed the Sigma rules upstream: github.com/SigmaHQ/sigma/pul… This whole situation shows how much attack surface lives in places many of us didn’t think about before. I expect we’ll see more of this class of issues now that people realize what’s possible.

🎁 GenAI x Sec Advent 1 - Visual Threat Intelligence If you follow my work you know I am a big fan of visualization to explain complex or technical content. I used to spend days building the perfect infographic, but now I can generate one in a single shot thanks to LLM advancements. To show this I tested the Personal AI Infrastructure from @DanielMiessler. This a set of skills you can use with Claude Code and some skills are dedicated to visualization. If you are not familiar with Claude Skills, it is simply a way to give Claude task specific playbooks. In the examples below I took several threat reports and produced multiple visualization. With one wink you can upgrade your weekly threat briefing in the style you want.

The SHA1-Hulud npm mess keeps growing, so we added additional detections for it today - new YARA rules by my colleague @marius_benthin in our public signature-base - cover bun_environment.js / setup_bun.js and the malicious preinstall script variants from the Wiz / Aikido write-ups - already live in THOR Lite and THOR Cloud Lite Rules: github.com/Neo23x0/signature… THOR Lite: nextron-systems.com/thor-lit… THOR Cloud Lite: thorcloud-lite.nextron-syste… #SHA1Hulud #NPM #NPMWorm
We used to fight worms on the OS level. Slammer, Blaster, Conficker.. all that stuff Now we get the same behaviour one layer up - inside the software ecosystems we trust every day NPM tokens, transitive deps, weak account hygiene, zero visibility… and suddenly a self-propagating worm runs through the supply chain like it’s 2003 again This incident shows the real blind spot: package ecosystems aren’t <content> .. they’re execution surfaces. Nobody monitors them, nobody hardens them and attackers don’t even need an exploit to make them go wild #SHA1Hulud #NPM #NPMWorm linkedin.com/posts/advocatem…

GitLab’s Vulnerability Research team uncovered a widespread npm supply chain attack involving a destructive malware variant with a built-in “dead man’s switch.” The malware spreads through compromised npm packages, steals credentials, and contains a data-wiping payload if its channels are disrupted. We’re sharing early details to help developers and security teams assess exposure and stay protected. 👉 Read the full analysis: about.gitlab.com/blog/gitlab…
