🫂"hugs from TeamPCP." We're now 47 days and three rounds deep into the Checkmarx incident -- and this time TeamPCP left a message for victims in `~/hugs_from_teamPCP.txt` Things appear mitigated, but waiting to see if rotation was a bit more atomic this time 🤞

Preliminary exploit detections for Copy Fail (CVE-2026-31431) based on our tests (these work best in combination): 1. "NET: Registered PF_ALG protocol family" in kern.log & syslog 2. curl for "copy[.]fail/exp" (if attacker is lazy) 3. su record without invoking user in auth.log

Did somebody manage to use it as a container escape from a non-priv container?

Patch your Linux boxes! Copy.Fail is a trivially exploitable logic bug in Linux, reachable on all major distros released in the last 9 years. A small, portable python script gets root on all platforms. Found by the teams at @theori_io and @xint_official More

Fork commits keep showing up in supply chain attacks (tj-actions, reviewdog, TeamPCP). But, I keep seeing incorrect explanations in incident threads/blogs So I built a microsite to cut through the confusion 🔗in🧵

Another interesting point - the first non-AI repo is only 6th place.

@GrahamHelton3 This is great research @GrahamHelton3 . Couldn't find it in the blog - is the command execution possible with node/proxy:list or node/proxy:watch?

UPDATE: Shai-Hulud 2.0 has a long tail, and it may have led to $7M in crypto theft. Earlier today, our update laid out how sha1-hulud may have caused the Trust Wallet incident. Trust Wallet just announced the same conclusion 📷Read our analysis >> wiz.io/blog/snipping-…

With #shaihulud2 refuses to die with the long tale of infections (117 new compromised machines in the last 72 hours, most of them form @Cursor IDE), all @github has to do is disable the gho_ tokens of the super-spreaders (last 2 active spreaders are Cpreet and moh-abed).

🪱sharing more on sha1-hulud w/@sshaybbc * 2 packages == ~60% of infections * 400k unique secrets in truffleSecrets.jsons, only 2.5% verified, & the majority of those short lived JWTs for GitHub Actions! * 3/4 of impacted workloads were CI/CD, 1/4 were users 🔗below

@brankopetric00 I would advise to go with EKS pod identity rather than IRSA.

@adnanthekhan At the end we need an attribution to stop this crazy attack sequence, I'd love to see more publications around the actor behaviour and to see GH doing more.

@adnanthekhan No cloud impact so far, but the abuse of the cloud access is an incremental evolution step that this actor seems to demonstrate with every attack. Given the likely pool of cloud creds they have now I won't be surprised...
