It's been such a tough October for AI Developer Platforms ... that two more disclosed incidents while we were writing up this blog: wiz.io/blog/black-october-fo…
Check it out for details on what we're seeing attacks do with compromised credentials from the recent incidents
Kudos to @github on moving the needle, but this vulnerability class isn't gone.
This quoted post is unavailable.
Isn't it silly to call every RCE vuln "smt2shell"? That's the definition of RCE pretty much - giving shell.

🫂"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 🤞
List of most popular/active public repos on GitHub - April edition:
- @openclaw hype is over?
- @Microsoft GenAI tutorials are back to the first place

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

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

Monthly list of most popular/active public repos on GitHub:
- @openclaw keeps the first place (although its half pace comparing to February)
- Rise of the personal claude skills and harnesses over official anthropics/skills
- karpathy/autoresearch - fast-breaker
Turns out # of forks is a great metric of repo popularity. Here is the most popular/forked repos of Feb 2026. Of course, #OpenClaw is leading the pack:

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-the-lon…
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).
Or extend their PAT revocation API to cover other token types: docs.github.com/en/rest/cred…

🪱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

Second part of our research on secret leaks In AI.
🤖 65% of Forbes AI 50 companies leaked secrets on GitHub. @sshaybbc revealed how AI speed without security = leaks waiting to happen.

Re- #Shai_Hulud attack - its disturbing to see the evolution of the attacker. Comparing to #s1ngularity attack, new elements added:
- Worm-able nature of the exploit
- Better automation of the secret scan
- Bundling of the secrets for exfiltration with tojson(secrets)
Shay Berkovich retweeted
More from me on s1ngularity, the Nx supply chain attack.
We @wiz_io took advantage of the break in attacker activity to break down:
* overall impact
* efficacy of the AI usage (not great!)
* TTPs and investigation breadcrumbs we've seen to date
* our work to notify victims
Shay Berkovich retweeted
😱Imagine waking up to see all your private github repositories were published publicly ...
That's what happened overnight for >400 users/orgs and >5000 repositories
s1ngularity (the Nx supply chain attack) continues to bear fruit for attackers.
Rotate ASAP!
