This is the first update to the TeamPCP supply chain campaign threat intelligence report, When the Security Scanner Became the Weapon (v3.0, March 25, 2026). That report covers the full campaign from the February 28 initial access through the March 24 LiteLLM PyPI compromise. This update covers developments since publication. Checkmarx ast-github-action: All 91 Tags Were Compromised, Not Just v2.3.28 The most significant new finding since the report s publication: the scope of the Checkmarx ast-github-action compromise was substantially larger than publicly reported. Checkmarx s official security advisory stated that all older versions have been permanently deleted but did not quantify how many tags were affected. This ambiguity allowed the security community to anchor on a single confirmed version (v2.3.28) as the extent of the compromise. Sysdig s analysis characterized it as Checkmarx/ast-github-action/2.3.28: (possibly more). Even Wiz, which assessed that it is likely all tags were impacted, only observed the single tag directly. An independent security researcher who was working this incident firsthand at a Checkmarx customer has now provided primary evidence that all 91 published tags were overwritten every version from v0.1-alpha through v2.3.32. The evidence is publicly visible in the GitHub activity log , which shows 91 tag deletions performed during Checkmarx s remediation between 19:09 and 19:16 UTC on March 23, 2026. Three of the malicious commits are still visible on GitHub: f1d2a3477e0d f58de2470825 aa52a82cddf2 Each malicious commit follows an identical pattern: the legitimate Docker-based action.yml was replaced with a composite action that executes a credential-stealing setup.sh before delegating to the legitimate Checkmarx action at pinned SHA 327efb5d . Each commit was individually crafted with a version-appropriate backdated timestamp and fake commit message (e.g., 2.0.30: PR # ). The attacker did not reuse a single malicious commit across multiple tags they created individual poisoned commits for individual versions. The impact of this under-reporting is material. Organizations that searched their CI/CD logs only for [email protected] would have missed compromised runs referencing any of the other 90 poisoned tags. The credential stealer executed regardless of which tag version was referenced. Recommended action: Search your CI/CD workflow logs for ANY reference to checkmarx/ast-github-action that executed between 12:58 and 19:16 UTC on March 23, 2026. If found, treat all secrets accessible to that workflow as compromised and rotate immediately. The only safe version is v2.3.33, released during remediation. For comparison, the companion kics-github-action received accurate all 35 tags reporting from the outset, largely because GitHub Issue #152 was filed publicly with the title Malware injected in all Git Tags. No equivalent public issue was filed for ast-github-action . CISA Adds CVE-2026-33634 to Known Exploited Vuln
