Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Calling runOperation can erase all files and directories at the supplied directory or current working directory. A remote endpoint authorizes the erasure. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-09T23:58:47.310Z - **Finished:** 2026-09-09T23:59:23.894Z - **Download time:** 515 ms - **Static scan time:** 23 ms - **AI review time:** 36046 ms - **Total time:** 36584 ms The recorded confidence comes from the underlying analysis.

A remote endpoint authorizes the erasure. - **Trigger:** A consumer imports the package and calls runOperation. - **Impact:** Destruction of an entire project directory, including source, configuration, and dependencies. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-09T23:59:23.894Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-gated recursive deletion of every target-directory entry. - **Attack narrative:** The exported function resolves a caller-controlled directory, contacts a remote authorization endpoint, then iterates over every entry in that directory and recursively removes directories or unlinks files. It only excludes index.js when that file happens to be directly inside the chosen root. This behavior is materially broader than cache cleanup and lets the remote service decide when destructive behavior activates. - **Rationale:** This is a destructive payload disguised as cache cleanup: it removes arbitrary project contents after remote authorization. The absence of an install hook limits automatic execution but does not make the exported behavior safe. - **Files touched:** \/\* - **Network endpoints:** https://testback-2aqe.onrender.com/can-cleanup ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The exported operation deletes every entry in its resolved target directory recursively, not selected cache or build artifacts., A remote service controls whether the destructive operation proceeds., The package describes itself as safe cache cleanup, which conflicts with wholesale project-directory deletion. - **Evidence against:** There are no npm lifecycle scripts, so installation does not invoke the code., Destruction requires a consumer to import and call runOperation. ## Affected versions and remediation This report applies to cache-cleanup-module@2.5.0. - Avoid installing cache-cleanup-module@2.5.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
