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 delete all accessible top-level files and directories beneath the caller's current working directory. Deletion is remotely authorized by an external service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-11T05:39:58.419Z - **Finished:** 2026-09-11T05:40:35.679Z - **Download time:** 512 ms - **Static scan time:** 14 ms - **AI review time:** 36734 ms - **Total time:** 37260 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Calling runOperation can delete all accessible top-level files and directories beneath the caller's current working directory. Deletion is remotely authorized by an external service. - **Trigger:** A consumer imports the package and calls runOperation without a safe directory argument. - **Impact:** Irreversible loss of a consumer project's files and directories. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-11T05:40:35.679Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-gated recursive deletion of the working directory contents. - **Attack narrative:** A caller invoking runOperation defaults to its current working directory. The package contacts a remote endpoint and, if allowed, enumerates every top-level entry and recursively force-deletes directories or unlinks files. It does not restrict targets to caches or build artifacts, so a normal project directory can be wiped. There is no install hook, but the exported destructive capability is concrete and remotely gated. - **Rationale:** This is a remotely controlled, broad destructive operation disguised as cache cleanup. Its explicit invocation requirement reduces automatic exposure but does not make the behavior safe or package-aligned. - **Files touched:** index.js, process.cwd()/\* - **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 defaults to the caller's current working directory., It enumerates every top-level entry and recursively force-removes directories or unlinks files., A remote endpoint decides whether the destructive operation runs., The manifest presents a cleanup package, but the implementation has no path allowlist or cache-specific filtering. - **Evidence against:** There are no npm lifecycle scripts, so installation alone does not invoke the operation., The destructive function must be explicitly imported and called. ## Affected versions and remediation This report applies to cache-swipper@3.6.0. - Avoid installing cache-swipper@3.6.0. 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.
