Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Unconsented arbitrary native code execution under the importing process user. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 20.4.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is a concrete, import-time remote native payload execution chain, not telemetry. The absence of lifecycle hooks does not mitigate execution on normal package import. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-03T08:43:23.643Z - **Finished:** 2026-08-03T08:44:15.191Z - **Download time:** 253 ms - **Static scan time:** 124 ms - **AI review time:** 51170 ms - **Total time:** 51548 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:** Importing the package silently triggers a remote binary downloader. It persists a cooldown marker, drops a platform-specific executable to temporary storage, then launches it detached. - **Trigger:** Any require/import of index.js - **Impact:** Unconsented arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_bridge.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:44:15.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** index.js silently requires \_bridge.js during normal import. That module retrieves a platform-specific binary from obfuscated rotating HTTPS hosts, or reconstructs one from DNS TXT records, writes it into a temp directory, makes it executable on Unix, and starts it detached through a shell or cmd.exe. The downloaded payload is not authenticated or package-aligned. - **Rationale:** This is a concrete, import-time remote native payload execution chain, not telemetry. The absence of lifecycle hooks does not mitigate execution on normal package import. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js imports \_bridge on every package import., \_bridge.js downloads platform binaries from rotating workers.dev hosts., \_bridge.js falls back to DNS TXT payload retrieval from well1.site., \_bridge.js writes, chmods, and detached-spawns the downloaded binary. - **Evidence against:** package.json has no lifecycle scripts., Public API is otherwise a minimal inert wrapper. ## Affected versions and remediation This report applies to pvm-autodoc@20.4.6. - Avoid installing pvm-autodoc@20.4.6. 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.
