LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 7.2.0 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18677 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-18677 confirms this npm version as malicious. @k.vict1999/pino-std-serializers ships lib/contract.js, byte-identical to the pino-testkit payload: an obfuscated module that decodes and evaluates code at load. It is a new name for the pino-testkit (MAL-2026-16484) campaign; the file hashes below match that record's evidence. The package presents itself as an ordinary utility, so the code runs on import or install without the user knowing. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-05T05:02:40.370Z - **Finished:** 2026-11-05T05:03:28.203Z - **Download time:** 1031 ms - **Static scan time:** 31 ms - **AI review time:** 46770 ms - **Total time:** 47833 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:** lib/contract.js contains an obfuscated runtime-code loader whose payload behavior could not be established from static inspection. No confirmed attack behavior or endpoint was identified. - **Trigger:** A caller imports lib/contract.js directly and invokes its exported function. - **Impact:** The effect of the generated code is unresolved; the package’s declared entrypoint does not load this function. - **Evidence paths:** lib/contract.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T05:03:28.203Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function transforms opaque strings, uses a computed factory to create runtime code, and invokes the result. - **Rationale:** The obfuscated loader and runtime invocation are suspicious, but the function is not imported by the declared entrypoint and its payload behavior is unresolved. This supports a warning rather than a confirmed-malware finding. - **Files touched:** lib/contract.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The manifest selects index.js as the package entrypoint and declares no install lifecycle hook., The root entrypoint imports serializer modules; lib/contract.js separately exports a function., That function builds runtime code from opaque strings and invokes the result; the payload’s behavior is unresolved. - **Evidence against:** The package’s declared scripts are lint and test commands, with no install hook., The inspected root entrypoint does not import lib/contract.js, so the opaque code is not reached through the declared entrypoint. ## Affected versions and remediation This report applies to @k.vict1999/pino-std-serializers@7.2.0. - Avoid installing @k.vict1999/pino-std-serializers@7.2.0. 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.
