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-2026-18692 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-2026-18692 confirms this npm version as malicious. pino-std ships lib/contract.js, byte-identical to the pino-testkit payload: a copy of the pino logger with an extra 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:** 97.0% - **Started:** 2026-11-05T05:19:10.457Z - **Finished:** 2026-11-05T05:20:05.886Z - **Download time:** 516 ms - **Static scan time:** 34 ms - **AI review time:** 54878 ms - **Total time:** 55429 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 opaque loader that reconstructs and invokes generated code. It is outside the declared main entrypoint, and no package-file caller was found. - **Trigger:** A caller directly loads lib/contract.js and invokes its exported contract() function. - **Impact:** The hidden payload can execute when that function is called; its behavior remains unresolved. - **Evidence paths:** lib/contract.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T05:20:05.886Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function decodes obfuscated strings, constructs generated functions, and invokes the resulting code. - **Rationale:** The obfuscated dynamic-code loader is a real, separately callable payload carrier, but source inspection did not establish what its payload does or that the package's main entrypoint reaches it. This supports a warning for unresolved risk, not a confirmed attack. - **Files touched:** lib/contract.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** lib/contract.js contains an obfuscated string reconstruction path that creates generated code., Calling the generated function is reachable inside the separately exported contract() function., The loader's payload behavior is not resolved by static inspection. - **Evidence against:** package.json declares index.js as the main entrypoint and lists no install lifecycle script., index.js exports serializers and wrappers without importing lib/contract.js. ## Affected versions and remediation This report applies to pino-std@7.2.0. - Avoid installing pino-std@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.
