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:** 1.0.3 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-14255 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-2026-14255 confirms this npm version as malicious. Package name mimics the widely used \`secp256k1\` cryptography library but contains no cryptographic functionality. The declared \`main\` (\`index.js\`) is a single 33KB obfuscator.io-packed bundle whose only readable tokens are \`require(\` and \`axios\`; all strings — including target hostnames, URLs, and function names — are hex-escaped entries in the \`\_0x4058\` string array that are reconstructed at runtime... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-08-19T05:02:23.792Z - **Finished:** 2026-08-19T05:05:05.005Z - **Download time:** 252 ms - **Static scan time:** 25 ms - **AI review time:** 160936 ms - **Total time:** 161213 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 the exported connect() sends caller-supplied data in a GET path to an obfuscated remote base URL. No install-time or import-time trigger was found. - **Trigger:** Consumer explicitly invokes the exported connect() function. - **Impact:** Caller input may be disclosed to an undisclosed endpoint. - **Evidence paths:** package.json, README.md, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-19T05:05:05.005Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated outbound HTTP GET via axios. - **Rationale:** The concealed outbound request and unrelated package documentation create unresolved security risk, but the source does not establish automatic theft or another concrete malicious chain. - **Files touched:** index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for AI warning decision:** index.js is deliberately obfuscated., index.js imports axios and builds a hidden API\_BASE\_URL., Exported connect() performs an axios GET to that URL plus caller input., README.md references a different package: evm\_account. - **Evidence against:** package.json has no lifecycle hooks., Network call is only in exported connect(), not import-time., No source evidence of env/file harvesting, shell execution, or persistence. ## Affected versions and remediation This report applies to secp256k1-lib@1.0.3. - Avoid installing secp256k1-lib@1.0.3. 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.
