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:** 1.0.2 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-10607 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-2026-10607 confirms this npm version as malicious. The package masquerades as a chai plugin but ships the pino logger source tree plus an additional payload file lib/initializeCaller.js. That file is a top-level IIFE that base64-decodes a hardcoded URL stored under a fake process.env.DEV\_API\_KEY literal (decoding to https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df), POSTs the entire process.env of the loading process to that endpoint via axios, then... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-07-14T19:14:08.999Z - **Finished:** 2026-07-14T19:15:06.505Z - **Download time:** 252 ms - **Static scan time:** 70 ms - **AI review time:** 57184 ms - **Total time:** 57506 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:** An unreferenced initializer is a staged remote-code payload carrier. If directly imported, it contacts a remote endpoint and executes returned JavaScript locally. - **Trigger:** A consumer or another package explicitly loads \`lib/initializeCaller.js\`. - **Impact:** Arbitrary code execution in the importing process. - **Evidence paths:** lib/initializeCaller.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-14T19:15:06.505Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** HTTP fetch followed by \`new Function\` execution of server-controlled code. - **Rationale:** The package contains a concrete remote-code execution primitive, but static source inspection shows no lifecycle hook or reachable import path activating it. Flag as a staged payload carrier rather than block for an active install-time attack. - **Files touched:** lib/initializeCaller.js, package.json - **Network endpoints:** https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df ### Review decision - **Verdict:** Suspicious - **Confidence:** 98.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** \`lib/initializeCaller.js\` immediately posts to a Base64-obscured endpoint., It passes the response body to \`new Function\` and executes it with \`require\`., The initializer is not package-aligned with the claimed logger sources. - **Evidence against:** \`package.json\` contains no preinstall, install, or postinstall hook., No package source imports or requires \`lib/initializeCaller.js\`., \`package.json\` main \`index.js\` is absent, so normal package import cannot reach it. ## Affected versions and remediation This report applies to chai-as-act@1.0.2. - Avoid installing chai-as-act@1.0.2. 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.
