Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to chain-chai-test@1.3.5. - Avoid installing chain-chai-test@1.3.5. 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. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% chain-chai-test@1.3.5 advertises itself as a pino-style logger (keywords fast/logger/stream/json, exported alias module.exports.pino = middleware, pino-pretty visual assets) but the exported middleware factory spawns a detached \`node lib/caller.js\` process. caller.js performs \`axios.get\` against https://jsonkeeper.com/b/EXSIF (with a base64-obfuscated sibling URL https://jsonkeeper.com/b/ZK45J in lib/const.js, decoded from \`aHR0cHM6Ly9qc29ua2VlcGVyLmNvbS9iL1pLNDVK\`), reads \`.data.cookie\` from the response, and passes that string to \`new Function.constructor("require", s)\` invoked with the host process's \`require\`. That executes attacker-controlled JavaScript with full Node.js privileges in the consuming application. The fetch destination is an anonymous, mutable JSON-paste host, the URL is duplicated in obfuscated form to conceal the C2 endpoint, and the package name and exported API impersonate the legitimate pino logger to lure installers. Unrelated dependencies (request, sqlite3, parse-json) further indicate this is not a logger implementation. \#\# Source: ghsa-malware (763b4853da8c66a8801a7e33d815b99195a72b2343cc4d70a54b9eaa44108e90) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** chain-chai-test - **Ecosystem:** npm - **Version:** 1.3.5 - **Version published:** 2026-06-02T15:46:44.788Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 1.3.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [ADVISORY]() - [WEB]()
