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 chai-mocks@1.1.5. - Avoid installing chai-mocks@1.1.5. 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% The package masquerades as a pino-style logger middleware but is a remote code loader. When the exported middleware is invoked, index.js spawns a detached \`node./lib/caller.js\` child process. caller.js fetches https://jsonkeeper.com/b/U2BTS (with a second URL https://jsonkeeper.com/b/XRGF3 stored base64-encoded in a variable named DEV\_API\_KEY to disguise it as a configuration constant), reads the \`cookie\` field of the JSON response, and executes it via \`new Function.constructor('require', s)(require)\` — arbitrary attacker-controlled code execution with full Node \`require\` access on the consumer's machine. jsonkeeper.com is an anonymous, mutable paste service; the contents can be changed by the author at any time without republishing the package. The package name (\`chai-mocks\`) and bait API surface (exports \`pino\`, references DEFAULT\_LEVELS/redact/customLevels, scripts named \`smoke:pino\`) are unrelated to the package's author identity (Alexus111 \) and are designed to lure developers who mistype or confuse it with the chai or pino logger ecosystems. The base64-obfuscated URLs and fake \`DEV\_API\_KEY\`/\`DEV\_SECRET\_KEY\` variable names confirm intent to hide the C2 endpoint. \#\# Source: ghsa-malware (2110c382b534a2754972e66578b044823108410f3a656aad1616834d18bba322) 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:** chai-mocks - **Ecosystem:** npm - **Version:** 1.1.5 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 1.1.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [ADVISORY]() - [PACKAGE]()
