Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. OpenSSF/OSV advisory MAL-2026-16293 confirms this npm version as malicious. chai-as-indexed presents itself as a pino-compatible logger (package.json keywords fast/logger/stream/json, exports module.exports.pino, lib/\* filenames mirror pino) but the exported middleware's only real action is to spawn a detached Node child that runs lib/caller.js. lib/caller.js hides its C2 behind a fake local \`process.env\` object whose values are base64 literals (DEV\_API\_KEY, DEV\_SECRET\_KEY,... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-10-08T04:25:05.194Z - **Finished:** 2026-10-08T04:25:05.194Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. 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-as-indexed@6.0.5. - Avoid installing chai-as-indexed@6.0.5. 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% chai-as-indexed presents itself as a pino-compatible logger (package.json keywords fast/logger/stream/json, exports module.exports.pino, lib/\* filenames mirror pino) but the exported middleware's only real action is to spawn a detached Node child that runs lib/caller.js. lib/caller.js hides its C2 behind a fake local \`process.env\` object whose values are base64 literals (DEV\_API\_KEY, DEV\_SECRET\_KEY, DEV\_SECRET\_VALUE); at runtime they decode to the URL https://tomato-erminie-2.tiiny.site/index.json and a request header. The decoded URL is fetched and the JSON response's \`cookie\` field is passed to \`new Function.constructor('require', response)(require)\`, executing attacker-controlled JavaScript with the host process's full Node privileges and \`require\` handed in. The destination is an anonymous, author-mutable tiiny.site host with no pinning or integrity check. Any application that requires this package expecting pino and invokes the middleware will fetch and execute whatever the attacker is currently serving. ## 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-as-indexed - **Ecosystem:** npm - **Version:** 6.0.5 - **Version published:** 2026-10-07T14:17:19.544Z - **Package first seen:** 2026-09-26T01:43:16.919Z - **Package last seen:** 2026-10-08T04:25:05.194Z - **Known versions:** 2 - **Latest version:** 6.0.5 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]()
