OpenSSF/OSV advisory MAL-2026-6497 confirms this npm version as malicious. chai-as-synced@7.0.9 impersonates the pino logger: it ships pino's README, LICENSE, docs/, index.d.ts and lib/ file layout (proto.js, levels.js, redaction.js, transport.js, worker.js, tools.js, multistream.js) with pino's keywords (\`fast\`,\`logger\`,\`stream\`,\`json\`), while package.json declares an unrelated name and author (Robert King \, bugs URL https://jsonspack.com/issues) and a boilerplate... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-08-24T17:05:04.876Z - **Finished:** 2026-08-24T17:05:04.876Z - **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-synced@7.0.9. The same advisory and Firewall decision cover these 2 recorded versions: 6.0.3, 7.0.9. - Avoid installing chai-as-synced@7.0.9. 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-synced@7.0.9 impersonates the pino logger: it ships pino's README, LICENSE, docs/, index.d.ts and lib/ file layout (proto.js, levels.js, redaction.js, transport.js, worker.js, tools.js, multistream.js) with pino's keywords (\`fast\`,\`logger\`,\`stream\`,\`json\`), while package.json declares an unrelated name and author (Robert King \, bugs URL https://jsonspack.com/issues) and a boilerplate description unrelated to logging. index.js unconditionally executes \`require('./lib/config')\` at module top level. lib/config.js is not pino's config module; it is a ~4MB single-line obfuscator.io bundle (rotated string array of ~23,868 entries, hex-escaped identifiers, control-flow flattening, nested decoder functions) that auto-runs the moment any consumer imports the package. The package also declares \`axios ^1.10.0\` as a runtime dependency although the visible wrapper (a no-op express middleware) has no HTTP use, positioning the hidden payload to perform network I/O at import. The combination of deceptive identity, hidden obfuscated payload, import-time auto-execution, and a bundled HTTP client is a covert-code-execution shape inconsistent with any legitimate logging library. ## 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-synced - **Ecosystem:** npm - **Version:** 7.0.9 - **Version published:** 2026-08-24T09:33:27.583Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-09-07T16:24:57.512Z - **Known versions:** 3 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]()
