Package name impersonates chai-as-promised, and the README is a copy of pino's documentation, but the actual code is a remote-code-execution dropper.

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-tokenized@7.2.3. - Avoid installing chai-as-tokenized@7.2.3. 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% Package name impersonates chai-as-promised, and the README is a copy of pino's documentation, but the actual code is a remote-code-execution dropper. The exported middleware (advertised as \`chai.use(chaiAsTokenized)\`) spawns lib/initializeCaller.js as a detached \`node\` child with \`stdio:'ignore'\` and \`child.unref()\`, hiding output and surviving parent exit. The child shadows the \`process\` global with a fake object whose env values are base64 strings, atob-decodes them to obtain \`https://amethyst-lorrin-26.tiiny.site/index.json\` and the header \`x-secret-key: \_\`, fetches JSON from that anonymous tiiny.site endpoint, and passes the response's \`cookie\` field to \`new Function.constructor('require', response)\` invoked with the live \`require\` — granting the remote, attacker-controlled host arbitrary code execution inside the consuming process with full module access. Combined signals: name-impersonation of a popular chai plugin, README mismatch with shipped code, base64-obfuscated C2 URL, anonymous static-file host (not a publisher domain), detached-and-silenced child spawn, and remote response evaluated as JavaScript. \#\# Source: ghsa-malware (fe8e4af381c4b8eb3ff6a93cbd50f27cd0196c86038024c04ad803780f72cae9) 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-as-tokenized - **Ecosystem:** npm - **Version:** 7.2.3 - **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:** 7.2.3 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [ADVISORY]()
