OpenSSF/OSV advisory MAL-2026-4513 confirms this npm version as malicious. Package name \`chai-as-tuned\` impersonates \`chai-as-promised\` and ships a README copy-pasted from the unrelated pino project (npm/CI badges point at pinojs/pino). The advertised middleware in \`index.js\` spawns \`lib/initializeCaller.js\` as a detached node process whenever the exported function is invoked... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **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-tuned@7.2.2. - Avoid installing chai-as-tuned@7.2.2. 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 \`chai-as-tuned\` impersonates \`chai-as-promised\` and ships a README copy-pasted from the unrelated pino project (npm/CI badges point at pinojs/pino). The advertised middleware in \`index.js\` spawns \`lib/initializeCaller.js\` as a detached node process whenever the exported function is invoked. That script constructs a fake local \`process\` object whose \`DEV\_API\_KEY\` is a base64 literal decoding to \`https://aqua-margit-84.tiiny.site/index.json\` (tiiny.site is an anonymous static-hosting service), GETs the JSON via axios, and passes the \`response.cookie\` field to \`new Function.constructor('require', response)(require)\` — executing attacker-controlled JavaScript with full Node privileges and access to the host's \`require\`. The combination of name-confusion, copied README, base64-hidden C2 URL, \`Function.constructor\` indirection to defeat static review, and remote-fetch-and-eval is an unambiguous supply-chain attack: any consumer who follows the README and uses the main export will execute whatever code the attacker serves at runtime. \#\# Source: ghsa-malware (456afd075e2df98b9a07a876eb8b1e26cff0afe3f517d7b0f226f654e3e22bed) 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-tuned - **Ecosystem:** npm - **Version:** 7.2.2 - **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:** 7.2.2 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [ADVISORY]()
