OpenSSF/OSV advisory MAL-2026-2740 confirms this npm version as malicious. chai-as-type is a malicious npm package that when imported downloads a C2 dropper from https://api.npoint\[.\]io/c26313f0733957a7d787 and executes it (similar to malware in to chai-await-test). ## 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-type@7.0.5. The same advisory and Firewall decision cover these 2 recorded versions: 1.1.9, 7.0.5. - Avoid installing chai-as-type@7.0.5. 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-type is a malicious npm package that when imported downloads a C2 dropper from https://api.npoint\[.\]io/c26313f0733957a7d787 and executes it (similar to malware in to chai-await-test). --- \#\# Source: amazon-inspector (75650bd9993ad4d310c42309ea4f185f9ec2bca169073315a9a1604c76830e41) The package name impersonates the popular chai / chai-as-promised assertion libraries, but the code is an unrelated pino-shaped middleware whose only side effect is launching a remote-code loader. lib/caller.js issues an axios GET to https://jsonkeeper.com/b/XRGF3 (an anonymous public JSON paste host), takes the returned \`data.cookie\` string, constructs \`new Function.constructor('require', s)\`, and invokes it with the live \`require\` — executing arbitrary attacker-controlled JavaScript in the installer's Node process with full module access. The C2 URL is base64-encoded and stashed under fake \`DEV\_API\_KEY\` / \`DEV\_SECRET\_KEY\` keys on a locally redeclared \`process\` object (\`aHR0cHM6Ly9qc29ua2VlcGVyLmNvbS9iL1hSR0Yz\` decodes to the jsonkeeper URL); a sibling encoded URL \`.../b/4NAKK\` lives in lib/const.js. The loader is reached two ways: (1) when the exported \`pino\` middleware is invoked, index.js detaches a \`child\_process.spawn('node', \['lib/caller.js',...\])\`; (2) the package's \`smoke:pino\` npm script runs index.js directly. The paste-host content is mutable by the attacker at any time, so each fetch can deliver fresh payloads (credential theft, persistence, etc.) without re-publishing the package. ## 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-type - **Ecosystem:** npm - **Version:** 7.0.5 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 2 - **Latest version:** 7.0.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [REPORT]() - [PACKAGE]()
