Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-10046/ (Markdown: https://insights.sbomify.com/MAL-2026-10046/index.md)","id":"MAL-2026-10046","markdown":"https://insights.sbomify.com/MAL-2026-10046/index.md","name":"MAL-2026-10046","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require, index.js spawns lib/initializeCaller.js as a detached background process. That script decodes a base64-hidden URL (https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df), POSTs the caller's full process.env to that endpoint via axios, and then passes the HTTP response body into `new Function('require', response.data)` and immediately invokes it with the real `require`, giving the remote server arbitrary code execution inside the installer's Node.js process. The C2 URL and headers are stored as base64 inside fake object literals labeled DEV_API_KEY/DEV_SECRET_KEY, and the package name and package.json keywords (fast, logger, stream, json) masquerade as a pino-style logger middleware to lure installers into requiring it. The combined behavior — environment-variable exfiltration to a hardcoded attacker endpoint plus remote-fetched code execution with full require access — compromises any machine that installs or imports this package, exposing tokens, cloud credentials, and CI secrets and enabling full follow-on RCE.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in chai-as-smart (npm)","id":"MAL-2026-10046","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"chai-as-smart","purl":"pkg:npm/chai-as-smart","source":"MAL-2026-10046"}],"products":null,"published":"2026-07-09","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-10046/"}
