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-2026-11032/ (Markdown: https://insights.sbomify.com/MAL-2026-11032/index.md)","id":"MAL-2026-11032","markdown":"https://insights.sbomify.com/MAL-2026-11032/index.md","name":"MAL-2026-11032","record":{"aliases":["GHSA-vh7h-h87g-qv6x"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"chai-as-stringify@7.0.1 is a typosquat of chai-as-promised. The tarball ships lib/config/config.env, a ~4MB heavily obfuscated JavaScript payload using obfuscator.io-style transforms (string-array shuffler, hex `_0x...` identifiers, char-code lookup, control-flow flattening). The `.env` extension conceals the JS blob from scanners that only inspect `.js` files. The package's top-level index.js executes `require('./lib/config/config')`, which resolves to this staged blob and runs it whenever the module is loaded. The package's advertised purpose is unrelated cover: the README is plagiarized verbatim from pino (Transports, Low overhead, nearForm/Platformatic acknowledgments) while claiming to provide 'Chai assertions for testing Reddit API responses'; author metadata is a generic `james@abscond.org` with homepage `https://github.com/james`; CI badges point at the placeholder `github.com/yourusername/chai-as-stringify`; the visible exported API is a no-op middleware stub. The combination of a typosquat name, plagiarized/placeholder metadata, and a large obfuscated payload staged under a non-JS extension and auto-loaded on require is the smuggle-and-cover-story supply-chain attack shape.\n\nAny computer that has this package installed or running should be considered fully compromised.

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.","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-stringify (npm)","id":"MAL-2026-11032","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":["0"],"last_affected":[],"package":"chai-as-stringify","purl":"pkg:npm/chai-as-stringify","source":"MAL-2026-11032"}],"products":null,"published":"2026-07-23","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-2026-11032/"}
