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.

Any consumer that imports chaikit runs this opaque code in their process. The advertised middleware in index.js is a trivial next() passthrough, so the obfuscated blob is the only substantive behavior of the package. package.json bundles axios as a runtime dependency, giving the opaque code a network egress channel. The README impersonates the pino logger (pino badges, pinojs/pino links, chai/chai-kit usage snippet), while the package.json description is unrelated boilerplate ('management of vulnerabilities') and file.js references a nonexistent./pino module — cover-story metadata consistent with a package published to be resolved by developers searching for chai or pino tooling. The combination of import-time execution of a large opaque blob, a mismatched cover story, and a bundled HTTP client is the canonical loader shape of an installer-harm supply-chain payload.\n\nAny 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.
