The npm package 'chai-as-map' version 2.3.5 is identified as malicious. It masquerades as a chai-related utility but contains a large obfuscated payload executed at import time. The package bundles source code from the pino logger but exports only a no-op Express middleware. The obfuscated code includes a multi-megabyte hex string array with complex decoding, suggesting a stealer or loader functionality delivered via typosquatting and name confusion. The package also declares an unnecessary axios dependency, likely to reconstruct a remote destination at runtime. No CVSS score is available for this threat.
