chai-as-testkit @2.3.5

Summary

The package is published as 'chai-as-testkit' with a description referencing vulnerability management, but the tarball ships pino's README, docs/, index.d.ts, and lib/ tree (proto, levels, transport, worker, redaction) under an unrelated author (Robert King <hello@jsonspack.com>, bugs.url jsonspack.com) rather than the real pinojs publisher. The shipped index.js is a synthetic stub whose only effect is const config = require('./lib/config') , and lib/config.js is a 4,083,409-byte single-line obfuscator.io-style bundle: a rotated hex-escaped string array of ~23,953 entries with control-flow flattening and dead-code layers (webcrack inlines 40,105 decoded strings across the decoder layers before failing to serialize). This blob runs immediately when any consumer imports the package, executing attacker-controlled code inside the developer or CI Node.js process. The pino impersonation is the social-engineering wrapper around an on-import loader; the shape (name/description/author mismatch + hollow main entry that delegates to a multi-megabyte obfuscated module at require time) is a typosquat-delivered install/import-time RCE vehicle rather than a logging library.
