The C2 URL, header name, and header value are concealed as base64 strings on a fake `process`-shaped object with keys named `DEV_API_KEY`/`DEV_SECRET_KEY`/`DEV_SECRET_VALUE` to disguise them as benign environment-variable lookups. The README, npm badges, and exports (`module.exports.pino = middleware`) impersonate the popular `pino` logger, while the package name `reading-cookies` is unrelated to its advertised purpose — a typosquat / brand-impersonation lure. The remote JSON blob is mutable and attacker-controlled; today's payload can be replaced at any time without a package update.\n\n## Source: ghsa-malware (f4a194e55ab8a2e54ad6d9ce957abd157196a174cba472fdb8c3d54235b5920c)\nAny computer that has this package installed or running should be considered fully compromised.
