The package has empty description and author fields and is published at version 99.9.5, a shape consistent with a dependency-confusion squat against a private/internal package name: installing (or accidentally resolving) this name causes a reconnaissance beacon to fire from the developer or CI machine, confirming code execution on the target and leaking host, user, cwd, and network identifiers to the attacker. ## Source: ossf-package-analysis (84540e9e44077c6ea24d8b8dc6093397f9ff6bcac74e53fe1dabfdd37d1a9b95) The OpenSSF Package Analysis project identified 'client-cookies-agent' @ 99.9.5 (npm) as malicious.
