It also issues a DNS lookup of `<whoami>.0bcdniet6uubfi1lkxgx8qhpcgid65uu.oastify.com` as a secondary OAST exfiltration channel. The package self-describes as a 'Security research canary' but is published on the public registry and runs unconditionally on any installer's machine, leaking host identity and CI/GitHub repository context to a third party.\n\n## Source: ghsa-malware (65daf45d03c11c27cbf1be53eefe496baf57ab0319078e92875e2cb3dd72aec1)\nAny computer that has this package installed or running should be considered fully compromised.
