On execution, it collects installer host identifiers (current working directory, home directory, hostname, username) and reads the contents of /etc/resolv.conf, /etc/passwd, and /etc/hosts, serializes them as JSON, and transmits them over a TLS TCPSocket POST to the hardcoded host d8mjdyfukgwrvkth4n83toa0xr3lrgf5.oastify.com. Prior to the HTTP POST, the script performs a DNS resolution of the same oastify.com subdomain, providing a secondary out-of-band beacon via the attacker's DNS logs. oastify.com is PortSwigger Burp Collaborator infrastructure; a hardcoded unique subdomain in a published gem is a dedicated exfiltration channel to the publisher, not a legitimate telemetry sink.\n\n## Source: ossf-package-analysis (ba322db91ecd6b863e8b06aa24b804a27f29cf2c8e2954bc1e77d7dc45e2fd52)\nThe OpenSSF Package Analysis project identified 'shoaib-unity' @ 1.0.1 (rubygems) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n","id":"MAL-2026-18461","modified":"2026-11-02T21:15:06.976400822Z","published":"2026-11-02T09:50:50Z","references":[{"type":"PACKAGE","url":"https://rubygems.org/gems/shoaib-unity/versions/1.0.1"}],"schema_version":"1.9.2","summary":"Malicious code in shoaib-unity (RubyGems)"}
