Summary: Malicious code in shoaib-unity (RubyGems)
Details: Source: amazon-inspector (01fd98b807f4f85a6e016b143dec086ea16de731fb1de0cd84763dbf5d8f6919) The gem declares an extension script (mkrf_conf.rb) that runs automatically during `gem install`. 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.
