Description
The RubyGem 'agentic-call-control' version 1.1.8 contains malicious code in its native extension script that executes during installation. This script collects sensitive host information including directory paths, hostname, login name, and contents of system files such as /etc/resolv.conf, /etc/passwd, and /etc/hosts. It then serializes this data as JSON and exfiltrates it over TLS to an attacker-controlled domain. Additionally, it performs a DNS lookup to the same domain as an out-of-band beacon. This behavior is unrelated to any legitimate build or installation process and constitutes unauthorized data harvesting and exfiltration.
