Adversaries may enumerate installed software and versions to identify security controls, management tools, or software that could shape follow-on behavior. ATT&CK classifies this behavior as Software Discovery (T1518). The read-only host-inventory examples here cover Windows, macOS, Debian-based Linux, and RPM-based Linux; choose the procedure that matches the host rather than executing these platform alternatives in sequence. ATT&CK also lists ESXi and IaaS for T1518, but this record does not provide procedure variants for those platforms.
