The 'Cisco Secure Firewall - Wget or Curl Download' detection rule targets suspicious outbound connections made by command-line utilities such as curl and wget. It analyzes Cisco Secure Firewall Threat Defense logs to detect allowed connections (action=Allow) where the EVE_Process indicates the usage of these tools. While these utilities are typically used for legitimate purposes, such as software updates, adversaries can exploit them to download malware or establish command-and-control infrastructure. Therefore, this analytic serves as an early-warning mechanism for potential download phases in an attack framework. The detection searches for connections that may indicate malicious use, aiming to empower security operations to identify threats linked to unwanted downloads.
