Vidar - HTTP POST Payload Upload (T1041)
This rule detects HTTP POST connections initiated by 'AutoIt3.exe' which is indicative of Vidar Stealer attempting to exfiltrate data to its C2 server. The rule specifically looks for network events where the HTTP method is POST and joins them with process events where the initiating process is 'AutoIt3.exe'.
