What it detects

This rule detects WinSCP driven from the command line with an embedded session and scripted transfer commands, an exfiltration behavior used by BlackSuit ransomware operators. Attackers script WinSCP to push stolen data to attacker-controlled SFTP servers before encryption, so scripted WinSCP sessions on servers are a strong exfiltration signal.
