AquaPurge is a log-clearing and manipulation utility used to remove traces of malicious activity from compromised Cisco Secure Email Gateway and Secure Email and Web Manager appliances running AsyncOS. It selectively removes attacker-associated entries from system logs, hindering forensic analysis and incident response while preserving unrelated log content. AquaPurge was observed as part of the UAT-9686 intrusion toolkit following exploitation of CVE-2025-20393, alongside the AquaShell backdoor and tunneling tools including AquaTunnel and Chisel. Cisco Talos assessed UAT-9686 with moderate confidence as a China-nexus advanced persistent threat actor.
