zencleaner versions 1.0.0, 1.0.3, and 1.0.3.1, advertised as local Windows cleaning tools with no telemetry or outbound calls, secretly send license keys, machine identity details, and public IP addresses to a hardcoded Discord webhook. Additionally, the software clears Windows event logs, including security logs, to evade forensic detection. These actions contradict the product's claims and pose privacy and security risks.
