Description
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.
