With QNAP devices exploited for ransomware attacks in the past, users running one of the aforementioned versions are urged to update to the latest version to mitigate potential threats.
The development comes weeks after the Taiwanese company disclosed it took down a malicious server used in widespread brute-force attacks targeting internet-exposed network-attached storage (NAS) devices with weak passwords.
