Threat actors regularly target NAS devices to steal sensitive documents or deploy info-stealing malware since they are usually used to backup and share sensitive files.

"Recently QNAP has received multiple user reports of hackers attempting to log in to QNAP devices using brute-force attacks – where hackers would try every possible password combination of a QNAP device user account," the company warned. In these attacks, the threat actors use automated tools to login into Internet-exposed NAS devices using passwords generated on the spot or from lists of previously compromised credentials. QNAP warns customers of ongoing attacks targeting QNAP NAS (network-attached storage) devices and urges them to enhance their security as soon as possible.
