QNAP warned customers today of ongoing attacks targeting their NAS devices with cryptomining malware, urging them to take measures to protect them immediately.
Customers who suspect their NAS is infected with this bitcoin miner are advised to restart their device, which may remove the malware.
NAS devices are an attractive target for attackers, and this is not the first time QNAP systems were targeted by cryptomining malware this year.
In March, researchers at Qihoo 360's Network Security Research Lab revealed that a cryptominer dubbed UnityMiner was hijacking QNAP NAS devices unpatched against two pre-auth remote command execution vulnerabilities in the Helpdesk app.
In January, QNAP users were also urged to defend their devices from a malware campaign that made them unusable after spawning dovecat and dedpma processes that would hog up almost all system resources.
QNAP customers who want to secure their NAS devices from attacks further are advised to follow these best practices.
