Following a wave of ransomware attacks, network-attached storage appliance manufacturer QNAP Systems says it is urgently working on finding a solution to remove malware from infected NAS devices.
The Taiwanese company, which makes both NAS and professional network video recorder solutions, has long been urging users to improve the security of their devices.
With QNAP NAS devices being targeted by ransomware families known as Qlocker and eCh0raix, the company is now advising users to download and install the latest Malware Remover version and scan their devices for any sign of infection.
The NAS manufacturer has updated the Malware Remover tool for platforms such as QTS and QuTS hero "To address the ransomware attack," and tells users they should leave their NAS devices up and running if data on them has been encrypted.
Users should also "Modify the default network port 8080 for accessing the NAS operating interface," QNAP says.
Tracked as CVE-2021-28799 and considered critical severity, the flaw can be abused by remote attackers to log into QNAP NAS devices.
