Security News > 2022 > June > QNAP 'thoroughly investigating' new DeadBolt ransomware attacks
Network-attached storage vendor QNAP once again warned customers on Friday to secure their devices against a new campaign of attacks pushing DeadBolt ransomware.
"QNAP recently detected a new DeadBolt ransomware campaign. According to victim reports so far, the campaign appears to target QNAP NAS devices running QTS 4.x," QNAP said today.
As QNAP said, upgrading the firmware on a compromised device will allow the built-in Malware Remover app to automatically quarantine the DeadBolt ransom note known to hijack the login page.
Because QNAP devices are also being targeted with other ransomware strains, including Qlocker and eCh0raix, all owners should keep their devices up to date to secure their data from future attacks.
As seen during previous attacks targeting QNAP NAS devices in late January and hitting thousands of victims, DeadBolt ransomware hijacks the device's login page to display a screen stating, "WARNING: Your files have been locked by DeadBolt."
DeadBolt ransomware has also hit ASUSTOR NAS devices in February, allegedly using a zero-day vulnerability.
