Security News > 2022 > January > QNAP warns of new DeadBolt ransomware encrypting NAS devices
QNAP is warning customers again to secure their Internet-exposed Network Attached Storage devices to defend against ongoing and widespread attacks targeting their data with the new DeadBolt ransomware strain.
All QNAP users are urged to "Immediately update QTS to the latest available version" to block incoming DeadBolt ransomware attacks.
As BleepingComputer reported yesterday, the DeadBolt ransomware group started attacking QNAP users on January 25th, encrypting files on compromised NAS devices and appending a.deadbolt file extension.
These ongoing DeadBolt ransomware attacks only impact exposed NAS devices and, given that the attackers also claim to use a zero-day bug, it's advised to disconnect them from the Internet just as QNAP recommended in today's warning.
Today's warning is the third one QNAP issued to alert customers of ransomware attacks targeting their Internet-exposed NAS devices in the last 12 months.
The company also urged all QNAP NAS users to secure NAS devices exposed to Internet access on January 7th, at the same time alerting them of active ransomware and brute-force attacks.
