New DeadBolt Ransomware Targets QNAP Devices, Asks 50 BTC For Master Key

Wednesday January 26, 2022. 02:00 PM , from Slashdot/Apple
ryanw shares a report from BleepingComputer: A new DeadBolt ransomware group is encrypting QNAP NAS devices worldwide using what they claim is a zero-day vulnerability in the device's software. The attacks started today, January 25th, with QNAP devices suddenly finding their files encrypted and file names appended with a.deadbolt file extension. Instead of creating ransom notes in each folder on the device, the QNAP device's login page is hijacked to display a screen stating, 'WARNING: Your files have been locked by DeadBolt.' This screen informs the victim that they should pay 0.03 bitcoins (approximately $1,100) to an enclosed Bitcoin address unique to each victim.

After payment is made, the threat actors claim they will make a follow-up transaction to the same address that includes the decryption key. This decryption key can then be entered into the screen to decrypt the device's files. At this time, there is no confirmation that paying a ransom will result in receiving a decryption key or that users will be able to decrypt files. The DeadBolt ransomware gang is offering the full details of the alleged zero-day vulnerability if QNAP pays them 5 Bitcoins worth $184,000. They are also willing to sell QNAP the master decryption key that can decrypt the files for all affected victims and the zero-day info for 50 bitcoins, or approximately $1.85 million.
