Cybersecurity experts have spotted a brand-new malware targeting NAS (Network Attached Storage) devices. Its name is QSnatch, and it goes after QNAP NAS devices specifically. Malware researchers managed to spot the activity of this new threat in the middle of October 2019, as communication between the malware and a particular C&C (Command & Control) server was detected. At first, the experts believed that this newly uncovered malware targets systems operating with Windows, but upon a detailedinspection, it became clear that the QSnatch threat aims at infiltrating NAS devices instead.
It is yet to be determined what infection vectors have been used by the QSnatch authors in the propagation of this threat. The QSnatch threat plants its bad code in the firmware of the host and then runs it as a legitimate process. Then, the QSnatch malware makes sure to establish a connection with the attackers' C&C server. Using various domain generation algorithms, the QSnatch threat is capable of fetching additional harmful payloads. Once this is completed, the QSnatch malware will be able to cause a fair bit of damage to the compromised host. The QSnatch threat is capable of:
- Prevent any applications from applying updates as this might tamper with its unsafe activity.
- Prevent the QNAP MalwareRemover application from launching if the users have installed this program on their PCs.
- Load new features from the attackers' C&C server.
- Alter the active time-based job schedulers (cronjobs) and init files (initialization scripts that are executed to start necessary processes as part of the boot process).
- Gather all login credentials present on the infected host and transfer them to the C&C server of its operators.
QSnatch can be Removed from an Infected Device
The QSnatch malware is set to contact the C&C server of the attackers at certain time intervals.
However, you can wipe off the QSnatch malware from your system. However, this may require you to reset the compromised device to factory settings, which means that all the data you are storing on it also will be lost permanently. Then, you have to apply an update that has been released as this will provide further protection for your NAS device.
