16 Questions You MUST Ask Before Hiring Any IT Company
QNAP recently addressed a critical security vulnerability you need to be aware of.
Previous to the fix, the company had included hard-coded credentials to serve as a backdoor to the device.
Unfortunately, hackers became aware of this and began abusing those credentials. That resulted in a number of confirmed instances where hackers gained access to the device via the backdoor, then installed ransomware and encrypted all of the files on the device.
The issue is being tracked as CVE-2021-28799, and at this point, has already been resolved.
