Around since , QakBot infects computers, installs a key logger, and then sends banking credentials to remote Command and Control C2 servers. This is a stealthy approach in post-exploitation because it makes it very difficult for IT security to spot any abnormalities.
After all, to an admin or technician watching the network it would just appear that the user is web browsing — even though the RAT is receiving embedded commands to log keystrokes or search for PII, and exfiltrating passwords, credit card numbers, etc.

It has introduced, for lack of a better term, middle-malware, which infects computers, but not to take user credentials! In effect, the entire Web is their playing field! It turns out to be the security threat and leaves the doors open for malicious activities.
