Taking into account the FBI and Group-IB reports, this now also means that computers inside an organization that have been found to be infected with Qakbot must be isolated from the rest of the network as soon as possible, as they can serve as entry points for a ransomware gang.
At the time of writing, it is unclear if the ProLock ransomware was created and managed by the Qakbot gang, or if the ProLock gang rents access to Qakbot-infected hosts part of a Crimeware-as-a-Service scheme.
In the case of ProLock, the FBI says this group gains access to hacked networks via the Qakbot (Qbot) trojan.
