The attackers behind the RobbinHood Ransomware are exploiting a vulnerable GIGABYTE driver to install a malicious and unsigned driver into Windows that is used to terminate antivirus and security software.

When performing a network-wide compromise, ransomware attackers need to push out a ransomware executable as quickly as possible and to as many systems as they can to avoid being detected.

One protection that can get in their way of a successful attack, though, is antivirus software running on a workstation that removes the ransomware executable before it can be executed.
