The long-running Qakbot malware botnet was disrupted by international law enforcement action in August, but its operators appear to still have some capability and are continuing to run spam email campaigns that attempt to pass ransomware.
The infrastructure for the Qakbot malware botnet that has been a plague since 2007 has been dismantled by an FBI-led law enforcement action. The botnet was composed of over 700,000 infected computers, and is responsible for hundreds of millions of dollars in damages worldwide during its run.
