FBI's crackdown on Qakbot malware led to the seizure of servers and confiscation of $8.6 million, but it re-emerged stronger with new spam bomb attacks.
Qakbot's alleged mastermind, Rustam Rafailevich Gallyamov, adapted to law enforcement actions by using more deceptive tactics like spam bomb attacks tricking employees.
The attackers posed as IT staff in subscription emails to gain access to company systems, leading to data theft, encryption, and ransom demands.
Despite seizing funds from Gallyamov, he remains in Russia beyond the reach of US law enforcement, leaving organizations vulnerable to similar cyber threats.
