Canadian national charged concerning the NetWalker ransomware

Sebastien Vachon-Desjardins was arrested and charged in relation to the ransomware for illegally obtaining $27.6 million. NetWalker is a dark web group of cybercriminals keen on attacking innocent organizations and demanding payment. It functions on “ransomware-as-a-service model,” bringing together “developers” and other “affiliates.”

The DoJ recovered about $455 million in cryptocurrency from ransom payments made in several attacks. The Bulgarian authorities were able to stop the “dark web” source that NetWalker utilized to pass messages to the victims.

Phishing emails were employed to infiltrate the victims’ computer networks where users are prompted to send log-in information. In other instances, users downloaded the malware. On taking control of the victims’ networks, NetWalker criminals start demanding for payment to allow access.

The recovered $455 million is just the tip of the iceberg. According to a Vancouver Island-based Threat Analyst, Brett Callow, NetWalker extorted around $1.4 million in only one case in 2020. Special Agent in Charge Michael F. McPherson of the FBI’s Tampa Field Office said about the action by the Justice Department:

This case illustrates the FBI’s capabilities and global partnerships in tracking ransomware attackers, unmasking them, and holding them accountable for their alleged criminal actions.
