Netwalker Ransomware

The Netwalker ransomware was launched in 2019 as a RaaS operation. The goal of the operator was to recruit affiliates to deploy the ransomware for 60-75% profit on all the ransom payments.

In connection with the ransomware operation, Vachon-Desjardins acted as an affiliate. In addition to US companies, at least 17 Canadian entities are believed to have been targeted by him.

A ransomware attack takes advantage of corporate systems to steal data and to eventually encrypt devices and entire networks. As a result, the threat actors extorted the victims into paying a ransom demand so that they could recover files and prevent data from leaking.
