Man indicted in $27M ransomware fraud case affecting Maryland senior living provider – News

Sebastien Vachon-Desjardins, a Canadian national, was indicted on conspiracy to commit computer fraud, conspiracy to commit wire fraud, intentional damage to a protected computer, and transmitting a demand in relation to damaging a protected computer.

The government was able to seize approximately $454,530.19 in cryptocurrency from ransom payments to Vachon-Desjardins, as well as disable a “dark web” hidden resource used to communicate with NetWalker ransomware victims.

As part of the joint international effort, Bulgarian law enforcement seized computers affiliated with NetWalker. A dark web blog that posted the files of NetWalker victims who refused to pay the ransom now displays a graphic indicating that it was seized by government agencies.

According to court documents, once a victim’s computer network is compromised and data are encrypted, actors that deploy NetWalker deliver a ransom note to the victim. Hackers typically gain unauthorized access to a computer network days or weeks before delivering a ransom note, according to the Justice Department.

The department explained that NetWalker operates a “ransomware-as-a-service…
