The U.S. Treasury Department sanctioned a VPN provider and two individuals on July 13 for supplying infrastructure and tools used in ransomware attacks that have hit U.S. hospitals, financial services firms and municipal governments.
The Treasury’s Office of Foreign Assets Control designated First VPN Service, aka 1VPNS, and its administrator, Dmytro Rashevskyi, along with Yegeniy Vladimirovich Silayev, a Belarusian national who sells “cryptors” that disguise malware from security systems.
The office said ransomware groups using 1VPNS infrastructure count hospitals among their victims, part of a pattern of attacks that have cost U.S. businesses and critical infrastructure providers billions of dollars.
“Under President Trump’s leadership, Treasury is using every available tool to disrupt the cybercriminal ecosystem and protect the American people,” said Gene Lange, who is performing the duties of undersecretary for terrorism and financial intelligence, in a news release.
The action follows a May 2026 takedown of 1VPNS’s website and infrastructure by European law enforcement, supported by the FBI’s Boston Field Office, and is coordinated with the United Kingdom’s Foreign, Commonwealth & Development Office, which is sanctioning related actors the same day. The designations stem from President Donald Trump’s March 6 executive order on combating cybercrime and cyber-enabled fraud against Americans.
All property and interests of the designated individuals and entity within U.S. jurisdiction are now blocked, and U.S. persons are barred from transactions involving them.
The sanctions add to a growing federal effort to target the infrastructure providers enabling ransomware groups that have repeatedly disrupted hospital operations and patient care nationwide.
