FBI Seizes VirtualLine Bulletproof Hosting Infrastructure

The FBI and U.S. Attorney's Office for the Eastern District of Virginia (USAO-EDVA) executed an international operation to seize the VirtualLine domain, a prominent bulletproof hosting provider. VirtualLine facilitated various cybercriminal activities, including child sexual abuse material (CSAM) distribution, ransomware command-and-control (C2) operations, and infostealer hosting, by systematically ignoring abuse complaints. Technical investigations leveraged blockchain intelligence from TRM Labs and Chainalysis to trace illicit cryptocurrency inflows, primarily Bitcoin, used for service payments. The seizure includes critical infrastructure components: DNS/registrar records, server IP ranges, hosting control panels, and server logs. This action dismantles a key logistical enabler for ransomware operators and money laundering syndicates.

• Operation Overview: Enforcement Action

  • Led by the FBI and USAO-EDVA in coordination with international law enforcement partners.
  • Target focused on VirtualLine's role as a bulletproof hosting provider for criminal entities.
