Law enforcement from 27 countries seized the First VPN Service, also known as 1VPNS, in Operation Saffron.
A total of 33 servers associated with the infrastructure were taken down.
The service provided various VPN configurations, including single, double, and multi-hop options, and was reportedly used by cybercriminals.
The official website now displays a law enforcement takeover banner.
A press release detailing the operation is expected soon.
