Cybersecurity researchers have uncovered a Belarus-based software platform which is helping SIM farm operators support cybercrime on an “industrial scale.”

In a new report published yesterday on April 21, Infrawatch said that it had identified 87 instances of ProxySmart control panels in 17 countries and 94 phone farm locations. These farms are located across 19 US states, as well as countries in Europe and South America.

“ProxySmart is publicly associated with a Belarus-based vendor footprint and offers an end-to-end stack for operating and monetizing a physical farm, including device management, automated IP rotation, customer provisioning, plan enforcement, and anti-bot countermeasures,” the report explained.

“Technical analysis indicates operator capabilities consistent with large-scale evasion enablement, including automated IP rotation, remote device control, and network fingerprint spoofing.”

SIM farms enable a range of cybercrime activity such as smishing, premium-rate number fraud, bot sign-ups and one-time password interception. They can also be used by nation states, with the Russian authorities using them to spread disinformation in Ukraine.

A large percentage of this ecosystem is managed by ProxySmart, effectively enabling “SIM Farm as a Service,” Infrawatch claimed.

“The platform is marketed as a turnkey solution rather than a tool intended only for highly technical operators,” the report continued.

“Its public-facing materials advertise a web interface, API, remote access, documentation, and support, presenting SIM farm deployment as a productised commercial setup rather than a specialist engineering effort. This likely lowers the technical barrier to establishing and operating mobile proxy infrastructure.”
