ProxySmart's SIM Farm-as-a-Service Operation Raises Cybersecurity Concerns
A Belarus-based software platform, ProxySmart, has been identified as a key player in an industrial-scale cybercrime operation involving 87 physical SIM farms globally. According to Infosecurity Magazine, ProxySmart provides a web-based control panel, API, and remote access that supports SIM farm-as-a-service. This service enables device management, customer provisioning, automated IP rotation, network fingerprint spoofing, and plan enforcement, while implementing countermeasures against bots. Researchers from Infrawatch have reported that this ecosystem significantly lowers the barrier for operating and reselling mobile proxy infrastructure, with minimal eligibility checks across many downstream providers. The use of carrier-grade NAT, rapid IP rotation, and multi-carrier availability complicates IP-centric controls and attribution at scale. However, ProxySmart disputes these findings, claiming their infrastructure supports legitimate activities such as advertising verification, brand protection, cybersec...
