ProxySmart is a commercial software platform designed to automate and manage large-scale SIM farms. It is commonly used in proxy and fraud operations, enabling users to control thousands of mobile SIM cards remotely. The platform streamlines the process of rotating SIM cards, changing IP addresses, and managing connectivity, making it easier to bypass security measures and conduct activities such as ad fraud, credential stuffing, or web scraping. ProxySmart's automation capabilities significantly reduce manual intervention, increasing efficiency for operators running illicit or high-volume proxy networks. Its use is typically associated with cybercriminal activities and can pose significant threats to online services and digital advertising ecosystems.
