Residential proxy networks have become a pervasive tool for everything from high-end espionage to massive criminal schemes,

The Black Lotus Labs team at Lumen Technologies said it null-routed traffic to more than 550 command-and-control (C2) nodes associated with the AISURU/Kimwolf botnet since early October 2025. AISURU and its Android counterpart, Kimwolf, have emerged as some of the biggest botnets in recent times, capable of directing enslaved devices to participate in distributed denial-of-service (DDoS) attacks and relay malicious traffic for residential proxy services.

REM Proxy is a sizeable network, which also markets a pool of 20,000 Mikrotik routers and a variety of open proxies it finds freely available online. This service has been a favorite for several actors such as those behind TransferLoader, which has ties to the Morpheus ransomware group. SystemBC is a C-based malware that turns infected computers into SOCKS5 proxies, allowing infected hosts to communicate with a command-and-control (C2) server and download additional payloads.

Over the past few months, it has expanded aggressively, continuously leveraging infected devices to launch external attacks.
