Free VPNs and streaming apps are quietly transforming everyday devices into tools for cybercriminals. Unwitting users are allowing their internet connections to be hijacked and used to mask illegal activity, exposing them to serious security and legal risks. While not all residential proxies are illegal, abusers take advantage of anonymity coupled with cheap, unauthorized residential proxies to perform tasks that may be unethical, if not outright illegal at times.
Research from Infoblox Threat Intel indicates that the situation is more dire than previously assumed, as nearly two thirds (65%) of its Threat Defense Cloud customers made DNS queries to domains used to access or orchestrate residential proxy networks in 2026, totaling over 500 billion such queries per month. Criminals exploit these proxies for activities like fraud, online ad fraud, fake account creation, unauthorized data scraping, and bypassing regional restrictions on streaming platforms. Because their traffic blends in with legitimate user requests, businesses often struggle to identify and block these threats until real damage has occurred.
Most users are unaware that their devices are being weaponized. Permission is either buried in the fine print of end-user license agreements or never properly obtained at all. Once inside a network, these apps can silently forward requests from threat actors, who benefit from the anonymity of a residential IP. Victims may later face issues such as flagged accounts, CAPTCHA overload, or extra verification steps, as their IP addresses get tagged by reputation systems for suspicious behavior.
Certain categories of software are higher risk. Free VPNs, cheap IoT devices from unknown manufacturers, screen-recording or streaming software, and browser extensions can all serve as entry points for residential proxy abuse. These tools often lack transparency about their data and traffic practices, prioritizing monetization over user safety.
Avoiding this is easier said than done, but there are ways to reduce susceptibility to this kind of abuse. A software audit should be your first line of defense. Knowing what runs on all your devices and whether it is trustworthy or not is key to preventing exposure. Investing in a router or software service that blocks such requests would also go a long way, as would leveraging Protective DNS to monitor your network. To start, users can also use services to monitor and check their IP’s risk profile, allowing them to determine whether they are already a victim of abuse.
