How Residential Proxy Networks Have Become a Key Tool for Cybercriminals

Residential proxy networks use everyday devices like smartphones, home routers, and smart TVs to route internet traffic on behalf of third parties, making it appear legitimate. Cybercriminals exploit these networks to conceal their identities, evade detection, and carry out attacks such as credential stuffing, account takeovers, and financial fraud. Devices are often enrolled into these networks without users' knowledge — through malware hidden in pirated content or cracked software, or via SDK integrations buried in app terms of service. The rise of remote work since the COVID-19 pandemic has expanded this threat, as criminal traffic routed through residential IPs blends in with legitimate home-based internet activity. Large-scale data breaches have further amplified the problem by supplying cybercriminals with stolen credentials that can be weaponized through these proxy networks.
