What Are Proxy Browsers? How Cybercriminals Use Them In Attacks

Proxy browsers route traffic through intermediary proxies and are dual‑use tools: they support privacy and testing but are widely abused by cybercriminals to hide origins, rotate IPs, and scale attacks such as credential stuffing, phishing, scraping, command-and-control, and click fraud. The report highlights why proxy browser traffic is hard to detect—shared proxy infrastructure, TLS encryption, and rapid IP cycling—and recommends layered defenses (deep packet inspection, TLS fingerprinting, geo-velocity/impossible-travel detection, user behavior analytics, and reputation-based filtering) plus continuous third‑party monitoring to reduce supply‑chain and vendor exposure.
