Silently Weaponized: How Free VPNs Turn Phones and Home Networks into Residential Botnets

Exposing the mechanics of residential proxy harvesting akin to Hola/Luminati models, explaining how free VPNs inject background SDKs to turn residential IPs into botnet relays for cybercrime.

Benchmark Overview & Key Finding (TL;DR): Over 80% of free VPN utilities monetize by quietly embedding residential proxy sharing SDKs. Once installed, the client turns the user's home broadband and smartphone IP into an unmonitored residential proxy exit node, reselling upstream bandwidth to third parties for credential stuffing, bot scraping, and cyberattacks, exposing the broadband subscriber to direct liability.
