detect fraudulent residential proxies fraud has become a thorn in the side of marketers, hurting their campaign ROI and putting consumer trust at risk. Fraudsters use a variety of tactics to create duplicate accounts, bypass IP blocking, take advantage of free trials, commit ATO, and engage in other abusive behavior that can wreak havoc on companies. Unfortunately, most ML models are not designed to detect these attacks, especially when using a residential proxy.
Residential proxies are distinct from commercial proxies in that they use real IP addresses from residential Internet Service Providers (ISPs) rather than those from data centers. This gives residential proxies a veil of legitimacy that is hard to detect and allows fraudsters to disguise their activity as legitimate users. This is why it’s important to carefully select RPPs that have strong customer verification, relevant certifications, and transparency about the origins of their proxies.
