- Residential proxies route traffic through real home internet connections, making abuse appear as legitimate user activity.
- They are created unknowingly through free VPN apps, proxy SDKs in games, or malware on devices.
- Blocking residential proxies is difficult because it would also cut off genuine users from the same IP ranges.
- The threat intelligence industry profits from tracking these IPs but has perverse incentives to not eliminate the problem.
- Residential proxy networks pose national security risks including data loss, malware surveillance, influence campaigns, and botnets.
- ISPs should detect suspicious activity and warn customers to clean their devices and remove proxy software.
