Residential Proxies Posed as National Security Threat, Calls for Government and ISP Action

The Problem with Residential Proxies

Residential proxies route malicious traffic through legitimate home internet connections, making it appear as normal user activity. This characteristic allows bad actors to bypass traditional IP-based blocking mechanisms used by internet services and social media platforms, as blocking these IPs would also affect genuine users.

These proxies are typically established without the homeowner's knowledge, often through free VPN apps reselling bandwidth, proxy SDKs embedded in games, or malware on devices like computers, routers, and smart TVs. LG recently banned proxy apps from its smart TVs after discovering that over 42% of its apps could covertly turn devices into proxies.

National Security Implications

The proliferation of residential proxies is presented as a national security threat. They contribute to data and identity loss for American citizens and can facilitate malware that records video and audio from infected devices. Furthermore, these networks provide infrastructure for foreign covert influence campaigns and are used in botnets for hacking and Denial-of-Service (DoS) attacks.

Calls for Action

The article suggests that the US government, potentially the NSA, should actively crack down on US residential proxy networks. Additionally, major American Internet Service Providers (ISPs) like Comcast and AT&T are urged to detect suspicious activity originating from customer IPs. They should then warn customers to scan their devices and identify the source of the proxy activity.

Such measures would not only address national security concerns but also benefit individual users by preventing their internet connections from being slowed down or their IPs from being banned due to unauthorized proxy use. The issue is not unique to the US, and other countries are encouraged to implement similar measures for a secure internet.
