Background for this topic.

A proxy is an intermediary that sends requests to a destination and returns responses, so the client and destination do not communicate directly. A forward proxy represents users or systems making outbound connections; a reverse proxy represents an application or service to inbound clients and may route traffic, terminate TLS, or enforce authentication. This tag generally concerns these network components, not browser-based privacy tools alone.

Security depends heavily on configuration and trust boundaries. A forward proxy can enforce egress policy and provide useful logs, but an exposed or misconfigured one may permit unauthorized relaying, while proxy logs can reveal sensitive browsing or business activity. TLS inspection requires controlled certificate deployment and careful handling of decrypted traffic. Reverse proxies reduce direct exposure of back-end services, but access controls must not rely solely on them, and forwarded client-IP headers must be trusted only from known proxies. During investigations, proxy logs help reconstruct connections, but shared addresses and address translation can complicate attribution.

911[.]re, a proxy service that since 2015 has sold access to hundreds of thousands of Microsoft Windows computers daily, announced this week that it is shutting down in the wake of a data breach that destroyed key components of its business operations. The abrupt closure comes ten days after KrebsOnSecurity published an in-depth look at 911 and its connections to shady pay-per-install affiliate programs that secretly bundled 911’s proxy software with other titles, including “free” utilities and pirated software.

Breach Exposes Users of Microleaves Proxy Service

Microleaves, a ten-year-old proxy service that lets customers route their web traffic through millions of Microsoft Windows computers, exposed their entire user database and the location of tens of millions of PCs running the proxy software. Microleaves claims its proxy software is installed with user consent. But research suggests Microleaves has a lengthy history of being supplied with new proxies by affiliates incentivized to install the software any which way they can -- such as by secretly bundling it with other software.
