Netflix, Hulu and a host of other content streaming services block non-US users from viewing their content. As a result, many people residing outside of the United States seek to circumvent such restrictions by using services that advertise "free" and "open" web proxies capable of routing browser traffic through US-based computers and networks. Perhaps unsurprisingly, new research suggests that most of these "free" offerings are anything but, and actively seek to weaken browser security and privacy.
