The Trouble with Tor

Good article describing Tor (The Onion Router), a system originally developed by the U.S. military in order to facilitate secure and anonymous communications. Tor works by sending messages over a series of routers - each router encrypts the message and sends it along to the next. Nobody but the receiver knows the final destination and the identify of the recipient. It has been used to hide the location of websites and online services, such as the Silk Road, a website used by drug dealers. Though Tor is secure, it can fail to protect its users; this article describes how. Agencies (mostly law enforcement) can infiltrate by setting up fake routers and monitoring traffic, sending malware to host machines, or simply targeting people who use Tor for more conventional investigations.
