An "open proxy" is a machine that has been misconfigured to forward requests back out to the Internet. Hackers constantly rescan the Internet looking for these open proxies, usually HTTP proxies at ports 80, 8080, and 3127, or SOCKS at port 1080. Hacker websites maintain lists of active misconfigured proxies. When hackers want to be anonymous, they choose one of these proxies at random, they configure their web browser to go through the proxy. In this manner, anything they do appears to come from the proxy's IP address, and not from the hacker's IP address.
