The Top 5 Open Proxy Ports & How To Fix Them

Via eMail Battles.

Over the last few days we've prowled the dark side, compiling a list of computers vulnerable to exploitation as open proxies. We logged their IP addresses and the ports they left open for intruders.

We discovered that attackers generally prefer ports 80, 81, 3128, 8000 and 8080. They frequently get their wish, as ports 80, 3128 and 8080 are among those most often left open.

Their targets, however, are most likely to leave port 50050 open for exploitation. All told, ports 80, 3124, 3128, 8080 and 50050 comprise over 78% of all ports open for business as unwitting mules for proxying.
