File Sharing Opens Users to Identity Theft
by Sassy Wed Nov 14, 2007 4:57 pm
Surprise! When you share files on your computer with the teeming masses on the Internet, you might be sharing more than just music and video files. Numerous peer-to-peer users are learning, the hard way, that file sharing is a quick and easy way to open yourself up to identity theft.
The story isn't at all new, but the Wall Street Journal is bringing it into better focus, with specific examples and an indication that this trend is exploding. One man pleaded guilty last week to stealing tax forms, credit reports, and loan applications from more than 50 people, through the file-sharing program LimeWire. He then used the info to open credit accounts in those people's names, the usual form that identity theft takes. In September, Citigroup lost more than 5,000 Social Security numbers because one of its employees was using LimeWire and shared the wrong network. Ditto for Pfizer in June, which lost 17,000 employee records the same way.
Finding this stuff online isn't hard. Search any P2P network for hot-button words like "taxes," "resume," or "loan," and you'll come across personal information in seconds. It's also easy to misconfigure your computer to inadvertently share this information. One or two clicks is normally all it takes to share the entire contents of your hard drive instead of a specific directory intended for sharing. And no, all the security software in the world won't help you if you make a mistake like this.
What should you do? For starters, don't use P2P at all if you don't know what you're getting into. As the WSJ notes, using a computer dedicated solely to file sharing is a potentially good solution; just keep anything you don't want shared off the PC altogether. (It also goes without saying that you shouldn't share copyrighted material, either, but that's a lecture for another day.) Some networks are safer than others; certain P2P apps, like BearShare, no longer allow DOC or PDF files to be shared at all. On the other hand, in my experience, LimeWire is the network most likely to turn up private information.
The full story also has information on corporate software that can help protect you by monitoring what you're sharing, called Tiversa. Check out the link below for more details.
