There is certainly a value to social networking websites. Some serve professional networking purposes (such as LinkedIn). And others, like Facebook, have proved to be an effective means of connecting with old friends (for me, including ones I’d lost touch with completely).

It’s not news that we use these websites at our own peril. But here’s a couple of more reasons to be wary, both legal and technical.

A new Facebook notification? “You’ve been served!”

In what seems to be a legal first, a judge of the Australian Capital Territory Supreme Court has upheld the right of lawyers to serve legally binding court documents and notices by posting them on defendants’ Facebook sites.

Plaintiff MKM Capital applied to Master David Harper of the Supreme Court to use Facebook to serve notice of a judgment on two borrowers who had defaulted on a loan. The defendants had failed to repay a loan of $150,000 they borrowed from MKM last year to refinance their mortgage. After being granted a default judgment for the loan amount and for possession of the house after the couple failed to appear in court to defend the action, MKM then had to locate the defendants and serve them with the papers.

After hiring private investigators and 11 failed attempts to find the couple, the lawyers identified the Facebook profiles of the defendants, convinced the court that those profiles did in fact belong to the couple, and satisfied the court that communication through their Facebook pages was a sufficient means of communicating with the defendants.

Wormholes

It was just a matter of time before social networking websites became infected with computer viruses. And now it’s happened: Koobface, a Trojan worm, has been making its way through Facebook and to other social networking websites. The worm generates profile comments that encourage users to click through to an external website that pretends to offer a video to view, but then says that an upgrade of Adobe Flash is necessary first. Users who click on the “install” button infect their computer with the virus. The result? Enabling identity theft and click fraud.
