Factoids

Some notes of interest about the Sobig worm:

It was originally developed by or for spammers so that they could take advantage of unwitting, vulnerable home PCs to send spam, a useful technique when ISPs quickly shut down the accounts of more open spammers.

On Friday, all infected computers attempted to download software from 20 servers, 19 of which were taken offline in order to avert the internet traffic jam this would cause. Those that managed to contact the 20th server only redirected their hosts to a porn site.

The computers that didn't succeed in downloading the software on Friday will try again every Friday and Saturday until Sept. 10. At that point, the virus will mercifully delete itself, finally ending the e-mail deluge.
