On the Wisdom of Rolling Your Own Social Network

Koobface Worm Sharpens Facebook Security

The computer then becomes part of the Koobface botnet, which the security software firm Kaspersky Labs estimates is made up of 400,000 to 800,000 PCs worldwide. “That definitely makes Koobface one of the most significant botnets out there,” said Roel Schouwenberg, a senior researcher.

To halt Koobface, Facebook uses algorithms that can detect suspicious posts and hijacked accounts, looking for unusual behavior like log-ins from odd places and a surge in messages sent. Facebook also keeps a blacklist of malicious Web links to prevent them from being shared on the site. When Koobface posts find a way through, members of the operations team remove them.

The BuddyPress spam on The Daily Newarker seems infantile compared to the level of sophistication possible in social network malware attacks.

I’m beginning to question the wisdom of attempting to run a standalone social network.
