A security researcher has released an automated social network attack tool in an attempt to show just how vulnerable social nets are.Core Security vulnerability researcher Pedro Varangot thinks social nets are the next big frontier for automated spear phishing attacks, and at RSA he released code that he thinks proves it.

Rising user wariness about e-mail is leading to diminishing returns for phishers. As a consequence, Varangont argues, the spear phishers, whose success with targeted scams and come-ons shows the effectiveness of approaching targets by name.
