Spam is down, alternative attack schemes are up.
According to a report from the Anti-Phishing Working Group (APWG), cybercriminals (a great word) are targeting classified advertising sites at an increasing rate.
Security Week published this graph. 6,6% of all attacks are directed at the classifieds sector. In 2010, this sector showed the highest growth. Popular platform for the attackers are obvious sites like Craigslist and Autotrader.
Naturally the biggest fields of online crime are finance and online payment services (at 33% and 38% respectively). As Jumio is in the final stages of development, these statistics and possible counter measures are highly interesting.
