Malware pushed by affiliate networks remains the primary growth factor of the cybercrime ecosystem
- - The fastest growing malware categories in the second half of 2011 were PPI (pay per installs) and information stealers.
- - Of the thousands of malware families, the “Top 50” generated 80% of successful malware infections.
- - Over 95% of enterprise networks have a security gap despite $20B spent annually on IT security.
- - Spear phishing attacks increase when enterprise security operations centers are lightly staffed or understaffed, particularly during holidays.
In the second half of 2011, pay-per-install (PPI) downloaders, worms, backdoors, and information stealers represented the four most prevalent categories of malware. PPIs are malware programs that charge a fee to download or distribute other malware programs. These programs differ from normal downloaders/droppers in that a PPI malware author gets paid for every successful install of another malware program. Of the top four malware categories, information stealers and backdoors present the greatest threat to enterprises.
