Seven high-severity exploit attempts and one that rates as critical -- that would be Conficker, of course -- made the March Threatscape Report from Fortinet, the Top of the Pops for the rightfully unpopular, released Friday.

Malware infection attempts made up the lion's share of threatening traffic, with spyware and phishing attempts together making up less than a third of attempts.
