According to Cisco, the number of Web-based attacks targeting Java vulnerabilities has increased throughout the past quarter, while the rate of PDF exploits has decresed.
In its Global Threat Report for the third quarter of 2010 [pdf
], the company reveals that, on average, enterprises encountered 133 Web malware attacks per month, with August being the busiest one.
Of those, 65 percent did not involve exploits or were blocked before the exploit code executed.
As far as the rest go, the most commonly targeted vulnerabilities were located in Java, Adobe Reader and Flash Player.
Java exploits were the most prominent ones. They started by representing 5% of all Web malware attacks in July and ended by accounting for 7% in September.
