Security firm F-Secure has identified Adobe's Reader application as the top app targeted for exploitation on its security blog.
F-Secure notes that have seen in the first two months of 2010 it has tracked over 895 targeted attack files and Adobe Reader attacks continue to rise. In 2009, F-Secure said attacks on Adobe files were exploited in 49% of the targeted attacks, in comparison with Microsoft Word that was only 39%.
The security firm also indicated that the total number of attacks was on-pace to "more than double" last year's figure.
F-Secure notes the change by saying, "Primarily there have been more vulnerabilities in Adobe Acrobat/Reader than in the Microsoft Office applications."
F-Secure also details the work of an online group that has released a new malware campaign that exploits the vulnerabilities patched last month in the program. The attacks are targeted at financial and banking institutions with a PDF file referring to the G20 -- the group of top influential economic powers. F-Secure details graphically the attack here.
Although Adobe did not issue any updates today, F-Secure recommends that you still go to the Adobe site to ensure that your updates are current.
