Lloyd Borrett, Security Evangelist for AVG (AU/NZ) says,"Being aware of what products are being targeted by the bad guys may help youas well, so it may be useful to know that at the moment Adobe products arevirtually the number one target across the world with millions of PCs being hitby infected Adobe PDFs. Others are being introduced via Adobe Flash ads via Facebookand other social media web sites.”
Attackers send a file that has malicious code embedded init. Once the file is opened, the computer is infected, typically with some formof identity theft malware that then steals data.
The Adobe PDF and Adobe Flash browser plug-ins are also usedin ‘drive-by download’ attacks where malware is downloaded onto the PC whilethe user is surfing the web.
"Adobe products, just like Microsoft Windows and MicrosoftOffice, have near universal use on home and business computers making theseapplications prime targets for the bad guys,” Borrett continues."Unfortunately, since the bad guys realised this and turned their attention tofinding security holes in them, they have been very successful.”
Of course, the easiest way to avoid the risk of beingcompromised via these Adobe products is not to install them! However, this is virtually impossible formost home and business Internet users.
