If you use any Adobe products, like Flash Player, Adobe Reader, or Acrobat, it would be a good idea to run your updates. Several patches in the last 6 months have clearly indicated that Adobe is having trouble keeping their products safe.
Adobe Reader users could fall prey to PDFs loaded with malware warns Adobe
The attacks use the "launch" functionality of the Adobe Reader/PDF technology, with the attacker able to bypass the security warnings given to users when they choose to open PDF documents from unknown sources.
"This is a good example of powerful functionality relied upon by some users that also carries potential risks when used incorrectly by others," said Adobe in a blog on the threat.
"The warning message provided in Adobe Reader and Acrobat includes strong wording advising users to only open and execute the file if it comes from a trusted source. The default option within the dialog box is to not execute," it said.
Adobe has offered workarounds to mitigate the risk of attacks while it works on a full fix.
