A few months ago, we warned you about fake Java updates and suggested that the best thing you could do to protect yourself was to keep all of your software updated.

One way criminals take advantage of software that isn’t updated is to craft PDF files that exploit Adobe Acrobat and Adobe Reader vulnerabilities. These files contain a JavaScript that runs when you open the file. The embedded JavaScript could contain commands to download and install malicious software (malware).

The Microsoft Malware Protection Center recently posted a list of files names commonly used for malicious purposes. They also warn that file names change so often that you need to exercise caution with all email attachments, especially those you receive from unknown sources or those you receive unexpectedly from known sources. They also encourage you to use extreme caution when accepting file transfers from known or unknown sources.

Do not open files with the following file names:

  • pdf_new[1].pdf
  • auhtjseubpazbo5[1].pdf
  • avjudtcobzimxnj2[1].pdf
  • pricelist[1].pdf
  • couple_saying_lucky[1].pdf
  • 5661f[1].pdf 7927
  • 9fbe0[1].pdf 7065
  • pdf_old[1].pdf

  • HOW MANY PEOPLE OUT THERE GET CONSTANTLY HIT WITH THE "AW SNAP" CUT OFF? I WOULD LIKE TO KNOW HOW TO GET RID OF IT.

  • IE9 on Win 7 takes 15 seconds to open (most of the time).  Could this we due to Microsoft Security Essentials "checking" IE9?
