Did you know that there's a secret plan by ISPs to kill off the Internet as we know it and replace it with a TV-like subscription? This scandalous news may not be in the mainstream media, but you can read it in a spam message reported on by the Symantec Security Response blog.

The scam about the Internet TV conspiracy is more interesting than the average spam, but what's really interesting here is the attachment to the e-mail, which is a malicious Acrobat file detected by Symantec's products as Trojan.Pidief.A that exploits a famous Adobe Acrobat vulnerability announced in 2007.

That vulnerability affected versions of Acrobat up to 8.1 on Windows XP (not Vista) and was only patched in the 8.x generation. 7.x users were left to the wolves.

Acrobat is one of those core applications now that is critical for almost anyone and heavily attacked. If you're not going to be aggressive about applying updates, you really should look at using an alternative reader.
