Visa has issued a security alert (relating to the recent Heartland breach?) outlining some specific applications and IP addresses to look out for.

What is unique about this alert is that Visa gave a very specific list of malicious applications to search for on a network/computer, and a specific list of IP’s to block.

This would indicate that Visa has explicitly identified threats, where they are originating from, and these locations are static enough that blocking them would actually do some good...
