Visa issues security alert - Malicious Software and Internet Protocol (IP) Addresses

The Merchant Account Blog posts about a new Visa Security Alert on its blog - These are typically posted at:, but this one does not appear to be posted yet. I also received this alert early today via email as well.

This is one of the more detailed security alerts that I have seem, it includes a list of IP address to block, a list of malicious software and hashes to detect and a list of 5 mitigation strategies:

  1. Configure firewalls to scan for – and block – the attached IPs
  2. Utilize a Network-based Intrusion Detection System
  3. Utilize a Host-based Intrusion Detection System
  4. Properly Segment Network
  5. SQL injection
