The Merchant Account Blog posts about a new Visa Security Alert on its blog - These are typically posted at: http://usa.visa.com/merchants/risk_management/cisp_alerts.html, 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:
- Configure firewalls to scan for – and block – the attached IPs
- Utilize a Network-based Intrusion Detection System
- Utilize a Host-based Intrusion Detection System
- Properly Segment Network
- SQL injection
