Summary

C&C-related traffic in targeted attacks is often difficult to locate. Attackers change and redirect addresses, use legitimate sites and even set up C&C servers inside a company's network. Moreover, most security technologies focus solely on detecting and blocking addresses that are known to be malicious at that point in time. This is problematic because reputation scores constantly change. Addresses that are considered safe today can easily become malicious within the next hour or day.

Recommendation

Retro Scan examines historical web access logs to help you discover suspicious connections regardless of when the address is identified as malicious. Trend Micro recommends to enable Retro Scan to provide better protection and minimize the impact of targeted attacks.
