Infrastructure Diversity — Hunting In Shared Infrastructure

Infrastructure

Hunting Shared Infrastructure

Identifying Shared Infrastructure

After Discovery

  • Are there other suspicious features of the domain (age, reputation, categorization, VT hits, threat data match, etc)
  • Is the traffic regularly repeating? If so, at what time intervals?
  • For any content we can see (not encrypted), what type of activity is performed?
  • Is the activity limited to certain internal ranges / subnets?
  • How many assets do I see this activity originating from and how many requests per 24 hr period? If you are an MSSP, have you seen this in other customers, or in the same industry based customers before?
