This post is to summarize some security incidents investigation steps using DarkTrace.

Investigation methodology

Any incident responder will always begin by asking some high-level questions concerning the incident under investigation – regardless of it being an adware infection, a banking trojan, ransomware, an active intrusion or any other form of cyber security incident.

The most important questions usually are:

  • How did the infection occur? (To prevent the same initial infection vector in the future)
  • What behavior is the infected device exhibiting? (To understand the threat and the risk of the infection)
  • What Indicators of Compromise (IoC) are seen? (To update other security tools and to use for further investigation)
  • Are other devices infected as well? (To assess the extent of the infection)
