Thankfully, our guidance is relevant to all situations where logs are unavailable to support an investigation.įor the rest of this article, I would like us to operate under a log-free paradigm – where the event logs cannot be utilised in an investigation. ![]() Without the event logs on a machine, you cannot use beautiful tools like Chainsaw to easily piece together the story for your client. ![]() It is a recognised behaviour of adversaries who wish to evade and frustrate investigators’ efforts to unravel the TTPs of a malicious campaign.
