Memory Timeline Analysis using Sleauthkit - mactime

mactime creates an ASCII timeline of file all activity. This tool can be used to detect anomalous behavior and be able to reconstruct events, its output is a .txt format that contains reconstructed activity.

Why Timeline?

Reconstructing the events can play an important role during the investigation, because it allows the investigator to rebuild the activities happened before and after the event was first detected. It allows the investigator to have a bird’s eye view of the activities done by a certain malware or a threat actors and used this to construct a systematize action.
