Q

How does the log2timeline.py tool function? Why is inputting local timezone for the image important?

A

It extracts events from a group of files, mount point, or a forensic image and saves results in a Plaso storage file. It is important to add the local time zone so that it can convert it to UTC and match the other files.

What tools can I use to analyze timelines at scale?

Databases like Splunk or ELK are good for investigating multiple timelines. To search for IOC’s in timelines, use yara_match.py. To work with multiple timelines in real-time with other investgators, use Timesketch.
