@Pytt4m There is TimeLine Explorer that is a nice spreadsheet viewer. Plaso also has the ability to export directly into elastic and then you can build Kabana dashboards.

#psort.sy -o elastic --server 127.0.0.1 --port 9200 --index_name mywebserver web.plaso.

This is probably the best way to visualize this data as you can filter/graph on any field and lots of options.

I typically go old school commandline and very surgical. If I'm full timelining something then I already have an idea of when. Then I'll do something like this...

#grep <date time> timeline.csv |cut -d ',' -f1,3,5,7,8,12 |grep -v '.a..'

In the above command:
Grep filters the date and time you want from the file. Use the format the file uses. "2021-03-12 15:00"

cut -d says use the delimiter comma

cut -f grab fields 1,3,5,7,8,12 ( i just made these up for the example)

Grep -v do not show file access times which is typically shown as .a... This also depends on what I'm investigating though, but initial triage I remove them.

I do this because of speed. Greping files is usually very fast and I dont have to setup anything additional to process the files. If the file is huge, I'll break out the couple days I'm interested in to make it faster.

#grep '2023-01-23' timeline.csv >2023-01-23-timeline.csv

If I need to do a graphical timeline for a report, I'll use Aurora and manually create it. Hope this helps!

The standard Apache "combined" log format is:

IPaddr - - [date] "method URI protocol" code bytes "referer" "user-agent"

Write a Linux command to output:

count IPaddr user-agent

Here "count" is the number of times each "IPaddr user-agent" combo appears. The output should be sorted by IP address.

For consumers of LastPass:

If your master password wasn't LONG and COMPLEX, I'd make it a priority to go through your Lastpass and change passwords on all the sites. Like... asap.

IMO don't abandon the idea of password managers, but strongly consider 1Password or Bitwarden.

I worked at LastPass as an engineer a long time ago. 7+ years ago. My 2 cents on the situation.

This is the worst breach LastPass has had. By a lot.

If you answered both with yes, you will like: https://forensics.wiki/

The page has recently migrated to a GitHub based system (yeah I know it is no longer a wiki, whatever :-) : https://github.com/forensicswiki/wiki.

@RyanDFIR, Joachim and Robert are currently working on this.
