Committed TryHackMe walkthrough.
Hello guys back again with another walkthrough of Committed from TryHackMe. The walkthrough will be short this time. We are required to do some forensics on a git repository nothing too fancy but it teaches an important lesson. We first start a machine and download a zip file. Extract the entire contents then I’ll use on of the subtools of gitTools to get a copy of all the commits and grep for the flag. Without much say let’s jump in.
When we start the machine we get a system with the file that we need analyzed. It’s in a zip file called commited.zip.
I wanted to download the files to my machine and for this to happen i needed to know the ip address of the spawned system. I used the command
To get the IP Address of the system.
The IP Address was 10.10.217.58. Next step was to set up a web server on the remote system and given python was installed I used http.server library to set up a simple web server.
Sweet now we have the files on our system the next step was to extract the contents from the zip
I used the command
Looking at the extracted contents we have a .git directory. I used a tool called gitTools to extract the commits from the .git directory. I copied the subtool extractor top my current working directory
Then to extract all the commits i used the following command
bash extractor.sh commited extract
Looking at the screenshot below we successfully extracted all the commits
Next i just used grep to find the flag
grep -Ri "thm\|flag" .
Looking at the screenshot below we get the flag. We can now submit it and get the points
