Hints →

We find the user's name is Jessie most probably because there is a comment which comments this person to do something


With the open directories, we can see that the sitemap/.ssh is accessible and it has an id_rsa key in it and we can use that to try to login with this Jessie person and get access to the machine for that we go to sitemap/.ssh and copy the id_rsa file into id_rsa file for using our local machine and we will have to change its permissions mode to chmod 600 id_rsa then we can do

ssh -i id_rsa jessie@$IP

and we get access to the machine and we can get the user flag.

Get the file to our Machine from the server.
