Well right clicking has been blocked on this level. What can I do !? Oh wait, I was using curl to begin with another easy level.

More curling (and a little bit of linux basic spells to get the password -> I store the password in a file called natas1 and cat it to the curl command)

URL=http://natas1.natas.labs.overthewire.org

curl --user natas1:$(cat natas1) $URL

Once again, the password is in the HTML source code. Easy peasy.

Just to practice the sed command, I decided to use it to save the password to a file called natas2.

curl --user natas1:$(cat natas1) $URL | 
grep "natas2" | sed 's/.*is //' | sed 's/ -*.//' > natas2
