  • /etc/passwd: you may be able to get to this from the GUI file manager.

    If not, open a terminal and type: cat /etc/passwd. Copy the relevant lines.

    To test the login, from a terminal, type su otheruser, replace otheruser with the username from /etc/passwd. It should ask for a password, put that in and it should log you in. Type whoami and make sure its the same username as you expected. Paste any errors here.




  • I think it perfectly highlights what can happen when the risk/severity is blown out of proportion. People will latch on to that and waste precious time and energy defending that.

    If the original guy had just published “CUPS has a RCE, firewall it if you haven’t already”, the issue would have been patched in the next release, and the world would have kept turning.

    It was a really cool bug, and a great find, it didn’t need the hype

    Thats a repo of existing malware. Be careful with it. You can use that to start reverse engineering an existing malware. Use a VM that isnt connected to a network.

    If you want to write something, go for it. Often malware is tailored to a single OS (Windows), so cross platform is less of a concern.

    The hard part of writing malware is doing it in an undetectable way, which will usually require deeper OS knowledge, which you’ll have to acquire over time. YouTube has some good videos if you hunt around.
