    got a shell as low level user.
    steganography? what is this?

    EDIT: AH HA!... I was on the right track

    The box is unstable as hell. My shell is dying like every 2 minutes

    some users can't connect to the box, some users just don't know what to do and press reset button. It happens a lot for poison box.

  • Rooted! This was such a headscratcher for a PenTest beginner, but I learnt a hell of a lot.
    I can now see why this is rated fairly easy.

    Here are my tips now I have rooted:

    User -

    First things first, simple basic recon. Make sure your scan is set to capture more than just the basics. Start to learn how to use nmap rather than the Zenmap GUI.
    There are a few articles online that discuss the types of scans you can run. A simple Metasploit search on your findings will give you a shell.
    Next, all I can say is look around your folders. " ls -a " will help. The rest of the hints are all over this thread.
    Finally, with the contents of the discovered file, there is a big hint. I had to learn to use a Linux s*** tool rather than windows, the file you need is obvious and is one of the first things you'll see when you start this box.
    I gathered the low priv user shell and user flag after this.

    Root -

    This was a real lesson for me but learnt a lot. What others have said in here is true. Enumerate the host as much as you can. Below I will link what helped me...
    Here you will find a specific binary file, you need to pull out the readable data and you'll find something you can have a play with. After that its a simple go-to hacker move to give you the root user shell and flag.

    Here are some articles I found helpful:

    Hope this helps, have deliberately tried not to give too much away to keep in line with the rules.

    PM if you need help

    (thanks to all who helped)

    Rooted. Very interesting Priv Esc method. I can't believe i executed it and i missed it in the first time. This machine can be completed under 3 minutes.

  • Can someone please PM me with some help. I have got on the box and found the user flag but i cant get the priv esc to read the file. I have been at it for ages now.

    Privesc comes after, look at my hints above.
  • Hey guys, this was my first owned box, and I really enjoyed it.

    First I got root but I never even saw that .b**** file everyone is talking about.
    Can someone please PM me what were the proper steps for getting the user first.
    Thank you.

    P.S. A hint for all the people that are looking for root and have found the fun file and are wondering what to do with it, just try commands ;)

  • hi guys, is we need stegano on this machine?

    since I didnt found anything intresting.

    xterm

  • Luckily getting a shell was easy thanks to hints left regarding i** and then enumerating the possible ports that service would use. This matched up to a nicely to a msf module.

    Finding the .b**** file was a bit tricky but I was able to figure out what it meant after reading "steg" on the forums here it hit me what it was. Pretty cool stuff using that tool.

    And MANY thanks to @masterrabbit for the hint on how to get root. I had to do some enumerating over and over and then saw the binary that isn't a normal one.

    Got user, was quite fun, and deceptively simple ... which is easy to say in hindsight.
    Been trying for root for a few hours now, and I think I might have something weird in binaries (v******r).
    Can anybody tell me in PM if I'm on the right path, or if I'm going down a rabbit hole ?

  • Got user, thanks to @masterrabbit for help. Onto root!

  • Hi
    Could someone help me with the shell?
    I guess I have the right exploit found but no chance to get a shell.

    any hints for priv esc would be appreciated.
    feel free to PM me.
    thank you

    banging my head to the wall with no luck with privilege escalation to root. Had no problem gaining low level access but root became impossible. Went through the binaries already with no luck :/ would highly appreciate if one of you could PM me with the solution

  • Had no idea about stego before this, was able to own user and root thanks to @masterrabbit 's tips

  • rooted,

    trying so hard to find the exploit, but someone patch that vuln , thanks for @masterrabbit ,without you I will stuck mate.

    xterm

  • Anyone needs help with stego pm me
  • Unable to connect using metaspolit today when I was connecting fine with it last night. Can anyone PM me with some help would be greatly appreciated.

    Many thanks! I haven't solved either of these yet, but I find this kind of help the most beneficial to learning and not banging your head against the wall for hours. Thanks!
  • Finally rooted it. thanks, @sixtonspacefly

  • Fun CTF style box. I really enjoyed it. Same as a lot of people here I spent a lot of time figuring out the PrivEsc part. Which in the end is very simple. But if you aren't at all familiar with this method, like me, you've got some learning to do before you can own the box.

    I think the best hint for root is to compare what you have on your attacking system with what is on Irked. Once you find this file, you're on the track to owning the system!

    For those still stuck, keep on and "try harder", you will learn something in the end. Shout out to @sixtonspacefly for the subtle nudge I needed to get on the right track.

  • Not sure i got root the intended way, anyone could PM me and discuss solution? :)

  • Got the user flag, stuck in priv esc. Read all the comments and hints but still can't get the file. I looked at the files with sticky bit set, but now sure which to choose and how to exploit that binary. If I am looking at wrong place please can someone redirect me? PM me on which binary to look for, please.

  • Hi I was wondering if anyone could help me get through the first step please just a little nudge would be nice I have an idea but some reassurance would be nice

  • Finally got root. The key is to enumerate and find potentially exploitable suid. Run you favourite enum script on your personal box and compare suid. A couple of them will be off. This helped me narrow down the vulnerable suid. From there just run the program using strings to see how it works. The rest is to spawn a shell using it. Cool Box by the way.

    Hello. I manage to get the user shell. But I can't able to find a way to get root. I enumerate a lot and I read the posts that is written in the forum. I think Im in the right way but can't manage to get the root yet. Can anyone PM me and give me a hint?

    EDIT: Got the root. @Jkr Thanks for help.
