Need help with I know mag1k

D4n1aLLL · December 2, 2017, 2:30pm

I need hints on how to decrypt the cookie obtained from login & logout request i know this challenge has something to do with that iknowmag1k cookie and i also know there are some url encoded characters which i decoded but still i cant figure out what type of hash/code it is.

There is another post for this challenge by deadstopp that has some great hints in it. I think it will get you on the right track.

I checked it and it doesnt have any good hint about decryption they are talking about some of tools which i dont know…

Yes, they are talking about a tool and a vulnerability. If you have the cookie you should have what you need to proceed. Look up a tool that is being hinted to by likwidsec in that post. It would be difficult to give you any more information without giving the solution away.

I know what vulnerability to exploit for iknowmag1k, I know what tool to use, and, in fact, I even got some of the information I need. However, the tool I am using keeps timing out. Sometimes it times out right at the beginning and sometimes it gets further in the process before timing out. I can’t figure out why it times out and I can’t figure out how to fix this. It’s quite annoying when I am trying to encode something and it times out halfway through. The following is my output with spoiler info redacted. Has anyone run into this issue or ever heard of it? I can PM you the command I used to avoid posting it out here for everyone. Thanks!

Not entirely sure what was going on yesterday, however, I ran the tool this morning and it ran fine. Encoded what I needed to encode and got me to the flag.

@d00gman Any luck? I’m stuck there as well.

jackshd · May 3, 2018, 8:15am

@d00gman @kricket08 you don’t need to know the admin’s username for this challenge

ValleyCommando · May 7, 2018, 1:56pm

I’ve managed to update the cookie but I’m still receiving the same page when sending the updated request. Could someone point me in the right direction?

Thanks

ValleyCommando · May 7, 2018, 4:32pm

Got it resolved :-D. Very minor syntax error on my part (D’oh!)
