    I have tried GIMP and adding and removing filters is this the right track to get flag?

  • anyone have issues submitting the flag? Me and a collegue both solved it and got the same outcome, he got it submitted, i get incorrect notice. Exact the same format of input...

  • Nice challenge, I got stuck for a few hours after getting the original file out thinking there was no obvious indicator where to go and what a password may be.

    If I missed something "in the corners" can someone PM Me to say what :) I tried the usual ways in Gimp as well to try and reveal data and saw nothing so I assumed data was hidden another way, and I was blindly trying "obvious" passwords and one worked to give me the final stage to work on.

  • I am new here. As u guys mentioned about image, but i only received the hawking directory

    I have found the secret flag, but when I go and submit it, I just can't, it says that the flag is wrong. The fact that the flag has the format that HackTheBox is asking and also that it makes sense (I mean the text of the actual flag) makes it super weird that I cannot submit it !? I even typed the actual flag with my keyboard, but no dice. Any ideas ?

    EDIT: I found the solution. One of the programs that I used to crack the password at some point, made some of the flag's uppercase letters lowercase. If you have the same problem (like me and the guy a few comments above), then check this one.

    Would you please assist? I may have the same issue. I got something that is in the HTB format, but site says it is wrong., I have tried decoding it using different methods, to no avail.

    If you found something in the HTB format (e.g HTB{your_flag_here}) that means that you found the encoding; now, the only thing you need to do, is search for an alternative tool to decode it. Just google an other online decoder and you will be golden. What you are looking for, is in the first page of the google results.
