    I'm struck after matrioshka4 . I have the gpg encrypted file but how to get the password to decrypt it.

  • I got the fake flag, any tips on how to proceed with gpg encrypted.

  • I'm stuck in layer 4, I already got all strings from that file, but I dont know that to do, I tried to convert it to ASCII and more, but nothing. Any hint?

    I spent most of my time on this challenge thinking I was missing something, but it turned out to be a hard-to-diagnose issue with gpg.

    Bottom line, careful about gpg decrypt after su! For more info: https://lists.gnupg.org/pipermail/gnupg-users/2009-May/036544.html

    Hope this helps pull someone else up from the rabbit hole...

  • Ive got the HTB{fake flag} from m4, however i am lost after this, could someone please DM me a hint, my head hurts :)

  • Hey I solved the challenge but I had to extract the huge data, could anyone tell me how to do it without the extraction part? Thanks :D

  • I am stuck at matrioshka1. I have files with Hex-values and matrioshka1. But if I binwalk the files with -dd of -e I keep getting matrioshka1. Which is 210 bytes.

    ..what else does binwalk report that the file contain beside the image itself?
    If your tools insist on selecting the wrong thing, why not rip it out?

  • I have found the flag! It was a loooong journey!! But.. as always with HTB, it as worth it.

    Guys, I didn't understand, which tool did you use to extract the zip file from the image? I'm new to forensics in pictures.
    Binwalk?

    Is someone available for a DM hint? At matrioshka4 and trying to figure out the hex.

    Nevermind... Helps to try harder...

  • If you're stuck on strings, remember there's a default for the number of characters per line it returns, and that number can be modified. Man page has more info 😁
  • great challenge! thanks!!
