    if you get any thing drop a hint ;)

  • have you guys managed to move forward with it?

  • for me .... nop i got nothing

  • Can anyone offer a hint/point in right direction?

  • Top left ....
  • Top left translates to trolled - not very helpful. I tried strings, binwalk, steghide, xxd, exiftool, ELA, clone detection, LG, noise analysis, even tried the hex color codes hoping they will give me some hash (too long for md5 but was worth the shot). Hit the brick wall so hoping for any kind of suggestion on what to try next...


  • It's hard to give a hint without spoiling this one, but if you read a few stego CTF write-ups you'll eventually find one that is similar.

  • you dont need fancy tools for this one. read the tip again and think what could be meant with it

  • Anyone able to give me some help with this one? I've got some long repetitive strings but they don't seem to help

  • I am stuck here as well, any hints besides the upper left? Not sure how to take "last 2 digits." hint?

  • I'll DM you

    any hint...I've been staring at this for 3 days and nothing pops in my head..

  • @Sandel I'll DM you

  • I thought I understood what "last 2 digits" meant, but I've tried tools for what I thought it was and it didn't work

  • @jackshd Thanks man :) I used GIMP but still can't figure out what to do with the stuff I've got now...

  • I tried putting the digits I got as the flag but it was invalid :(

  • convert the result ;-)

  • Anyone can PM me regarding this challenge? Only thing i found thusfar is the binary data in the top left, but it's not brining me further..

  • Would also appreciate a PM with some hints... got trolled already ;)
    Tried GIMP, but obviously without success...

  • u know what, ending up being trolled is already bad enough, but ending up not even having the right answer makes this worse -_-

    So, you need to check the colors. Forget about the top left. Don't use any tools besides Gimp. again check a property of the colors you see on the image. Then remember the last 2 digits! Convert!

    Got it! . Need to think simple :D

  • What exactly am I supposed to do in gimp? So many functions there..

  • I cannot believe it , I was way overthinking it. I also got "trolled" :)

  • The flag didn't look like a normal flag, lost much time because of that weirdness

  • So much Overthinking....... Just need to read the description :open_mouth:

  • Hey guys, if anyone can give a hint. I have did everything with colors, so decoded and so on... but don't have any idea what to do next. Please dm me with a hint. Would be grateful
