Senseless Behaviour

The solution wasn’t hard. Just remember to try all tools you know on the files for this challenge!!! Thanks to @petelska for the help.

I tried many tools any hint will be very appreciate

How did you guys extract the data from the file?

The output from binwalk looks like false positives, steghide finds nothing, LSB encoding in both LE and BE format outputs garbage…

I got the file with random strings.I’m stuck here.Someone can give me any hints?

I need some hints, I’m stuck. First I got 4 files mysql compressed, then I tried different tools (soc, audacity, sonic visualizer) with no results.

firstly, you should use stegcracker tool for .wav file. And then you will get output file with base64 encoded

i got the file with random meaningless strings. I don’t know what am I supposed to do. Can anyone give me some hints on PM?

If you watch carefully, you’ll see these strings look like they are encoded!

Decode the strings, get the hex dump with the file extension pointed (when you’ll try to get ascii out of that), then convert the dump into the file. You’ll get an image, then use a stego tool and try all the filters until you see something extraordinary) Then apply the senseless system to decode it!

This. If you hadn’t have said this, I never would’ve known what to do. Not a big fan of challenges that require you to know about some obscure tool on github. That being said, at least now I know about that tool, so that’s cool I guess.

Overall, it was a fun challenge and good learning experience. Maybe he should’ve left a reference to stegcracker as a hint or something.

nevermind, got it

I’m stuck at last step, any help?

hope not spoiling to much… manual labor: www.dcode.fr search for the senseless language and use the dots…

Hey Can anyone help me with Challenge:senseless behavior(Stego) . The flag that I have is correct one. I have already asked others who have completed this challenge. But at the time of submitting the flag…it says wrong flag. Can Anyone help me with this.

try with lower cases…

Solved,

An interesting challenge, the clues of this thread were of great help, here mine:

Search the secret word of the file, it should be enough to start the challenge, after a while you will see a code, they are “magic numbers”, in linux there are ways to make the conversion, and after that you should look for something in that file: points, some humans understand it, but use their hands to understand it …

Really nice and difficult challenge! Sometimes too much information can blind you…

can someone tell me “*******bats” is flag?
sorry got it :happy:

Hi I used binwalk and got four MSQL ISAM files but seems to be the wrong direction, right? Any help is highly appreciated.
