Hackcon CTF’19 – Too cold for steg Writeup

tl;dr

Whitespace steganography

Description

Initial Analysis

Got a text file and opening the text file in any text editor and selecting all the text we can find some whitespace present at the ending of the each each line.

As the title is Too cold to steg we will get a tool known as stegsnow in our mind.

But for using the stegsnow we need a password. After searching for the password in the file given we can get the password as d4rkc0de-IIITD.

grep password

Then using the stegsnow we will get the flag.

stegsnow command

Flag

Flag: d4rk{h@ving_fun_w1th_st3gsn0w?}c0de
