3DSCTF2017 - Bit Map
We’re developing our own security measures so no one will be ever able to execute our sensitive files.
We are given a link that contains a bunch of colored rectangles
We examine the source code we have an html table with hex colors, googling the first hex value (7F454C46) we found that is a signature of an executable linux file
- We concluded that there is a hidden ELF inside colors, so we wrote a python script to extract these color values and save them in a file
- The command file gave that its an ELF, we just need to run it and get the flag
