#Hidden in Plain Sight

Primeiro, baixamos o binário
wget -c https://play.icec.tf/problem-static/828644c3ad8ccfa14b86a69dccd36f2b-plain_sight_df5d2c1da50110458fa00d0db6586b23cd67317c7f7b95f4a092d645a4570296 -Oplain-sight

Nem me dei ao trabalho de executá-lo. Já abri direto no gdb:

```
gdb plain-sight

(gdb) disas main

```

Bastava copiar esse trecho e colar num arquivo, nesse caso, chamado "file"

Então fazer essa função em bash:

```
hex2ascii(){
i=0
while (( $i <${#1} )); do
echo -en "\x${1:$i:2}" let i+=2; done echo; } ``` e por fim: ``` for i in$(grep mov file | cut -f3 -dx | cut -f1 -d,) ; do hex2ascii $i; done | tr -d '\n'
```
