Description
Thor has been staring at this for hours and he can't make any sense out of it, can you help him figure out what it is? thor.txt
Solution
thor.txt
is an xxd dump so just reverse it to get the binary: xxd -r thor.txt > thor.lz
.
- Check what the binary looks like:
1 2
| file thor.lz thor.lz: lzip compressed data, version: 1
|
- We'll need he lzip lib and utility to manage that:
apt-get install lzip
.
- Let's uncompress the archive:
lzip -d thor.lz
.
- Now we get an image:
1 2
| file thor thor: JPEG image data, JFIF standard 1.01, resolution (DPI), density 72x72, segment length 16, Exif Standard: [TIFF image data, little-endian, direntries=5, xresolution=74, yresolution=82, resolutionunit=2, software=GIMP 2.8.18], progressive, precision 8, 1600x680, frames 3
|
- Just display it:
display thor
.
