WebP: Идеальный хамелеон? Разбор формата и LSB-стеганография в режиме Lossless
Всем привет! Мы продолжаем наш цикл статей, посвященный практической стеганографии в самых, казалось бы, обыденных файлах. Мы уже научились прятать данные в «слепых зонах» документов MS Office, внедрять «файлы-призраки» в EPUB и даже создавать скрытые каналы данных внутри PDF. В комментариях к прошлым материалам наши читатели справедливо заметили: « А что насчет WebP? ».

We think we’re finally done with everything we had to get done before concrete. The Glavel is in and compacted, the filter fabric is laid on top, and the Stego radon barrier is installed under the building slab. Every one of the 22 (!) conduits and pipes has been meticulously sealed with mastic.
Tomorrow morning our concrete contractor will form for the two slabs and add rebar, and concrete for the first slab is due at 10am. Fingers crossed!

We’ve been making good progress on the build. All that’s left to do before concrete can be poured is install filter fabric and our radon barrier (15-mil Stego). But, rain has stopped play today and the concrete contractor is coming Tuesday so Monday is going to be busy!
On Friday we bought a rock bucket for the tractor which is a game changer for getting big rocks out of our soil before we backfilled.

Some basics for Image Steganography in Linux:
file:
Running the 'file' command to see the Image's type. For instance you could be given a .jpeg file but after running 'file' command you could see its a PNG.exiftool:
Using the 'exiftool' to see the metadata, like checking the size of the image to see its sensical or its too large, there could be location tags and other clues.strings:
Running the 'strings' command to see if there are plaintext extractable charactershexdump:
With 'hexdump' you will see the hex format of the file. For instance the first few bytes will tell you the type of file. or searching for the 'FE' marker what comes after 'FE' is a comment on the file.
You could also use the 'xxd' command.binwalk:
'binwalk' will show if there are any embedded files. and if there are you can extract them with 'binwalk -e <filename>'.steghide:
Steghide is a steganography program that hides data in various kinds of image and audio files. It also extracts hidden data.
to extract hidden data run: 'steghide --extract -sf <filename>'
some files will need you to provide a passphrase in order to extract hidden data.for more tips on stego this is an interesting page:
