For slackblock-steg pay very close attention to what images the tool will accept to add a message to. Once you figure out what property images need to have, you should have a much better idea of how/where data is being hidden. #BSidesSF #CTF

The acaan challenge is supposed to help prepare you for drago-daction.
drago-daction has a vulnerability that gives you a "write any data to any file at any offset" primitive, and once you're there they're the same solution. #BSidesSF #CTF
