Hack the Box Challenge - Blackhole
It looks like HTB has added a few new Miscellaneous challenges since my last post, time to get back to work! First on my list is Blackhole, a 20 point challenge with a hint of "A strange file has been discovered in Stephen Hawking's computer. Can you discover what it is?" Let's get started! I use wget to download the zip file, then unzip to extract it. After I enter the password, it looks like there's another archive in here, let's try to extract that one as well. Well, according the file manager, it has the folder icon, but when I run the file hawking command, it appears to be a jpeg - let's rename it and see what happens. Using the rename command, mv hawking hawking.jpg changes the extension to a jpeg. Now I can see a picture of Stephen Hawking with a nice quote, "Life would be tragic if it weren't funny." This is probably going to be a stego challenge, awesome! I'll use steghide like I did in the Milkshake challenge,
