Uncompress the challenge (pass: cyberdefenders.org)
RE101 challenge is a binary analysis exercise - a task security analysts do to understand how a specific malware works and extract possible intel.
File: MALWARE000 - I've used this new encryption I heard about online for my warez; I bet you can't extract the flag!
File: Just some JS - Check out what I can do!
File: Unzip Me - I zipped flag.txt and encrypted it with the password "password", but I think the header got messed up... You can have the flag if you fix the file
File: MALWARE101 - Apparently, my encryption isn't so secure. I've got a new way of hiding my flags!
File: MALWARE201 - Ugh... I guess I'll just roll my own encryption. I'm not too good at math, but it looks good to me!
