| 1 | File: MALWARE000 - I've used this new encryption I heard about online for my warez; I bet you can't extract the flag! | 100 | 36 | ||||||||||||
| 2 | File: Just some JS - Check out what I can do! | 100 | 38 | ||||||||||||
| 3 | File: This is not JS - I'm tired of Javascript. Luckily, I found the grand-daddy of that lame last language! | 150 | 32 | ||||||||||||
| 4 | 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 | 175 | 18 | ||||||||||||
| 5 | File: MALWARE101 - Apparently, my encryption isn't so secure. I've got a new way of hiding my flags! | 400 | 22 | ||||||||||||
| 6 | 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! | 550 | 16 | ||||||||||||
