Capture The Flag Cyber Challenges
Challenge 1 - The fate of the world
World war II - The Germans are everywhere, always one step ahead of us. They are able to somehow hide their communications which gives them huge advantage in the battle. If we could somehow find a way to decipher their communication, we could win this war. We need help, and we need it ASAP.
Challenge 2 - Bob's final plan
Bob has been acting strange lately. His neighbors say that he stays up all night, laughing out loud from his basement, and that weird lights are coming out of his house. This leads me to believe that he is planning something evil. I could not find any more information about his doings since he will not talk to anyone, so I asked Eve to help me. Eve was able to infiltrate his network and to extract some files that may help us solve this mystery, and maybe to prevent a mess from happening, but those files seem unusual in their nature and we were not able to find out what they contain. Maybe you could help us.
Challenge 3 - Eve and friends
Someone hacked Eve's main site. Eve says she has no idea why anybody would like to target her, but in reality, the number of people that hate her is way too many to even count. The only way we can figure out who hacked her site is to investigate it closely. We already tried to do so but came up with nothing. We could really use the help of a professional here.
Challenge 4 - Let's catch them all
"I want to be the very best, Like no one ever was. To catch them is my real test, To train them is my cause! I will travel across the land, Searching far and wide. Each Pokemon to understand The power that's inside! Pokemon! Gotta catch them all! It's you and me, I know it's my destiny! Pokemon!"
Challenge 5 - Carol's mistake
Carol has asked me to help her with a technical problem she has. Apparently, while looking for a free Minecraft download, she accidently downloaded a malicious file containing a crypto-locker program. She has lost access to her important files and does not know what to do except crying, so I told her I will I help her. Well, I can’t ☹. Maybe you could help me, help her?
