ZeroNights hackquest is a hacking challenge before annual
ZeroNights conference where the goal is to solve tasks related to
information security (reverse engineering, web, mobile hacking,
penetration testing and more).
The winners receive free invitation to the conference and a place in our Hall of Fame.
Your boss catched crypto locker. Sysadmins were able to restore all files from backup - except one (which is very important for him). Your goal is to restore this file.
К твоему боссу на компьютер попал криптолокер. Админы смогли восстановить все его файлы из бекапов, кроме одного, очень важного для него. Воcстанови файл и помоги своему боссу (или накажи за все его грехи, ведь файл, похоже, относится к черной бухгалтерии).

Recently we’ve revealed a bunch of Trojans used by the hacker group “0n3 @n07her BearS”. Nevertheless, some big companies deny the fact of their existence. We've learned that the servers of the company "Horns and Hooves" were infected with one of the Trojans. Help us to get the flag to prove its CEO the threat is real.
Trojan sample: server
Server address: 220.127.116.11

Do not come back empty-handed! Bring. Us. Intel!
Your friend wrote an algorithm for generating licenses and asked you to test it. He promised a beer and pizza if you will find a way to crack it. Prove to him that his algorithm is no good.

Hey, there is a person in Moscow who keeps his important password on his Android phone. Sounds weird, we know.
It turns out that he is using some program for managing his data called Packer
We performed MITM attack on his phone during application-to-server synchronization and got database file named `packs.db`. But it looks like important data are kept encrypted there. So get your task: decrypt the data and give us the password!
You are a super fucking amazingly gorgeous sexy and beautiful girl, but you cannot accept it and dream to be a bag of bones. That's the reason why you need hack this site and to know The Secret!
