I found an interesting site today: when you open it, it just says "knock, knock, neo_" and lets you enter a command, i.e. 'redpill <string>'. By entering 'redpill', it tells you how to find the correct <string>, and by entering it your level increases. I am currently stuck on the second level: Spoiler: redpill confirmed level 2 bruteforce SHA224: fc6730bd5840d324b794eed7f14f40473a8a5dbb8e16805dc40b50bd Right now I am looking for possible answers, so could you guys tell me some matrix related words I could try? There is also a command 'hash <string>', so I can check if its correct.
