I by chance got the passwords for my company network and i actually hate that IT guy working there. I previously had a worm that would block all the network access in server but i lost that and don't remember what's its name. It wasn't detectable and the only way to repair the server was to reinstall everything. Please help me find such a worm or any other so i can fuck up that network completely and it's not repairable. I have enough knowledge in computer so it won't be difficult for me to understand your answers.
Thank you

PS: I have passwords for everything but they can be reprogrammed (Switches, routers, firewalls, Bridges and APs)

So just to be clear this is ran from command line once and if you can get remote access to one of the target's systems then?
