I havent paid for it directly it came with the membership, they set up wargames for us to hack(we meaning members).It was filled with problems initially,they had the setup wrong and its been there for a long timeso theres not much action in that paticular thread.

I know thses things about my objective
It migh be a binary because it has no extension (./ filename) makes the client(my pc) stop responding.
I dont have any idea on how to open a ssh connection from a windows pc to a linux server
The file that i downloaded dosent have a extension so windows dosent have any program for Opening it in notepad is of no use nor any c compilers/debuggers.
Its not a virus/malicious software for sure
I feel that the community here is a lot more open to basic questions
I am stuck in this problem for the last 2 days ( that takes a lot of googling time )
