What programing language would it be the easyest to do a dokkabei like "hack" in

[hunkrekker]

So, I would like to write a code like the one Dokkabei uses in RainbowSixSiege ,but I want to install itself in the background without permission but only I would have to send it to them becouse I don't want to write a virus that could spread on it's own.

That would be in whatever language you already know.

And..."install itself in the background without permission"...
...you can't do that.

The OS and any antivirus specifically look for things like this.
