Hacking is fine the way it is right now, but I did have an idea to make it more like actual hacking.
My idea is to either change the coding of the game slightly or to add another module to the game.

This change in coding or module would provide an added bonus for the uses. The bonus is a potential for your hack to not be caught, because not every hacker is caught in time to track who that person is.

The percentage wouldn't be too high, perhaps 10 at most. And it would also be based off of stats as well. I was thinking that if your scan is within 10-20% of their cloak and your cloak is within 10-20% (perhaps more towards 15-30%) of their scan, there would be no chance of not being caught.
My current thought is that it would add a new roll to the hacking attempt, so essentially two new possibilities (Though the aesthetics for all of the hacks would have to change), which probably look a little something like this:

Hack Successful. You steal XXX Research Points from the enemy database, however, you were caught before you got out.

Hack Successful. You steal XXX Research Points from the enemy database, and you were able to sneak out before you were caught.

Hack Successful. You didn't manage to find anything useful, and you were [not] able to get out before you were caught.

I think you get the idea with the outcomes.

I hope this could make hacking in this game closer to actual hacking.

And when someones hacks you, and they succeed in getting away without being caught, it would appear in your log as

Someone hacked you and stole XXX research points.

+1! Even better if you someone steel a planet

Not bad, I like it!

+1 Its one of the first properly balanced ideas like this its not game breaking but it gives you a chance to be a proper hacker the current system is flawed.

+1. The only thing that I would recommend is either a massive boost to the chances of not being caught when you get: "Hack Successful. You didn't manage to find anything useful, and you were [not] able to get out before you were caught. " Or, keep that part like it is now, where if you find only a blue badge your hack goes unnoticed excepting when they have a firewall trap on.

+1 I really like this. Especially if you can score a critical hack on a nice planet.

Perhaps the numbers could be more balanced.

Another idea I just had (this would probably break the idea's balance)
but perhaps put a little bit hacking skill into the chance.
i.e. Your successful hacks vs. theirs, using the knowledge of the best way to stop a hacker is to hire an equally skilled hacker

Just thought of this today, so now I have a reason to post...

It should also be based on the amount of hacks performed on the player in the past 24 hours.

As in, the more you hack someone, the more likely they are to wise up to your schemes and catch you.

+1 i love the idea.
