Releasing the tool would not be risky at all. The only time you can get in trouble is if you include code/assets from the game. And at least in America, DRM circumvention is 100% legal, and the federal courts ruled that it is legal, and its also legal according to state governments too. Don't let people like IWesly or whoever to lie to you and ruin things for you. The whole crap where he claims you'll be sued is because they want an excuse as to not let anybody have his tool except for their friends, and they don't want anyone else to take the spotlight either.
