You could try the Jeeebus three-step program that has a guaranteed 100% success ratio. It takes some work, but the payoff is well worth the effort.
1. Develop a meaningful and deep relationship with his parents. Go to the movies with them. Every Saturday for the next year make sure you have a game night, maybe Scrabble or Monopoly, where you're in their house at least half the time. You might want to purchase a boat if you can afford one and new sailing attire (does not matter if power or sail boat). Invite them out. Go fishing. Be the best friends you can. Important, however.... do not befriend the teenage kid. Remember, even though step 1 takes many years, do not lose sight of your ultimate goal.
2. Switch careers. For this plan to work, you need tremendous experience in banking and e-security. I recommend moving to Switzerland and taking an apprenticeship with one of the largest Swiss banks. You'll need to do drugs, lots of them. Hang out in seedy bars and solicit hand jobs from strangers. Eventually you'll meet an elite Swiss hacker that can finalize your training in manipulating sensitive computer and financial data.
3. You're finally ready. Stab the little shithead in the face with a screwdriver.
