Look at RIT in greater Rochester NY. They have a tight co op relationship with the NSA in Maryland, which hires 20,000 math/CS/cybersecurity experts.

The answer is YES, some schools pay attention to contests in hacking and also pay attention to FIRST robotics Dean List Winners and other national prizes. If your son can win a NATIONAL hacking contest it may help.
While this may not be a fit for your son, wait and see his grades and test scores, and try not to be so negative
about his potential, boys do get more mature with time!
MIT for certain gets information about students who get onto the national Deans list for FIRST robotics,
and they have an active admissions officer, who recruits Math Olympiad winners, thats the top sixteen math students
in the USA and looks for other national prize winners and may actually contact them because of those skills.
CMU also actively recruits math students, if they want to major in mathematics and not computer science.
Any national contest is actively TRACKED by some very selective schools out there. Tends to be schools like mIT
which have a relatively large Admissions team and can assign one person to recruit academic superstars.
But, a national prize is no guarantee for admission to MIT, or CMU, but note that CMU offers a special MERIT based
award for math students, that major in MATH not computer science or cybersecurity. They need to have demonstrated math skills such as very high AMC 10/12 score followed by AIME Exam or ARML team results
or math olympiad results.
Look into math exams, Colorado students can find and take AMC 10 and AMC 12 over much of the front range in
Colorado. There is a cutoff score to then sit for the AIME. These are national math exams that lead to a place
on a mathematics team.
There are computer related contests too and eventually they will get noticed, they are newer than the very established mathematics exams in the USA.
