Shafi Ahmed is a pioneering surgeon who was treating patients in the NHS on the day the Wannacry computer hack brought hospitals to a standstill. Mahiben Maruthappu is the CEO of a tech company providing care to the elderly. And DawgyG is a hacker.
Is DawgyG a good hacker or a bad hacker? That depends who's asking the question.
