Iron Man has been hacked several times.
I think the last time was by the Skrull Empire of the Andromeda Galaxy, and they did work on the hack for years, plant agents who could pass as human including a fake for The Astonishing Ant-Man - so it was a really sustained attack. But he's also been taken by the armour itself when it became sentient due to a really bad Y2K bug, by Amadeus Cho, the teenaged sixth or seventh smartest person on the planet, using electromagnetic pulse, and for years Tony Stark was secretly an agent of Kang the Conqueror, Lord of the Fortieth Century. At least he quit drinking, except for Ultimate Universe Iron Man.
Stil, you should ask your board whether they really want to entrust their data to this guy. I mean, that's crazy talk.
