America's nuclear power plants use passwords like '1234'

The only thing preventing a possible nuclear reactor meltdown could be the password "1234," according to a new global study of power plant security systems, theFinancial Times reports. Hacking into a power plant's computers could allow a malicious individual to tamper with cooling systems and back-ups to induce a nuclear meltdown. While the risk of damage is exponentially high in the case of a hack, new research has found that nuclear facilities have few measures in place to prevent a destructive cyber attack.
