The U.S. nuclear weapons agency and at least three states were hacked as part of a suspected Russian cyber-attack that struck a number of federal government agencies, according to people with knowledge of the matter, indicating widening reach of one of the biggest cybersecurity breaches in recent memory. Microsoft said that its systems were also exposed as part of the attack.
