A contractor for US national laboratories and a radioactive waste storage site managed by the Department of Energy were among the victims of wide-ranging cyberattack that saw several federal agencies hacked, according to a person familiar with the matter.

A department spokesperson confirmed Thursday that records from two of the agency’s “entities were compromised,” though further details on the extent of the breach couldn’t immediately be determined. Multiple US agencies were compromised by a hacking campaign in which attackers exploited flaws in a popular software tool to gather information from a range of victims.
