Chinese hackers breached a US Navy contractor in January and February, stealing information on naval technologies, weapons, and plans. While government officials have said all compromised data was unclassified, the breach underscores ongoing difficulties with contractors and agencies concerning the protection of sensitive data. The most significant breach in recent times is most likely that of the Office of Personnel Management that leaked information on 25 million federal employees and contractors, and was also perpetrated by hackers connected to the Chinese government.
