A significant breach of computer systems at the Office of Personnel Management (OPM) has just been reported. Although the breach happened sometime in December of 2014, the breach was only discovered in April according to officials, as a result of new tools implemented by OPM. Over 4 million current and former federal employees are being notified that their personal data may have been compromised.
Who was behind the attack has still to be confirmed, however the Washington Post is reporting that the attackers might be from China.
Given that the OPM hold sensitive data about federal employees the ramifications of this breach could prove to be significant.
