Sony Pictures Entertainment has sent a letter to employees warning them that some personal health data belonging to SPE employees may also have been compromised in the attack that hit the company in late November. The attackers who have claimed credit for the Sony breach, who call themselves Guardians of Peace, have been leaking this information out over the course of the last few weeks. The company also is warning employees about the possibility of phishing attacks against them based on the public knowledge of the breach. Some of the personal health information and other data already has been published online.
