While the latest news about OPM's breach is worse than initially revealed, a new security report indicates cybercrime is big business for attackers who receive an estimated 1,425% ROI for malware schemes.

While investigating a cyberattack on the information of about 4 million federal employees, officials discovered "a separate intrusion into OPM systems that may have compromised information related to the background investigations of current, former, and prospective federal government employees, and other individuals for whom a federal background investigation was conducted," Samuel Schumach, OPM's press secretary, said.

Reports from Bloomberg and the Associated Press said hackers tapped into as many as 14 million personal records, a number OPM would not confirm, citing its continuing inquiry.
