Federal employees are being targeted by multiple phishing campaigns posing as identity-theft prevention services in the latest fallout from the largest government data breach in U.S. history.

The U.S. Computer Emergency Readiness Team (US-CERT) warned federal employees about the attacks in an alert posted on Tuesday.

Hackers infiltrated the Office of Personnel Management (OPM), the government’s HR agency, and rifled through its systems for more than a year, compromising the records of as many as 18 million federal employees, including FBI agents and members of the military.

Anonymous government officials have told the press that the attack was the work of Chinese hackers, but the Obama administration has yet to officially accuse Beijing of responsibility.

A phishing attack involves a malevolent actor posing as a legitimate entity—in this case, OPM or the identity-protection firm CSID—in an attempt to lure a user into giving up personal information. The message is intended to look as legitimate as possible, and many people have fallen for phishing emails and unknowingly handed over their information to hackers.

In addition to requesting specific information, phishing emails also ask users to visit websites laden with malicious code that infects the user’s computer. The malware can then steal documents, capture keystrokes like passwords, or use the computer to distribute more malware in what is known as a botnet.

US-CERT asked federal employees who received suspicious messages to report them to the team.
