A group of hackers followed through on its threat to release sensitive details about FBI employees by publishing the contact information for more than 20,000 bureau workers Monday afternoon the day after it posted similar data concerning nearly 10,000 Department of Homeland Security employees.

Using the Twitter handle @DotGovs, the hackers triumphantly tweeted that they had released 20,000 FBI employees’ names, titles, phone numbers, emails and countries, including the hashtag #FreePalestine in their message. They claimed to have obtained the information after hacking into the Department of Justice’s database, and the hackers taunted the U.S. government by stating that they would not cease leaking the information until the U.S. government cuts off its ties with Israel, according to CNN.

“FBI and DHS info is dropped and that’s all we came to do, so now its time to go, bye folks! #FreePalestine,” the hackers tweeted. “Well folks, it looks like @TheJusticeDept has finally realized their computer has been breached after 1 week.”

The Department of Justice is in the midst of investigating the hacks, and Department spokesman Peter Carr told CNN that there does not appear to be a breach of Social Security numbers and other private personnel information.

“The department is looking into the unauthorized access of a system operated by one of its components containing employee contact information,” Carr told CNN. “This unauthorized access is still under investigation; however, there is no indication at this time that there is any breach of sensitive personally identifiable information. The department takes this very seriously and is continuing to deploy protection and defensive measures to safeguard information. Any activity that is determined to be criminal in nature will be referred to law enforcement for investigation.”

The hackers also claim to have downloaded 200GB of data from the FBI and Department of Homeland Security, including credit card numbers and military emails, according to the Telegraph.

The group stated on Twitter that it took action to promote the Free Palestine movement and to press the U.S. government to cut ties with Israel.
