Hacker stole personnel data about thousands of Homeland Security employees, including CBP and ICE agents
Personally identifiable information belonging to thousands of U.S. Department of Homeland Security employees has been published online after a hacker stole reams of data in a previously undisclosed breach at the government department earlier this year.
The breach includes names, job titles, and work contact information, such as email addresses, cell phone numbers, and office locations, of more than 40,000 people who work for the federal department, including border and immigration agents, cybersecurity staffers, and senior department officials.
A hacker who goes by the handle Department of Peace claimed they obtained the data from an Okta single sign-on system used by Homeland Security to allow employees and contractors across its various agencies to log in to its central network. The Okta system also contains IT and log-in records associated with the employees’ user account, including details about which systems and internal apps they are permitted to access.
More than half of the dataset — some 21,000 records — relate to employees with U.S. Customs and Border Protection (CBP), who work at airports and other ports of entry.
The data also contains records associated with another 10,000 employees of Immigration and Customs Enforcement (ICE) and its Homeland Security Investigations (HSI) unit, and just under a 1,000 employees who work at U.S. cybersecurity defense agency CISA.
Thousands of additional records relate to staff who work at the department’s headquarters and its other agencies, including U.S. Citizenship and Immigration Services and the Federal Protective Service.
“They have our information, so it’s only fair that we have theirs,” said Department of Peace in a note left with the data, which TechCrunch has seen. The hacker did not respond to TechCrunch’s email requesting comment and with questions about how the breach was carried out.
This is the latest data breach to hit the U.S. government in recent months, following earlier hacks involving the theft of thousands of FBI agents’ personnel records and the personal information of millions of serving and former military service personnel from the Pentagon’s human resources unit. It’s also the second breach involving Homeland Security this year, after the same hacker claimed to have taken thousands of contracts between the department and the private sector, including defense contractors and surveillance vendors.
The latest batch of breached data, which appears authentic, offers a rare — albeit incomplete — view into the scale and operations of Homeland Security, whose deportations, arbitrary detentions, and killings of U.S. citizens under its leadership have become a key issue for voters ahead of the upcoming U.S. midterm elections.
The stolen Homeland Security data was provided to journalist and hacker maia arson crimew, who then shared a copy with DDoSecrets, a nonprofit collective that hosts leaked datasets in the public interest.
