Data on more than 41,000 US Homeland Security workers leaked
Data on more than 41,000 DHS employees and contractors was posted online on Wednesday, including names, contact details and descriptions of their work.
The records cover the US Department of Homeland Security and several agencies, including Immigration and Customs Enforcement and Customs and Border Protection.
The hackers say they obtained the data through DHS’s Okta login service, which organizations use to control access to internal systems.
Okta says it has no evidence that its systems or data were compromised, and DHS had not immediately commented.
The leak reveals details about the department’s structure and operations, including staff involved in immigration enforcement and some undercover work.
The information could also help researchers make public-records requests, but the exposed personal and work details raise security concerns.
The data is available in a searchable online archive, and no further response or action from DHS was described.
A leak published on October 28 exposed records on more than 41,000 Department of Homeland Security employees and contractors.
The records include contact details, office locations, internal group memberships and information related to undercover and surveillance programs.
Distributed Denial of Secrets and researcher maia arson crimew said they obtained the data from a group calling itself the Department of Peace.
The group said the leak was a response to a promise by DHS Secretary Markwayne Mullin to step up Immigration and Customs Enforcement operations.
Okta said it had no evidence its data or systems were compromised, while DHS did not respond to requests for comment.

What people are saying
On July 17th, Markwayne Mullin said he was ’turning up the heat.’ This is what happens to ICE when you do that.
We are aware of this report. Okta is secure, and we have no evidence our data or systems were compromised.
I don't think we should let them scare us into not looking into them.
The leak is extraordinary but deceptive in [its] simplicity as it identifies the officials responsible for overseeing covert and undercover operations, the government’s hunt for leakers and the failed BlueLeaks investigation — along with key personnel in DHS’s ever-escalating rendition and deportation programs.
