Summary
The US Department of Homeland Security has confirmed a significant cybersecurity breach after hackers successfully infiltrated multiple agency systems and published the personal data of more than 41,000 employees on a public website. The leaked information includes sensitive details about personnel involved in covert surveillance operations, undercover assignments, and intelligence work across several key homeland security divisions. The breach was first announced on Wednesday by the transparency organization Distributed Denial of Secrets (DDS), which obtained the data from a hacker collective calling itself the "Department of Peace." Reuters independently verified the authenticity of the leaked records and was able to contact three affected DHS employees directly through the exposed information. The exposed data includes names, telephone numbers, email addresses, job titles, email distribution groups, and specific operation names revealing which personnel were assigned to special operations, surveillance work, computer forensics, and undercover missions. DDS co-founder Emma Best stated that the leak exposes officials responsible for supervising secret operations, as well as those involved in the department's increasingly aggressive deportation and removal programs. The Department of Homeland Security issued a statement acknowledging awareness of the potential data exposure and affirming that active measures are being implemented to address the situation and protect employee information.
