Data Breach Exposes Personal Information of Hundreds of Philadelphia DHS Staff
A hacking group leaked files belonging to roughly 41,000 Department of Homeland Security personnel nationwide, including nearly 300 employees based in Philadelphia.
A recent cyberattack targeting the United States Department of Homeland Security has compromised the personal information of nearly 300 Philadelphia-based federal employees. The breach affected approximately 41,000 agents, operatives, and other staff members nationwide, which accounts for about one-fifth of the entire agency.
A hacktivist group calling itself the Department of Peace claimed responsibility for the data theft. According to a statement issued by the group, the cyberattack was carried out in retaliation for aggressive enforcement activities by Immigration and Customs Enforcement under the administration.
The statement referenced remarks made by leadership, noting that the hacking group targeted the agency in direct response to increased enforcement pressures. The compromised files were published online by the website Distributed Denial of Secrets through a database named Icepick.
Locally, the leaked data impacts 483 Pennsylvania-based Department of Homeland Security staffers, with approximately 285 individuals working directly out of Philadelphia. The affected personnel include 41 deportation officers and other staff members assigned to a Philadelphia field office, alongside employees from Mount Laurel facilities.
The exposed files contain sensitive details such as professional email addresses and cellular phone numbers for thousands of Immigration and Customs Enforcement staff. Furthermore, the leaked documents purportedly reveal internal organizational structures across several federal agencies.
In addition to Immigration and Customs Enforcement and U.S. Citizenship and Immigration Services, the breach impacts local personnel from Customs and Border Protection, the Cybersecurity and Infrastructure Security Agency, the Federal Protective Service, and Homeland Security Investigations.
A Department of Homeland Security spokesperson released a statement acknowledging the incident. The agency stated that officials were aware of a potential security breach and were actively working to address the situation swiftly and effectively.
The organization responsible for publishing the database, Distributed Denial of Secrets, previously released records from other high-profile hacks. Those past incidents included membership rolls linked to the Oath Keepers, a right-wing organization with thousands of current or former military and law enforcement members.
