According to BBC, Best said, "The leak is extraordinary but deceptive in it's 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".

BBC reports that details of more than 41,000 personnel working for the US Department of Homeland Security (DHS), including thousands involved in immigration enforcement, have been leaked to the public. The identities of over 41,000 officials from the Department of Homeland Security have allegedly been exposed in a massive data breach by a hacktivist group calling itself the Department of Peace, CNBC reports. A hacking group cracked the US Department of Homeland Security's personnel files, exposing the names, phone numbers and addresses of more than 40,000 DHS agents, operatives, and associates, on October 28, including those involved in undercover operations, NPR reports.

The Department of Peace also shared the trove of data with Ryan Ottignon, a US-based journalist, and a Swiss hacker known as maia arson crimew, NPR reports. According to The Guardian, in a statement, Emma Best, a Distributed Denial of Secrets co-founder, said the hacktivist known as “maia arson crimew” developed a search tool for the data that would allow the public to browse it. DHS completed 980,000 deportations in the first 18 months of his term, according to the Migration Policy Institute, CNBC reports. Since President Donald Trump returned to office in 2025, the US has enacted nearly 1 million deportations, according to data from the Migration Policy Institute, BBC reports.

According to The Guardian, Okta said, “Okta is secure, and we have no evidence our data or systems were compromised.”
