Details of more than 41,000 Department of Homeland Security employees and contractors, including names, work email addresses, phone numbers and office locations, were published on Wednesday by the transparency group Distributed Denial of Secrets as an archive called "Icepick," WIRED and the BBC report. The groups say the data came from a hacking group calling itself the Department of Peace, via DHS's Okta single sign-on; Okta told WIRED it has no evidence its systems were compromised. WIRED says the records include undercover and surveillance programs; DHS said it is "aware of a potential breach."

The r/technology thread (WIRED) drew about 46,500 upvotes in an 18-million-member community and the r/news thread (BBC) about 43,600 in a 29.5-million-member one. Many top replies cheer the leak, quoting the hackers' note that "they have our information, so it's only fair that we have theirs"; others argue that names and work contacts of public employees should be public anyway, and some question why undercover immigration agents are needed.
