A company working on behalf of the Department of Homeland Security sought to cut off online access to information on more than 41,000 employees that hacktivists said they obtained from a database breached at DHS.

A search tool for the database, named Icepick, went offline for a spell before coming online again Thursday under a different registrar.

Icelandic hosting company FlokiNET said Thursday that it received a request from DHS contractor ZeroFox to remove the data, which it refused.

“By mid-morning, icepi.cx no longer resolved. Its registrar, CentralNic, had placed the domain on serverHold,” FlokiNET said in a blog post. “Our refusal kept nothing online. The request that decided the outcome to take the site down was not the one sent to us. A registrar reached the opposite conclusion the same morning, published nothing, and a global audience lost access to the site. In the meantime the site is online again under a domain from a different registrar.”

CentralNic and ZeroFox did not immediately respond to requests for comment Thursday.

DHS said late Wednesday that it was working to protect its employees against any breach.

“DHS is aware of a potential breach and is actively working to address the situation swiftly and effectively,” a spokesperson said. “We take all security threats against our employees and officers seriously and will work to ensure all are properly protected. We will update the public when more information is available.”

The social media site Bluesky was also blocking links to the archive because it shared people’s contact information without their permission, although a company official said changes were coming because the wording had identified it as a malicious link.

FlokiNET said it refused the ZeroFox request that mislabeled the archive as part of a doxxing campaign.

“Doxxing publishes private details about private people so that others can find them at home. Icepick publishes work identities of government employees,” it wrote. “Who they work for. What their role is. How they can be reached in that role. The information describes people in the exercise of public authority, not in their private lives. Federal officers carrying out an enforcement programme are not private individuals while they are carrying it out.”

“The public has a legitimate interest in knowing who is doing that work, under whose authority, and in which office,” it continued. “Journalists cannot report on an agency whose personnel are structurally unknowable.”

ZeroFox said that regardless of that, the data made it possible to locate people whose information was in the database.

“The request does not depend on who the listed individuals are or what their duties are,” ZeroFox wrote to FlokiNET. “It rests on two facts: the data was stolen, and it is personal data that identifies and locates real people.”
