A significant leak of personnel data has occurred at the U.S. Department of Homeland Security, exposing sensitive information about employees and agents who work for various agencies within the department. The leaked dataset contains user account records from Homeland Security's login system, including names, contact information such as work-issued phone numbers and email addresses, which is similar to what would be found on an employee's business card. The data was obtained by a hacker, with over 40,000 user account records compromised in the breach. Homeland Security has acknowledged the potential breach and is working to address it swiftly and effectively, according to a spokesperson for the department. The leaked data includes information about employees and agents from agencies such as Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE). The nonprofit transparency collective DDoSecrets has made the hacked data publicly available on its website, which is now being blocked by social network Bluesky after users reported that links to the site were marked as "malicious". Bluesky's decision to block links to the leaked DHS employee data has sparked a debate about transparency and censorship. Despite not commenting on the matter outside of U.S. West Coast business hours, a Bluesky spokesperson confirmed that the exposed data violates its community guidelines. However, rather than taking down the posts containing the link, Bluesky chose to block it altogether. The reasoning behind this decision remains unclear, but it has raised questions about the social network's commitment to transparency and open discussion. DDoSecrets co-founder Emma Best argued that while Bluesky's terms of service prohibit sharing home addresses and personal contact information, neither of these is present in the leaked dataset. Instead, the data contains professional contact information for government employees at a time when public interest in this type of information has never been higher. Best noted that requiring the public to provide such information for Freedom of Information Act requests can be a crucial step towards transparency and accountability. By making this information readily available, the government is inadvertently creating a valuable resource for those seeking to engage with transparency channels. As a result of Bluesky's block, several websites hosting searchable copies of the stolen data have been affected. A website hosting one such copy was taken down by its domain registrar, while another search site made by journalist maia arson crimew can no longer load as of Thursday morning. The US Department of Homeland Security has taken steps to remove leaked employee data from the internet. A takedown notice was filed via ZeroFox, a security vendor authorized by the department until 2028 to seek removal of sensitive information from online platforms. The notice specifically requests that domain registrars stop serving the personal contact and location details of individuals who did not consent to their publication. CentralNic, which hosts the affected domain name, has so far declined to comment on the takedown or whether it was prompted by a government demand. ZeroFox itself also remains silent on the matter, having failed to respond to questions about the takedown notice. As the controversy surrounding the leaked DHS employee data continues to unfold, Bluesky has taken swift action by blocking links to the sensitive information on its platform. The move is in response to government efforts to remove the links from various online platforms, with multiple takedown notices issued so far. However, ZeroFox itself remains silent on the matter, having failed to respond to questions about the takedown notice. In a bid to protect users and prevent further dissemination of the sensitive data, Bluesky has taken proactive measures to limit access to the linked content. --- Source: [TechCrunch](https://techcrunch.com/2026/10/29/bluesky-blocks-links-to-leaked-dhs-employee-data-as-government-seeks-takedowns/) Published by Noti Group: https://noti.group/u-s-department-of-homeland-security-experiences-significant-data/
