A major cyberattack in the United Kingdom has exposed the names and contact details of nearly 100,000 police officers on the dark web, according to a report published on August 3, 2026. Hackers allegedly infiltrated a key law-enforcement database and obtained sensitive information, raising serious concerns over the personal safety of officers involved in crime-fighting work over many years.

British media reported that the attackers targeted the Police National Legal Database, an online system used by police forces across the UK for routine administrative work and legal support. Following an initial investigation, police believe a cybercrime group called ExfilSquad may be behind the breach. Investigators view the incident as part of a series of recent cyberattacks against Western government and strategic institutions.

A police officer whose name appeared on the leaked list said exposure of sensitive details had put the officer and colleagues at extreme risk after work against dangerous organised criminal groups. Authorities fear the number affected could rise, as most officers in England and Wales use the database during their careers. About 145,000 full-time police officers currently serve in the two regions. Authorities have begun a high-level investigation and taken urgent steps to strengthen cybersecurity.
