The Legal Aid Agency (LAA), an executive agency of the UK's Ministry of Justice that oversees the Public Defender Service, initially disclosed the cyberattack in early May 2025, warning that payment information for legal aid providers might have been compromised. Two weeks later, it confirmed the breach was more serious than first believed, with attackers stealing a large trove of sensitive applicant and recipient data from 2010 onward, including contact details, dates of birth, national ID numbers, criminal history, employment status, and financial contribution details.
In an update published this week, the LAA said follow-up analysis found that stolen records go back almost five decades. "The vast majority of the LAA data relates to applications, claims or payments submitted to the LAA between January 2007 and 16 May 2025, or to cases that were live during this period. However, we have now confirmed that approximately 250,000 records predate 2007," the agency said. "The overwhelming majority of these are from the 1990s and 2000s, with only a fractionally small number dating from before 1990. The earliest record currently verified dates from 1978."
The agency noted that records predating 2007 do not mean everyone who received or applied for legal aid before that year was affected. Threat actors also stole legal aid providers' data, including contracts, office locations, financial information, and LAA Online Portal credentials.
A Ministry of Justice spokesperson told BleepingComputer: "We recognise that incidents of this nature are concerning for anyone affected. That is why we published information on GOV.UK as quickly as possible and have continued to update it as our understanding of the cyber-attack has developed." The agency said it had already committed £20 million to stabilising and upgrading the LAA's digital systems before the attack, and is now investing more than £200 million in modernising digital services and strengthening cybersecurity across legal aid services. The spokesperson added that there is currently no evidence that any stolen personal data has been published.
