Description

On June 16, 2021, UK-based law firm Gateley Holdings Plc disclosed a cyber security incident through a filing with the London Stock Exchange. The firm confirmed unauthorized access to its systems resulted in a data breach, though specific technical details regarding the attack vector or intrusion method were not publicly released. Gateley's incident response team swiftly identified and isolated the compromised data, which had been downloaded to an external location. The firm executed deletion of this data from the unauthorized repository and stated no evidence existed at the time to suggest further dissemination of the stolen information. Immediate containment actions focused on securing systems and preventing additional exfiltration.

The breached data included confidential client information, though Gateley characterized the scope as affecting only a "very small percentage" of its total data holdings. The firm deferred direct client notifications pending completion of internal investigations to verify the exact nature and extent of compromised records. No operational disruptions or system downtime were reported in conjunction with the incident. Gateley's disclosure emphasized procedural adherence through regulatory channels without specifying whether law enforcement was engaged. The filing did not address potential financial repercussions, forensic findings regarding attacker identity, or confirmation of data deletion methodologies employed.
