Jones Day said hackers breached the law firm and accessed the files of 10 clients, Bloomberg Law reports. A prolific cybercriminal group known as Silent took credit for the attack, listing Jones Day among its victims on an extortion website. “Jones Day recently experienced a cyber ‘phishing’ incident in which an unauthorized third party accessed a limited number of dated files for 10 clients,” a spokesperson said in a statement. “All impacted clients have been notified.” The identities of the affected clients were not immediately clear. Silent specifically targets U.S. law firms, taking advantage of the “the highly sensitive nature of legal industry data,” according to a 2025 FBI alert. Jones Day was also hit by a cyberattack in 2021.
