Jones Day, a major law firm, confirmed a cyber attack that compromised files related to 10 client matters. The breach is attributed to the Silent Ransom Group, which has been targeting law firms using phishing tactics. Hackers accessed dated files and have claimed responsibility, publishing a file directory and screenshots of negotiations with the firm. All affected clients have been notified, but specific details about the files or clients remain undisclosed. This incident follows a recent trend of cyber attacks on law firms, highlighting vulnerabilities in their cybersecurity measures.
