Law Firm Jones Day Hit with Ransomware Attack, Third-Party Accellion Software Blamed

One of the largest and highest-grossing international law firms, Jones Day, suffered a massive data breach at the hands of the Cl0p ransomware collective. At least 20 compressed caches of confidential data stolen from the Cleveland-based law firm—which recently served as counsel to former President Donald Trump—were leaked on the dark web. The cache sizes range from 1.5GB to 4.5GB and include highly sensitive email communications from employees at the firm.
