Hacker Leaks Data from Jones Day Law Firm

February 18, 2021

Motherboard writers Jason Koebler, Joseph Cox and Lorenzo Franceschi-Bicchierai reported that Jones Day, one of the largest law firms in the world, was breached by hackers. Jones Day has recently been in the news as it was one of the law firms that represented the Donald Trump campaign in the challenges made to the 2020 election. The trio write “[the] hackers who run the Cl0p ransomware recently posted several gigabytes of data on a dark web site where they advertise their breaches.” If you are interested in the original site where the breach was first reported, it can be found here.

Jones Day apparently did not immediately respond to Motherboard’s request for comment; however, the Motherboard writers state “but confirmed the hack happened in a statement to The Wall Street Journal.” Jones Day has blamed the data breach on Accellion. Accellion provides file sharing systems and they were also victims of a recent hack. Information about the hack can be found here. Accellion is currently conducting an assessment of the breach and is using “an industry-leading cybersecurity forensics firm” to assist them, Motherboard reports.

There are apparently 20 caches available relating to the data breach at Jones Day, and they range from 1.5GB to 4.5GB. The original post from DataBreaches.net indicates that the hackers uploaded the data that was exfiltrated because the firm did not respond to their demands and threats.
