“We have over 100 gigabytes of data,” the hacker wrote in response to an email from the Journal.
The hacker, in the Journal’s correspondence, said it first reached out to Jones Day management on Feb. 3 and informed the firm that its network had been hacked and that data had been stolen. As of Tuesday, the hacker said Jones Day management hasn’t responded but that it believes the law firm received its letters about the attack. The hacker said ransom negotiations haven’t begun.
Jones Day, in its statement, said it hasn’t been the subject of a ransomware attack. Rather, Jones Day said, it has been informed that a company the law firm used to transfer large files electronically, Accellion, “was recently compromised and information taken.” Jones Day said that Accellion is used by many law firms, companies and organizations.
