A hacker claims to have stolen files from the prominent law firm Jones Day, The Wall Street Journal reported on Tuesday.
The files were posted on the dark web, according to the Journal, and included several documents that were reviewed by the newspaper. One note was allegedly addressed to a judge and was marked as a “confidential mediation patent”, while another is a letter of intent for “confidential documents”.
The newspaper reported that it could not immediately confirm the authenticity of the documents.
The hacker told the newspaper that he first contacted the law firm on February 3 to inform him that his network had been hacked, but did not respond on Tuesday.
The Jones Day violation was first reported on the cybersecurity blog DataBreaches.net on February 13th.
A major international law firm, Jones Day has many high-quality clients and has represented former President Trump
Donald Trump, Democrat Dingell of Michigan, about violent rhetoric: “We had men in front of the house with assault weapons”administration and re-election campaign.
The company acknowledged to the newspaper that it had exposed data, but attributed it to another cyber attack on the Accellion FTA file transfer platform.
“Jones Day has been informed that Accellion’s FTA file transfer platform, which is a platform that Jones Day – like many law firms, companies and organizations – has recently used has been compromised and the information taken.” , said the law firm in a statement Bloomberg Law.
“Jones Day continues to investigate the breach and has been and will continue to be in discussions with affected customers and competent authorities,” the statement said.
The law firm did not immediately return a request for comment from The Hill.
Accelion revealed for the first time on February 1 that his file-sharing platform was the target of a sophisticated cyber attack.
“Accellion is conducting a full assessment of the ALS data security incident with an industry-leading cybercrime firm,” Accellion spokesman Robert Dougherty said Tuesday. “We will share more information after completing this assessment. For their protection, we do not comment on specific customers. ”
However, the hacker told the newspaper that he directly violated Jones Day’s server and was not associated with the Accellion hack. Bloomberg noted that Jones Day was the second company in two weeks to say it exposed data as part of the attack.
