A hacker claims to have stolen files belonging to the global law firm Jones Day and posted many of them on the dark web.
Jones Day has many prominent clients, including former President Donald Trump and large corporations.
Jones Day, in a statement, argued that his network has been breached. The statement said a company that shared files it has used has recently been compromised and information has been taken from it. Jones Day said he continues to investigate the breach and will continue to hold talks with affected customers and competent authorities.
The publication of a person who identified himself as a hacker, named Clop, includes some individual documents that are easily reviewed by the public, including the Wall Street Journal. One note is for a judge and is marked as a “confidential mediation brief,” another is a cover letter of “confidential documents” attached. The Journal could not immediately confirm its authenticity.
The newspaper was able to see the existence of many more files, of enormous size, which also claimed to belong to Jones Day, published by the hacker on the so-called dark web. Hackers usually post this stolen information after the hacked entity does not pay a ransom. The Journal was able to contact the hacker via email on his blog.
