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, contested that his network was breached. The statement said a file-sharing company she used was recently compromised and had information collected. Jones Day said he is continuing to investigate the breach and will continue to discuss it with affected clients and the relevant authorities.
The post by a person who identified himself as a hacker, known by the name of Clop, includes some individual documents that are easily reviewed by the public, including The Wall Street Journal. One memo is for a judge and is marked as “confidential mediation summary”, the other is a cover letter for “confidential documents”. The Journal could not immediately confirm its authenticity.
The Journal was able to see the existence of many other files – gigantic in size – also allegedly belonging to Jones Day, posted by the hacker on the so-called dark web. Hackers often publish this stolen information after the hacked entity is unable to pay the ransom. The Journal was able to contact the hacker via email on his blog.
