A hacker claims to have stolen files from the global law firm Jones Day and posted many of them on the dark web.
Jones Day has many high profile clients, including former President Donald Trump and large corporations.
Jones Day disputed in a statement that his network has been breached. The statement said a file sharing company that used it was recently compromised and information was gathered. Jones Day said it will continue to investigate the breach and engage with affected customers and the relevant authorities.
The publication by a person who identified himself as the hacker, named Clop, contains a few individual documents that can be easily viewed by the public, including The Wall Street Journal. One memo is for a judge and is marked as ‘confidential mediation letter’, another is a cover letter for attached ‘confidential documents’. The Journal could not immediately confirm their authenticity.
The Journal was able to see the existence of many more files – gigantic in size – that also allegedly belonged to Jones Day, posted by the hacker on the so-called dark web. Hackers usually post such stolen information after the hacked entity has not paid a ransom. The Journal was able to contact the hacker via an email on its blog.
