The Journal reported that it was unable to immediately confirm the authenticity of the documents.
The hacker told the newspaper that he contacted the law firm on February 3 to inform him that his network had been hacked, but had not responded until Tuesday.
Jones Day breach was first reported on the cybersecurity blog DataBreaches.net on February 13th.

The company acknowledged to the Journal that it had exposed data, but attributed it to another cyber attack on the Accellion FTA file transfer platform.
“Jones Day was informed that Accellion’s FTA file transfer platform, which is a platform that Jones Day – like many law firms, companies and organizations – used, was recently compromised and the information was collected,” said the office. advocacy in a statement to the Bloomberg Law.
“Jones Day continues to investigate the breach and has been, and will continue to be, in discussion with affected customers and the appropriate authorities,” said the statement.
The law firm did not immediately return a request for comment from The Hill.
Accellion first released on February 1, that its file-sharing platform was the target of a sophisticated cyber attack.

For your protection, we do not comment on specific customers. “
However, the hacker told the Journal that they breached Jones Day’s server directly and were not associated with the Accellion hack. Bloomberg noted that Jones Day was the second company in two weeks to say it had exposed data as part of the attack.
