Ransomware group Clop released confidential data of Jones Day customers to the dark web

Clop ransomware, the threat actor claiming responsibility for the alleged third party data breach Jones Day has released the law firm’s data to the dark web as evidence.

Although the law firm was associated with Donald Trump, experts believe the ransomware attack was unrelated to politics. Ransomware operators also told databreaches.net that they did not encrypt Jones Day files in the process.

The threatening actor has published several archives containing gigabytes of customer data. The first version contains emails, while the second archive contains confidential files allegedly stolen from company servers. According to the WSJ, ransomware operators claim to have over 100 gigabytes of Jones Day data.

Clop ransomware denies exposure to Jones Day due to third-party data breach

An alleged actor in the Clop ransomware threat told the Wall Street Journal that Jones Day was made aware of the data breach on February 3, but did not respond to ransom demands.

Clop also claimed to have stolen the data directly from Jones Day’s servers, but the law firm insisted the data leak was from a third-party data breach.

The Wall Street Journal reported that the leaked Jones Day data contained “Accellion configuration files and logs with references to Jones Day email and web addresses.”

“Like the Solarwinds supply chain attack, cybercriminals are focusing their attacks on third parties and service providers who support many customers,” says James McQuiggan, advocate for advocacy. security at KnowBe4. “These organizations will want to review and elevate their security programs to ensure that they don’t experience any loopholes, which would result in a similar compromise. These attacks harm the organization’s customers and customers, and harm that organization’s reputation and possible outcomes. “

McQuiggan added that third-party vendors should encrypt files before transferring them to protect their customers.

“It is highly likely that a third party or vendor is behind the alleged data breach,” says Ilia Koloshenko, CEO of ImmuniWeb. “Cybercriminals typically start their ‘purchases’ by probing unprotected third parties who have access to the victim’s valuable data. The currently leaked details of the stolen data indicate that the incident has limited impact and that only a limited number of customers and cases are affected. In addition, even if some documents are marked as confidential or privileged, it does not necessarily mean that they always have or have had this protectable status.

In response to the alleged third-party data breach blamed on the Accellion hack, Tim Mackey, Senior Security Consultant, Synopsys Software Integrity Group, said:

“Modern businesses rely on an ecosystem of technology providers that form a digital supply chain. Compromising a business then comes down to identifying the weakest link and accessing the data it has on the business and its customers. While it is traumatic for any business leader to find themselves in the press for a data breach, the incident represents an opportunity. “

The cybercriminal gang could lie to avoid exposing their data source, while the law firm also tries to blame it to save face over such an embarrassing exposure. However, Jones Day’s claims appear credible given the presence of Accellion’s journals in the data exposed.
