REvil claims to have stolen data from Sol Oriens

Last week, the REvil ransomware operation listed companies whose data they were auctioning off to the highest bidder.

One of the listed companies is Sol Oriens, where REvil claims to have stolen business data and employees’ data, including salary information and social security numbers.

As proof that they stole data during the attack, REvil published images of a hiring overview document, payroll documents, and a wages report.

As a way to pressure Sol Oriens into paying the threat actor’s extortion demands, the ransomware gang threatened to share “relevant documentation and data to military angencies (sic) of our choise (sic).”

In a statement shared by Javers on Twitter, Sols Oriens confirmed a cyberattack in May 2021 that affected their network.

“The investigation is ongoing, but we recently determined that an unauthorized individual acquired certain documents from our systems.”

“Those documents are currently under review, and we are working with a third-party technological forensic firm to determine the scope of potential data that may have been involved.”

“We have no current indication that this incident involves client classified or critical security-related information. Once the investigation concludes, we are committed to notifying individuals and entities whose information is involved.”

Like many other ransomware operations, REvil is believed to be operating out of Russia or another CIS country.
