A major Russian telecommunications provider, Rostelecom, said that it is investigating a suspected cyberattack on one of its contractors after hackers claimed to have leaked the company’s data.

Earlier on Tuesday, the hacker group, which calls itself Silent Crow, published a data dump containing thousands of customer emails and phone numbers allegedly stolen from Rostelecom.

“We’re currently reviewing the database to determine which data was compromised and whether it’s related to the company,” Rostelecom said in a comment to state-owned media. “Based on initial findings, it appears that there wasn’t any leak of highly sensitive personal data.”
