Accenture today declined to comment on reports that it had suffered a ransomware and extortion attack, but it did confirm it had experienced a security incident.

"Through our security controls and protocols, we identified irregular activity in one of our environments. We immediately contained the matter and isolated the affected servers. We fully restored our affected systems from back up. There was no impact on Accenture's operations, or on our clients' systems," an Accenture spokesperson told Dark Reading.

CNN today reported that Accenture had been hit by ransomware and that the LockBit cybercrime group was threatening to post the stolen and encrypted files on its website if the company did not pay the ransom demands.
