Accenture confirmed the invasion of one of its networks and the exfiltration of information by the operators of the LockBit ransomware during a cyber attack in August 2021. The incident was reported in the company’s fourth quarter financial report and annual report for which fiscal year was closed on August 31, 2021.
LockBit operators claimed to have stolen 6TB of data from Accenture’s network and demanded payment of a ransom of $50 million. Although they obtained information from Accenture’s systems and posted it online, the company has not previously disclosed the data breach or sent data breach notification letters to the appropriate authorities. This indicates that the stolen data did not contain any personally identifiable information or protected health information, which would require reporting to regulatory regulators. The company rejected accusations made by LockBit operators that they had also obtained credentials from Accenture customers, which would allow them to attack their networks.
