Global consultancy giant Accenture has confirmed that ransomware operators stole proprietary information from its systems during an attack that hit the company’s systems in August 2021.
The information was revealed in the company’s financial report for the fourth quarter and full fiscal year, which ended on 31 August 2021.
“In the past, we have experienced, and in the future, we may again experience, data security incidents resulting from unauthorized access to our and our service providers’ systems and unauthorized acquisition of our data and our clients’ data including: inadvertent disclosure, misconfiguration of systems, phishing ransomware or malware attacks,” Accenture said.
“During the fourth quarter of fiscal 2021, we identified irregular activity in one of our environments, which included the extraction of proprietary information by a third party, some of which was made available to the public by the third party.
“In addition, our clients have experienced, and may in the future experience, breaches of systems and cloud-based services enabled by or provided by us.”
The LockBit ransomware gang claimed to have stolen six terabytes of data from Accenture’s network and demanded a $50 million ransom.
In September, the company denied claims made by the LockBit gang that they also stole credentials belonging to Accenture customers that would enable them to compromise their networks.
Accenture has stressed that all affected systems were fully restored from backups, with no impact on Accenture’s operations or its clients’ systems.
