A group of Russian hackers blamed for the shutdown of a major U.S. fuel pipeline posted a statement online Friday claiming to have stolen confidential information from a Toshiba Corp. group company.
Ransomware group DarkSide declared on the dark web that it had stolen over 740 gigabytes of confidential data from Toshiba Tec Corp.'s base in France.
The company has admitted that a European subsidiary has been the target of a cyberattack, saying it is highly probable that information was leaked.
The data breach is said to include information on products and personnel, with computers believed to be infected with ransomware, a form of malware that encrypts files and makes them inaccessible unless a payment is made.
The U.S. Federal Bureau of Investigation said Monday it had determined that the same group was responsible for the compromise of Colonial Pipeline Co.'s networks, an incident announced by the company last weekend.
Toshiba Tec, a listed subsidiary of Toshiba involved in point of sale systems and other retail solutions, said the impact of the cyberattack was limited to part of Europe and there was no confirmation that customer information had been leaked.
