Toshiba Tec services customers in the retail distribution, restaurant, logistics and manufacturing industries, and all members of the supply chain, including offices, warehouses, and factories, according to the business unit's website.
The cyberattack comes at an especially sensitive time, considering parent Toshiba's board is under pressure from investors to either improve overall company performance or perhaps sell the overall company.
Toshiba Tech France disclosed the cyberattack in a statement, though the business unit did not mention the dates or specific extent of the attack. Moreover, Toshiba did not mention the specific malware involved -- though the DarkSide ransomware group is believed to be involved, Reuters reports.
The DarkSide ransomware gang was also blamed for the Colonial Pipeline malware attack. The May 2021 pipeline attack squeezed gasoline and jet fuel supplies in certain U.S. regions stretching from Texas to New Jersey. Colonial Pipeline allegedly paid the DarkSide hackers $5 million for decryption keys in a bid to recover from the attack.

How MSSPs Can Mitigate DarkSide Ransomware Threat
MSSPs (managed security services providers) seeking to mitigate potential DarkSide ransomware threats for customers should see this joint CISA-FBI Cybersecurity Advisory about the malware, which surfaced May 11, 2021.
MSSPs working with the U.S. federal government should also read President Biden's executive order on cybersecurity -- which includes specific cyber requirements and deadlines for IT service providers. Biden issued the order on May 12, 2021.
