A cohort of Russian-speaking hackers known as Qilin has claimed responsibility for a ransomware attack that hobbled Asahi Group Holdings Ltd’s operations for more than a week.
The group stole roughly 27 gigabytes of data from Japan’s biggest beer brewer including financial documents, contracts, development forecasts and employees’ information, Qilin said on its website. Bloomberg was unable to verify the authenticity of the claims. Asahi is investigating the breach, a spokesperson for the Tokyo-based company said, declining to provide more details.
