The hacking group reportedly posted 29 images to its website that it claims to be internal Asahi Group Holdings documents. However, the authenticity of those files has not yet been confirmed.
Asahi Group Holdings announced a “systems failure” due to a cyberattack on its domestic business last week, affecting order-taking, production and distribution.
On Friday, the company said the breach involved ransomware and could have led to data being stolen.
Just Drinks asked Asahi to confirm Qilin was the group responsible. A spokesperson said: “As the matter is currently under investigation, we would like to refrain from commenting, including on the specific name of group claiming responsibility.”
