Cyberbrewery Crisis: Asahi’s $335M Hangover from Qilin Ransomware Attack
The Qilin ransomware group has taken credit for a cyberattack on Asahi, Japan’s largest brewing company. After allegedly exfiltrating 27GB of data, Qilin published the breach details online. The attack disrupted operations at six breweries and may cost Asahi up to $335 million. Asahi is investigating while working to resume production.

Hot Take:
Looks like the Qilin ransomware group is trying to make Asahi’s iconic “Super Dry” beer even drier by draining their digital resources dry! Who knew that a cyberattack could make you thirstier for beer? The Qilin gang sure knows how to pour salt in the wound — and by salt, we mean a whopping 27GB of sensitive data. Let’s hope Asahi can bounce back before their brewing operations turn as flat as a day-old pint.
