Asahi - Cybersecurity badly
A case example of cybersecurity done poorly.
Wish the article contained more details, so I will have to do some research when I get back to civilization to learn more. Details at bottom of the post are AI generated - saves hours of searching - its also wrong.
This is what Australians call a "cluster fuck"
How hackers forced brewing giant Asahi back to pen and paper
The maker of Japan’s most popular beer, Super Dry, was hit by a major cyber-attack last month.
That's because Asahi, the maker of Japan's best-selling beer, was forced to halt production at most of its 30 factories in the country at the end of last month after being hit by a cyber-attack.
While all of its facilities in Japan - including six breweries - have now partially reopened, its computer systems are still down.

Japan’s favorite beer brand is reeling from a cyberattack that paralyzed its production last week. Its factories have started brewing again, and some truckloads of beer are leaving its warehouses, but the attack has spotlighted the poor cybersecurity readiness among top-tier companies in the world’s fifth-largest economy.

''On Tuesday, Qilin, a ransomware group with a track record of infiltrating organizations around the world, claimed responsibility, saying it had stolen around 27 gigabytes of data."
Exclusive: Qilin ransomware affiliate claims Asahi hack, Aussie data compromised
Australian employee data caught up in what the hacking group calls “a global information leak”, totalling an alleged 27 gigabytes of data.

✅ In summary:
- How: Likely via a compromised endpoint or exposed service.
- Mechanism: Malware (probably ransomware/wiper) that disrupted ERP and production systems, spreading laterally.
- Why it spread: Centralized IT/OT integration, weak segmentation, and the sheer scale of Asahi’s interconnected operations.
Leon, given your background in compliance and technical troubleshooting, this case is a textbook example of why runtime evidence, segmentation, and layered defense are critical. It’s not just about perimeter defense—it’s about containing blast radius once an attacker is inside.
Interesting times. Ill flesh this out later.
