How hackers forced brewing giant Asahi back to pen and paper

Its owner, Sakaolath Sugizaki, expects to get a few more soon, but she says her supplier is keeping the bulk of its stock for bigger customers.

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.

That means it has to process orders and shipments manually - using pen, paper and fax machines - resulting in much fewer shipments than before the attack.
