Investing.com-- Japanese beer and beverage giant Asahi Group’s (TYO:2502) shares were set for a steep weekly loss after production at domestic factories was halted indefinitely due to a debilitating cyberattack. Asahi shares fell 0.8% on Friday and were trading down nearly 7% this week. The company halted production at most of its 30 plants in Japan earlier this week, after a cyberattack caused system outages and disrupted even order processing, shipping, and call center operations. Local media reports said Japan could face a beer shortage from an extended production halt at Asahi, which is one of the country’s biggest beverage makers.
