Over 46 Japanese Businesses, incl Banks and Government Agencies,Targeted by Cyberattacks

At least 46 Japanese entities, including banks and government agencies, were targeted by cyberattacks utilizing the same malware, causing temporary service suspensions. According to Trend Micro Inc., Japan Airlines Co., NTT Docomo Inc. and major banks were among the victims of distributed denial-of-service, or DDoS, attacks in which networks are overwhelmed by data from multiple sources over a short period, causing temporary service suspensions. The Japan Weather Association said on Thursday it was hit by a cyberattack that rendered its information website inaccessible for over nine hours from around 7 a.m. A similar cyberattack on Sunday that affected both the web and app versions of the weather site took over 7 hours to resolve.

"We can't rule out the possibility that multiple groups conducted attacks at the same time," a Trend Micro official said. The hackers were able to simultaneously control devices including cameras and home appliances connected to the internet to carry out the attacks, the security firm said.
