Japanese Firms Suffer Long Tail of Ransomware Damage

Japanese companies have experienced a wave of ransomware and related cyber incidents that continue to cause long recovery tails and operational disruption—examples include Asahi Holdings (ransomware with a possible 1.9M-person data breach) and Askul (extended outages affecting customers such as Muji). The report also notes exploitation of unpatched Ivanti Connect Secure VPN vulnerabilities, highlights the opportunistic nature of ransomware groups targeting supply-chain-critical industries in Japan, and stresses the importance of preparedness, backups, and recovery exercises to reduce the likelihood of paying ransoms.
