Counterfeit Chinese USB Drives Compromise Japan's Self-Defense Forces

**Executive Summary:** Counterfeit USB drives distributed during disaster relief operations and used by Japan's Ground Self-Defense Force contained malware linked to known Chinese hacking groups; six of eight tested drives were infected, more than 50 computers (including isolated systems handling sensitive data) were affected, and the malware persisted undetected for nearly a year due to procurement lapses and antivirus not scanning USB devices.
