US Disrupts China-Linked Integrity Tech ‘s Cyber Espionage Tools

**Executive summary:** U.S. authorities (DOJ and FBI) seized two China-linked hacking tools, Microscan and FishHub, operated by Integrity Technology Group and used since at least 2017 to scan, exploit, and in some cases intrude into critical infrastructure worldwide; Microscan leveraged a Mirai-based IoT botnet and automated vulnerability scanning while FishHub used spear-phishing to deliver malware and exfiltrate data, prompting a multi-country advisory naming Integrity Tech as a for-profit enabler of state-linked malicious cyber activity.
