A coordinated disruption targeted Chinese-speaking cybercriminals operating three major phishing kits—CoGUI, CoAceV, and CoFish_Ws—that distributed hundreds of millions of credential phishing messages primarily against Japanese organizations. These phishing campaigns impersonated 66 well-known consumer and finance brands to steal usernames, passwords, and payment data. The threat actors used sophisticated evasion techniques, including approximately 17,000 unique rotating domains. The disruption involved civil lawsuits and domain seizures against ecosystem enablers YAM Store and Iron Man, conducted collaboratively by Microsoft, Health-ISAC, and security partners. This action is expected to significantly disrupt multiple threat groups involved in financial fraud within the Chinese phishing ecosystem.
