Trusted DesignA Chinese-speaking cybercrime group dubbed Gambling Goblin has conducted a sustained campaign against Brazilian organizations since mid-2025, primarily targeting government and educational institutions. The attackers compromise web servers and install malicious Apache modules that silently reverse-proxy visitors to phishing pages while appearing to originate from legitimate domains. These phishing pages impersonate trusted app stores like Google Play and Microsoft Store but actually promote online gambling and sports betting. The operation manipulates search engine rankings by chaining together compromised high-reputation domains, particularly Brazilian government sites. The group deploys an extensive Linux toolkit including custom downloaders, backdoors, credential stealers, and reconnaissance tools, most heavily obfuscated to evade detection. Evidence shows the operation extends beyond Brazil with parallel infrastructure targeting Vietnamese, Spanish, and English-speaking victims.
