Miuuti Group is a threat actor targeting gambling companies, including both legitimate and illegal operators. Active since at least 2015, it has used multiple zero-day vulnerabilities in communications software and has a complex, fluid membership. Its operations have compromised more than 1,000 gambling companies, exposing gamblers’ identity information, company server credentials, and transfer-platform account credentials. The group exploits Electron-based communications applications to establish initial access. Its techniques include injecting JavaScript through visitor names in customer-service systems and sending specially crafted chat messages. These vulnerabilities allow JavaScript to invoke native functionality and execute commands on recipients’ endpoints. Following compromise, the group conducts lateral movement, captures screenshots, and exfiltrates documents and credentials using command-line utilities and cloud storage. Miuuti Group establishes persistence by modifying an application's ASAR archive to execute remotely retrieved JavaScript whenever the application starts. It conceals this activity by launching an unmodified, newer version of the same application nested within the compromised installation. Subsequent payloads have included Cobalt Strike and WorkWin, a commercial remote-control product with signed components and driver-based protection that complicates removal. One delivery chain downloaded an older Chrome version, disabled its sandbox, and exploited CVE-2021-21220 to execute Cobalt Strike shellcode. The layered progression from communications-software exploitation through application modification to a known browser vulnerability helps obscure the initial compromise and evade detection.

一个针对博彩行业的攻击组，人员构成复杂、流动性强，可能与其他已知组织存在重叠，并长期利用多个通讯软件0day漏洞。
Targets gambling companies using communication-software zero-days, remote-access tools, data theft, and persistent modification of Electron applications. Analysis of 300 GB of attacker-held data identified more than 1,000 compromised legal and illegal gambling companies. Stolen information included gamblers’ identities, gambling-company server credentials, and payment-platform credentials. The researchers suggest possible overlap with known groups but do not establish a definitive organizational identity.
