Viettel Cyber Security is a Vietnam-based cybersecurity organization and competitive vulnerability research team known for participating in Pwn2Own. Publicly documented activity ties the team to successful exploit demonstrations against consumer and small-business technology products including NAS devices, printers, audio devices, and home automation platforms. Reported demonstrations include exploitation of QNAP, Sonos, Lexmark, and Home Automation Green targets using techniques such as command injection and multi-bug exploit chains. Individuals publicly associated with the team include Dinh Ho Anh Khoa and Phan Vinh Khang. Available information supports characterization as a legitimate security research team focused on vulnerability discovery and exploit development rather than a malicious intrusion set or threat actor conducting real-world campaigns.
