Vietnam’s Top Spot on Apple’s Security Hall of Fame

Apple’s Security Hall of Fame honors individuals and organizations who have identified, reported, and helped resolve critical vulnerabilities within Apple’s ecosystem — from services to iOS/macOS operating systems.

According to Apple’s records, Mr. Nguyễn Văn Hưng – Deputy Director of the Information Security Services Center and head of the Red Team at CMC Telecom – along with his team, has discovered more than 300 vulnerabilities across 13,000 to 15,000 subdomains and products within Apple’s ecosystem since 2021. Notably, CMC Telecom’s Red Team maintained its presence on Apple’s Hall of Fame for 12 consecutive months. These contributions have played an important role in safeguarding billions of Apple users worldwide.

Mr. Nguyen Van Hung Deputy Director of CMC Telecom’s Information Security Services Center, along with his Red Team, has been repeatedly honored in Apple’s Hall of Fame.

“What excites me the most is the passion I get to pursue and knowing that my work is helping protect the global cyberspace,” said Mr. Hưng. “Each bug hunt on platforms like Apple brings invaluable real-world experience, helping me and my team at CMC Telecom become even stronger.”

Red Team – CMC Telecom’s Human-Centered Cybersecurity Strategy

As part of its cybersecurity development strategy, CMC Telecom has prioritized the formation of its Red Team — a dedicated unit that simulates real-world cyberattack scenarios to evaluate clients’ system defenses and incident response capabilities. Led by Mr. Nguyễn Văn Hưng, the Red Team operates under international standards with deep expertise across multiple sectors.

CMC Telecom experts are listed alongside top global professionals on Apple’s Hall of Fame.

The company now boasts nearly 100 certified security experts holding prestigious certifications such as CISA, CISM, CRISC (for risk management and security strategy) and OSCP, OSCE, OSEP, OSCE3 (for offensive security and exploit development), as well as CREST — a globally recognized certification for penetration testing. These experts support clients via the CMC Comprehensive Security Platform (CCSP) and deliver advanced security services such as penetration testing, Red Team simulations, Managed Detection & Response (MDR), vulnerability assessments, and risk governance through services like CMC Managed Security Services and CMC Professional Security Services.

Beyond their international achievements, CMC Telecom’s cybersecurity team has also made a strong impression at domestic tech events. At the Vietnam Security Summit 2025, CMC Telecom’s young Red Team claimed first prize in the CredentialRush challenge at CyberRush, a high-level technical competition for security teams from banks, tech corporations, and major cybersecurity organizations across Vietnam.

From Individual Talent to Organizational Strategy

CMC Telecom’s recurring presence in Apple’s Hall of Fame is the result of a long-term vision focused on strategic investment in talent, global practical experience, and a proactive "Security First" mindset.

CMC Telecom currently provides cybersecurity services to over 3,000 organizations and businesses in Vietnam, particularly in highly security-sensitive sectors such as finance, banking, telecommunications, e-commerce, and logistics.

In an era of increasingly sophisticated cyber threats, lessons learned from global bug hunting campaigns not only strengthen internal capabilities but also offer a practical path for Vietnamese businesses: building battle-tested defenses rather than relying solely on theoretical recommendations.

This achievement once again affirms the global standing of Vietnamese cybersecurity experts — where technical excellence, humility, and forward-thinking defense strategies are key to ensuring a secure and trustworthy digital future.
