Following his discovery of the defects, Adobe rolled out a new update for Illustrator.
On its site it said the Common Vulnerabilities and Exposures (CVE) that Khang and cybersecurity software company Trend Micro discovered - CVE-2020-24409, CVE-2020-24410 and CVE-2020-24411 - are mistakes with a high level of priority for fixing.
Dustin Childs, communications manager at Trend Micro, said the vulnerabilities that occurred during Illustrator's PDF file rendering process could be exploited by hackers to gain control of users' computers.
Khang said, "I am proud to have the opportunity to represent Vietnamese malware researchers in contributing to global cybersecurity."
His work has been recognized on numerous occasions in the past by the cybersecurity community.
In the last two years he has detected four CVE flaws in four of the world’s leading cybersecurity companies - Trend Micro (CVE-2019 -14687), McAfee (CVE-2019-3646), Bitdefender (CVE-2019-17100), and ESET (CVE-2020 - 11446).
A number of other Vietnamese cybersecurity experts have also been recognized globally.
In September Le Huu Quang Linh of Vietnam National Cybersecurity Center was honored by Microsoft and ranked 68th in a list of the 100 most valuable security researchers in 2020.
Khang said he plans to focus on security issues in Vietnam since a safe Internet environment would be important for its development.
