Chang Tan

Chang "Slayer-Ranger" Tan is a software-engineer that writes front-end web applications as a primary trade of business with a emphasis of a security-focused software development lifecycle (spiral methodology). He is currently taking the Penetration Testing with Kali Linux course right now. Later he will pursue the CSSLP (Certified Secure Software Lifecycle Professional).

He is a volunteer instructor at DEFCON 27 (2019) at the Red Team Village for Exploit-Development where he and his fellow volunteers and staff members oversaw the validation of approximately more than 90 newly-minted exploit developers over a course of 3-4 days.

He has also, through the negotiation of contracts and non-disclosure agreements (of parties involved and detailed source code), reverse-engineered multiple front-end web applications, primarily by relying on the inference attack on downloadable front-end code in order to infer the functionality and design of the back-end.
