He is proficient in writing evasive malware and is trained by Renz00h of Sektor7, Rake from GuidedHacking, "0ffset"/Daniel Bunce from Zero2Automated and Cyber-Defense from John Strand.

Chang also won five National Cyber League Seasons, holding five Individual Diamond Player Titles and Five Team Diamond Titles between the Seasons of Fall 2021 to Fall 2023. He currently is coaching his own team for the Spring 2024 Season.

Chang Tan wrote the book "Cyberwarfare for Evasive Cyber Tactics", published by OrangeAVA Education Ltd. and the technical reviewer is Kenneth Underhill, a graduate of Western Governor's University and a Certified Computer Hacking Forensic Investigator.

The book starts off with historical coverage of notable campaigns of cyberwarfare, hacktivism, cybercrime and various notable personalities like the notorious patriot hacker th3j35t3r, by which the basis of the book is built around, also known as "The Jester Dynamic" as covered by the SANS Institute. The reader is then taught the basics of Operational Security and Information Warfare Techniques as well as organizing Clandestine Cell Systems before immediately entering a coverage of obfuscation techniques and writing proof-of-concept evasive malware using multiple code templates from Sektor7, a custom loader, and persisting with a userland rootkit.

There is a huge difference between Evading Defenses and Evading Pursuers. Evading defenses is relatively easy and common knowledge if you look for it. But evading a persistent pursuer is a constant game of cat-and-mouse with severe, permanent, consequences. The former is taught through structured training. The latter is mainly self-taught.
