. Researchers conducting computer virus research at the Royal Air Force's computer security department have come up with the idea of hiding malicious code data in a single-or multi-layer encapsulation to avoid anti-virus systems. That is to say, this is the APT of the 1990s S. Nowadays, many cybersecurity communities tend to tag every security problem that they encounter, and then give them some technical protection summary, this overview will provide
