Attack method: The attacker initiates an attack by constructing GadgetChain, using RMI/JNDI communication mechanism or third-party libraries (such as CommonsCollections); 3. Utilization conditions: The application receives external input and deserializes, the class path has available classes and no whitelist verification; 4.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
