BSides Vancouver 2021 Demonstrate different kind of structures in the binaries as a PDF(header/ body/cross-reference table/trailer), explaining how each session works within a binary, what are the techniques used such as packers, obfuscation with JavaScript (PDF) and more, explaining too about some anti-disassembly techniques, demonstrating as a is the action of these malware’s and where it would be possible to “include” a malicious code. By the end of this “talk” it will be clear to everyone, differences in binaries structures, how can the researcher should conduct each of these kind of analyzes, besides of course, it should seek more basic knowledge, with file structures, software architecture and programming language.
