2022-08-12, 15:30–16:30 (US/Pacific), Talks (Virtual)

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


We'll walk through the structures of a PDF, analyzing each part of it, demonstrating how Threat Actors work in the inclusion of malicious components in the structures of the file, in addition to demonstrating the collection of IOC(Indicators of Attack)s and how to build IOA(Indicators of Attack) for analysis by behavior, to anticipate new attacks. Demonstrating structures in the binaries as a PDF(header/ body/cross-reference table/trailer) and performing a comparison of malicious PDFs, 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.
