Explore a 45-minute conference talk from Ekoparty 2022 that delves into ELF binary construction and the innovative use of ELF sections for payload hosting, retrieval, and loading. Learn about the concept of ELF section docking, which allows for independent attachment of payload-containing sections to loaders. Discover techniques for in-field re-attachment of sections without compilers, useful for long-term offensive operations. Examine how ELF docking serves as an alternative to packing for complex payloads, offering flexibility in various delivery scenarios. Gain insights into detection evasion features implemented in open-source proof-of-concept tools. Presented by Dimitry Snezhkov, a former red team operator now focused on security research and tool development.
