(This book is the only book so far that analyzes the working mechanism of Linux ELF. This book explains the internal working mechanism of the Linux ELF binary format, the techniques used to detect and analyze UNIX viruses, and the methods for handling binary reinforcement and software tamper-proofing. Patch executable files and process memory, bypass anti-debugging techniques used in malware, perform advanced binary forensic analysis, use C language to design ELF-related tools, and run ptrace on memory.)
