Attractive toolkit for the analysis of ELF object files
The ELF shell 0.5 takes advantage of a hash based, lazy typed object oriented architecture, a readline based interactive mode (35+ builtin commands, with history, completion, regular expression powered), a scripting mode (sample scripts and session logs available on this page) and brings more modification API (relocation tables, .interp, .dynamic, .dynsym, PAX bits, and +), atomic operations with get/set and add/sub/mul/div/mod commands, section injection by top (insert unlimited amount of data in the executable PT_LOAD, even in non-executable environments), a quiet output for tiny screens, ELFsh modules support, sophisticated write/printf primitives, SPARC PLT infection, experimental ET_EXEC relocation and remapping features, ET_REL injection into ET_EXEC (with bss and symtab merging support), disassembly (with good resolving) on i386 binaries with libasm, and much more.
