OllyDbg is a 32-bit assembler level analysing debugger for Microsoft Windows. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable. OllyDbg is a shareware, but you can download and use it for free. Special highlights are:
  • Intuitive user interface, no cryptical commands
  • Code analysis - traces registers, recognizes procedures, loops, API calls, switches, tables, constants and strings
  • Directly loads and debugs DLLs
  • Object file scanning - locates routines from object files and libraries
  • Allows for user-defined labels, comments and function descriptions
  • Understands debugging information in Borland format
  • Saves patches between sessions, writes them back to executable file and updates fixups
  • Open architecture - many third-party plugins are available
  • No installation - no trash in registry or system directories
  • Debugs multithread applications
  • Attaches to running programs
  • Configurable disassembler, supports both MASM and IDEAL formats
  • MMX, 3DNow! and SSE data types and instructions, including Athlon extensions
  • Full UNICODE support
  • Dynamically recognizes ASCII and UNICODE strings - also in Delphi format!
  • Recognizes complex code constructs, like call to jump to procedure
  • Decodes calls to more than 1900 standard API and 400 C functions
  • Gives context-sensitive help on API functions from external help file
  • Sets conditional, logging, memory and hardware breakpoints
  • Traces program execution, logs arguments of known functions
  • Shows fixups
  • Dynamically traces stack frames
  • Searches for imprecise commands and masked binary sequences
  • Searches whole allocated memory
  • Finds references to constant or address range
  • Examines and modifies memory, sets breakpoints and pauses program on-the-fly
  • Assembles commands into the shortest binary form
  • Starts from the floppy disk
and much, much more!
