- New: Hooking and logging of various private Internet Explorer functions.
- New: Custom methods for retrieving addresses of private functions.
- Tweak: Allow functions in different modules with the same name to be hooked.
- Tweak: Use LdrLoadDll instead of LoadLibraryW for injection so processes
without kernel32 loaded can be injected as well (thanks Accuvant).
- Tweak: Log module+offset in the stacktrace.
- Tweak: More SetErrorMode flags so not to show an error box under Windows 7
(thanks Accuvant).
- Tweak: Reuse pipe handle for multiple commands.
- New: Use custom slab allocator for allocating hooking function stubs.
- Tweak: Allow analysis of DllMain functionality of loaded DLLs.
- New: Various signatures to improve analysis results on Internet Explorer 6,
Internet Explorer 8, and Firefox 3.6.
- Tweak: Use our own sprintf implementation everywhere (except for capstone).
- Tweak: Get rid of all ws2_32 imports.
- Remove: Get rid of superfluous dropped file tracking.
- New: Pipe-based logging which is more stable than Windows sockets.
- Tweak: Make inject.exe and is32bit.exe unicode compatible.
- New: Log the last error and the nt status for failed api calls.
- Remove: ExitThread and ExitProcess signatures (thanks Accuvant).
- Tweak: Improve compilation so that helper code does not depend on
automatically generated code, therefore improving compilation time when
working on signatures.
- Remove: Removed minimum OS logic - just hook everything that can be hooked.
- New: Various function signatures that eliminate unnecessary log entries.
- Tweak: Change from iterating through unicode buffers to basic memory
management where each allocated buffer has to be freed.
- New: Start on unittests of monitor functionality.
- Tweak: Provide our own implementation of more general purpose functionality.
- Feature: Allow the current working directory to be set when creating a new
process.
- New: Introduce is32bit.exe to inject the 32-bit or 64-bit monitor based on
the original executable of the process to be injected.
- Feature: Fixup compiler warnings, introduce stacktrace() in 64-bit mode, and
fixup 64-bit calling convention in order to allow 64-bit analysis.
- Feature: Create process from another injected process - select by process
name.
- Rewrite: Completely rewritten inject.c (was dllinject.c) to be used for
injection by Cuckoo. Supports process creation from within another process
and various other nifty tricks.
- New: Logic for ignoring function calls referencing ignored object handles.
- Tweak: Place hook after the "mov eax, imm32" instruction for hooked system
call wrappers (i.e., functions starting with Nt).
- Tweak: Move prelog support logic from TLS entries to the relevant functions.
- Tweak: Add verbose error reporting where useful to possibly avoid bricking
the monitor in the near future.
- Tweak: Modify almost all native API usage to go through our custom system
call wrappers and memory allocator.
- New: Introduce various native system call wrappers for directly executing
system calls. Implement basic memory allocator based on it.
- Tweak: Properly fetch and restore last error codes by directly modifying
the TEB.
- Huge tweak: Completely get rid of the TLS-based hook information state. The
relevant hook information (i.e., are we inside a hook?) is now obtained
through stacktraces.
- Tweak: A couple more ignored special filepaths.
- Tweak: Properly normalize registry keys.
- Tweak: Move actual exception logging outside of the exception handler.

processes (thanks Accuvant).

- Bugfix: APC Injection requires the thread identifier (thanks Accuvant).

- Add: A few Crypto and OLE signatures.
- Tweak: Remove dead unhook detection regions when unloading a DLL.

- Feature: Added Replace section for signatures.
- Tweak: Resolve monitors' symbols while destroying its PE header.
- Bugfix: Announce new threads to Cuckoo.

Accuvant).
- Bugfix: Improved various native registry hooks, un-crashing calc.exe (thanks
Thorsten Sick).
- Bugfix: limit to a maximum of 1024 exceptions avoiding huge logs. Logs this
behavior (excessive exception count) as anomaly.

dozens or even hundreds of kilobytes on the stack.
- Bugfix: long file path resolving (after many attempts).
- Bugfix: registry key path resolving (after many attempts).
- Bugfix: execution never finishing due to unhook detection threads.
- Dump instruction at exception address in debug mode.
