Finally, with IDA v7.2 we introduce a new (experimental) Lumina server. Think of it as about a public storage of popular function patterns. The lumina server holds metadata about functions (like names, comments, prototypes, operand representation, etc). IDA can ask Lumina to recognize functions in the current database and apply the corresponding metadata. It is like FLIRT but it is dynamic, stores more information, and can recognize functions that FLIRT cannot.

кто пробовал Lumina?

Из прикольных вещей: можно юзать хидеры и либы от ванильного питона, и это даже работает.

 

Правда, часть того что инлайнится обычно в malloc() или free() тут вынесена отдельные функции с префиксом BW

 

6 (0x0006),  (0x), BW_Py_arena_free, 0x00103420, None
7 (0x0007),  (0x), BW_Py_arena_malloc, 0x00103440, None
8 (0x0008),  (0x), BW_Py_arena_realloc, 0x00103470, None
3 (0x0003),  (0x), BW_Py_arenaAllocAnnotate, 0x001033f0, None
4 (0x0004),  (0x), BW_Py_arenaFreeAnnotate, 0x00103400, None
5 (0x0005),  (0x), BW_Py_arenaReallocAnnotate, 0x00103410, None
1 (0x0001),  (0x), BW_Py_DEC_REF, 0x001033d0, None
9 (0x0009),  (0x), BW_Py_free, 0x001034a0, None
10 (0x000a),  (0x), BW_Py_getHooks, 0x001034c0, None
2 (0x0002),  (0x), BW_Py_INC_REF, 0x001033e0, None
11 (0x000b),  (0x), BW_Py_malloc, 0x00103520, None
12 (0x000c),  (0x), BW_Py_memoryAnnotateBegin, 0x00103550, None
13 (0x000d),  (0x), BW_Py_memoryAnnotateEnd, 0x00103560, None
14 (0x000e),  (0x), BW_Py_realloc, 0x00103590, None
15 (0x000f),  (0x), BW_Py_setHooks, 0x001035c0, None
1082 (0x043a),  (0x), init_elementtree, 0x001a48b0, None

Предположительно связано с тем, что в WoT используется кастомный аллокатор, вроде бы jemalloc. Обманул, стандартный MSVC'шный, но есть возможность хукаться и профилировать выделение памяти в питоне и других подсистемах.
