IDBTOOL
A tool for extracting information from IDA databases.
idbtool
knows how to handle databases from all IDA versions since v2.0, both i64
and idb
files.
You can also use idbtool
to recover information from unclosed databases.
Download
Two versions of this tool exist:
One written in python
One written in C++
Both repositories contain a library which can be used for reading .idb
or .i64
files.
Usage
Usage:
idbtool [options] [database file(s)]
-
-n
or--names
will list all named values in the database. -
-s
or--scripts
will list all scripts stored in the database. -
-u
or--structs
will list all structs stored in the database. -
`--imports` will list all imported symbols from the database
-
-e
or--enums
will list all enums stored in the database. -
-i
or--info
will print some general info about the database. -
-d
or--pagedump
dump btree page tree contents. -
--inc
,--dec
list all records in ascending / descending order. -
-q
or--query
search specific records in the database. -
-m
or--limit
limit the number of results returned by-q
. -
-id0
,-id1
dump only one specific section. -
--i64
,--i32
tell idbtool that the specified file is from a 64 or 32 bit database. -
--recover
group files from an unpacked database.
query
Queries need to be specified last on the commandline.
example:
idbtool [database file(s)] --query "Root Node;V"
Will list the source binary for all the databases specified on the commandline.
A query is a string with the following format:
- [==,<=,>=,<,>] - optional relation, default: ==
- a base node key:
- a DOT followed by the numeric value of the nodeid.
- a HASH followed by the numeric value of the system-nodeid.
- a QUESTION followed by the name of the node. -> a 'N'ame node
- the name of the node. -> the name is resolved, results in a '.'Dot node
- an optional tag ( A for Alt, S for Supval, etc )
- an optional index value
example queries:
Root Node;V
-> prints record containing the source binary name?Root Node
-> prints the Name record pointing to the root>Root Node
-> prints the first 10 records starting with the root node id.<Root Node
-> prints the 10 records startng with the recordsbefore the rootnode..0xff000001;N
-> prints the rootnode name entry.#1;N
-> prints the rootnode name entry.
A full database dump
Several methods exist for printing all records in the database. This may be useful if you want to investigate more of IDA''s internals. But can also be useful in recovering data from corrupted databases.
--inc
,--dec
can be used to enumerate all b-tree nodes in either forward, or backward direction.- add
-v
to get a prettier key/value output
- add
--id0
walks the page tree, instead of the node tree, printing the contents of each page--pagedump
linearly skip through the file, this will also reveal information in deleted pages.
naked files
When IDA or your computer crashed while working on a disassembly, and you did not yet save the database,
you are left with a couple of files with extensions like .id0
, .id1
, .nam
, etc.
These files are the unpacked database, i call them naked
files.
Using the --filetype
and --i64
or --i32
options you can inspect these naked
files individually.
or use the --recover
option to view them as a complete database together.
idbtool
will figure out automatically which files would belong together.
idbtool
can figure out the bitsize of the database from an .id0
file, but not(yet) from the others.
LIBRARY
The file idblib.py
contains a library.
TODO
- add option to list all comments stored in the database
