PE Tree is a Python module for viewing Portable Executable (PE) files in a tree-view using pefile and PyQt5. It can also be used with IDA Pro, Ghidra, Volatility, Rekall and minidump to view and dump in-memory PE files, as well as perform import table reconstruction.

The PE Tree IDAPython plugin finds portable executables in IDA databases.
- IDA Pro 7.0+ with Python 2.7
- IDA Pro 7.4+ with Python 2.7 or 3.5+
- Easy navigation of PE file structures
- Double-click on a memory address in PE Tree to view in IDA-view or hex-view
- Search an IDB for in-memory PE images and;
- Reconstruct imports (IAT + IDT)
- Dump reconstructed PE files
- Automatically comment PE file structures in IDB
- Automatically label IAT offsets in IDB
To install and run as an IDAPython plugin you can either use setuptools or install manually.
-
Download pe_tree and install for the global Python interpreter used by IDA:
$ git clone https://github.com/blackberry/pe_tree.git $ cd pe_tree $ python setup.py develop --ida -
Copy pe_tree_ida.py to your IDA plugins folder
-
Download pe_tree and install requirements for the global Python interpreter used by IDA:
$ git clone https://github.com/blackberry/pe_tree.git $ cd pe_tree $ pip install -r requirements.txt -
Copy pe_tree_ida.py and the contents of
./pe_tree/to your IDA plugins folder
To forgo installing as a plugin, and simply run as a script under IDA, first install the pe_tree package requirements for the global Python installation:
$ pip install -r requirements.txt
Then run pe_tree_ida.py under IDA:
File -> Script file... -> pe_tree_ida.py -> Open
| OS | Plugins folder |
|---|---|
| Windows | %ProgramFiles%\IDA Pro 7.X\plugins |
| Linux | /opt/ida-7.X/plugins |
| Mac | ~/.idapro/plugins |
-
Launch IDA Pro and disassemble a PE file (always select Manual Load and Load Resources for best results!)
-
Load the PE Tree plugin:
Edit -> Plugins -> PE Tree
Below are the basic steps to dump a packed PE file (for example MPRESS or UPX) and reconstruct imports (assuming the image base/entry-point is fairly standard):
-
Launch IDA Pro and disassemble an MPRESS or UPX packed PE file (select Manual Load and Load Resources)
-
Select a debugger (Windows or Bochs) and run until OEP (usually 0x00401000, but not always!)
-
At this point you could take a memory snapshot (saving all segments) and save the IDB for later
-
Ensure IDA has found all code:
Options -> General -> Analysis -> Reanalyze program -
Open the PE Tree IDAPython plugin, right-click in the right-hand pane and select:
Add PE -> Search IDBThis will scan the IDB for MZ/PE headers and display any modules it finds.
-
Right-click on HEADER-0x00400000 (or appropriate module name) and select Dump...
-
Specify the AddressOfEntryPoint (typically 0x1000, but again, not always!)
-
Ensure Rebuild IDT/IAT is selected
-
Dump!
A new executable will be created using the unpacked section data obtained from memory/IDB, whilst a new section named .pe_tree and containing the rebuilt IAT, hint name table and IDT will be appended to the PE file (much like an .idata section).
If the entry-point memory segment has been marked writable during execution (via VirtualProtect for example) then the entry-point section's characteristics will also be marked writable.
Finally, the BASERELOC, BOUND_IMPORT and SECURITY data directories are marked null, and the OPTIONAL_HEADER checksum is recalculated (if specified).
Using the above approach it is possible to dump many in-memory PE files that have either been unpacked, injected, reflectively loaded or hollowed etc.

The following information will be shared with 3rd party web-applications (depending on configuration) under the following conditions:
If the VirusTotal URL is specified in the configuration then metadata such as file hashes, timestamps, etc will be sent to VirusTotal for processing when the user clicks on highlighted links or selects "VirusTotal search" from the right-click context menu.
If the CyberChef URL is present in the configuration then any file data will be base64 encoded and sent to CyberChef for processing when the user selects "CyberChef" from the right-click context menu.
or
Try to upgrade pip to version 20.0+:
$ pip install --upgrade pip
Try uninstalling and reinstalling PyQt5 as follows:
pip uninstall PyQt5
pip uninstall PyQt5-sip
pip install PyQt5 PyQt5-sip
Ensure IDA has found and disassembled all code:
Options -> General -> Analysis -> Reanalyze program
After this is completed try to dump/rebuild imports again.
Please feel free to contribute! Issues and pull requests are most welcome.
