How to use

There are several features in this plugin:

PDB file generation

The PDB can optionally include symbols for function labels: use Generate .PDB file (with function labels) (or Ctrl+Shift+5).

LIB file generation

• Open target executable in IDA
• Edit -> FakePDB -> Generate .LIB file
• get LIB file from the IDA database directory

IDA database export to .json

• Open target executable in IDA >= 7.0
• Edit -> FakePDB -> Dump info to .json (or Ctrl+Shift+1)
• it will generate filename.json near the .idb file

Binary signature search

• Open target executable in IDA >= 7.0
• Set cursor on start of the target function
• Edit -> FakePDB -> Find signature (or Ctrl+Shift+2)
• signature will be displayed in IDA console

Function names import from .json file

• Open target executable in IDA >= 7.0
• Edit -> FakePDB -> Import offset from .json (or Ctrl+Shift+3)

required file format:

{
   "function_name_1": "0001:123456",
   "function_name_2": "0001:254646",
   "function_name_X": "XXXX:YYYYYY",
   "function_name_Y": "0x0124567AF",
}

where:

• XXXX: number of the PE section
• YYYY: offset from the begining of the section in decimal numbers
• 0x0124567AF: IDA effective address
