[Hook Analyser 2.5] Application (and Malware) Analysis tool

Monday, May 13, 2013


Application (and Malware) Analysis tool. Hook Analyser is a hook tool which could be potentially helpful in reversing application and analysing malwares.


Changelog v2.5

This has now five (5) key functionalities:
  1. Spawn and Hook to Application – This feature allows analyst to spawn an application, and hook into it. The module flow is as following -
    1. PE validation (with XOR bruteforce)
    2. Static malware analysis.
    3. Other options (such as pattern search or dump all)
    4. Type of hooking (Automatic, Smart or manual)
    5. Spawn and hook

Currently, there are three types of hooking being supported –
  • Automatic – The tool will parse the application import tables, and based upon that will hook into specified APIs
  • Manual – On this, the tool will ask end-user for each API, if it needs to be hooked.
  • Smart – This is essentially a subset of automatic hooking however, excludes uninteresting APIs.

2. Hook to a specific running process-The option allows analyst to hook to a running (active) process. The program flow is –
  1. List all running process
  2. Identify the running process executable path.
  3. Perform static malware analysis on executable (fetched from process executable path)
  4. Other options (such as pattern search or dump all)
  5. Type of hooking (Automatic, Smart or manual)
  6. Hook to a specific running process
  7. Hook and continue the process

3. Static Malware Analysis – This module is one of the most interesting and useful module of Hook Analyser, which performs scanning on PE or Widows executables to identify potential malware traces. The sub-components have been mentioned below (and this is not the full list) -
  1. PE file validation (with XOR bruteforce)
  2. CRC and timestamps validation
  3. PE properties such as Image Base, Entry point, sections, subsystem
  4. TLS entry detection.
  5. Entry point verification (if falls in suspicious section)
  6. Suspicious entry point detection
  7. Packer detection
  8. Signature trace (extended from malware analyser project), such as Anti VM aware, debug aware, keyboard hook aware etc. This particular function searches for more than 20 unique malware behaviours (using 100’s of signature).
  9. Import intel scanning.
  10. Deep search (module)
    Online search of MD5 (of executable) on Threat Expert.
  11. String dump (ASCII)
  12. Executable file information
  13. Hexdump
  14. PEfile info dumping
  15. …and more.

4. Application crash analysis – This module enables exploit researcher and/or application developer to analyse memory content when an application crashes.This module essentially displays data in different memory register (such as EIP).

5. Exe extractor – This module essentially extracts executables from running process/s, which could then be further analysed using Hook Analyser , Malware Analyser or other solutions. This module is potentially useful for incident responders
