This page contains detailed information about how to use the python/situational_awareness/host/osx/HijackScanner Empire module. For list of all Empire modules, visit the Empire Module Library.

Module Overview

Name: Dylib Hijack Vulnerability Scanner
Module: python/situational_awareness/host/osx/HijackScanner
Source code: empire/server/modules/python/situational_awareness/host/osx/HijackScanner.yaml
MITRE ATT&CK: T1157
Language: Python
Needs admin: No
OPSEC safe: Yes
Background: No

The HijackScanner module can be used to identify applications vulnerable to dylib hijacking on a target system. This has been modified from the original to remove the dependancy for the macholib library.

This module runs in a foreground and is OPSEC unsafe as it writes on the disk and therefore could be detected by AV/EDR running on the target system.

Note that the HijackScanner module does not need administrative privileges to work properly which means that a normal user can run this module.

LoadedProcesses

Default value: False.
