# OS X Auditor



![Maintenance](https://img.shields.io/badge/Maintained%3F-no-red.svg)

![No Maintenance Intended](http://unmaintained.tech/badge.svg)



OS X Auditor is a free Mac OS X computer forensics tool.



OS X Auditor parses and hashes the following artifacts on the running system or a copy of a system you want to analyze:

 * the kernel extensions

 * the system agents and daemons

 * the third party's agents and daemons

 * the old and deprecated system and third party's startup items

 * the users' agents

 * the users' downloaded files

 * the installed applications



It extracts:

 * the users' quarantined files

 * the users' Safari history, downloads, topsites, LastSession, HTML5 databases and localstore

 * the users' Firefox cookies, downloads, formhistory, permissions, places and signons

 * the users' Chrome history and archives history, cookies, login data, top sites, web data, HTML5 databases and local storage

 * the users' social and email accounts

 * the WiFi access points the audited system has been connected to (and tries to geolocate them)



It also looks for suspicious keywords in the .plist themselves.



It can verify the reputation of each file on:

 * Team Cymru's MHR

 * VirusTotal

 * your own local database



It can aggregate all logs from the following directories into a zipball:

 * /var/log (-> /private/var/log)

 * /Library/logs

 * the user's ~/Library/logs



Finally, the results can be:

 * rendered as a simple txt log file (so you can cat-pipe-grep in them… or just grep)

 * rendered as a HTML log file

 * sent to a Syslog server



## Author



Jean-Philippe Teissier - @Jipe_ & al.



## Development status



**OS X Auditor IS NO LONGER MAINTAINED - YOU SHOULD NOT USE IT** 



## Support



OS X Auditor started as a week-end project and is no longer maintained. It has been forked by the great guys @ Yelp who created osxcollector.



I do recommend you to use to osxcollector (https://github.com/Yelp/osxcollector)



## How to install



Just copy all files from GitHub.



## Dependencies



If you plan to run OS X Auditor on a Mac, you will get a full plist parsing support with the OS X Foundation through pyobjc:

 * `pip install pyobjc`



If you can't install pyobjc or if you plan to run OS X Auditor on another OS than Mac OS X, you may experience some troubles with the plist parsing:

 * `pip install biplist`

 * `pip install plist`



These dependencies will be removed when a working native plist module will be available in python



## How to run



 * OS X Auditor runs well with python >= 2.7.2 (2.7.9 is OK). It does not run with a different version of python yet (due to the plist nightmare)

 * OS X Auditor is maintained to work on the lastest OS X version. It will do its best on older OS X versions.

 * You must run it as root (or via sudo) if you want to use is on a running system, otherwise it won't be able to access some system and other users' files

 * If you're using API keys from environment variables (see below), you need to use the ```sudo -E``` to use the users environment variables



Type `osxauditor.py -h` to get all the available options, then run it with the selected options



eg. `[sudo -E] python osxauditor.py -a -m -l localhashes.db -H log.html`

### 0.4.2

 * CHANGE: Moved API keys from in the code to environment variables



### 0.4.1

 * CHANGE: Search for generic backdoors in LaunchAgentPlist



### 0.4

 * NEW: extracts events (boot/shutdown, hibernation in/out, sudo commands, usb devices, ttys opened/closed, from the system logs and create a (not readable yet) timeline (-e/eventlogs)

 * NEW: extracts users' LoginItems

 * NEW: extracts users' RecentItems

 * NEW: extracts the LastSession from Safari artifacts

 * NEW: extract system groups and users details

 * FIX: wrong os.path.join() calls

 * FIX: bug in the recursive ParsePackagesDir()

 * NEW: provides with the system name, version and build of the audited system

 * NEW: ability to analyze installed Applications (-i/--installedapps)

 * NEW: extracts the Archived History from Google Chrome artifacts

 * NEW: a human readable HTML log report :)

 * FIX: HTMLLog() and SYSLOGLog() now handle exceptions

 * FIX: ParsePackagesDir() is now recursive and only tries to parse apps or kernel extensions. Some DEBUG output added as well

 * FIX: HUGE UTF-8/UNICODE improvement

 * FIX: .DS_Store and .localized files are ignored in ParsePackagesDir()



### 0.3

 * NEW: ability to extract the Wi-Fi APs the audited system has been connected to from the Airport Preferences and tries to geolocate them using Geomena (-A/--airportprefs). You must use -g/--wifiapgeolocate to enable the geolocation (or set GEOLOCATE_WIFI_AP to True in the code).

 * NEW: ability to extract users' social and email accounts (-U/--usersaccounts)

 * FIX: ability to handle the locked sqlite databases especially while auditing a live system

 * FIX: hashes duplicates removed

 * FIX: better identify md5 in the HTML output

 * CHANGE: indicates if a section (Startup items, Packages directory, Db tables, etc…) is empty to clarify the output

 * CHANGE: the downloads artifacts (-d/--downloads) include the old and new Mail.app default download directories



### 0.2.1

 * CHANGE/FIX: implement a BigFileMd5() function to hash very big files, avoid MemoryError execptions and reduce the memory footprint

### 0.2

 * NEW: ability to send the results to a remote syslogd server (-S)

 * NEW: ability to create a zipball of all the log files found on the audited system (-z)

 * CHANGE: the analysis of startup artifacts includes the old and deprecated StartupItems

 * CHANGE: the analysis of startup artifacts includes the ScriptingAdditions

 * CHANGE: the analysis of quarantined artifact includes the old QuarantineEvents for Mac OS X systems <= 10.6

 * CHANGE: great improvement of plist hangling using the Python ⟷ Objective-C bridge (PyObjC) and OS X Foundation

 * CHANGE: some changes in the options parameters (-t, -l)

 * CHANGE: license changed from CC to GPL

 * CHANGE: debug levels are now more consitent in the output logs

 * CHANGE: a small change with the Bootstrap CSS

 * CHANGE: the VirusTotal lookup is now done in a bulk mode

 * FIX: a bug in ParseLaunchAgents() on plist files containing both Program and ProgramArguments keys

### Disk Arbitrator



Disk Arbitrator is Mac OS X forensic utility designed to help the user ensure correct forensic procedures are followed during imaging of a disk device. Disk Arbitrator is essentially a user interface to the Disk Arbitration framework, which enables a program to participate in the management of block storage devices, including the automatic mounting of file systems. When enabled, Disk Arbitrator will block the mounting of file systems to avoid mounting as read-write and violating the integrity of the evidence.
