## README

# MimiPenguin 2.0
A tool to dump the login password from the current linux desktop user. Adapted from the idea behind the popular Windows tool mimikatz. This was assigned *CVE-2018-20781* (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-20781). Fun fact it's still not fixed after GNOME Keyring 3.27.2 and still works as of `3.28.0.2-1ubuntu1.18.04.1`.

## Details
Takes advantage of cleartext credentials in memory by dumping the process and extracting lines that have a high probability of containing cleartext passwords. Will attempt to calculate each word's probability by checking hashes in /etc/shadow, hashes in memory, and regex searches. 2.0 introduces a clean C port that aims to increase the speed of execution and portability

## Known Issues
* The 32bit variant of mimipenguin (C build) may fail in a 64bit userspace as it currently does not adequately handle searching a 64bit address space

## Requires
* root permissions

## Supported/Tested Systems
* Kali 4.3.0 (rolling) x64 (gdm3)
* Ubuntu Desktop 12.04 LTS x64 (Gnome Keyring 3.18.3-0ubuntu2)
* Ubuntu Desktop 14.04.1 LTS x64 (Gnome Keyring 3.10.1-1ubuntu4.3, LightDM 1.10.6-0ubuntu1)
* Ubuntu Desktop 16.04 LTS x64 (Gnome Keyring 3.18.3-0ubuntu2)
* Ubuntu Desktop 16.04.4 LTS x64 (Gnome Keyring 3.18.3-0ubuntu2, LightDM 1.18.3-0ubuntu1.1)
* Ubuntu 18
* XUbuntu Desktop 16.04 x64 (Gnome Keyring 3.18.3-0ubuntu2)
* Archlinux x64 Gnome 3 (Gnome Keyring 3.20)
* OpenSUSE Leap 42.2 x64 (Gnome Keyring 3.20)
* VSFTPd 3.0.3-8+b1 (Active FTP client connections)
* Apache2 2.4.25-3 (Active/Old HTTP BASIC AUTH Sessions) [Gcore dependency]
* openssh-server 1:7.3p1-1 (Active SSH connections - sudo usage)

## Building
* To Build the C variant release simply run `make` in the root directory of the project
* To build a debug binary with debug prints run `make debug`
* To build a static linked binaries run `make static`

## Notes
* Password moves in memory - still honing in on 100% effectiveness
* Plan on expanding support and other credential locations
* Working on expanding to non-desktop environments
* Known bug - sometimes gcore hangs the script, this is a problem with gcore
* Open to pull requests and community research
* LDAP research (nscld winbind etc) planned for future

## Development Roadmap
* Implement needles in C port (speed up)
* Add optional arg to target specific users only (speed up)

MimiPenguin is slowly being ported to multiple languages to support all possible post-exploit scenarios. The roadmap below was suggested by KINGSABRI to track the various versions and features. An "X" denotes full support while a "~" denotes a feature with known bugs.

| Feature                                           | .sh | .py |
|---------------------------------------------------|-----|-----|
| GDM password (Kali Desktop, Debian Desktop)       | ~   | X   |
| Gnome Keyring (Ubuntu Desktop, ArchLinux Desktop) | ~   | X   |
| LightDM (Ubuntu Desktop)                          | X   | X   |
| VSFTPd (Active FTP Connections)                   | X   | X   |
| Apache2 (Active HTTP Basic Auth Sessions)         | ~   | ~   |
| OpenSSH (Active SSH Sessions - Sudo Usage)        | ~   | ~   |
