mimipenguin

A tool to dump the login password from the current linux desktop user. Adapted from the idea behind the popular Windows tool mimikatz.

• Special thanks to pugilist for cleaning up PID extraction and testing.

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.

Requires

• root permissions

Supported/Tested

• Kali 4.3.0 (rolling) x64 (gdm3)
• Ubuntu Desktop 12.04 LTS x64 (Gnome Keyring 3.18.3-0ubuntu2)
• Ubuntu Desktop 16.04 LTS x64 (Gnome Keyring 3.18.3-0ubuntu2)
• XUbuntu Desktop 16.04 x64 (Gnome Keyring 3.18.3-0ubuntu2)
• VSFTPd 3.0.3-8+b1 (Active FTP client connections)
• Apache2 2.4.25-3 (Active/Old HTTP BASIC AUTH Sessions)
• openssh-server 1:7.3p1-1 (Active SSH connections - sudo usage)

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
