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 Systems


 

  • 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)
  • 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)

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


 

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.
