Pivotr - a remote command execution and pivoting framework

Pivotr - A remote command execution framework

The aim of pivotr initially is to simplify the task of maintaining ssh connections throughout a network environment. These connections, which we refer to as 'nodes', are stored in an encrypted file as a list of objects. Each object currently only contains very basic data regarding each node, including a basic node ID (and consequently, the id of the node in the list), the node's IP address, and the option to append a username and password to the node if SSH credentials are known.

Stage 1 - Nodes:

• Implement basic node manipulation, including the ability to add, delete, modify, view nodes
• Implement basic node data persistance (in this case, pickling)
• Successfully send single SSH commands or make SSH connections to nodes with credentials
• Implement pivot functionality to where connections that require jumps between nodes are seamless
• Encrypt all stored data given the need for stored credentials to nodes
• Add 'mapping' functionality to display a basic map of connected nodes via CLI (aesthetically differentiates between nodes with credentials and nodes without)
• Add uploading/downloading to/from nodes via SCP
• Implement a 'snapshot' feature to allow us to save encrypted node data to be utilized later if necessary
• Introduce ping-sweep feature that scans for hosts on a node's subnet and adds all new discoveries as nodes without credentials
• Work on input validation and clean up code

Stage 2 - Agents:

• Implement a master server process to listen for incoming 'reverse' connections
• Add to node object variables in order to account for much larger data sets provided by agents (see next bullet point)
• Design 'agent' executables that, when run, connect back to our pivotr server. These agents will be the hallmark of any non-ssh functionality and will include features such as:
  • The ability to harvest data from their respective hosts and transmit the data back to our pivotr server for safekeeping
  • Remain persistent and callback to the pivotr server after a connection is lost
  • Utilize IDS/IPS avoidance and obfuscation to maintain persistence
  • Transmit data via encrypted channels
  • Cross-platform, non-OS-specific implementation
  • Integration into current node object schema and mapping functionality

Stage 3 - Profit

Setup

Pivotr has recently been ported to PyPI as a pipx download. Downloading pipx:

# Via Debian-based distros (Debian, Ubuntu etc.) using apt
sudo apt update
sudo apt install pipx

# Via RHEL-based distros (Redhat, Fedora, etc.) using dnf
sudo dnf install pipx

# Via Arch-based distros (Arch, Mangaro, etc.) using pacman
sudo pacman -Sy python-pipx

# Via MacOS using homebrew
brew install pipx

Download pivotr via pipx (which both isolates our python environment and also adds a symlink to our executable in the user's path):

pipx ensurepath
pipx install pivotr

Help:n

pivotr -h

Show map of all nodes we currently know about (hard lines are credentialed hosts, dotted lines have no credentials):

pivotr -m

Since our host is node 0 (n0) by default, run a ping sweep from n0 to map our subnet (check to see if ping sweep was successfully by running pivotr -m afterward):

pivotr -n0 -S

Add known SSH credentials to node 10:

pivotr -n10 -e

Current node values:
    1) IP addr:   172.6.12.15
    2) UN:        jsmith
    3) PW:        
    4) Exit:

Select property to edit: 3

New password: ************

Node 10 successfully modified.

Send command uname -a to node 10 via SSH:

pivotr -n10 -c "uname -a"

Make SSH connection to node 10:

pivotr -n10 -i

jsmith@172.6.12.15$

Save our current node data set for later use in ./snapshots directory:

pivotr -s

Use a data set from ./snapshots (which replaces current data set at /tmp/nodes.data):

./pivotr -f ./snapshots/2024-01-15_114534-nodes.data
