Installation

This tool will only run on macOS, since the package builders are native to macOS.

2. Launch Operator tool on macOS
3. pip3 install -r requirements
4. python3 iShelly.py

Release Notes

1.1

• Added a temporary patch to fix https://github.com/preludeorg/pneuma/pull/115
• Added support for Pneuma. This means you can use iShelly on the free version of Prelude Operator
• Added support for agent names, which are passed on the command line. This makes it easy to identify agents in Operator that are tied to a specific initial access technique. It also makes it easy for the blue team to hunt for a specific technique: use the cmdline.
