Ethereum Node Security Toolkit

Handy toolkit for (security) researchers poking around Ethereum nodes and contracts, now with a slick command-line interface, with auto complete commands and history.

Other functionalities:

• Conversions (toWei, fromWei, keccak, etc)
• Query for balance, code, storage of smart contracts, ecrecover
• etc

This package is extremely beta

Installation

Require Python 3.6.

git clone https://github.com/shayanb/Legions
cd Legions
pip install .

or

pip install legions

	ecrecover	Get address associated with the signature (ecrecover) BUGGY
	storage	Read the storage of a contract (count default = 10)
	command	Manual RPC method with args
investigate		Investigate further in the node (e.g. check if accounts are unlocked, etc)
	accounts	Investigate accounts (e.g. check if accounts are unlocked, etc)
	admin	Investigate accounts (e.g. functionalities under the admin_ namespace)
	sign	Investigate signature functionalities
ens		Do Ethereum Name Service queries (supported on the mainnet only)
	toName	Transform an address to the ENS name
	toAddress	Transform an ENS name to the Ethereum public address
	info	Get details about an ENS name

Acknowledgement

• Interactive shell: python-nubia
• Web3.py

TODO:

• Able to connect to ws / http / https / IPC
• Fix Verbose Status bar (It does not change from OFF)
• Print Accounts in getnodeinfo in a pretty format (One per line)
• A way to reinitiate w3 (web3) by setting it to new host (right now it works for sethost but getnodeinfo still uses the first initiated w3)
• add way more functionalities
• chains.json depending on the execution path might not be found. fix it.
• inline TODOs (tons)
