A simple program written in go that checks if users on your linux server have simple passwords.

In order to run the checks, the program uses 'expect' (more precisely, Google's 'goexpect' implementation available at https://github.com/google/goexpect). The "su" command is used in order to attempt to login.

At the moment of writing this, the only passwords that are checked are the following ones:

• password = username
• password = username + 1 digit
• password = username + 2 digits

• Go to https://github.com/Cristi075/lockpicker/releases
• Download the appropriate binary for your target system (x64 or x86)
• Run the binary

Prerequisites: you must have go 1.20 installed on your system

• Clone this repository
• Run "go build"

You can also build both the x86 and x64 versions by running:

GOARCH=amd64 go build -o lockpicker_x64
GOARCH=386 go build -o lockpicker_x86

This is still a work in progress for me.
Here is a list of things that I plan to (eventually) add to this script:

• Improve concurrency. Right now, this is a version that just worked for PoC purposes
• Add flags to allow the user to change the program's behaviour
• Allow the user to select a custom password list
• Allow the user to change how many requests are executed in parallel
• Add more options for generating simple passwords (uppercase/lowercase mutations, more digits, common words, etc)
• ???
