Swift Keylogger: Keylogger for mac written in Swift
Swift Keylogger – macOS Keylogger
It is a simple and easy to use keylogger for macOS. It is not meant to be malicious. There are only a few keyloggers available for Mac and none of them are in Swift.
Another problem is with Apple high-level APIs. I don’t know the reason but Apple suddenly deprecates and removes the documentation of APIs from its website.
So, I don’t want to keep checking about the availability of their APIs and changing my code frequently. That is the reason I went to low-level API which is using HID API.
Most of the keyloggers available only log keystrokes into a file without much information about on which app the keystrokes are generated.
Note: This keylogger doesn’t capture secure input fields like passwords due to EnableSecureEventInput
Usage Swift Keylogger
Clone the repository and open the project in Xcode and build the project and run the executable.
git clone https://github.com/SkrewEverything/Swift-Keylogger.git
To run it in the background
To be able to close the Terminal when Keylogger is running, use this command while running the executable.
$ nohup ./Keylogger &
And you can quit the Terminal.
To quit/stop the Keylogger
To quit the Keylogger, first, find its PID using ps and use kill to stop the keylogger.
$ ps -e | grep “Keylogger”
$ kill -9 pid_of_keylogger_from_above_command
When it’s run, it creates folder Data
Key folder stores all the keystrokes according to the application. App folder stores all the timestamps of applications being active. Devices folder stores the information on the connected keyboards.
By default, it creates a folder where the executable is present. To change the path edit bundlePathURL in Keylogger.swift
All the data is grouped according to day in each folder.
