This is a keylogger for Linux written in Rust, ported from my original keylogger in C. It works by reading directly from the keyboard device in /dev/input/. The keylogger attempts to detect the keyboard device upon startup, but if one cannot be detected or if multiple are detected, you must specify the path to the device file manually.
Only the US keyboard layout is supported. See input.rs if you are interested in adding mappings for other keyboard layouts.
I am not responsible for how you use this tool.
Clone the repository:
$ git clone git@github.com:gsingh93/keylogger.git
$ cd keylogger
Build the code:
$ cargo build --release
You can run the code with Cargo or directly from the target directory. Note that the keylogger must be run as the root user:
$ sudo cargo run --release -- -h
$ sudo ./target/release/keylogger -h
You can move the keylogger binary wherever you want. For example, you can put it in /usr/local/bin or in any other directory in your path.
$ sudo cargo run -- -h
Usage: target/release/keylogger [options]
Options:
-h --help prints this help message
-v --version prints the version
-d --device DEVICE specify the device file
-f --file FILE specify the file to log to
If the -f flag is not specified, the file keys.log is used.
If you would like to run the keylogger in the background, append an & to the end of the command. If you would like to run the keylogger as a daemon or at startup, use init script/service manager that comes with your distro. An example systemd file is provided.
