Contains Stap, python-script and whitelist.txt
Does not fully work. Requires return-value in start_stap function. If that works, it works fully. Then begin with tidy up work.

-# KLDetect
-KLDetect is a keylogger detector for the Linux Desktop.
-It can detect processes reading from ```/dev/input/event*``` devices and kernel modules registered to listen to keyboard events.
-
-# Dependencies
-* [Python](https://www.python.org/downloads/)
-* [SystemTap](https://sourceware.org/systemtap/wiki)
-* [```fuser```](https://www.man7.org/linux/man-pages/man1/fuser.1.html)
-* Utilities that come with [Fedora](https://fedoraproject.org/) like ```which```.
-
-# Setup
-Download or clone this repository:
-```
-git clone https://github.com/sebaschi/keylogger-detector.git
-```
-Navigate into the src directory:
-```
-cd keylogger-detector/src
-```
-Run a keylogger. KLDetect has been tested and shown to work on the following keylogger.
-
-User progams:
-* [simple-key-logger](https://github.com/gsingh93/simple-key-logger/tree/master)
-* [logkeys](https://github.com/kernc/logkeys)
-* [keylog](https://github.com/SCOTPAUL/keylog)
-
-
-Kernel Module:
-* [spy](https://github.com/jarun/spy)
-
-# Usage 
-KLDetect **must** be run as root (sudo). 
-If KLDetect is not run as root the user is reminded to try again with root permissions.
-
-Running without options just runs userspace detection:
-```
-./kldetect.py
-```
-To get a list of command line options:
-```
-./kldetect.py -h
-```
-To run with kernel module detection:
-```
-./kldetect.py -k
-```
-To run just kernel module detection
-```
-./kernel_detector.py
-```
-
-# Warning
-Running any part if this program in a lightheaded manner may break your system.
-Killing processes and unloading modules should be done with caution. We suggest testing it an a VM.
-If one runs the KLDetect with the kernel module keylogger detection option set, make sure to update the [whitelist.txt](https://github.com/sebaschi/keylogger-detector/blob/main/src/whitelist.txt) with the safe kernel modules that you know you have on your system. In particular we highly suggest running ```lsmod > <path-to-kldetect>/whitelist.txt```, before inserting a kernel keylogger. This writes the modules currently inserted in the kernel to the whitelist. This way 'normal' modules that you already have installed on the 'clean' kernel will not accidentally be unloaded. Altough KLDetect should not unload any kernel modules currently used, better safe than sorry.

 ### Sebastian
 VirtualBox stopped working so after much pain I decided to switch to Boxes. There the install of Fedora 37 went smoothly.
-Then Started testing the userland detector on [simple-key-logger](https://github.com/gsingh93/simple-key-logger/tree/master), [logkeys](https://github.com/kernc/logkeys).
+Then Started testing the userland detector on [simple-key-logger](https://github.com/gsingh93/simple-key-logger/tree/maste), [logkeys](https://github.com/kernc/logkeys).
 [pykeylogger](https://github.com/amoffat/pykeylogger) produced a segmentation fault, after I finaly got it to run. Trying to run [py-keylogger](https://github.com/hiamandeep/py-keylogger), turns out it only runs on X11 it seem (so we'd not catch it anyway).
 [keylog](https://github.com/SCOTPAUL/keylog) was succesfully detected and removed.
 All in all, the main functionality works as intended. Basically now would be the refinement phase to add more options or to have a way to configure the config.json file more easily.

These keystrokes can either be stored on a physical hard disk or transmitted via a network connection to a remote location. Because of their functions, keyloggers have a potential of being used for malicious purposes. In order to protect privacy, it is important to realize the threat that a keylogger application might pose and identify appropriate methods for detecting it. The method presented in this research provides a standardized approach to detect unknown keylogging software from a computer. We also conducted experiments on a variety of keyloggers to verify the effectiveness of the proposed approach.},

Victims abused by this targeting malware countered 3,800,000, which is 18.6\% greater than previous year.• Finance-committed malware, associated with Bitcoin has demonstrated the most dynamic development.

Over the course of March, 2016--March, 2017, we identify 788,000 potential victims of off-the-shelf keyloggers; 12.4 million potential victims of phishing kits; and 1.9 billion usernames and passwords exposed via data breaches and traded on blackmarket forums. Using this dataset, we explore to what degree the stolen passwords---which originate from thousands of online services---enable an attacker to obtain a victim's valid email credentials---and thus complete control of their online identity due to transitive trust. Drawing upon Google as a case study, we find 7--25\% of exposed passwords match a victim's Google account. For these accounts, we show how hardening authentication mechanisms to include additional risk signals such as a user's historical geolocations and device profiles helps to mitigate the risk of hijacking. Beyond these risk metrics, we delve into the global reach of the miscreants involved in credential theft and the blackhat tools they rely on. We observe a remarkable lack of external pressure on bad actors, with phishing kit playbooks and keylogger capabilities remaining largely unchanged since the mid-2000s.},
