Linux Kernel Keyloggers and Information Security

This research paper aims to build and explore a Linux kernel module capable of logging keystrokes that a user would make on a Linux-based system. The module captures credentials which is a process known as keylogging. The kernel of the operating system manages all resources and data, and a breach in this area is a serious information security risk. This paper provides substantial evidence that kernel-level keyloggers are a very serious risk to information security in operating systems and computer systems in general. Such keyloggers can log user information, such as passwords, usernames and other information without much of the user's knowledge.
