For example, a loadable kernel module (LKM) rootkit can be utilized to monitor and report activities on the ECU, after the attacker gets inside an ECU. Not all cyber threats are as easy to detect and remove as, say, Trojan horses. This means that memory rootkits will inevitably affect the performance of your computer’s RAM. After gathering more experience in the field, I started making my own projects, based on the Arduino µC. Unlike application rootkits, kernel mode rootkits are among the most severe types of this threat as they target the very core of your operating system.

There are several types of rootkits, each targeting a different part of your computer. A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or areas of its software that would not otherwise be allowed (for example, to an unauthorized user) while at the same time masking its existence or the existence of other software. Understanding Attackers' Motives And while it had the ability to access and steal data, it specialized in recruiting computer systems into a network that was designed to be used by hackers. Rootkit's name suggests that it is a set of canned attack scripts for obtaining root access. User-mode rootkits are relatively easy to detect because they operate at the same layer as anti-virus programs. The rootkit may be one or a set of more than one programs that work together to open a backdoor for hackers. User-mode or application rootkit – These are installed in a shared library and operate at the application layer, where they can modify application and API behavior.

A user mode rootkit works by infecting the files of common applications like Paint, Excel and Notepad. For example, the rootkit may hide an application that spawns a shell when the attacker connects to a particular network port on the system. While firmware rootkits are normally developed for the main processing board, they can also be developed for I/O that can be attached to the asset. The first line of defense is reducing the surface of attack by using a modern operating system that implements countermeasures against rootkits.
