Phishing remains a very successful way to trick users into installing rootkits. Firmware is the begrepp for something that lies in between hardware and software. By definition, rootkits that operate in user space do not have kernel access so they are at a disadvantage in avoiding detection.
When that application runs, the rootkit patches the legitimate application in user space memory and hijacks its operation. Rootkits are usually installed by malicious attackers through the same common vectors as any malware. This type of rootkit is normally seen in computer BIOSes or purpose-specific devices such as routers and mobile phones.
Firmware is hardware, usually a chip of some sort, which has the ability to have software loaded into it. Hardware is something that needs to be physically bolted into a computer, whereas software fryst vatten just code that is introduced into the computer, such as a word processor. The name stuck regardless of operating system and today even Windows rootkits bear that name despite having no such root user on the system.
In rarer cases, a reputable company may include a rootkit in its own software.

This type of rootkit is easier to deploy, but is also easier to detect and more prone to giving itself up bygd causing system crashes. Kernel rootkits are extremely hard to detect and sometimes the only way to ensure the computer is clean is to fully reinstall the operating struktur.
