Have you ever wondered- where does the term “rootkit” comes from? In Unix and Linux operating systems (OS), the system admin, there is an all-powerful account with full privileges and access with no restrictions (similar to the administrator account in Windows). We call the account- “root”. Moreover, the applications that allow unauthorized root/admin-level access to the device and restricted areas, we refer them as- “kit”.

So, put the two together, you will get “rootkit”. In other words, a rootkit is a program that lets someone with legitimate or malicious intent privilege access a computer or mobile device. Through this, the person can now control the device remotely without the owner’s knowledge or consent.

Unfortunately, rootkits allow creating unauthorized access to computers. It aids cybercriminals in stealing personal data and financial information, install malware, or use computers as part of a botnet. The purpose is to circulate spam and participate in DDoS (distributed denial-of-service) attacks.

Lastly, imagine a burglar who wants to break in and steal from your home. They often dress in black to blend into the darkness and move quietly. However, unlike the thief who takes something and leaves immediately, a rootkit sticks around in your computer. It will eventually rob your data or manipulating what’s inside the computer over time.
