![]() When a rootkit installer program is given access to be installed on a user’s PC, it secretly hides itself until activated by a hacker. They basically hide in software that may appear to be genuine and could provide genuine functions. Rootkits rely on clandestine methods to infect computers, as they cannot spread by themselves. They can even infect your BIOS (the part of your computer that is independent of the OS), making them difficult to remove. Generally, rootkits go much deeper than the normal virus. All users should be aware of the threat they pose. Rootkits basically provide access to all your folders through administrative powers, allowing the hacker to do whatever they want with your computer. You may also be experiencing a rootkit infection if you observe unusually high CPU usage or slow performance. Unusual occurrences like background images changing or disappearing in the lock screen or pinned items changing on the taskbar are signs of a rootkit infection. Another symptom is when Windows settings change without any apparent action by the user. This eventually indicates that there is an active rootkit infection. One common sign of a rootkit infection is that anti malware protection stops working. Because of this, rootkit developers aim at keeping their malware undetectable, meaning there may not be too many symptoms that flag a rootkit infection. There are also instances in which the rootkit installation may still depend on security vulnerabilities, but in others, the malware could get installed as part of an evidently genuine application or file on the USB drive.Ī rootkit primarily focuses on hiding in order to remain installed and accessible on the targeted system. In this method, attackers leave USB drives with rootkits hidden on them in places where victims can easily pick them up, such as coffee shops and office buildings. The exploit code for a particular vulnerability can be hosted on a genuine website that has been compromised.Īnother rootkit infection method is via infected USB drives. ![]() This is followed by installing the rootkit and setting up components that permit remote access to the computer. Attackers target known vulnerabilities in the OS and applications and make use of the exploit code to obtain a special position on the target machine. The most common is by using a vulnerability in the operating system or an application running on the computer. Several different methods are used for installing rootkits. Establishing or enhancing stealth, making it complicated for security analysts and most anti malware products to detect the malware that the rootkit is designed to protect.Providing an attacker with ongoing full access, mostly through backdoors.Allowing the malware to bear reboots and removal attempts by anti malware and other tools.Concealing other malware that cybercriminals may later install as part of a sustained attack.Escalating the privilege level in which the malware operates.The spread of this malicious software has increased the development of rootkit scanner tools, which are used for regularly scanning your device and removing rootkits with the help of rootkit removal software. ![]() A rootkit permits attackers to obtain access to and steal data from a user’s device without being detected for long periods of time.
