What is Rootkit in Cybersecurity?
Malware designed to hide its presence and maintain persistent, privileged access to a compromised system. Rootkits modify the operating system kernel, bootloader, or firmware to conceal malicious processes, files, and network connections from administrators and security tools.
Why Rootkit Matters for Your Cybersecurity Career
Rootkits represent some of the most dangerous threats in cybersecurity because they are extremely difficult to detect and remove. Incident responders may need to rebuild infected systems entirely since rootkits survive standard cleanup. Security engineers deploy secure boot and kernel integrity monitoring to prevent rootkit installation. Malware analysts reverse-engineer rootkits to develop detection signatures.
