Sample Questions
Q1) How does a rootkit work?
Answer: One approach used by rootkits is to alter or replace operating system files with modified versions that are specifically designed to ignore malicious activity. For example, on a computer the anti-malware software may be instructed to scan all files in a specific directory and in order to do this, the software will receive a list of those files from the operating system. A rootkit will replace the operating system's ability to retrieve a list of files with its own modified version that ignores specific malicious files. The anti-malware software assumes that the computer will willingly carry out those instructions and retrieve all files; it does not know that the computer is only displaying files that the rootkit has approved.
Q2) What is a worm?
Answer: A worm is a malicious program designed to take advantage of a vulnerability in an application or an operating system in order to enter a computer. Once the worm has exploited the vulnerability on one system, it immediately searches for another computer that has the same vulnerability. A worm uses a network to send copies of itself to other devices also connected to the network.
