Ethical Hacking Essentials Practice Test

A camouflage virus is a type of malware that specifically uses the same filename as a legitimate target program. This tactic helps it blend in with normal system processes, increasing the chances that a user will unknowingly execute the virus when attempting to run the legitimate program. By masquerading as a trusted application, the camouflage virus can effectively spread and execute its payload while avoiding detection.

Worms operate by self-replicating and typically spread across networks without the need for user intervention, focusing on network transmission rather than disguising themselves as legitimate files. Trojan horses also often deceive users by appearing as harmless or beneficial software but do not necessarily use the same filename as the target program. Rootkits are more focused on hiding certain processes or files from the operating system, often allowing other malware to function undetected, rather than masquerading as legitimate executables.

In summary, the key characteristic of the camouflage virus is its reliance on adopting the same filename as the target application, which is an essential trait for its function in executing malicious code without alerting the user.
