The term 'trojan' comes from Greek mythology and the story of the Trojan Horse. In the tale,
Greek soldiers hid inside a large wooden horse and presented it as a gift to the Trojans. The
Trojans, who were fond of horses, trusted the gift and brought it into their city. At night, the
soldiers emerged from the horse and attacked the city from within.
Spyware
Spyware is malware designed to secretly monitor a user’s activities and send the collected
information to a hacker. It doesn’t spread by itself but is often delivered by Trojans, viruses, or
worms. Once installed, spyware remains hidden to avoid detection.
Ransomware
Ransomware is a type of malicious software that encrypts data on a computer, making it
inaccessible. To regain access to their data, the victim must pay a large sum of money to the
attacker, similar to paying a ransom for a kidnapped person.
Rootkit
A rootkit is malware that gains administrator access to the host system. Once access is gained,
the rootkit hides but retains special access, making it hard to detect because it can bypass
security software.
Backdoor
A backdoor is a type of malicious software that sneaks into a computer bundled with other
software or files. It allows attackers to gain remote access to the host computer.
