To duplicate and spread to additional machines, they take advantage of weaknesses in a network or system.

3. Trojans Trojan horses are dangerous programs that masquerade as trustworthy programs.

They can carry out a variety of damaging tasks, such stealing data or giving an attacker control over the infected system, but they cannot replicate on their own.

4. Ransomware Files that have been encrypted by ransomware are demanded to be decrypted in exchange for a ransom payment.

It is not recommended to pay the ransom because doing so encourages more criminal activity and doesn’t ensure the release of your files.
