Ransomware is delivered in two common ways: phishing emails and drive-by downloads. The first method intends to convince the user to click on malicious links or attachments. In the second method, the malicious code automatically downloads from the Internet, runs without the user’s consent, and infects the computer system!!
What is a ransomware attack?
It is a type of malware that enters the system without the user’s knowledge and encrypts the data. The victim needs to pay a ransom to get the decryption key for encrypted data files. If he does not give a ransom, the files remain unavailable to the victim.
It adds a unique extension like .xyz, .xxx, .encrypted to data files within each drive. These encrypted files start displaying instructions on how to pay the ransom for a decryption key. It attempts to spread to the connected nodes (computers, storage media) after the initial infection.
