A. B. C. D.B.
The correct answer is B. Encryption.
Ransomware is a type of malware that encrypts the victim's files or entire computer system and demands payment, usually in cryptocurrency, in exchange for the decryption key. Encryption is the primary evasion technique employed by ransomware, as it makes it difficult for security software to detect and prevent the malware from executing.
Encryption is the process of converting plaintext data into a scrambled ciphertext using an algorithm and a secret key. The ciphertext can only be decrypted with the correct key, which is held by the attacker. Ransomware typically uses strong encryption algorithms such as AES to encrypt the victim's files, making it virtually impossible to decrypt without the key.
In addition to encryption, ransomware may also employ other evasion techniques such as obfuscation, polymorphism, and anti-analysis techniques to evade detection and analysis by security software. However, encryption remains the primary technique used by ransomware to evade detection and prevent victims from recovering their data without paying the ransom.
