IP address at all times. Which of the following should the technician use?

• • A. Cryptominer

• • B. Phishing

• • C. Ransomware

• • D. Keylogger

When a user receives a message stating that files are encrypted and cannot be accessed, it is likely that ransomware has infected the computer. Cryptominers are malware that use a victim's computing resources to mine cryptocurrency. Phishing is a social engineering attack that tricks victims into providing sensitive information. Keyloggers are malware that record a user's keystrokes to steal login credentials or other sensitive information.
