What can be categorized as malicious code?

1. Antivirus software

2. Ransomware

3. Application software

4. Firmware updates

The correct answer is: Ransomware

Malicious code refers to software designed to harm, exploit, or otherwise compromise the integrity of an individual's or organization's data or systems. Ransomware is classified as malicious code because it encrypts a victim's files and demands a ransom payment for the decryption key, effectively holding the data hostage. This type of software is specifically created with the intent to cause damage, disrupt operations, or extract money from victims, aligning perfectly with the definition of malicious code. Antivirus software operates to detect and neutralize harmful threats, making it a protective measure rather than malicious itself. Application software encompasses a wide range of programs that can be used for legitimate purposes. Firmware updates are essential for maintaining and improving the security and functionality of hardware devices, rather than exhibiting harmful characteristics. As such, they do not fall under the category of malicious code.
