Which item is listed as a threat to IT systems today?

• A. Insiders
• B. Nation-State Actors
• C. Botnets
• D. Malicious Code

Answer: (D)

Threats to IT systems today come in many forms, and malicious code is a central danger. Malicious code refers to software designed to harm, steal data, or take control of devices. It includes viruses, worms, trojans, ransomware, spyware, and other malware. Because it can spread quickly across networks, evade basic defenses, and compromise data, confidentiality, and operations, it remains one of the most encountered threats across organizations. Attackers deploy it through phishing emails, drive-by downloads, infected software, or compromised supply chains, enabling broader attacks and lasting impact. While insiders pose risk due to legitimate access, and nation-state actors or botnets are real threats, malicious code is the mechanism that makes many of these threats possible, making it the most representative answer for threats to IT systems today.
