These hackers have limited or no training and know how to use only basic techniques or tools. What kind of hackers are we talking about?

Black-Hat Hackers are malicious, unauthorized attackers who typically possess significant technical skills, which contradicts the description of limited or no training.

Script Kiddies is the technically accurate answer for individuals with limited training who rely on pre-existing tools rather than original techniques - this choice should be the correct answer per the question stem.

White-Hat Hackers are authorized security professionals who ethically test systems with permission; however, this category does not align with the question's description of individuals with limited or no training who rely only on basic tools. The provided correct answer appears to contain an error, as Script Kiddies is the universally accepted term for low-skill attackers who use pre-built exploits without deep technical knowledge.

Gray-Hat Hackers operate in an ethical middle ground, sometimes accessing systems without authorization but without malicious intent, and generally possess moderate to advanced technical skills.
