Multiple choice

What is a zero-day exploit?

  1. A type of cyberattack that targets a vulnerability that is not yet known to the software vendor.

  2. A type of cyberattack that targets a vulnerability that is already known to the software vendor.

  3. A type of cyberattack that targets a vulnerability that is not yet known to the general public.

  4. A type of cyberattack that targets a vulnerability that is already known to the general public.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A zero-day exploit is a type of cyberattack that targets a vulnerability that is not yet known to the software vendor. This means that the software vendor has not yet had a chance to release a patch to fix the vulnerability.

Multiple choice

What is the significance of zero-day exploits?

  1. They can be used to compromise systems that are not protected by a patch.

  2. They can be used to bypass security measures.

  3. They can be used to steal sensitive data.

  4. All of the above.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Zero-day exploits can be used to compromise systems that are not protected by a patch, bypass security measures, and steal sensitive data. This makes them a very dangerous type of cyberattack.

Multiple choice

How do zero-day exploits work?

  1. They take advantage of a vulnerability in a software program.

  2. They exploit a flaw in a hardware device.

  3. They use social engineering to trick users into giving up their passwords.

  4. They use a combination of the above methods.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Zero-day exploits work by taking advantage of a vulnerability in a software program. This vulnerability allows the attacker to execute arbitrary code on the victim's system.
