OCR GCSE Computer Science Complete Practice Exam 2026

Question: 1 / 400

What is being tested during a Zero-day Attack?

Software vulnerabilities post-release

Potential malware threats

Software before its release

A Zero-day Attack specifically refers to an attack that exploits a software vulnerability that is unknown to the vendor or the public at the time of the attack. Hence, it highlights vulnerabilities that exist after a software has been released but before a fix is made available, which is why the correct answer focuses on software vulnerabilities post-release.

In the context of Zero-day Attacks, options that deal with potential malware threats, software before its release, or network traffic patterns do not accurately capture the essence of a Zero-day Attack. While these aspects are important in a broader cybersecurity context, they do not directly address the concept of exploiting unpatched vulnerabilities in existing software that are being targeted during a Zero-day Attack.
