You discover malware has corrupted the BIOS on your laptop. Which type of malware is this?

Question

Options

• Abootkit
• Bexploit
• Crootkit
• Dvulnerability

• A
  94% (34)
• C
  3% (1)
• D
  3% (1)

Explanation

A (bootkit) is correct because a bootkit is a specific type of malware that targets and infects low-level firmware or the boot process - including the BIOS/UEFI - allowing it to persist even through OS reinstalls and antivirus scans.

• B (exploit) is wrong: an exploit is a technique or piece of code that takes advantage of a vulnerability - it's a method of attack, not a category of malware.
• C (rootkit) is wrong: rootkits hide malicious activity within the operating system (kernel/user space), not the BIOS/firmware layer specifically. While some advanced rootkits overlap with bootkits, the term "rootkit" alone doesn't imply BIOS corruption.
• D (vulnerability) is wrong: a vulnerability is a weakness in a system that can be exploited - it's not malware at all.

Memory tip: Think bootkit = attacks the boot process/BIOS. If the malware survives before the OS even loads, it's a bootkit.
