A cybersecurity analyst is investigating a potential breach where an attacker gained unauthorized access to a server by exploiting an unpatched vulnerability in its operating system. Which of the following best describes the attacker's initial method of gaining access?
- ASocial Engineering
- BDenial of Service
- CVulnerability Exploitation
- DMalware Infection
Show answer & explanationAnswer & explanation
Correct answer: C. Vulnerability Exploitation
Vulnerability exploitation refers to an attacker leveraging a known weakness or flaw in software or hardware to gain unauthorized access or perform malicious actions.
Why the other options are wrong
- A. Social engineering manipulates individuals into performing actions or divulging confidential information, which is not described here.
- B. Denial of Service attacks aim to make a service unavailable to legitimate users, not to gain unauthorized access.
- D. Malware infection involves software designed to disrupt, damage, or gain unauthorized access to a computer system, but the initial access here is via a vulnerability.
Vulnerability Exploitation
The act of taking advantage of a security flaw or weakness in a system, application, or network to achieve an unauthorized outcome.
- Requires a pre-existing vulnerability (e.g., unpatched software, misconfiguration).
- Often uses an 'exploit code' designed to trigger the vulnerability.
- Can lead to unauthorized access, privilege escalation, or data compromise.
- Patch management is a key defense against this attack method.
