Cybersecurity-Practitioner Cybersecurity Fundamentals Practice Question
During a simulated phishing exercise, an employee clicks a link in an email that directs them to a credential-harvesting page mimicking the corporate single sign-on portal. According to the common attack lifecycle, which phase immediately follows this successful credential capture?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use of valid accounts for initial access or lateral movement
After obtaining valid user credentials through phishing, the adversary enters the credential access phase and typically moves to lateral movement or initial access using those compromised credentials.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use of valid accounts for initial access or lateral movement
Why this is correct
Stolen credentials are subsequently used for initial access or lateral movement within the environment.
- ✗
Exploitation of client-side software vulnerabilities
Why it's wrong here
Exploitation occurs when a vulnerability is targeted, which is not required when valid credentials are stolen via social engineering.
- ✗
Passive network sniffing to harvest additional certificates
Why it's wrong here
Harvesting credentials directly skips the need for passive network sniffing at that exact stage.
- ✗
Immediate domain controller encryption via ransomware
Why it's wrong here
Ransomware deployment is typically the final objective, which happens much later after reconnaissance and privilege escalation.
