Question 710
A telephone caller impersonates a helpdesk employee and demands a one-time authentication code. Which method should the assessment team select for this precise requirement?
Explanation
Correct Answer
Classify the attempt as vishing and teach independent callback verification. This answer directly addresses the described constraint. Voice pretexts can solicit secrets or bypass verification procedures. Successful validation requires: A trained employee refuses the request and uses an approved callback number.
Incorrect Answers
This action applies to a different case: A tester proposes scraping discarded sensitive papers from an office dumpster after physical scope ended. Dumpster diving is physical reconnaissance and is not implied by web authorization. It does not establish the present requirement, where a trained employee refuses the request and uses an approved callback number. The appropriate action is: Classify the attempt as vishing and teach independent callback verification.
That approach concerns a different situation: a compromised community website frequently used by a particular department redirects users to unsafe content. Trusted browsing habits can expose targeted groups to hostile sites. The required result is that a trained employee refuses the request and uses an approved callback number. The appropriate action is: Classify the attempt as vishing and teach independent callback verification.
That relates to a different issue: A client wants a social-engineering platform to deliver simulated emails at low volume. Dedicated tools can manage controlled phishing simulation and reporting. That is not a direct remedy for the requested outcome: A trained employee refuses the request and uses an approved callback number. The appropriate action is: Classify the attempt as vishing and teach independent callback verification.
