Question 110
A browser warns about a malicious shortlink yet workers repeatedly enter corporate credentials after clicking it. Before changing security policy, what evidence should the engineer examine FIRST?
Explanation
Correct Answer
Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. This checks the relevant condition before an engineer modifies production access or detection behavior. A secure email channel and DNS/web controls reduce exposure but cannot certify that every newly registered domain is benign. The controlled response would be: Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. Situation: A browser warns about a malicious shortlink yet workers repeatedly enter corporate credentials after clicking it.
Incorrect Answers
Inspect business assets and trust boundaries, control coverage, failure paths, enforcement logs, and incident recovery dependencies. This evidence addresses Defense in depth and Cisco SAFE; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. Situation: A browser warns about a malicious shortlink yet workers repeatedly enter corporate credentials after clicking it.
Inspect source provenance, attempted instruction overrides, allowed tool verbs, prompt isolation, and server-side authorization results. This evidence addresses Prompt injection trust boundary; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. Situation: A browser warns about a malicious shortlink yet workers repeatedly enter corporate credentials after clicking it.
Review message authentication results, sender/domain similarities, original contact directory, transaction changes, and escalation records. This evidence addresses Business email compromise verification; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. Situation: A browser warns about a malicious shortlink yet workers repeatedly enter corporate credentials after clicking it.
