Question 570
A compromised user sends phishing internally but the team looks only for malware files on endpoints. The team believes no other action is necessary. Why is the current tenant configuration inadequate for this requirement?
Explanation
Correct Answer
The actual failure mechanism is Email account compromise can propagate through collaboration workflows without a detected local malware file. Its relevance follows from the stated tenant facts, not just a generic security recommendation. Correct it by investigate Defender for Office 365 email entities, sender behavior and related Defender XDR incident data. Then verify: The report links the compromised sender to suspicious outbound messages and affected recipients.
Incorrect Answers
Phishing simulations must not expose passwords to uncontrolled third-party services. The stated symptoms instead indicate that email account compromise can propagate through collaboration workflows without a detected local malware file.
Security notification workflows must meet their own data-sharing and privacy requirements. The stated symptoms instead indicate that email account compromise can propagate through collaboration workflows without a detected local malware file.
SPF authorization alone cannot establish that a display name represents the claimed executive. The stated symptoms instead indicate that email account compromise can propagate through collaboration workflows without a detected local malware file.
