Suspicious Email Activity

EASY50 points29 solves

During ongoing monitoring of a suspicious online persona, analysts intercepted an email believed to be associated with the same individual previously observed sharing public activity data.

The message does not appear to be a typical phishing attempt, but may indicate involvement in unauthorized access to external systems.

Initial review suggests the email may have originated from infrastructure unrelated to the sender’s claimed identity.

Your task is to analyze the email metadata, identify the true origin of the message, and determine where the email was sent from.
