Before interacting with any file in your inbox, always perform a quick visual and contextual audit. 1. Analyze the Context and Content
Unexpected Context: Be highly suspicious of unsolicited documents, even if they appear to come from a known contact.

Spoofed Senders: Attackers frequently swap or omit characters in the domain string. Hover your cursor over the display name to reveal the actual, underlying email address. 2. Inspect File Extensions
