An email says you missed an important phone call and must click a link or open an attachment to listen to your voicemail.
Access voicemail through your normal phone or voicemail system, not an unexpected email link.
An email says you missed an important phone call and must click a link or open an attachment to listen to your voicemail.
The attachment is usually an HTML file that opens a fake Microsoft login in your browser. Because it's a local file, URL filters never see it.
If you already clicked and signed in: change that password now, from the real site, and turn on multi-factor authentication. If you sent money, call your bank immediately; wire and ACH recalls work best in the first hours. Tell your IT provider so they can check for forwarding rules and other sign-ins on the account.
OpenEFA MailGuard blocks most of these before they reach an inbox. The ones that get through are usually the most carefully targeted, which is why your people still need to know the pattern.
