Why coronavirus scammers can send fake emails from real domains

Organizations like the WHO could prevent domain spoofing, but many don’t.

That “open protocol” means that the email transmission system itself doesn’t verify the identity of senders. Instead, senders and receivers have had to organize voluntary authentication methods: Domain owners can adopt an ID system, and email providers can check for for those IDs. But participation has not been universal on both sides. 

“There are just so many organizations that don’t authenticate their mail. So if you are interested in tricking someone, that becomes an incredibly useful vector to do so,” said Kalember.
