A form of cyber attack in which a user is tricked into thinking that an email came from a trusted source.
The Long Explanation
A technique used in phishing attacks where a hacker sends an email that has been contrived to look like it was sent by a trusted source.
Email spoofing is a popular technique used in phishing and spam attacks because people tend to open an email when they believe that it is from someone or a company they know or trust.
A most recent example of a large email spoofing phishing attack was the one that victimized the users of OpenSea – the largest NFT marketplace. Seventeen users lost a total of 250 NFTs, which were worth approximately $2 million.
Apparently, the attackers knew about a scheduled update, and that OpenSea would be sending out emails with instructions on the same. They created fake emails with links to fake OpenSea web pages, which resulted in users losing their NFTs.
