Quick History Lesson:
- The first electronic mail system was created by Ray Tomlinson in 1971, using CPYNET. He came up with the idea of the @ symbol.

- In the 1980’s, the World Wide Web was developed, and the first email software, Lotus Notes, was released.
- Gmail, the most popular email service today, was released in 2004.
- In 1978, Gary Thuerk carried out a marketing campaign via electronic mail. The email was sent to 400 email addresses on ARPANET, and is considered the first-ever spam email.
- The infamous ‘ILOVEYOU’ worm was released in 2000, infecting approximately 10 million computers worldwide. The worm was spread via a Visual Basic script, attached to an email. Once the victim opened the attached script, duplicates of the email were sent to all contacts, and the hard disk got corrupted.
- From 2013 to 2015, Evaldas Rimasauskas stole over $120 milion (about ₦94 billion) from Facebook and Google via a Business Email Compromise (BEC) scheme.
