People rely on email to do a wide array of tasks. We use it to sign up for websites, apply for jobs, make payments, get in touch with friends and family, and many more. However, email is also commonly exploited by hackers to steal information or launch malware attacks.

Users get around 200 emails in their inbox a day, including work messages, automated payment slips, and everyone’s least favorite email, spam. Spam messages are mostly harmless, but when you get more than 10,000 of them flooding your inbox, you’re probably the victim of a special type of spam attack.
