What is Spam and who Sends it?
Spam is the use of media to send bulk unsolicited messagesThe recipient has not opted to receive the message. Although most spam comes in the form of emails, it also can be found in instant messaging, forum posting, blog posting, SMS, social media (e.g Facebook, Myspace & Twitter) and even still the old fashion way of postal and fax spam. Any way you can be contacted, you can be spammed.
Why do Spammers Spam?
For next to no cost, spammers can send out messages to hundreds of millions of people. Their efforts are rewarded even if just one or two people click on their link, buy their product or more frighteningly, give out their private details.
With improved technology and widespread internet access, spam is now a widely used medium for committing crimes including financial institution fraud, credit card fraud, and identity theft, among others.
Spam can also act as a stepping stone to accessing computers and servers without authorization, and sending out maliciuos links that direct to a website usually hosted by the spammer with the sole purpose of downloading malicious material onto the user's computer without their consent. Usually the malware & viruses are used to create the infamous 'Botnet', giving the sender control of a large group of computers, using them to send out further spam and malicious material.
Who is Behind Spam?
Spammers can come in many shapes and forms, starting with the single person who buys an email list from a third party, to the top end full-time illicit spammers, who have groups of people in countries worldwide, sending unsolicited email to hundreds of millions of people 24 hours a day.
