There are numerous new communications options available, and along with this explosion of new technology a new wave of unsolicited messages has also arrived.

That’s where their money is made, by pushing offers to unsuspecting people. If the content was to change too much, the commercial intent might be lost in the translation. For this reason, spam filters which focus on message content are generally the most effective.
“Phishing emails” are a huge vector of threat, and content-based filtering attempts to eliminate these emails totally.

They generally have dire sounding titles like “Attention Required,” “Last Warning.” or something similar. They prey on the fears of the recipient, warning them of a dire consequence for not responding.
Once the victim opens the attachment or clicks on the link in the email, they’re sent to a website that resembles the one that’s being spoofed. They’re asked to give up more information, such as their account information or password. If they do, they’ve just give control of extremely important information to a criminal enterprise.
