Many of these attacks begin with<u> spam</u> , which is defined as unsolicited messages that are usually sent in massive numbers using electronic mail systems. A spam <u>filter</u> uses a set of rules to examine email messages and determine which are spam. There are four common types of spam filters.<u> Content </u>filters examine the content within a message for certain words or phrases commonly used in spam emails.<u> Header</u> filters review the email header for falsified information, such as spoofed IP addresses. <u>Blacklist</u> filters block mail that originates from IP addresses of known spammers. <u>Permission </u> filters block or allow mail based on the sender's address. <u>Phishing</u> is an email scam that masquerades as a message from a(n) legitimate company or agency of authority, such as the IRS. <u>Pharming</u> redirects Web site traffic to fraudulent Web sites that distribute malware, collect personal data, sell counterfeit products, and perpetrate other scams. A rogue <u>antivirus </u> exploit usually begins with a virus warning and an offer to disinfect the infected device. Some software is not exactly malware, but it is a nuisance.
