There are multiple devices that emit radio waves. The most obvious is are radiod and microwaves (yes, the food cooker). Wireless applicances also emit radio waves.

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.
