Week 8 EOC

What is the problem with SPAM?I hate spam. Most spam is irritating and time-consuming, but some spam is positively dangerous to handle. Usually email scams are trying to get you to give up your bank details so that the fraudsters can either withdraw money, or steal your identity. Embedded HTML 'bugs' may offer your personal info to marketers, and could carry viruses. Although seasoned network administrators may have grown accustomed to the nuisance of unsolicited e-mail, or spam, these messages may soon pose severe security threats, thanks to emerging software geared to give e-marketers more access to personal data. Marketing companies have begun to embed invisible HTML "bugs" or "beacons" in their e-mail. Because these tiny one-pixel images must be retrieved from the sender's server when the message is opened, they can tell the sender when and how often a recipient looks at a message. HTML makes browsers launch, and the senders can place cookies on every PC that accepts the e-mail message with a bug. As a result, those cookies allow the sender to gather information such as the recipient's IP address, the type of browser they use, and the Web sites they visit. This is extremely dangerous, and computer users need to beware of the dangers of spam.
