WHY DO THESE PEOPLE WANT YOUR E-MAIL ADDRESS?
Are you familiar with these cyber nasties?
• Phishing – spam emails (often very authentic-looking) that appear to be from a bank, finance provider or retailer. These messages hope to get lucky and direct you to fake websites.
• Pharming – spoof sites that hijack legitimate domain names to lure unsuspecting consumers, collecting credit card numbers, account names and passwords along the way.
• Crimeware – these programs capture information directly from users' PCs using keystroke loggers. They can go largely unnoticed but for a slight slowdown in computer performance.
These people will steal your money; don't give them your E-mail address.
