Though most 419 scams are perpetrated by e-mail alone, some scammers enhance the believability of their offer through the use of a sham website. Such websites can imitate real sites such as eBay, PayPal or a banking site like Bank Of America for the purposes of phishing, while others are totally fictional and used to lend credibility to a scammer’s story. For example, a scammer may create a website for a fictional bank, then give the victim details to login to the site, where the victim then sees the money that the scammer has promised sitting in the account. The victim is then more likely to believe the scammer and send the requested advance payments. Fake websites are the centerpiece of false online storefront scams.
Another twist on scamming involves providing links to real news sites covering events the scammer says are relevant to the transaction they propose. For instance, a scammer may use news of the death of a prominent government official as a backstory for a scam involving getting millions of dollars of the slain official’s money out of the country. These are real websites covering legitimate news, but the scammer is usually not connected in any way with the events reported, and is simply using the story to gain the victim’s sympathy.
