New Bot-Powered eBay Scam Uncovered: Page 2 of 4

(eBay typically contains several hundred one-cent items such as ebooks, Windows wallpaper images, or digital photos, all delivered electronically so there is no shipping cost.)

Ironically, most sellers of one-cent items also use bots to power their sales -- it would economically unfeasible to do so manually -- that automatically e-mails the purchase to the buyer, then posts a standard, and positive, feedback on the buyer's profile.

It's the sales history, and more important, the positive feedback, that the cyber crooks are after.

"Once they have 15 or 20 feedback items, they can use that account to set up bogus auctions," said Guillaume Lovet, the leader of Fortinet's virus research team in Europe and the discoverer of the scam. "They can set up an auction for an MP3 player, start the bidding at $35 or so, and run a short auction so that it's less likely buyers will look at the details of the account's feedback."

When the buyer of the purported MP3 player doesn't receive his hardware and complains to eBay, the only recourse eBay offers is to shut down the seller's account. By that time the scammer's moved on to another fake account.
