Online Casino Falls Victim to EBay Sniper Trap

Share Article

Iraq Museum International uses files still posted on eBay to recreate minute-by-minute how an eBay "sniper trap" cheated an online casino.

A leader in online gaming is among the latest victims of fraud on eBay. The online casino fell prey this week to a "sniper trap," involving a bidder's retraction and two phony bids.

The casino was the winning bidder in a highly-publicized eBay auction of a candy wrapper which ended on August 12, 2005.

While monitoring online auction sites for the sale of illegal artifacts, Iraq Museum International ( recognized in the candy wrapper auction a pattern it had been studying. Its line-by-line analysis of the auction's bidding history, still posted on eBay, shows that the casino was cheated by the actions of at least one other bidder.


1. On August 6, 2005, the high bid was $705 placed by a bidder using the ID "terrestrial_seti."

2. On August 7, 2005, the same day a press release was issued about the sale, a bidder using the alias "keepitbidding" placed a $3,000 bid on the candy wrapper.

3. This action triggered automatic bidding on behalf of "terrestrial_seti" up to the secret maximum set by "terrestrial_seti" the day before.

4. After placing the $3,000 bid, "keepitbidding" could see that "keepitbidding" had the high bid at $1,411. "Keepitbidding" could now calculate that "terrestrial_seti" had a secret maximum of $1,406.

5. Working quickly, "keepitbidding" filled out a bid retraction form giving eBay the excuse, "Entered wrong amount." The retraction was automatically executed just 52 seconds after the $3,000 bid was placed by "keepitbidding."

6. One minute later, "keepitbidding" placed a new bid on the same item, this time in the amount of exactly $1,400, knowing that this would be automatically outbid by "terrestrial_seti."

7. The ruse worked. EBay's automatic bidding system bid $1,405 out of the account of "terrestrial_seti," just one dollar short of that bidder's maximum. As a result, the high bid suddenly doubled. Like a wild fluctuation in the stock market, this heightened bidder interest in the item, drawing thousands of visits to the auction listing.

8. Undetected on a high-publicity day this scam touched off a bidding war which led to the casino placing a winning bid of $2,815.43 for the item.

The online casino is the kind of "mark" targeted by such auction manipulation. It is known for aggressively bidding on unique items on eBay such as the tatooing rights to a woman's forehead and a grilled cheese sandwich reportedly carrying the image of the Blessed Virgin Mary.

The auction's bidding history reveals one of the longest lists of bid retractions or cancellations in eBay's history. A total of 10 bids ranging from $710 to $8,000 were cancelled by either the bidder or the seller.

This case study is a continuation of Iraq Museum International's bulletin on "sniper traps" and other practices on eBay, as it formulates its recommendations to the antiquities market and monitors the Internet for sales of artifacts stolen from Iraq.
