'As part of his scheme, Coker bid in multiple auctions for vehicles and jewelry on the GSA Auctions website. When Coker won a particular auction, he was directed to the pay.gov website to remit payment in the amount of his winning bid. Instead of remitting payment in the amount of his winning bid, Coker breached the pay.gov website and falsified the true auction price to $1."

If you read further, it does not sound like he actual breached the site, he just changed the amount paid and their incompetence marked it paid.
