Internet's underground economy is worth $5 billion

Internet fraud has become a multi-billion dollar business with thieves stealing bank account information and credit card numbers and then selling them online.

Hi-tech thieves who specialize in card fraud have a credit line in excess of $5bn, research by the world’s largest maker of security software, Symantec, suggests .

Symantec calculated the figure to quantify the scale of fraud it found during a year-long look at the internet’s underground economy , according to reports.

Credit card numbers were the most popular item on sale and made up 31% of all the goods on offer. Coming in second were bank details which made up 20% of the items being offered on criminal chat channels. The $5.3bn figure was reached by multiplying the average amount of fraud perpetrated on a stolen card, $350, by the many millions Symantec observed being offered for sale. Similarly, the report said, if hi-tech thieves plundered all the bank accounts offered for sale they could net up to $1.7bn.

Symantec said it was likely that many of the cards offered for sale were invalid or cancelled and bank accounts closed but it added: “These figures are indicative of the value of the underground economy and the potential worth of the market.”

Credit card numbers have proved so popular among hi-tech thieves because they are easy to obtain and use for fraudulent purposes. Many of the methods favoured by cyber criminals, such as phishing schemes, database attacks and magnetic strip skimmers, are designed to steal credit card information , it said.

The existence of a ready market for any stolen data and the growing use of credit cards also helped maintain their popularity, it said.

“High frequency use and the range of available methods for capturing credit card data would generate more opportunities for theft and compromise and, thus, lead to an increased supply on underground economy servers,” said the report.

The price card thieves can expect for the numbers they offer for sale also varied by the country of origin. US card numbers were the cheapest because they were so ubiquitous — 74% of all cards offered for sale were from the US. By contrast numbers from cards issued in Europe and the Middle East commanded a premium because they were relatively rare.
