Where Did That Scammer Get Your Email Address?

You’ve seen the emails: They purport to have been sent by some dethroned prince in a faraway land, or from a corrupt bureaucrat in an equally corrupt government. Whatever the ruse, they always claim to need your help in spiriting away millions of dollars. These schemes, known as “419,” “advance fee” and “Nigerian letter” scams, have been around forever and are surprisingly effective at duping people. But where in the world do these scammers get their distribution lists, and how did you become a target?

Some of the bigger spammers rely on bots that crawl millions of Web sites and “scrape” addresses from pages. Others instead turn to sellers on underground cybercrime forums. But as it turns out, there are still a handful of open-air markets where lists of emails are sold by the millions. If you buy in bulk, some you can expect to pay about a penny per 1,000 addresses.

One long-running, open air bazaar for email addresses is LeadsAndMails.com, which also goes by the name BuyEmails.org. This enterprise is based out of New Delhi, India, and advertises its email lists as “100% optin and 100 percent legal to use.” I can’t vouch for the company’s claims, but one thing seems clear: A good number of its clients are from Nigeria, and many of them are fraudsters.

The number of consumer and financial records compromised as a result of data breaches in 2010 fell dramatically compared to previous years, a shift that cybercrime investigators attribute to a sea-change in the motives and tactics used by criminals to steal information. At the same time, organizations are dealing with more breaches than ever before, and most data thefts continue to result from security weaknesses that are relatively unsophisticated and easy to prevent.

The U.S. Justice Department and the FBI this week were granted unprecedented authortiy to seize control over a criminal botnet that enslaved millions of computers and to use that control to disable the malicious software on infected PCs.

The target of the takedown was “Coreflood,” an infamous botnet that first emerged almost a decade ago as a high-powered virtual weapon designed to knock targeted Web sites offline. Over the years, the crooks running the botnet began using it to defraud owners of the victim PCs by stealing bank account information and draining balances.

Scammers typically kick into high gear during tax season in the United States, which tends to bring with it a spike in phishing attacks that spoof the Internal Revenue Service. Take, for example, a new scam making the rounds via email, which warns of discrepancies on the recipient’s income tax return and requests that personal information be sent via fax to a toll-free number.

Who controlled the Rustock botnet? The question remains unanswered: Microsoft’s recent takedown of the world’s largest spam engine offered tantalizing new clues to the identity and earnings of the Rustock botmasters. The data shows that Rustock’s curators made millions by pimping rogue Internet pharmacies, but also highlights the challenges that investigators still face in tracking down those responsible for building and profiting from this complex crime machine.

Business gurus have long maintained that time = $, but that doesn’t mean playtime necessarily detracts from the bottom line. As many corporations have discovered, employees tend to be more productive when they have time to give their brains a break, and gameplay is the perfect escape. So it’s not surprising that some cyber criminals have taken this lesson to heart, and are crafting crime machines to include games that allow them to steal money and set hi-scores at the same time.
