An online service boldly advertised in the cyber underground lets miscreants hire accomplices in several major U.S. cities to help empty bank accounts, steal tax refunds and intercept fraudulent purchases of high-dollar merchandise.
An increasing number of services offered in the cybercrime underground allow miscreants to purchase access to hacked computers at specific organizations. For just a few dollars, these services offer the ability to buy your way inside of Fortune 500 company networks.
This blog has featured several stories on reshipping scams, which recruit willing or unwitting U.S. citizens (“mules”) to reship abroad pricey items that are paid for with stolen credit cards. Today’s post highlights a critical component of this scheme: the black-market sale of international shipping labels fraudulently purchased from the U.S. Postal Service.
In February, I published the results of an investigation into the identity of the man behind the once-infamous Srizbi spam botnet. Today’s post looks at the individual(s) likely involved in running the now-defunct Xarvester botnet, a spam machine that experts say appeared shortly after Srizbi went offline and shared remarkably similar traits.
Srizbi was also known in the underground as “Reactor Mailer,” and customers could register to spam from the crime machine by logging into accounts at reactormailer.com. That domain was registered to a mserver@mail.ru, an address that my reporting indicates was used by a Philipp Pogosov; more commonly known by his nickname SPM, Pogosov was a top moneymaker for SpamIt, a rogue online pharmacy affiliate program that was responsible for a huge percentage of junk email over the past half-decade.
A new service offered in the cybercriminal underground is geared toward spammers, scammers and malware purveyors interested in mass-registering dozens of dodgy domains in one go.
Employee and financial records leaked from some of the world’s largest sponsors of spam provide new clues about the identity of a previously unknown Russian man believed to have been closely tied to the development and maintenance of “Bredolab,” a massive collection of hacked machines that was disassembled in an international law enforcement sweep in late 2010.
In October 2010, Armenian authorities arrested 27-year-old Georg Avanesov on suspicion of running Bredolab, a botnet that infected an estimated 3 million PCs per month through virus-laden e-mails and booby-trapped Web sites. The arrest resulted from a joint investigation between Armenian police and cyber sleuths in the Netherlands, whose ISPs were home to at least 143 servers used to direct the botnet’s activities.
Underground Web sites can be a useful barometer for the daily volume of criminal trade in goods like stolen credit card numbers and hijacked PayPal or eBay accounts. And if the current low prices at one of Underweb’s newer and… Read More »
A Wikileaks-style war of attrition between two competing rogue Internet pharmacy gangs has exposed some of the biggest spammers on the planet. The latest casualties? Several individuals likely responsible for running Grum, currently the world’s most active spam botnet.
Microsoft on Monday named a Russian man as allegedly the guy responsible for running the Kelihos botnet, a spam engine that infected an estimated 40,000 PCs. But closely held data seized from the world’s largest spam affiliate program suggests that the driving force behind Kelihos is a different individual who is still coordinating spam campaigns for hire.
Kelihos shares a great deal of code with the infamous Waledac botnet, a far more pervasive threat that infected hundreds of thousands of computers and pumped out tens of billions of junk emails promoting shady online pharmacies. Despite the broad base of shared code between the two malware families, Microsoft classifies them as fundamentally different threats. The company used clever legal techniques to seize control over and shutter both botnets, sucker punching Waledac in early 2010 and taking out Kelihos last fall.
On Monday, Microsoft filed papers with a Virginia court stating that Kelihos was run by Andrey N. Sabelnikov, a St. Petersburg man who once worked at Russian antivirus and security firm Agnitum. But according to the researcher who shared that intelligence with Microsoft — and confidentially with Krebs On Security weeks prior to Microsoft’s announcement — Sabelnikov is likely only a developer of Kelihos. Rather, the researcher argues, the true coordinator of both Kelihos and Waledac is another Russian man who is well known to anti-spam activists.
Given the heightened security surrounding air travel these days, it may be hard to believe that fraudsters would try to board a plane using stolen tickets. But incredibly, there are a number of criminal travel agencies doing business in the underground, and judging from the positive feedback left by patrons, business appears to be booming.
The tickets often are purchased at the last minute and placed under the criminal buyer’s real name. The reservations are made using either stolen credit cards or hijacked accounts belonging to independent contractors in the travel industry. Customers are charged a fraction of the cost of the tickets and/or reservations, typically between 25 and 35 percent of the actual cost.
