Half of All ‘Rogue’ Pharmacies at Two Registrars

March 12, 2012

Half of all “rogue” online pharmacies — sites that sell prescription drugs without requiring a prescription — got their Web site names from just two domain name registrars, a study released today found. The findings illustrate the challenges facing Internet policymakers in an industry that is largely self-regulated and rewards companies who market their services as safe havens for shadowy businesses.

There are about 450 accredited domain name registrars worldwide, but at least one-third of all active rogue pharmacy sites are registered at Internet.bs, a relatively small registrar that purports to operate out of the Bahamas and aggressively markets itself as an “offshore” registrar. That’s according to LegitScript, a verification and monitoring service for online pharmacies.

LegitScript President John Horton said the company began to suspect that Internet.bs was courting the rogue pharmacy business when it became clear that the registrar has only two-tenths of one percent of the market share for new Web site name registrations. In a report (PDF) being released today, LegitScript said that a separate analysis of more than 9,000 “not recommended” pharmacies compiled by the National Association of Boards of Pharmacy suggested that Internet.bs is sponsoring nearly 44 percent of the Internet’s dodgy pill shops.

Asked whether he was concerned about allegations that his firm was targeting an industry that seeks out registrars who turn a blind eye to questionable businesses, Internet.bs President Marco Rinaudo replied that, on the contrary, LegitScript’s report was bound to be “excellent advertising for our company.”

Reached via phone at his home in Panama, Rinaudo said he was under no obligation to police whether his customers’ business may be in violation of some other nation’s laws, absent clear and convincing evidence that his registrants were operating illegally from their own country.

“Even though I understand they could bother some pharmacy lobby, if an industry likes us, what’s the problem with an online pharmacy, as long as they are operating legally from their own country?” Rinaudo asked. “We cannot accept pressure to shut down a legitimate business just because it is not pleasing to some political lobbying group. We and I personally make sure that all the domains that are in breach of an applicable law and for which we receive a complete report, will be acted on the same day.”

Banking on Badb in the Underweb

March 8, 2012

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 more brazen card shops are indicative of a trend, the market for these commodities has never been more cutthroat.

Visa, Amex cards for sale at Badb.su

Badb.su is distinguishable from dozens of underground carding shops chiefly by its slick interface and tiny domain name, which borrows on the pseudonym and notoriety of the Underweb’s most recognizable carder. It’s difficult to say whether “Badb” himself would have endorsed the use of his brand for this particular venture, but it seems unlikely: The man alleged by U.S. authorities to be Badb — 29-year-old Vladislav Anatolievich Horohorin — has been in a French prison since his arrest there in 2010. Authorities believe Horohorin is one of the founding members of CarderPlanet, a site that helped move millions of stolen accounts. He remains jailed in France, fighting extradition to the United States (more about his case in an upcoming story).

Badb.su’s price list shows that purloined American Express and Discover accounts issued to Americans cost between $2.50 and $3 apiece, with MasterCard and Visa accounts commanding slightly lower prices ($2-$3). Cards of any type issued by banks in the United Kingdom or European Union fetch between $4-$7 each, while accounts from Canadian financial institutions cost between $3 to $5 a pop.

The site also sells verified PayPal and eBay accounts. Verified PayPal accounts with credit cards and bank accounts attached to them go for between 2-3$, while the same combination + access to the account holder’s email inbox increases the price by $2. PayPal accounts that are associated with bank and/or credit accounts and include a balance are sold for between 2 and 10 percent of the available balance. That rate is considerably lower than the last PayPal underground shop I reviewed, which charged 8 to 12 percent of the total compromised account balance.

Verified PayPal accounts with positive balances sell for between 2-10% of the available balance.

Ebay auction accounts are priced according to the number of positive “feedback” points that each victim account possesses (feedback is the core of eBay’s reputation system, whereby members evaluate their buying and selling experiences with other members). eBay accounts with fewer than 75 feedback history sell for $2 each, while those with higher levels of feedback command prices of $5 and higher apiece, because these accounts are more likely to be perceived as trustworthy by other eBay members.

But don’t count on paying for any of these goods with a credit card; Badb.su accepts payment only through virtual currencies such as Liberty Reserve and WebMoney.

Badb.su, like many other card shops, offers an a-la-carte, card-checking service that allows buyers to gauge the validity of stolen cards before or after purchasing them. Typically, these services will test stolen card numbers using a hijacked merchant account that initiates tiny charges or so-called pre-authorization checks against the card; if the charge or pre-auth clears, the card-checking service issues a “valid” response for the checked card number.

Court: 4 More Months for DNSChanger-Infected PCs

March 6, 2012

Millions of PCs sickened by a global computer contagion known as DNSChanger were slated to have their life support yanked on March 8. But an order handed down Monday by a federal judge will delay that disconnection by 120 days to give companies, businesses and governments more time to respond to the epidemic.

The reprieve came late Monday, when the judge overseeing the U.S. government’s landmark case against an international cyber fraud network agreed that extending the deadline was necessary “to continue to provide remediation details to industry channels approved by the FBI.”

Adobe Patches Critical Flash Flaws

March 5, 2012

For the second time in less than a month, Adobe has issued an update to fix dangerous flaws in its Flash Player software. The patch addresses two vulnerabilities rated “critical,” but Adobe says it is not aware of active attacks against either flaw.

The fixes being released today address a pair of critical bugs that are present in Adobe Flash Player 11.1.102.62 and earlier versions for Windows, Mac, Linux and Solaris, Flash Player v 11.1.115.6 and earlier versions for Android 4.x, and Flash Player 11.1.111.6 and earlier versions for Android 3.x and 2.x. Adobe says both flaws in today’s release were reported by Google security researchers.

For Windows, Mac, Linux and Solaris users, the newest version is 11.1.102.63, and is available through the Player Download Center. To find out which version of Flash you have installed, visit this page. Users can grab the latest version from the Adobe Flash Player Download Center, although if you’re not careful to untick the check box next to whatever “optional” goodies Adobe tries to bundle with Flash Player (the most common is McAfee Security Scan Plus) you could end up with more than you wanted.

Windows users who browse the Web with Internet Explorer and another browser may need to apply the Flash update twice, once using IE and again with the other browser. Chrome normally auto-updates Flash – often hours or days before the fixes are publicly released for download — although for some reason I still had the vulnerable version 11.1.102.62 installed when Adobe’s security advisory was released today. According to the Chrome Releases blog, Google began pushing out an update last night that includes the new Flash version.

Today’s update comes close on the heels of a critical Flash patch that closed at least seven security holes, including one that was at the time already being exploited to break into vulnerable systems (that one, also, was reported by Google).

Many readers have reported site slowness or availability issues over the past several days. My site has been receiving some extra love in the form of automated junk traffic. Apologies for the inconvenience, and thanks for your patience while we work things out.

PSI 3.0: Auto-Patching for Dummies

February 28, 2012

A new version of the Personal Software Inspector (PSI) tool from vulnerability management firm Secunia automates the updating of third-party programs that don’t already have auto-updaters built-in. The new version is a welcome development for the sort of Internet users who occasionally still search their keyboards for the “any” key, but experienced PSI users will probably want to stick with the comparatively feature-rich current version.

PSI 3.0 Beta's simplified interface.

PSI 3.0 introduces one major new feature: Auto-updating by default. The program installs quickly and immediately begins scanning installed applications for missing security updates. When I ran the beta version, it found and automatically began downloading and installing fixes for about half of the apps that it detected were outdated. The program did find several insecure apps that it left alone, including iTunes, PHP and Skype; I suspect that this was based on user feedback. It may also just avoid auto-patching busy programs (all three of those applications were running on my test machine when I installed PSI 3.0); for these, PSI presents the “run manual update,” or “click to update,” option.

But users familiar with previous versions of PSI may be frustrated with the beta version’s intentional lack of options. The beta is devoid of all settings that are present in the current version of PSI, and the user dashboard that listed updated software alongside outdated programs and other options no longer exists. In fact, once a program is updated, it is removed from the update panel, leaving no record of what was updated (I had to sort my Program Files folder by date to learn which programs were touched after running PSI 3.0).

Feds Request DNSChanger Deadline Extension

February 22, 2012

Extradition of Accused Masterminds Moves Forward

Millions of computers infected with the stealthy and tenacious DNSChanger Trojan may be spared a planned disconnection from the Internet early next month if a New York court approves a new request by the U.S. government. Meanwhile, six men accused of managing and profiting from the huge collection of hacked PCs are expected to soon be extradited from their native Estonia to face charges in the United States.

DNSChanger modifies settings on a host PC that tell the computer how to find Web sites on the Internet, hijacking victims’ search results and preventing them from visiting security sites that might help detect and scrub the infections. The Internet servers that were used to control infected PCs were located in the United States, and in coordination with the arrest of the Estonian men in November, a New York district court ordered a private U.S. company to assume control over those servers. The government argued that the arrangement would give ISPs and companies time to identify and scrub infected PCs, systems that would otherwise be disconnected from the Internet if the control servers were shut down. The court agreed, and ordered that the surrogate control servers remain in operation until March 8.

But earlier this month, security firm Internet Identity revealed that the cleanup process was taking a lot longer than expected: The company said more than 3 million systems worldwide — 500,000 in the United States — remain infected with the Trojan, and that at least one instance of the Trojan was still running on computers at 50 percent of Fortune 500 firms and half of all U.S. government agencies. That means that if the current deadline holds, millions of PCs are likely to be cut off from the Web on March 8.

In a Feb. 17 filing with the U.S. District Court for the Southern District of New York, officials with the U.S. Justice Department, the U.S. Attorney for the Southern District of New York, and NASA asked the court to extend the March 8 deadline by more than four months to give ISPs, private companies and the government more time to clean up the mess. The government requested that the surrogate servers be allowed to stay in operation until July 9, 2012. The court has yet to rule on the request, a copy of which is available here (PDF).

Not everyone thinks extending the deadline is the best way to resolve the situation. In fact, security-minded folks seem dead-set against the idea. KrebOnSecurity conducted an unscientific poll earlier this month, asking readers whether they thought the government should give affected users more time to clean up infections from the malware, which can be unusually difficult to remove. Nearly 1,400 readers responded that forcing people to meet the current deadline was the best approach. The overwhelming opinion (~9:1) was against extending the March 8 deadline.

KrebsOnSecurity readers voted almost 9-1 against the idea of extending the Mar. 8 deadline.

In related news, the six Estonian men arrested and accused of building and profiting from the DNSChanger botnet are expected to be extradited to face computer intrusion and conspiracy charges in the United States.  Continue reading

How Not to Buy Tax Software

February 22, 2012

Scott Henry scoured the Web for a good deal on buying tax preparation software. His search ended at Blvdsoftware.com, which advertised a great price and an instant download. But when it came time to install the software, Henry began to have misgivings about the purchase, and reached out to KrebsOnSecurity for a gut-check on whether trusting the software with his tax information was a wise move.

Five days after Henry purchased the product, blvdsoftware.com vanished from the Internet.

Several red flags should have stopped him from making the purchase. Blvdsoftware.com claimed it had been in business since 2005, but a check of the site’s WHOIS registration records showed it was created in late October 2011. The site said that Blvdsoftware was a company in Beverly Hills, Calif., but the California Secretary of State had no record of the firm, and Google Maps knew nothing of the business at its stated address.

Henry said that in years past, he’d always bought a CD version of the software. But this year, he opted for digital download.

“I was going to download from Amazon — they sell a download-only version — and then I saw the cheaper site and went with them,” he said in an email. He installed the program, but said he didn’t enter any of his sensitive data. For one thing, he never received a license key from Blvdsoftware, and the program he installed didn’t request one. Now he’s wondering if the program was — at the very least pirated — and at worst — bundled with software designed to surreptitiously snoop on his computer.

Zeus Trojan Author Ran With Spam Kingpins

February 17, 2012

The cybercrime underground is expanding each day, yet the longer I study it the more convinced I am that much of it is run by a fairly small and loose-knit group of hackers. That suspicion was reinforced this week when I discovered that the author of the infamous ZeuS Trojan was a core member of Spamdot, until recently the most exclusive online forum for spammers and the shady businessmen who support the big spam botnets.

Thanks to a deep-seated enmity between the owners of two of the largest spam affiliate programs, the database for Spamdot was leaked to a handful of investigators and researchers, including KrebsOnSecurity. The forum includes all members’ public posts and private messages — even those that members thought had been deleted. I’ve been poring over those private messages in an effort to map alliances and to learn more about the individuals behind the top spam botnets.

The Zeus author’s identity on Spamdot, selling an overstock of “installs.”

As I was reviewing the private messages of a Spamdot member nicknamed “Umbro,” I noticed that he gave a few key members his private instant message address, the jabber account bashorg@talking.cc. In 2010, I learned from multiple reliable sources that for several months, this account was used exclusively by the ZeuS author to communicate with new and existing customers. When I dug deeper into Umbro’s private messages, I found several from other Spamdot members who were seeking updates to their ZeuS botnets. In messages from 2009 to a Spamdot member named “Russso,” Umbro declares flatly, “hi, I’m the author of Zeus.”

Umbro’s public and private Spamdot postings offer a fascinating vantage point for peering into an intensely competitive and jealously guarded environment in which members feed off of each others’ successes and failures. The messages also provide a virtual black book of customers who purchased the ZeuS bot code.

In the screen shot above, the ZeuS author can be seen selling surplus “installs,” offering to rent hacked machines that fellow forum members can seed with their own spam bots (I have added a translation beneath each line). His price is $60 per 1,000 compromised systems. This is a very reasonable fee and is in line with rates charged by more organized pay-per-install businesses that also tend to stuff host PCs with so much other malware that customers who have paid to load their bots on those machines soon find them unstable or unusable. Other members apparently recognized it as a bargain as well, and he quickly received messages from a number of interested takers.

The image below shows the Zeus author parceling out a small but potentially valuable spam resource that was no doubt harvested from systems compromised by his Trojan. In this solicitation, dated Jan. 2008, Umbro is selling a mailing list that would be especially useful for targeted email malware campaigns.

Flash Player Update Nixes Zero-Day Flaw

February 15, 2012

Adobe has issued a critical security update for its ubiquitous Flash Player software. The patch plugs at least seven security holes, including one reported by Google that is already being used to trick users into clicking on malicious links delivered via email.

In an advisory released Wednesday afternoon, Adobe warned that one of the flaws — a cross-site scripting vulnerability (CVE-2012-0767) reported by Google —  was being used in the wild in active, targeted attacks designed to trick users into clicking on a malicious link delivered in an email message. The company said the flaw could be used to take actions on a user’s behalf on any website or webmail provider, if the user visits a malicious website. A spokesperson for the company said this particular attack only works against Internet Explorer on Windows.
