‘Carderprofit’ Forum Sting Nets 26 Arrests

June 26, 2012

The U.S. Justice Department today unveiled the results of a two-year international cybercrime sting that culminated in the arrest of 26 people accused of trafficking in hundreds of thousands of stolen credit and debit card accounts. Among those arrested was an alleged core member of “UGNazi,” a malicious hacking group that has claimed responsibility for a flood of recent attacks on Internet businesses.

The carding forum Carderprofit.cc was an FBI sting operation.

Federal officials are calling the operation the largest coordinated international law enforcement action in history directed at “carding” crimes, in which the Internet is used to traffic in and exploit the stolen credit card, bank account and other personal information of hundreds of thousands of victims.

According to documents released by the Justice Department, the sting — dubbed “Operation Card Shop” — began in June 2010, when the FBI established an undercover carding forum called “CarderProfit” (carderprofit.cc) to identify users who were buying and selling stolen credit card accounts and goods purchased with stolen accounts.

The FBI kept track of Internet addresses used by forum members, and used members’ login information to gather additional information about registered users. The agency tightened the noose in May 2012, when it began imposing new membership requirements to restrict site membership to individuals with established knowledge of carding techniques or interest in criminal activity.

“For example, at times, new users were prevented from joining the site unless they were recommended by two existing users who had registered with the site, or unless they paid a registration fee,” the government said in a statement about today’s arrests. “New users registering with the [undercover] site were required to provide a valid e- mail address as part of the registration process. The e-mail addresses entered by registered members of the site were collected by the FBI.”

Carderprofit.cc as it appears now.

Meanwhile, the feds were collecting stolen credit and debit card accounts that were being traded by forum members, and feeding the information back to issuing banks. The Justice Department said it contacted affected financial institutions regarding more than 411,000 compromised credit and debit cards, and notified 47 companies, government entities, and educational institutions of the breach of their networks.

Bank Settles With Calif. Cyberheist Victim

June 26, 2012

A California escrow firm that sued its bank last year after losing nearly $400,000 in a 2010 cyberheist has secured a settlement that covers the loss and the company’s attorneys fees. The settlement is notable because such cases typically favor the banks, and litigating them is often prohibitively expensive for small- to mid-sized businesses victimized by these crimes.

In March 2010, organized computer crooks stole $465,000 from Redondo Beach, Calif. based Village View Escrow Inc., sending 26 consecutive wire transfers from Village View’s accounts to 20 individuals around the world who had no legitimate or previous business with the firm. The escrow firm clawed back some of the stolen funds — $72,000 — but that still left Village View with a $393,000 loss, forcing the company’s owner to take out a personal loan at 12 percent interest to cover the loss of customer funds).

In June 2011, Village View sued its financial institutionProfessional Business Bank — arguing that the bank was negligent because it protected customer accounts solely with usernames and passwords. Last week, Village View announced that it had reached a settlement with its bank to recover more than just the full amount of the funds taken from the account plus interest for Village View Escrow.

Kim Dincel, a shareholder at Silicon Valley Law Group, which represented the plaintiffs, said the Uniform Commercial Code and its corresponding California Commercial Code limits the damages resulting from wire transfer fraud to only the actual amount of money lost plus interest – nothing more.  Common law claims such as negligence, breach of contract and fraud, and the damages that attached to them, are generally precluded from being asserted by a victim of wire transfer fraud in a lawsuit involving wire transfer fraud, he added.

“Banks typically deny liability for the cyber-theft which forces small businesses to spend money they do not have on legal fees and regulatory expenses in order to recover a limited and defined set of damages under the Uniform Commercial Code (UCC),” Dincel said in a prepared statement released Monday.

The Bank of Manhattan, which acquired Professional Business Bank last month, did not return calls seeking comment.

How to Break Into Security, Ptacek Edition

June 25, 2012

At least once a month, sometimes more, readers write in to ask how they can break into the field of computer security. Some of the emails are from people in jobs that have nothing to do with security, but who are fascinated enough by the field to contemplate a career change. Others are already in an information technology position but are itching to segue into security. I always respond with my own set of stock answers, but each time I do this, I can’t help but feel my advice is incomplete, or at least not terribly well-rounded.

I decided to ask some of the brightest minds in the security industry today what advice they’d give. Almost everyone I asked said they, too, frequently get asked the very same question, but each had surprisingly different takes on the subject. Today is the first installment in a series of responses to this question. When the last of the advice columns have run, I’ll create an archive of them all that will be anchored somewhere prominently on the home page. That way, the next time someone asks how they can break into security, I’ll have more to offer than just my admittedly narrow perspectives on the matter.

Last month, I interviewed Thomas Ptacek, founder of Matasano Security, about how companies could beef up password security in the wake of a week full of news about password leaks at LinkedIn and other online businesses. Ptacek’s provocative advice generated such a huge amount of reader interest and further discussion that I thought it made sense to begin this series with his thoughts:

Ptacek: “Information security is one of the most interesting, challenging, and, if you do it carefully, rewarding fields in the technology industry. It’s one of the few technology jobs where the most fun roles are well compensated. If you grew up dreaming of developing games, the laws of supply and demand teach a harsh lesson early in your career: game development jobs are often tedious and usually pay badly. But if you watched “Sneakers” and ideated a life spent breaking or defending software, great news: infosec can be more fun in real life, and it’s fairly lucrative. Continue reading

PharmaLeaks: Rogue Pharmacy Economics 101

June 22, 2012

Consumer demand for cheap prescription drugs sold through spam-advertised Web sites shows no sign of abating, according to a new analysis of bookkeeping records maintained by three of the world’s largest rogue pharmacy operations.

Researchers at the University of California, San Diego, the International Computer Science Institute and George Mason University examined caches of data tracking the day-to-day finances of GlavMed, SpamIt, and Rx-Promotion, shadowy affiliate programs that over a four-year period processed more than $170 million worth of orders from customers seeking cheaper, more accessible and more discretely available drugs. The result is perhaps the most detailed analysis yet of the business case for the malicious software and spam epidemics that persist to this day.

Their conclusion? Spam — and all of its attendant ills — will remain a prevalent and pestilent problem because consumer demand for the products most frequently advertised through junk email remains constant.

“The market for spam-advertised drugs is not even close to being saturated,” said Stefan Savage, a lead researcher in the study, due to be presented early next month at the 21st USENIX security conference in Bellevue, Wash. “The number of new customers these programs got each day explains why people spam: Because sending spam to everyone on the planet gets you new customers on an ongoing basis, so it’s not going away.”

The researchers found that repeat customers are critical to making any rogue pharmacy business profitable. Repeat orders constituted 27% and 38% of average program revenue for GlavMed and SpamIt, respectively; for Rx-Promotion, revenue from repeat orders was between 9% and 23% of overall revenue.

“This says a number of things, and one is that a lot of people who bought from these programs were satisfied,” Savage said. “Maybe the drugs they bought had a great placebo effect, but my guess is these are satisfied customers and they came back because of that.”

Whether the placebo effect is something that often applies with the consumption of erectile dysfunction drugs is not covered in this research paper, but ED drugs were by far the largest category of pills ordered by customers of all three pharmacy programs.

One interesting pattern that trickled out of the Rx-Promotion data underscores what made this pharmacy affiliate unique and popular among repeat buyers: A major portion of its revenues was generated through the sale of drugs that have a high potential for abuse and are thus tightly controlled in the United States, including opiates and painkillers like Oxycodone, Hydrocodone, and mental health pills such as Adderall and Ritalin. The researchers noticed that although pills in this class of drugs — known as Schedule II in U.S. drug control parlance — comprised just 14 percent of orders for Rx-Promotion, they accounted for nearly a third of program revenue, with the Schedule II opiates accounting for a quarter of revenue.

“The fact that such drugs are over-represented in repeat orders as well (roughly 50 percent more prevalent in both Rx-Promotion and, for drugs like Soma and Tramadol, in SpamIt) reinforces the hypothesis that abuse may be a substantial driver for this component of demand,” the researchers wrote.

A Closer Look: Email-Based Malware Attacks

June 21, 2012

Nearly every time I write about a small- to mid-sized business that has lost hundreds of thousands of dollars after falling victim to a malicious software attack, readers want to know how the perpetrators broke through the victim organization’s defenses, and which type of malware paved the way. Normally, victim companies don’t know or disclose that information, so to get a better idea, I’ve put together a profile of the top email-based malware attacks for each day over the past month.

Top malware email attacks in past 30 days. Source: UAB

This data draws from daily reports compiled by the computer forensics and security management students at the University of Alabama at Birmingham, a school I visited last week to give a guest lecture and to gather reporting for a bigger project I’m chasing. The UAB reports track the top email-based threats from each day, and include information about the spoofed brand or lure, the method of delivering the malware, and links to Virustotal.com, which show the percentage of antivirus products that detected the malware as hostile.

As the chart I compiled above indicates, attackers are switching the lure or spoofed brand quite often, but popular choices include Amazon.com, the Better Business Bureau, DHL, Facebook, LinkedIn, PayPal, Twitter and Verizon Wireless.

Also noticeable is the lack of antivirus detection on most of these password stealing and remote control Trojans. The average detection rate for these samples was 24.47 percent, while the median detection rate was just 19 percent. This means that if you click a malicious link or open an attachment in one of these emails, there is less than a one-in-five chance your antivirus software will detect it as bad.

Beware Scare Tactics for Mobile Security Apps

June 20, 2012

It may not be long before your mobile phone is beset by the same sorts of obnoxious, screen-covering, scaremongering ads pimping security software that once inundated desktop users before pop-up blockers became widely-used.

A mobile ad for SnapSecure's software

Richard M. Smith, a Boston-based security consultant, was dining out last Friday and browsing a local news site with his Android-based smart phone when his screen was taken over by an alarming message warning of page errors and viruses. Clicking anywhere on the ad took him to a Web site peddling SnapSecure, a mobile antivirus and security subscription service that bills users $5.99 a month.

“This particular ad takes over the entire screen on my Android phone, so it gives the impression of being rather ominous,” Smith said, noting that it was the second time in as many days that he’d encountered the rogue ad. He further explained that the ad just appeared when he browsed to view a new story, and that he hadn’t clicked on an ad or anything unusual.

Michael Subhan, vice president of marketing for SnapSecure, said the company traced the ads back to some rogue marketing affiliates that have since been banned from its advertising program.

“We did find out which affiliate was serving up the ad, and they will be blacklisted from the network,” Subhan said. “We have strict advertising policies, and do not tolerate rogue affiliates. Unfortunately, with the volume of advertising that we do, there are sometimes affiliates that try and get around our guidelines.”

Meanwhile, the ad linked to in the overlay image still appears to be live and redirecting users to the SnapSecure purchase page.

Naming and Shaming the Plaintext Offenders

June 15, 2012

It was a fitting end to a week dominated by news of password breaches at major Internet companies. I’d sent a password reset request to a hosting provider I’ve used for years to host a file server online, and received an alarming response: The company sent me my password in plain text, all but advertising that they have zero regard for the security of their customers’ private information.

The site was used to store inconsequential files and images, but I cancelled my subscription nonetheless because the company’s response to my password reset request proved that they were storing my password without even making the weakest attempts at encrypting the information or storing it in a protected format.

Sadly, this practice appears to be quite common, particularly among low-cost hosting providers. I confronted the company, Hosting Metro, about its practices, but received no material response to my complaints aside from an automated “sorry to see you go” email.

I also submitted a redacted screen shot of the password reset email to plaintextoffenders.com, a site that regularly posts user-submitted images of password reset emails from companies that exhibit a complete lack of regard for customer password security. I would encourage all readers to do the same for any site that sends passwords in the clear.

Like many previous visitors to plaintextoffenders.com, I was surprised to see that the site’s search function does not work. The administrators of the forum seem to be aware of this, and have noted that visitors can search by company name via Google, by using the search convention “site:plaintextoffenders.com” followed by a Web site or company name. I would welcome the development of a browser plugin that uses a database of offending sites to warn users when they visit a site that practices unforgivably sloppy password security. Naming and shaming may be the only way to change this all-too-common practice.

Apple, Oracle Ship Java Security Updates

June 13, 2012

There must have been some rare planetary alignment yesterday, because the oddest thing happened: Apple and Oracle both shipped software updates for the same Java security flaws on the very same day.

I’ve taken Apple to task several times for its unacceptable delays in patching Java vulnerabilities. Oracle is the official producer of Java, but Apple maintains its own version, and it has consistently lagged months behind Oracle in fixing security bugs. This failure on Apple’s part finally caught up with Mac OS X users earlier this year and turned into a major embarrassment for Apple, when the Flashback malware infected more than 650,000 Mac systems using a vulnerability that Oracle (but not Apple) had patched roughly two months earlier.

Well, it seems that Apple learned a thing or two from that incident. The update Oracle released yesterday, Java 6 Update 33 and Java 7 Update 5, fixes at least 14 security flaws in the oft-attacked software that is installed on more than three billion devices worldwide. Apple’s Java update brings Java on the Mac to 1.6.0_33, and patches 11 of the 14 security vulnerabilities that Oracle fixed in Tuesday’s release. It’s unclear whether those other three flaws simply don’t exist in the Mac version of Java, but we’ll take progress where we can get it.

Regardless of which operating system you use, if you have Java installed, I would advise you to update it, neuter it or remove it as soon as possible. The reason I say this is that Java requires constant patching, and it appears to be the favorite target of attackers these days. Continue reading

Who Is the ‘Festi’ Botmaster?

June 13, 2012

Pavel Vrublevsky, the co-founder of Russian payment processor ChronoPay, is set to appear before a judge this week in a criminal case in which he is accused of hiring a botmaster to attack a competitor. Prosecutors believe that the man Vrublevsky hired in that attack was the curator of the Festi botnet, a spam-spewing machine that also has been implicated in a number of high-profile denial-of-service assaults.

Igor Artimovich

Vrublevsky spent six months in prison last year for his alleged role in an attack against Assist, the company that was processing payments for Aeroflot, Russia’s largest airline. Aeroflot had opened its contract for processing payments to competitive bidding, and ChronoPay was competing against Assist and several other processors.

Investigators with the Russian Federal Security Service (FSB) last summer arrested a St. Petersburg man named Igor Artimovich in connection with the attacks. Artimovich — known in hacker circles by the handle “Engel” — confessed to having used his botnet to attack Assist after receiving instructions and payment from Vrublevsky.

As I wrote in last year’s piece, the allegations against Artimovich and Vrublevsky were supported by evidence collected by Russian computer forensics firm Group-IB, which assisted the FSB with the investigation. Group-IB presented detailed information on the malware and control servers used to control more than 10,000 infected PCs, and shared with investigators screen shots of the botnet control panel (pictured below) allegedly used to coordinate the DDoS attack against Assist.

Group-IB’s evidence suggested Artimovich had used a botnet he called Topol-Mailer to launch the attacks, but Topol-Mailer is more commonly known as Festi, one of the world’s largest and most active spam botnets. As detailed by researchers at NOD32 Antivirus makers ESET, Festi was built not just for spam, but to serve as a very powerful tool for launching distributed denial of service (DDoS) attacks, digital sieges which use hacked machines to flood targets with so much meaningless traffic that they can no longer accommodate legitimate visitors.

“Topol Mailer” botnet interface allegedly used by Artimovich.

Group-IB said Artimovich’s botnet was repeatedly used to attack several rogue pharmacy programs that were competing with Rx-Promotion, a rogue Internet pharmacy affiliate program long rumored to have been co-founded by Vrublevsky (security firm Dell SecureWorks chronicled those attacks last year).

Artimovich allegedly used the nickname Engel on Spamdot.biz, an online forum owned by the co-founders of SpamIt and GlavMed, sister rogue pharmacy operations that competed directly with Rx-promotion. In the screen shot below right, Engel can be seen communicating with Spamdot member and SpamIt affiliate “Docent.” That was the nickname used by Oleg Nikolaenko, a 24-year-old Russian man arrested in Las Vegas in Nov. 2010  charged with operating the Mega-D botnet.

Microsoft Patches 26 Flaws, Warns of Zero-Day Attack

June 12, 2012

Microsoft today released updates to plug at least 26 separate security holes in its Windows operating systems and related software. At the same time, Microsoft has issued a stopgap fix for a newly-discovered flaw that attackers are actively exploiting.

The security fixes are included in seven security patch bundles, three of which earned Microsoft’s most dire “critical” label, signifying that attackers can exploit them without any help on the part of the user.  Redmond patched vulnerabilities in Windows, Internet Explorer, Dynamics AX, Microsoft Lync (Microsoft’s enterprise instant message software), and the Microsoft .NET Framework.

Microsoft called out two patches as particularly important: the Internet Explorer bundle (MS12-037), which addresses 13 issues; and a critical flaw in the Windows remote desktop protocol (RDP). Updates are available for all supported versions of Windows, via Windows Update or Automatic Update. Continue reading
