‘White Label’ Money Laundering Services

August 4, 2014

Laundering the spoils from cybercrime can be a dicey affair, fraught with unreliable middlemen and dodgy, high-priced services that take a huge cut of the action. But large-scale cybercrime operations can avoid these snares and become much more profitable when they’re able to disguise their operations as legitimate businesses operating in the United States, and increasingly they are doing just that.

The typical process of "cashing out" stolen credit card accounts.

The typical process of “cashing out” stolen credit card accounts.

Today’s post looks at one such evolution in a type of service marketed to cybercrooks that has traditionally been perhaps the most common way that thieves overseas “cash out” cybercrimes committed against American and European businesses, banks and consumers: The reshipping of goods purchased through stolen credit cards.

Cybercrooks very often rely on international reshipping services to help move electronics and other goods that are bought with stolen credit cards, shipped abroad, and then sold for cash. Many fraudsters use stolen credit cards to pay for U.S. Postal Service and FedEx shipping labels — a.k.a. “black labels” — but major shipping providers appear to be getting better at blocking or intercepting packages sent with stolen credit cards (at least according to anecdotal evidence from the cybercrime forums).

As a result, crooks increasingly are turning to a more reliable freight: So-called “white label” shipping services that are paid for with cybercrime-funded bank accounts via phony but seemingly legitimate companies in the United States. Continue reading

Sandwich Chain Jimmy John’s Investigating Breach Claims

July 31, 2014

Sources at a growing number of financial institutions in the United States say they are tracking a pattern of fraud that indicates nationwide sandwich chain Jimmy John’s may be the latest retailer dealing with a breach involving customer credit card data. The company says it is working with authorities on an investigation.

jjohnsMultiple financial institutions tell KrebsOnSecurity that they are seeing fraud on cards that have all recently been used at Jimmy John’s locations.

Champaign, Ill.-based Jimmy John’s initially did not return calls seeking comment for two days. Today, however, a spokesperson for the company said in a short emailed statement that “Jimmy John’s is currently working with the proper authorities and investigating the situation. We will provide an update as soon as we have additional information.”

The unauthorized card activity witnessed by various financial institutions contacted by this author is tied to so-called “card-present” fraud, where the fraudsters are able to create counterfeit copies of stolen credit cards. Continue reading

Hackers Plundered Israeli Defense Firms that Built ‘Iron Dome’ Missile Defense System

July 28, 2014

Three Israeli defense contractors responsible for building the “Iron Dome” missile shield currently protecting Israel from a barrage of rocket attacks were compromised by hackers and robbed of huge quantities of sensitive documents pertaining to the shield technology, KrebsOnSecurity has learned.

The never-before publicized intrusions, which occurred between 2011 and 2012, illustrate the continued challenges that defense contractors and other companies face in deterring organized cyber adversaries and preventing the theft of proprietary information.

According to Columbia, Md.-based threat intelligence firm Cyber Engineering Services Inc. (CyberESI), between Oct. 10, 2011 and August 13, 2012, attackers thought to be operating out of China hacked into the corporate networks of three top Israeli defense technology companies, including Elisra Group, Israel Aerospace Industries, and Rafael Advanced Defense Systems.

By tapping into the secret communications infrastructure set up by the hackers, CyberESI determined that the attackers exfiltrated large amounts of data from the three companies. Most of the information was intellectual property pertaining to Arrow III missiles, Unmanned Aerial Vehicles (UAVs), ballistic rockets, and other technical documents in the same fields of study.

Joseph Drissel, CyberESI’s founder and chief executive, said the nature of the exfiltrated data and the industry that these companies are involved in suggests that the Chinese hackers were looking for information related to Israel’s all-weather air defense system called Iron Dome.

The Israeli government has credited Iron Dome with intercepting approximately one-fifth of the more than 2,000 rockets that Palestinian militants have fired at Israel during the current conflict. The U.S. Congress is currently wrangling over legislation that would send more than $350 million to Israel to further development and deployment of the missile shield technology. If approved, that funding boost would make nearly $1 billion from the United States over five years for Iron Dome production, according to The Washington Post.

Neither Elisra nor Rafael responded to requests for comment about the apparent security breaches. A spokesperson for Israel Aerospace Industries brushed off CyberESI’s finding, calling it “old news.” When pressed to provide links to any media coverage of such a breach, IAI was unable to locate or point to specific stories. The company declined to say whether it had alerted any of its U.S. industry partners about the breach, and it refused to answer any direct questions regarding the incident.

arrow3“At the time, the issue was treated as required by the applicable rules and procedures,” IAI Spokeswoman Eliana Fishler wrote in an email to KrebsOnSecurity. “The information was reported to the appropriate authorities. IAI undertook corrective actions in order to prevent such incidents in the future.”

Drissel said many of the documents that were stolen from the defense contractors are designated with markings indicating that their access and sharing is restricted by International Traffic in Arms Regulations (ITAR) — U.S. State Department controls that regulate the defense industry. For example, Drissel said, among the data that hackers stole from IAI is a 900-page document that provides detailed schematics and specifications for the Arrow 3 missile.

“Most of the technology in the Arrow 3 wasn’t designed by Israel, but by Boeing and other U.S. defense contractors,” Drissel said. “We transferred this technology to them, and they coughed it all up. In the process, they essentially gave up a bunch of stuff that’s probably being used in our systems as well.”

WHAT WAS STOLEN, AND BY WHOM?

According to CyberESI, IAI was initially breached on April 16, 2012 by a series of specially crafted email phishing attacks. Drissel said the attacks bore all of the hallmarks of the “Comment Crew,” a prolific and state-sponsored hacking group associated with the Chinese People’s Liberation Army (PLA) and credited with stealing terabytes of data from defense contractors and U.S. corporations.

The Comment Crew is the same hacking outfit profiled in a February 2013 report by Alexandria, Va. based incident response firm Mandiant, which referred to the group simply by it’s official designation — “P.L.A. Unit 61398.” In May 2014, the U.S. Justice Department charged five prominent military members of the Comment Crew with a raft of criminal hacking and espionage offenses against U.S. firms.

Service Drains Competitors’ Online Ad Budget

July 25, 2014

The longer one lurks in the Internet underground, the more difficult it becomes to ignore the harsh reality that for nearly every legitimate online business there is a cybercrime-oriented anti-business. Case in point: Today’s post looks at a popular service that helps crooked online marketers exhaust the Google AdWords budgets of their competitors.

Youtube ads from “GoodGoogle” pitching his AdWords click fraud service.

AdWords is Google’s paid advertising product, displaying ads on the top or the right side of your screen in search results. Advertisers bid on specific keywords, and those who bid the highest will have their ads show up first when Internet users search for those terms. In turn, advertisers pay Google a small amount each time a user clicks on one of their ads.

One of the more well-known forms of online ad fraud (a.k.a. “click fraud“) involves Google AdSense publishers that automate the clicking of ads appearing on their own Web sites in order to inflate ad revenue. But fraudsters also engage in an opposite scam involving AdWords, in which advertisers try to attack competitors by raising their costs or exhausting their ad budgets early in the day.

Enter “GoodGoogle,” the nickname chosen by one of the more established AdWords fraudsters operating on the Russian-language crime forums.  Using a combination of custom software and hands-on customer service, GoodGoogle promises clients the ability to block the appearance of competitors’ ads.

“Are you tired of the competition in Google AdWords that take your first position and quality traffic,?” reads GoodGoogle’s pitch. “I will help you get rid once and for all competitors in Google Adwords.”

The service, which appears to have been in the offering since at least January 2012, provides customers both a la carte and subscription rates. The prices range from $100 to block between three to ten ad units for 24 hours to $80 for 15 to 30 ad units. For a flat fee of $1,000, small businesses can use GoodGoogle’s software and service to sideline a handful of competitors’s ads indefinitely. Fees are paid up-front and in virtual currencies (WebMoney, e.g.), and the seller offers support and a warranty for his work for the first three weeks. Continue reading

Feds: Hackers Ran Concert Ticket Racket

July 23, 2014

A Russian man detained in Spain is facing extradition to the United States on charges of running an international cyber crime ring that allegedly stole more than $10 million in electronic tickets from e-tickets vendor StubHub.

stubhubVadim Polyakov, 30, was detained while vacationing in Spain. Polyakov is wanted on conspiracy charges to be unsealed today in New York, where investigators with the Manhattan District Attorney’s office and the U.S. Secret Service are expected to announce coordinated raids of at least 20 people in the United States, Canada and the United Kingdom accused of running an elaborate scam to resell stolen e-tickets and launder the profits.

Sources familiar with the matter describe Polyakov, from St. Petersburg, Russia, as the ringleader of the gang, which allegedly used thousands of compromised StubHub user accounts to purchase huge volumes of electronic, downloadable tickets that were fed to a global network of resellers.

Robert Capps, senior director of customer success for RedSeal Networks and formerly head of StubHub’s global trust and safety organization, said the fraud against StubHub — which is owned by eBay — largely was perpetrated with usernames and passwords stolen from legitimate StubHub customers. Capps noted that while banks have long been the target of online account takeovers, many online retailers are unprepared for the wave of fraud that account takeovers can bring.

“In the last year online retailers have come under significant attack by cyber criminals using techniques such as account takeover to commit fraud,” Capps said. “Unfortunately, the transactional risk systems employed by most online retailers are not tuned to detect and defend against malicious use of existing customer accounts.  Retooling these systems to detect account takeovers can take some time, leaving retailers exposed to significant financial losses in the intervening time.”

Polyakov is the latest in a recent series of accused Russian hackers detained while traveling abroad and currently facing extradition to the United States. Dmitry Belorossov, a Russian citizen wanted in connection with a federal investigation into a cyberheist gang that leveraged the Gozi Trojan, also is facing extradition to the United States from Spain. He was arrested in Spain in August 2013 while attempting to board a flight back to Russia. Continue reading

Banks: Card Breach at Goodwill Industries

July 21, 2014

Heads up, bargain shoppers: Financial institutions across the country report that they are tracking what appears to be a series of credit card breaches involving Goodwill locations nationwide. For its part, Goodwill Industries International Inc. says it is working with the U.S. Secret Service on an investigation into these reports.

goodwillHeadquartered in Rockville, Md., Goodwill Industries International, Inc. is a network of 165 independent agencies in the United States and Canada with a presence in 14 other countries. The organizations sell donated clothing and household items, and use the proceeds to fund job training programs, employment placement services and other community-based initiatives.

According to sources in the financial industry, multiple locations of Goodwill Industries stores have been identified as a likely point of compromise for an unknown number of credit and debit cards.

In a statement sent to KrebsOnSecurity, Goodwill Industries said it first learned about a possible incident last Friday, July 18. The organization said it has not yet confirmed a breach, but that it is working with federal authorities on an investigation into the matter.

“Goodwill Industries International was contacted last Friday afternoon by a payment card industry fraud investigative unit and federal authorities informing us that select U.S. store locations may have been the victims of possible theft of payment card numbers,” the company wrote in an email.

Even Script Kids Have a Right to Be Forgotten

July 18, 2014

Indexeus, a new search engine that indexes user account information acquired from more than 100 recent data breaches, has caught many in the hacker underground off-guard. That’s because the breached databases crawled by this search engine are mostly sites frequented by young ne’er-do-wells who are just getting their feet wet in the cybercrime business.

Indexeus[dot]org

Indexeus[dot]org

Indexeus boasts that it has a searchable database of “over 200 million entries available to our customers.” The site allows anyone to query millions of records from some of the larger data breaches of late — including the recent break-ins at Adobe and Yahoo! — listing things like email addresses, usernames, passwords, Internet address, physical addresses, birthdays and other information that may be associated with those accounts.

Who are Indexeus’s target customers? Denizens of hackforums[dot]net, a huge forum that is overrun by novice teenage hackers (a.k.a “script kiddies”) from around the world who are selling and buying a broad variety of services designed to help attack, track or otherwise harass people online.

Few services are as full of irony and schadenfreude as Indexeus. You see, the majority of the 100+ databases crawled by this search engine are either from hacker forums that have been hacked, or from sites dedicated to offering so-called “booter” services — powerful servers that can be rented to launch denial-of-service attacks aimed at knocking Web sites and Web users offline.

The brains behind Indexeus — a gaggle of young men in their mid- to late teens or early 20s — envisioned the service as a way to frighten fellow hackers into paying to have their information removed or “blacklisted” from the search engine. Those who pay “donations” of approximately $1 per record (paid in Bitcoin) can not only get their records expunged, but that price also buys insurance against having their information indexed by the search engine in the event it shows up in future database leaks.

Wireless Live CD Alternative: ZeusGard

July 16, 2014

I’ve long recommended that small business owners and others concerned about malware-driven bank account takeovers consider adopting a “Live CD” solution, which is a free and relatively easy way of temporarily converting your Windows PC into a Linux operating system. The trouble with many of these Live CD solutions is that they require a CD player (something many laptops no longer have) — but more importantly – they don’t play well with wireless access. Today’s post looks at an alternative that addresses both of these issues.

Zeusgard, with wireless adapter, on a Macbook Air.

Zeusgard, with wireless adapter, on a Macbook Air.

As I noted in my 2012 column, “Banking on a Live CD,” the beauty of the “Live CD” approach is that it allows you to safely bank online from any machine — even from a system that is already riddled with malware. That’s because it lets you boot your existing PC into an entirely different (read: non-Windows) operating system. [Not sure why you should consider banking online from a non-Windows PC? Check out this series].

The device I’ll be looking at today is not free, nor is the the tiny dongle that enables its ability to be used on a wireless network. Nor is it an actual CD or anything more than a stripped-down Web browser. But it is one of the safest, most easy-to-use solutions I’ve seen yet.

The device, called ZeusGard, is a small, silver USB flash drive that boots into a usable browser within about 30 seconds after starting the machine. The non-writeable drive boots directly into the browser (on top of Debian Linux), and if your system is hard-wired to your router with an Ethernet connection, you should be good to go.

Nearly all Live CD solution have one glaring weakness: They typically are not usable over a wireless connection. The Live CD solution I most frequently recommend — which is based on a version of Puppy Linux — technically can work with wireless networks, but I found that setting it up is not at all intuitive, especially for people who’ve never used anything but Windows before.

zgbox My review copy of ZeusGard came with a tiny USB wireless Wi-Fi adapter, which makes jumping on a wireless network a complete breeze. When you boot up with both ZeusGard and the adapter plugged in, ZeusGard automatically searches for available wireless networks, and asks you to choose yours from a list of those in range.

Assuming access to your wireless network is secured with WPA/WPA2  (hopefully not the weaker WEP) , click the “properties” box next to your network, and enter your network’s encryption key (if you need to see the key in plain text while you’re typing, tick the box next to “key”). Hit “OK” and then the “Connect” button. Once you’re connected, click the down arrow at the top of the dialog box and select “Exit to Browser Session.” Continue reading

Java Update: Patch It or Pitch It

July 15, 2014

Oracle today released a security update for its Java platform that addresses at least 20 vulnerabilities in the software. Collectively, the bugs fixed in this update earned Oracle’s “critical” rating, meaning they can be exploited over a network without the need for a username and password. In short, if you have Java installed it is time to patch it or pitch it.

javamessThe latest update for Java 7 (the version most users will have installed) brings the program to Java 7 Update 65. Those who’ve chosen to upgrade to the newer, “feature release” version of Java — Java 8 — will find fixes available in Java 8 Update 11.

According to Oracle, at least 8 of the 20 security holes plugged in this release earned a Common Vulnerability Scoring System (CVSS) rating of 9.0 or higher (with 10 being the most severe). Oracle says vulnerabilities with 9.x CVSS score are those which can be easily exploited remotely and without authentication, and which result in the complete compromise of the host operating system.

Beware Keyloggers at Hotel Business Centers

July 14, 2014

The U.S. Secret Service is advising the hospitality industry to inspect computers made available to guests in hotel business centers, warning that crooks have been compromising hotel business center PCs with keystroke-logging malware in a bid to steal personal and financial data from guests.

A DHS/Secret Service advisory dated July 10, 2014.

A DHS/Secret Service advisory dated July 10, 2014.

In a non-public advisory distributed to companies in the hospitality industry on July 10, the Secret Service and the Department of Homeland Security’s National Cybersecurity and Communications Integration Center (NCCIC) warned that a task force in Texas recently arrested suspects who have compromised computers within several major hotel business centers in the Dallas/Fort Worth areas.

“In some cases, the suspects used stolen credit cards to register as guests of the hotels; the actors would then access publicly available computers in the hotel business center, log into their Gmail accounts and execute malicious key logging software,” the advisory reads.

“The keylogger malware captured the keys struck by other hotel guests that used the business center computers, subsequently sending the information via email to the malicious actors’ email accounts,” the warning continues. “The suspects were able to obtain large amounts of information including other guests personally identifiable information (PII), log in credentials to bank, retirement and personal webmail accounts, as well as other sensitive data flowing through the business center’s computers.”

The advisory lists several basic recommendations for hotels to help secure public computers, such as limiting guest accounts to non-administrator accounts that do not have the ability to install or uninstall programs. This is a good all-purpose recommendation, but it won’t foil today’s keyloggers and malware — much of which will happily install on a regular user account just as easily as on an administrative one.

While there are a range of solutions designed to wipe a computer clean of any system changes after the completion of each user’s session (Steady State, Clean Slate, et. al), most such security approaches can be defeated if users also are allowed to insert CDs or USB-based Flash drives (and few hotel business centers would be in much demand without these features on their PCs).
