Who Else Was Hit by the RSA Attackers?

October 24, 2011

The data breach disclosed in March by security firm RSA received worldwide attention because it highlighted the challenges that organizations face in detecting and blocking intrusions from targeted cyber attacks. The subtext of the story was that if this could happen to one of the largest and most integral security firms, what hope was there for organizations that aren’t focused on security?

Security experts have said that RSA wasn’t the only corporation victimized in the attack, and that dozens of other multinational companies were infiltrated using many of the same tools and Internet infrastructure. But so far, no one has been willing to talk publicly about which other companies may have been hit.  Today’s post features a never-before-published list of those victim organizations. The information suggests that more than 760 other organizations had networks that were compromised with some of the same resources used to hit RSA. Almost 20 percent of the current Fortune 100 companies are on this list.

Since the RSA incident was disclosed, lawmakers in the U.S. Congress have taken a renewed interest in so-called “advanced persistent threat” or APT attacks. Some of the industry’s top security experts have been summoned to Capitol Hill to brief lawmakers and staff about the extent of the damage. The information below was shared with congressional staff.

Below is a list of companies whose networks were shown to have been phoning home to some of the same control infrastructure that was used in the attack on RSA. The first victims appear to have begun communicating with the attacker’s control networks as early as November 2010.

A few caveats are in order here. First, many of the network owners listed are Internet service providers, and are likely included because some of their subscribers were hit. Second, it is not clear how many systems in each of these companies or networks were compromised, for how long those intrusions persisted, or whether the attackers successfully stole sensitive information from all of the victims. Finally, some of these organizations (there are several antivirus firms mentioned  below) may be represented because they  intentionally compromised internal systems in an effort to reverse engineer malware used in these attacks.

Among the more interesting names on the list are Abbott Labs, the Alabama Supercomputer Network, Charles Schwabb & Co., Cisco Systems, eBay, the European Space Agency, Facebook, Freddie Mac, Google, the General Services Administration, the Inter-American Development Bank, IBM, Intel Corp., the Internal Revenue Service (IRS), the Massachusetts Institute of Technology, Motorola Inc., Northrop Grumman, Novell, Perot Systems, PriceWaterhouseCoopers LLP, Research in Motion (RIM) Ltd., Seagate Technology, Thomson Financial, Unisys Corp., USAA, Verisign, VMWare, Wachovia Corp., and Wells Fargo & Co.

At the end of the victim list is a pie chart that shows the geographic distribution of the command and control networks used to coordinate the attacks. The chart indicates that the overwhelming majority of the C&Cs are located in or around Beijing, China.

Critical Java Update Fixes 20 Flaws

October 20, 2011
29 Comments

Oracle Corp. released a critical update to plug at least 20 security holes in versions of its ubiquitous Java software. Nearly all of the Java vulnerabilities can be exploited remotely to compromise vulnerable systems with little or no help from users.

If you use Java, take some time to update the program now. According to a report released this month by Microsoft, the most commonly observed exploits in the first half of 2011 were those targeting Java flaws. The report also notes that Java exploits were responsible for between one-third and one-half of all exploits observed in each of the four most recent quarters.

Methods for exploiting one of the flaws fixed by this update were detailed at a recent security conference in Buenos Aires, where researchers demonstrated a method for intercepting encrypted SSL and TLS traffic.

Software Pirate Cracks Cybercriminal Wares

October 17, 2011
25 Comments

Make enough friends in the Internet security community and it becomes clear that many of the folks involved in defending computers and networks against malicious hackers got started in security by engaging in online illegal activity of one sort or another. These gradual mindset shifts are sometimes motivated by ethical, karmic or personal safety reasons, but just as often grey- and black hat hackers gravitate toward the defensive side simply because it is more intellectually challenging.

I first encountered 20-year-old French hacker Steven K. a few months ago while working on a series about the fake antivirus industry. I spent several hours reading accounts of his efforts to frustrate and highlight cybercriminal activity, and took time to follow the many links on his blog, XyliBox, a variant of his hacker alias, “Xylitol.” It turns out that Xylitol, currently unemployed and living with his parents, is something of a major player in the software piracy or “warez” scene, which seeks to crack the copy protection technology built into many computer games and commercial software programs.

As a founding member of redcrew.astalavista.ms (this site may be flagged by some antivirus software as malicious), Xylitol spent several years devising and releasing “cracks,” software patches that allow people to use popular commercial software titles without paying for a license. Cracks are frequently bundled with backdoors, Trojans and other nasties, but Xylitol claims his group never tainted its releases; he says this malicious activity is most often carried out by those who re-purpose and redistribute the pristine patches for their own (commercial and criminal) uses.

But about a year ago, Xylitol began shifting his focus to reverse engineering malware creation kits being marketed and sold on underground cybercrime forums. In October 2010, he began releasing cracked copies of the the bot builder for the SpyEye Trojan, a crimeware kit that sells for several thousand dollars. Each time the SpyEye author released an update, Xylitol would crack it and re-release a free version. This continued for at least a dozen updates in the past year.

The cracked SpyEye releases have been met with a mix of praise and scorn from the security industry; the free releases no doubt frustrated the moneymaking capabilities of the SpyEye author, but they also led to the public distribution of a malware kit that had previously been much harder to come by.

In an instant message chat, Xylitol said he still cracks the occasional commercial software title, just for old time’s sake.

“Sometimes for the old memories, but I’m more into malware cracking now,” he wrote. “It’s more fun.”

Since Nov. 2010, Xylitol and some of his associates have been locked in a daily battle with Russian scareware and ransomware gangs. Scareware programs hijack PCs with incessant and misleading security warnings in a bid to frighten users into paying for the worthless software. Paying customers are given a license key eliminates the annoying security warnings. Ransomware is even more devious: It encrypts the victim’s personal files — pictures, documents, movies and music files — with a custom encryption key. Victims who want their files back usually have little recourse but to pay a fee via text message to receive a code that unlocks the encrypted files.

Xylitol and his pals have been busy over the past year cracking and publishing the license keys needed to free computers snared by scareware and ransomware. For months, these guys have been taking on a Russian ransomeware group called the WinAd gang, releasing the ransomware codes on a daily basis, often just hours after the WinAd gang began pushing out new ransomware variants.

ATM Skimmer Powered by MP3 Player

October 13, 2011
7 Comments

Almost a year ago, I wrote about ATM skimmers made of parts from old MP3 players. Since then, I’ve noticed quite a few more ads for these MP3-powered skimmers in the criminal underground, perhaps because audio skimmers allow fraudsters to sell lucrative service contracts along with their theft devices.

Using audio to capture credit and debit card data is not a new technique, but it is becoming vogue: Square, an increasingly popular credit card reader built for the iPhone, works by plugging into the headphone jack on the iPhone and converting credit card data stored on the card into audio files.

An audio skimmer for a Diebold ATM.

The device pictured here is a card skimmer designed to fit over the card acceptance slot on a Diebold Opteva 760, one of the most common ATMs around. The green circuit board on the left was taken from an MP3 player (no idea which make or model). When a card is slid past the magnetic reader (the small black rectangle at the end of the black and red wires near the center of the picture), the MP3 player “hears” the data stored on the card’s magnetic stripe, and records it as an audio file to a tiny embedded flash memory device.

Shady Reshipping Centers Exposed, Part I

October 12, 2011
50 Comments

Last week, authorities in New York indicted more than 100 people suspected of being part of a crime ring that used forged credit cards to buy and resell an estimated $13 million worth of Apple products and other electronics overseas. In this post, I offer readers a behind-the-scenes look at a somewhat smaller but similar organized crime operation that uses stolen credit card numbers to purchase and launder high-end electronics.

One of the simplest ways to extract cash from stolen credit card accounts is to buy pricey consumer goods online and resell them on the black market. Most online retailers grew wise to these scams years ago and stopped shipping to regions of the world most frequently associated with credit card fraud, including Eastern Europe, North Africa, and Russia. But these restrictions have created a burgeoning underground market for reshipping scams, which rely on willing or unwitting residents in the United States and Europe to receive and relay high-dollar stolen goods to crooks living in the embargoed areas.

There are dozens of businesses in the criminal underground engaged in merchandise laundering, known as “Drops for stuff” on cybercrime forums. The “drops” are people who have responded to work-at-home package reshipping jobs advertised on craigslist.com and job search sites. Most reshipping scams promise employees a monthly salary and cash bonuses. But the crooks almost always sever communications with drops just before the first payday, usually about a month after the drop ships their first package.

Dropforrent.net account for manager Dick Martin.

A typical drop will receive and reship between two and four packages per day.  The packages arrive with prepaid shipping labels that are paid for with stolen credit card numbers, or with hijacked online accounts at FedEx and the US Postal Service. Drops are responsible for inspecting and verifying the contents of shipments, attaching the correct shipping label to each package, and sending them off via the appropriate shipping company.

One drops operation, dropforrent.net, allows “clients” to “rent” drops who have signed up for reshipping jobs. “Managers,” those who facilitate drop recruitment scams, can earn money by purchasing merchandise that the reshipping operation can quickly resell. Most reshipping operations seek consumer electronics that can be easily sold for cash, including laptop computers, cameras, smart phones and parts for sports cars. Dropforrent.com pays managers and clients 30 percent of the value of laptops from ACER, HP, Toshiba, Dell, Compaq and Samsung, for example, and more than 40 percent of the retail price for Apple, Sony, VAIO, Canon and Nikon products.

The phony storefront for a drops recruitment scheme.

Drops also can be used to reship virtually anything else that the client or manager would like to use or consume themselves, such as clothes, jewelry, and candy. For this service, clients and managers pay a flat rate of 50 percent of the value of the goods to have the items reshipped abroad.

The dropforrent.com managers recruit new hires by posing as legitimate businesses. One manager who uses the name Dick Martin operates a dummy business called applestore-direct.com, and actively recruits drops via ads on craigslist.com. Recruited drops are given a login to applestore-direct.com where they receive daily updates about pending shipments. Drops also are required to use this Web-based interface to notify their managers of received and reshipped items.

Kent Tribbett, a 24-year-old from West Berlin, New Jersey, has been reshipping for applestore-direct.com for almost three weeks. He was hired by Martin via an ad on craigslist.com and was given an account at applestore-direct, where he was instructed to log in daily to receive and transmit information about packages arriving at his home. A screen shot of his user account is below.

According to Dick Martin’s account at dropforrent, at least 10 clients were using Tribbett as a drop. Those same records show that Tribbett was one of 60 different drops recruited by Martin in the past 10 months.

I spoke with Tribbett briefly by phone; he denied receiving or reshipping packages for applestore-direct.com, and then hung up. But the numerous USPS tracking numbers and Express Mail bills attached to the past shipments in his account at the site suggest otherwise.

Critical Security Updates from Microsoft, Apple

October 11, 2011
0 Comments

Microsoft and Apple today released security updates to fix a slew of critical security problems in their software. Microsoft’s patch batch fixes at least 23 vulnerabilities in Windows and other Microsoft products. Apple’s update addresses more than 75 security flaws in the Windows versions of iTunes.

Nine of the 23 flaws Microsoft fixed with patches today are rated “critical,” meaning attackers could exploit them to break into vulnerable systems with little or no help from users. Eight of the nine critical bugs are in Internet Explorer. The remaining critical flaw is corrected in an update for the .NET Framework. Three of the vulnerabilities fixed with these updates were disclosed publicly prior to today, including a flaw in Windows Media Center that Microsoft believes crooks are likely to soon figure out how to reliably exploit.

The iTunes update brings the music player software to version 10.5, and is available for Microsoft systems running Windows 7, Vista, XP SP2 and later. Two new features of iTunes deserve mentioning: Apple says iPhone and iPad users who upgrade to iOS 5 when it is released later this week will be able to sync with iTunes wirelessly. More importantly from an update perspective, Apple has at long last untethered iTunes from QuickTime.

Identity Theft More Profitable Than Car Theft

October 10, 2011
20 Comments

Buying a car or making any other expensive purchase can be a hassle. And when it’s necessary to finance a purchase, there’s one more hurdle. If you want merchant financing, you’ll often be required to fill out a credit application or, at the least, to provide information like a credit card or your Social Security number.

Recent hacker break-ins at a half-dozen car dealerships nationwide are a reminder of just how easily one’s personal and financial information can be jeopardized by poor security at any of of tens of thousands of organizations that have access to that data.

Earlier this month, Farmington Hills, Mich. based RouteOne LLC sent a letter to more than 20,000 dealerships around the country, warning of probable malware infections at six dealerships that use its service. Formed in 2002, RouteOne is a joint venture by GMAC (now called Ally Financial), Ford Motor Credit, Toyota Financial Services, and DaimlerChrysler Financial Services. Dealerships use RouteOne’s credit application software and Web portal to run credit checks and process financing for car buyers. The service also allows authorized users to pull credit reports from the three major credit reporting bureaus.

In September 2011, RouteOne issued a “security bulletin,” to its affiliates, stating in part:

A letter from RouteOne to partner dealerships.

“Over the recent past, RouteOne has received information regarding a small number of dealerships (6) that have experienced compromises in their system security environments (including misappropriation and misuse of their RouteOne log on credentials likely as a result of their dealership computers being infected with spyware). RouteOne is in contact and working with affected dealerships in an attempt to help them address their security issues.”

The bulletin states further than RouteOne “takes these matters very seriously and therefore has been in contact with the FBI and the U.S. Secret Service. Ryan Holmes, the Secret Service agent assigned to the investigation of the attacks on RouteOne’s customers, said he could not release any information on an active investigation.

Mass data collection, and the resulting potential for cybertheft, is a relatively recent problem. Ten years ago, data aggregation points like RouteOne didn’t exist. RouteOne was created to speed credit and financing processes at dealerships, which previously had to navigate to and authenticate at multiple finance vendors, lenders and credit bureaus. Today, dealerships can access all this information with a username and password at RouteOne.net, or via a RouteOne iPhone app.

Dan Doman, vice president and general counsel for RouteOne, said the company became aware of the unauthorized activity after it was notified by the affected dealers.

“It’s important to note that RouteOne has not been breached in this instance, or ever in the past,” Doman said. “What we do when we learn of these matters is we try to get it out to our dealers as quickly as possible so they can take appropriate steps to fix it.”

ID theft services for sale.

Technically, RouteOne is correct. It did not have a data breach: Some of the customers who use their service did. But that distinction is irrelevant to thieves who prize such access, and to consumers who find their identities hijacked and themselves saddled with unexpected debts from fraudulent new lines of credit opened in their names. The criminal underground is full of services that allow miscreants to look up Social Security numbers, dates of birth, maiden names, and other sensitive information. It’s not clear where that data comes from, but the most likely sources are compromised accounts at businesses and organizations that have easy and frequent access to consumer data.

This blog post isn’t intended to single out RouteOne; that is just a recent example of a vast problem for individuals who must share personal data. The same kind of data aggregation exists in many other businesses and tens of thousands of organizations that routinely access sensitive consumer data, including medical, dental and real estate services. Thieves can access a gold mine of consumer data just by compromising PCs at any of these places. Continue reading →

How Much is That Phished PayPal Account?

October 5, 2011
65 Comments

Compromised PayPal accounts are a valuable commodity in the criminal underground, and crooks frequently trade them in shadowy online forums. But it wasn’t until recently that I finally encountered a proper Web site dedicated to selling hacked PayPal accounts.

Compromised PayPal accounts for sale at iProfit.su

Many of the PayPal accounts for sale at iProfit.su have a zero balance, but according to the proprietor of this shop these are all “verified.” PayPal “verifies” an account when a customer agrees to attach a bank account to it; PayPal then sends a micropayment the bank account, and asks the user the value of that mini deposit. A bonus feature: all the hacked PayPal profiles currently for sale at iProfit.su are advertised as having a credit card attached to them, which is another way PayPal accounts can be verified.

The creator of iProfit.su also advertises private, bulk sales of unverified PayPal accounts; currently he is selling these at $50 per 100 accounts – a bargain at only 50 cents apiece.

Accounts are sold with or without email access (indicated by the “email” heading in the screenshot above): Accounts that come with email access include the username and password of the victim’s email account that they used to register at PayPal, the site’s proprietor told me via instant message. The creator of iProfit.su told me the accounts for sale were stolen via phishing attacks, but the fact that accounts are being sold along with email access suggests that at least some of the accounts are being hijacked by password-stealing computer Trojans on account holders’ PCs.

ZeuS Trojan Gang Faces Justice

Authorities in the United Kingdom have convicted the 13th and final defendant from a group arrested last year and accused of running an international cybercrime syndicate that laundered millions of dollars stolen from consumers and businesses with the help of the help of the ZeuS banking Trojan. The news comes days after U.S. authorities announced the guilty plea of the 27th and final individual arrested last year in New York in a related international money-laundering scheme.

Yevhen Kulibaba

Yevhen Kulibaba

According to the Metropolitan Police, the U.K. courts have convicted 13 members of the gang, including four who were profiled last year by KrebsOnSecurity shortly after their initial arrest and charging. The gang is thought to have used the ZeuS Trojan to steal nearly £3 million (USD $4.6M) from banks in the U.K.. They are believed to be responsible for aiding in the theft of at least USD $3 million from U.S. banks and businesses in the past two years.

Karina Kostromina

Among those convicted were the husband-and-wife ringleaders of the gang, 33-year-old Ukrainian property developer Yevhen Kulibaba, and his wife, Karina Kostromina, 34. According to British prosecutors, the two lived a “jet set” lifestyle and spent money on holidays, cars and property. Kostromina was cleared of conspiracy charges but convicted of money laundering, and sentenced this week to two years in prison. Kulibaba is awaiting sentencing on charges of conspiracy to defraud.

Monster Spam Campaigns Lead to Cyberheists

October 3, 2011
27 Comments

Phishers and cyber thieves have been casting an unusually wide net lately, blasting out huge volumes of fraudulent email designed to spread password-stealing banking Trojans. Judging from the number of victims who reported costly cyber heists in the past two weeks, many small to medium sized organizations took the bait.

These fake NACHA lures were mailed the week of Sept. 19, even though the sent date on the message says Aug. 3. Source: Commtouch.

Security firm Symantec says it detected an unprecedented jump in spam blasts containing “polymorphic malware,” — malicious software that constantly changes its appearance to evade security software. One of the most tried-and-true lures used in these attacks is an email crafted to look like it was sent by NACHA, a not-for-profit group that develops operating rules for organizations that handle electronic payments, from payroll direct deposits to online bill pay services.

Using NACHA’s name as bait is doubly insulting because victims soon find new employees — money mules — added to their payroll. After adding the mules, the thieves use the victim’s online banking credentials to push through an unauthorized batch of payroll payments to the mules, who are instructed to pull the money out in cash and wire the funds (minus a commission) overseas.

On Sept. 13, computer crooks stole approximately $120,000 from Oncology Services of North Alabama, a component of the Center for Cancer Care, a large medical health organization in Alabama. John Ziak, director of information technology at the center, said he suspects the organization’s accounting firm was the apparent source of the compromise. That means other clients may also have been victimized. He declined to name the accounting firm.
