SpyEye Makers Get 24 Years in Prison

April 20, 2016

Two hackers convicted of making and selling the infamous SpyEye botnet creation kit were sentenced in Georgia today to a combined 24 years in prison for helping to infect hundreds of thousands of computers with malware and stealing millions from unsuspecting victims.

The Justice Department alleges that 24-year-old Aleksander Panin was responsible for SpyEye. Image courtesy: RT.

Atlanta Judge Amy Totenberg handed down a sentence of nine years, six months for Aleksandr Andreevich Panin, a 27-year-old Russian national also known by the hacker aliases “Gribodemon” and “Harderman.”

Convicted of conspiracy to commit wire and bank fraud, Panin was the core developer and distributor of SpyEye, a botnet toolkit that made it easy for relatively unsophisticated cyber thieves to steal millions of dollars from victims.

Sentenced to 15 years in jail was Panin’s business partner —  27-year-old Hamza “Bx1” Bendelladj, an Algerian national who pleaded guilty in June 2015 to helping Panin develop and market the SpyEye kit. Bendelladj also admitting to running his own SpyEye botnet of hacked Windows computers, a crime machine that he used to harvest and steal 200,000 credit card numbers. By the government’s math (an assumed $500 loss per card) Bx1 was potentially responsible for $100 million in losses.

“It is difficult to over state the significance of this case, not only in terms of bringing two prolific computer hackers to justice, but also in disrupting and preventing immeasurable financial losses to individuals and the financial industry around the world,” said John Horn, U.S. Attorney for the Northern District of Georgia.

THE HAPPY HACKER

Bendelladj was arrested in Bangkok in January 2013 while in transit from Malaysia to Egypt. He quickly became known as the “happy hacker” after his arrest, in which he could be seen smiling broadly while in handcuffs and being paraded before the local news media.

In its case against the pair of hackers, the government presented chat logs between Bendelladj and Panin and other hackers. The government says the chat logs reveal that although Bendelladj worked with Panin to fuel the rise of SpyEye by vouching for him on cybercrime forums such as “Darkode,” the two had an antagonistic relationship.

Their business partnership imploded after Bx1 announced that he was publicly releasing the source code for SpyEye.

“Indeed, after Bendelladj ‘cracked’ SpyEye and made it available to others without having to purchase it from Panin, the two had a falling out,” reads the government’s sentencing memo (PDF) to the judge in the case.

The government says that while Bendelladj maintained he was little more than a malware analyzer working for a security company, his own chat logs put the lie to that claim, noting in November 2012 Bx1 bluntly said: “if they pay me the whole money of the world . . . I wont work for security.”

Bx1 had a penchant for marketing to other thieves. He shrewdly cast SpyEye as a lower-cost, more powerful alternative to the Zeus botnet creation kit, plastering cybercrime forums with animated ads pimping SpyEye as the “Zeuskiller” (in part because SpyEye was designed to remove Zeus from host computers before infecting them).

Giant Food Sees Giant Card Fraud Spike

April 20, 2016

Citing a recent and large increase in credit card fraud, Washington, DC-area grocer Giant Food says it will no longer allow customers to use credit cards when purchasing gift cards and reloadable or prepaid debit cards.

A new warning sign at Giant Food checkout counters. Giant says the warning was prompted by a spike in credit card fraud.

A new warning sign at Giant Food checkout counters. Giant says the warning was prompted by a spike in credit card fraud.

I had no idea this was a new thing at Landover, Md.-based Giant, which operates 169 supermarkets in the Washington, D.C. metro area.  That is, until I encountered a couple of large new “attention” stickers in the checkout line at a local Giant in Virginia recently. Next to the credit card terminal were big decals with the warning:

“Attention Gift Card Customers: Effective immediately, all purchases of Visa, MasterCard, American Express Gift Cards and all General Purpose Reloadable or Prepaid Cards may only be made with Cash or Bank Pin-based Debit.”

Asked for comment about the change, Giant Food released a brief statement about the policy change that went into effect in March 2016, but otherwise didn’t respond to requests for more details.

“Giant has recently made a change in procedures for purchasing gift cards because of a large increase of fraudulent gift card purchasing,” the company said. “Giant will now accept only a Bank PIN-based debit card or cash for all VISA, MasterCard, and American Express gift cards, as well as re-loadable and prepaid gift cards. This change has been made in order to mitigate potential fraud risk.”

It’s not clear why Giant is only just now taking this basic anti-fraud step. Card thieves love to pick on grocery and convenience stores. Street gangs involved in card fraud (and they’re all involved in card fraud now) often extract money from grocery, dollar and convenience stores using “runners” — low-level members who are assigned the occasionally risky business of physically “cashing out” counterfeit credit and debit cards.

One of the easiest ways thieves can cash out? Walk into a grocery or retail store and buy prepaid gift cards using stolen credit cards. Such transactions — if successful — effectively launder money by converting the stolen item (counterfeit/stolen card) into a good that is equivalent to cash or can be easily resold for cash (gift cards).

I witnessed this exact crime firsthand at a Giant in Maryland last year. As I noted in a Dec. 2015 post about gift card fraud, the crooks caught in the process of these cashout schemes usually are found with dozens of counterfeit credit cards on their person or in their vehicle. From that post: Continue reading

US-CERT to Windows Users: Dump Apple Quicktime

April 18, 2016

Microsoft Windows users who still have Apple Quicktime installed should ditch the program now that Apple has stopped shipping security updates for it, warns the Department of Homeland Security‘s U.S. Computer Emergency Readiness Team (US-CERT). The advice came just as researchers are reporting two new critical security holes in Quicktime that likely won’t be patched.

quicktimeUS-CERT cited an April 14 blog post by Christopher Budd at Trend Micro, which runs a program called Zero Day Initiative (ZDI) that buys security vulnerabilities and helps researchers coordinate fixing the bugs with software vendors. Budd urged Windows users to junk Quicktime, citing two new, unpatched vulnerabilities that ZDI detailed which could be used to remotely compromise Windows computers.

“According to Trend Micro, Apple will no longer be providing security updates for QuickTime for Windows, leaving this software vulnerable to exploitation,” US-CERT wrote. The advisory continued:

“Computers running QuickTime for Windows will continue to work after support ends. However, using unsupported software may increase the risks from viruses and other security threats. Potential negative consequences include loss of confidentiality, integrity, or availability of data, as well as damage to system resources or business assets. The only mitigation available is to uninstall QuickTime for Windows. Users can find instructions for uninstalling QuickTime for Windows on the Apple Uninstall QuickTime page.”

While the recommendations from US-CERT and others apparently came as a surprise to many, Apple has been distancing itself from QuickTime on Windows for some time now. In 2013, the Cupertino, Calif. tech giant deprecated all developer APIs for Quicktime on Windows.

Apple shipped an update to Quicktime in January 2016 that removed the Quicktime browser plugin on Windows systems, meaning the threat from browser-based attacks on Quicktime flaws was largely mitigated over the past few months for Windows users who have been keeping up to date with the latest version. Nevertheless, if you have Quicktime on a Windows box — do yourself a favor and get rid of it.

Update, Apr. 21, 10:00 a.m. ET: Apple has finally posted a support document online that explains QuickTime 7 for Windows is no longer supported by Apple. See the full advisory here.

‘Blackhole’ Exploit Kit Author Gets 7 Years

April 14, 2016

A Moscow court this week convicted and sentenced seven hackers for breaking into countless online bank accounts — including “Paunch,” the nickname used by the author of the infamous “Blackhole” exploit kit.  Once an extremely popular crimeware-as-a-service offering, Blackhole was for several years responsible for a large percentage of malware infections and stolen banking credentials, and likely contributed to tens of millions of dollars stolen from small to mid-sized businesses over several years.

Paunch, the accused creator of the Blackhole Exploit Kit, stands in front of his Porche Cayenne.

Fedotov, the convicted creator of the Blackhole Exploit Kit, stands in front of his Porche Cayenne in an undated photo.

According to Russia’s ITAR-TASS news network, Dmitry “Paunch” Fedotov was sentenced on April 12 to seven years in a Russian penal colony. In October 2013, the then 27-year-old Fedotov was arrested along with an entire team of other cybercriminals who worked to sell, develop and profit from Blackhole.

According to Russian security firm Group-IB, Paunch had more than 1,000 customers and was earning $50,000 per month from his illegal activity. The image at right shows Paunch standing in front of his personal car, a Porsche Cayenne.

First spotted in 2010, BlackHole is commercial crimeware designed to be stitched into hacked or malicious sites and exploit a variety of Web-browser vulnerabilities for the purposes of installing malware of the customer’s choosing.

The price of renting the kit ran from $500 to $700 each month. For an extra $50 a month, Paunch also rented customers “crypting” services; cryptors are designed to obfuscate malicious software so that it remains undetectable by antivirus software.

Paunch worked with several other cybercriminals to purchase new exploits and security vulnerabilities that could be rolled into Blackhole and help increase the success of the software. He eventually sought to buy the exploits from other cybercrooks directly to fund a pricier ($10,000/month) and more exclusive exploit pack called “Cool Exploit Kit.”

As documented on this blog in January 2013 (see Crimeware Author Funds Exploit Buying Spree), Paunch contracted with a third-party exploit broker who announced that he had a $100,000 budget for buying new, previously undocumented “zero-day” vulnerabilities.

Not long after that story, the individual with whom Paunch worked to purchase those exclusive exploits — a miscreant who uses the nickname “J.P. Morgan” — posted a message to the Darkode[dot]com crime forum, stating that he was doubling his exploit-buying budget to $200,000. Continue reading

‘Badlock’ Bug Tops Microsoft Patch Batch

April 13, 2016

Microsoft released fixes on Tuesday to plug critical security holes in Windows and other software. The company issued 13 patches to tackle dozens of vulnerabilities, including a much-hyped “Badlock” file-sharing bug that appears ripe for exploitation. Also, Adobe updated its Flash Player release to address at least two-dozen flaws — in addition to the zero-day vulnerability Adobe patched last week.

The Windows patch that seems to be getting the most attention this month remedies seven vulnerabilities in Samba, a service used to manage file and print services across networks and multiple operating systems. This may sound innocuous enough, but attackers who gain access to private or corporate network could use these flaws to intercept traffic, view or modify user passwords, or shut down critical services.

According to badlock.org, a Web site set up to disseminate information about the widespread nature of the threat that this vulnerability poses, we are likely to see active exploitation of the Samba vulnerabilities soon.

Two of the Microsoft patches address flaws that were disclosed prior to Patch Tuesday. One of them is included in a bundle of fixes for Internet Explorer. A critical update for the Microsoft Graphics Component targets four vulnerabilities, two of which have been detected already in exploits in the wild, according to Chris Goettl at security vendor Shavlik.

Just a reminder: If you use Windows and haven’t yet taken advantage of the Enhanced Mitigation Experience Toolkit, a.k.a. “EMET,” you should definitely consider it. I describe the basic features and benefits of running EMET in this blog post from 2014 (yes, it’s time to revisit EMET in a future post), but the gist of it is that EMET helps block or blunt exploits against known and unknown Windows vulnerabilities and flaws in third-party applications that run on top of Windows. The latest version, v. 5.5, is available hereContinue reading

New Threat Can Auto-Brick Apple Devices

April 12, 2016

If you use an Apple iPhone, iPad or other iDevice, now would be an excellent time to ensure that the machine is running the latest version of Apple’s mobile operating system — version 9.3.1. Failing to do so could expose your devices to automated threats capable of rendering them unresponsive and perhaps forever useless.

Zach Straley demonstrating the fatal Jan. 1, 1970 bug. Don't try this at home!

Zach Straley demonstrating the fatal Jan. 1, 1970 bug. Don’t try this at home!

On Feb. 11, 2016, researcher Zach Straley posted a Youtube video exposing his startling and bizarrely simple discovery: Manually setting the date of your iPhone or iPad all the back to January. 1, 1970 will permanently brick the device (don’t try this at home, or against frenemies!).

Now that Apple has patched the flaw that Straley exploited with his fingers, researchers say they’ve proven how easy it would be to automate the attack over a network, so that potential victims would need only to wander within range of a hostile wireless network to have their pricey Apple devices turned into useless bricks.

Not long after Straley’s video began pulling in millions of views, security researchers Patrick Kelley and Matt Harrigan wondered: Could they automate the exploitation of this oddly severe and destructive date bug? The researchers discovered that indeed they could, armed with only $120 of electronics (not counting the cost of the bricked iDevices), a basic understanding of networking, and a familiarity with the way Apple devices connect to wireless networks.

Apple products like the iPad (and virtually all mass-market wireless devices) are designed to automatically connect to wireless networks they have seen before. They do this with a relatively weak level of authentication: If you connect to a network named “Hotspot” once, going forward your device may automatically connect to any open network that also happens to be called “Hotspot.”

For example, to use Starbuck’s free Wi-Fi service, you’ll have to connect to a network called “attwifi”. But once you’ve done that, you won’t ever have to manually connect to a network called “attwifi” ever again. The next time you visit a Starbucks, just pull out your iPad and the device automagically connects.

From an attacker’s perspective, this is a golden opportunity. Why? He only needs to advertise a fake open network called “attwifi” at a spot where large numbers of computer users are known to congregate. Using specialized hardware to amplify his Wi-Fi signal, he can force many users to connect to his (evil) “attwifi” hotspot. From there, he can attempt to inspect, modify or redirect any network traffic for any iPads or other devices that unwittingly connect to his evil network.

TIME TO DIE

And this is exactly what Kelley and Harrigan say they have done in real-life tests. They realized that iPads and other iDevices constantly check various “network time protocol” (NTP) servers around the globe to sync their internal date and time clocks.

The researchers said they discovered they could build a hostile Wi-Fi network that would force Apple devices to download time and date updates from their own (evil) NTP time server: And to set their internal clocks to one infernal date and time in particular: January 1, 1970.

Harrigan and Kelley named their destructive Wi-Fi network "Phonebreaker."

Harrigan and Kelley named their destructive Wi-Fi test network “Phonebreaker.”

The result? The iPads that were brought within range of the test (evil) network rebooted, and began to slowly self-destruct. It’s not clear why they do this, but here’s one possible explanation: Most applications on an iPad are configured to use security certificates that encrypt data transmitted to and from the user’s device. Those encryption certificates stop working correctly if the system time and date on the user’s mobile is set to a year that predates the certificate’s issuance.

Harrigan and Kelley said this apparently creates havoc with most of the applications built into the iPad and iPhone, and that the ensuing bedlam as applications on the device compete for resources quickly overwhelms the iPad’s computer processing power. So much so that within minutes, they found their test iPad had reached 130 degrees Fahrenheit (54 Celsius), as the date and clock settings on the affected devices inexplicably and eerily began counting backwards.

FBI: $2.3 Billion Lost to CEO Email Scams

April 7, 2016

The U.S. Federal Bureau of Investigation (FBI) this week warned about a “dramatic” increase in so-called “CEO fraud,” e-mail scams in which the attacker spoofs a message from the boss and tricks someone at the organization into wiring funds to the fraudsters. The FBI estimates these scams have cost organizations more than $2.3 billion in losses over the past three years.

In an alert posted to its site, the FBI said that since January 2015, the agency has seen a 270 percent increase in identified victims and exposed losses from CEO scams. The alert noted that law enforcement globally has received complaints from victims in every U.S. state, and in at least 79 countries.

A typical CEO fraud attack. Image: Phishme

CEO fraud usually begins with the thieves either phishing an executive and gaining access to that individual’s inbox, or emailing employees from a look-alike domain name that is one or two letters off from the target company’s true domain name. For example, if the target company’s domain was “example.com” the thieves might register “examp1e.com” (substituting the letter “L” for the numeral 1) or “example.co,” and send messages from that domain.

Unlike traditional phishing scams, spoofed emails used in CEO fraud schemes rarely set off spam traps because these are targeted phishing scams that are not mass e-mailed. Also, the crooks behind them take the time to understand the target organization’s relationships, activities, interests and travel and/or purchasing plans.

They do this by scraping employee email addresses and other information from the target’s Web site to help make the missives more convincing. In the case where executives or employees have their inboxes compromised by the thieves, the crooks will scour the victim’s email correspondence for certain words that might reveal whether the company routinely deals with wire transfers — searching for messages with key words like “invoice,” “deposit” and “president.”

On the surface, business email compromise scams may seem unsophisticated relative to moneymaking schemes that involve complex malicious software, such as Dyre and ZeuS. But in many ways, CEO fraud is more versatile and adept at sidestepping basic security strategies used by banks and their customers to minimize risks associated with account takeovers. In traditional phishing scams, the attackers interact with the victim’s bank directly, but in the CEO scam the crooks trick the victim into doing that for them.

The FBI estimates that organizations victimized by CEO fraud attacks lose on average between $25,000 and $75,000. But some CEO fraud incidents over the past year have cost victim companies millions — if not tens of millions — of dollars.  Continue reading

After Tax Fraud Spike, Payroll Firm Greenshades Ditches SSN/DOB Logins

April 6, 2016

Online payroll management firm Greenshades.com is an object lesson in how not to do authentication. Until very recently, the company allowed corporate payroll administrators to access employee payroll data online using nothing more than an employee’s date of birth and Social Security number. That is, until criminals discovered this and began mass-filing fraudulent tax refund requests with the IRS on large swaths of employees at firms that use the company’s services.

A notice on the Greenshades Web site.

A notice on the Greenshades Web site.

Jacksonville, Fla.-based Greenshades posted an alert on its homepage stating that the company “has seen an abnormal increase in identity thieves using personal information to fraudulently log into the company’s system to access personal tax information.”

Many online services blame these sorts of attacks on customers re-using the same password at multiple sites, but Greenshades set customers up for this by allowing access to payroll records just by supplying the employee’s Social Security number and date of birth.

As this author has sought repeatedly to demonstrate, SSN/DOB information is extremely easy and cheap to obtain via multiple criminal-run Web sites: SSN/DOB data is reliably available for purchase from underground online crime shops for less than $4 per person (payable in Bitcoin only).

The spike in tax fraud against employees of companies that use Greenshades came to light earlier this month in various media stories. A number of employees at public high schools in Chicago discovered that crooks beat them to the punch on filing tax returns. An investigation into that incident suggested security weaknesses at Greenshades were to blame.

The Milwaukee Journal Sentinel wrote last month about tax fraud perpetrated against local county workers, fraud that also was linked to compromised Greenshades accounts. In Nebraska, the Lower Platte North Natural Resources District and Fremont Health hospital had a number of employees with tax fraud linked to compromised Greenshades accounts, according to a report in the Fremont Tribune.

Greenshades co-CEO Matthew Kane said the company allowed payroll administrators to access W2 information with nothing more than SSN and DOB for one simple reason: Many customers demanded it.

“There’s a valid reason to have what I call weak login credentials,” Kane told KrebsOnSecurity. “Some of our clients clamor for weaker login credentials, such as companies that have a large staff of temporary workers.”

Kane said customers have a “wide range of options” to select from in choosing how they will authenticate to Greenshades.com, but that the most secure option currently offered is a simple username and password.

When asked whether the company offers any sort of two-step or two-factor authentication, Kane argued that corporate email addresses assigned to company employees serve as a kind of second factor. Continue reading

Sources: Trump Hotels Breached Again

April 4, 2016

Banking industry sources tell KrebsOnSecurity that the Trump Hotel Collection — a string of luxury properties tied to business magnate and Republican presidential candidate Donald Trump — appears to be dealing with another breach of its credit card systems. If confirmed, this would be the second such breach at the Trump properties in less than a year.

A representative from Trump Hotels said the organization was investigating the claims.

“We are in the midst of a thorough investigation on this matter,” the company said in a written statement. “We are committed to safeguarding all guests’ personal information and will continue to do so vigilantly.”

KrebsOnSecurity reached out to the Trump organization after hearing from three sources in the financial sector who said they’ve noticed a pattern of fraud on customer credit cards which suggests that hackers have breached credit card systems at some — if not all — of the Trump Hotel Collection properties.

On July 1, 2015, this publication was the first to report that banks suspected a breach at Trump properties. After that story ran, Trump Hotel Collection acknowledged being alerted about suspicious activity tied to accounts that were recently used at its hotels. But it didn’t officially confirm that its payment systems had been infected with card-stealing malware until October 2015.

The Trump Hotel Collection includes more than a dozen properties globally. Sources said they noticed a pattern of fraud on cards that were all used at multiple Trump hotel locations in the past two to three months, including at Trump International Hotel New York, Trump Hotel Waikiki in Honolulu, and the Trump International Hotel & Tower in Toronto.
