Fraudsters Tap Kohl’s Cash for Cold Cash

Scam artists have been using hacked accounts from retailer Kohls.com to order high-priced, bulky merchandise that is then shipped to the victim’s home. While the crooks don’t get the stolen merchandise, the unauthorized purchases rack up valuable credits called “Kohl’s cash” that the thieves quickly redeem at Kohl’s locations for items that can be resold for cash or returned for gift cards.

kohlscashKrebsOnSecurity reader Suzanne Perry, a self-professed “shopaholic” from Gilbert, Penn., said she recently received an email from Kohls.com stating that the email address on her account had been changed. Recognizing this as a common indicator of a compromised account, Perry said she immediately went to Kohls.com — which confirmed her fears that her password had been changed.

On a whim, Perry said she attempted to log in with the “updated” email address (the one the thief used) along with her existing password. Happily, the thieves had been too lazy to change the password.

“Once I was logged in, I checked my order history to determine if any fraudulent orders were placed in the 20 minutes since I received the notification,” she said. “I wasn’t that surprised to see two online orders, totaling almost $700 each, but I was very surprised to see they were being shipped to my house and not some address I never heard of.”

Perry said she then contacted Kohl’s and gave them the two order numbers and the fraudulent email address.

“I explained what happened, and they were very helpful in canceling the orders, updating my email address, and resetting my password,” she said. “I told them I couldn’t understand why someone would hack into my account just to have a bunch of stuff shipped to my own address. I was trying to figure out what the criminal would possibly have to gain from the effort, but the service representative informed me that is actually a very common occurrence for them.”

Turns out, the criminal wasn’t after the merchandise at all. Rather, the purpose of changing her email address was to drain the account’s stored Kohl’s cash, a form of rebate that Kohl’s offers customers — currently $10 for every $50 spent at the store. The two fraudulent orders yielded $220 in Kohls cash total, which is emailed once the order is confirmed (hence the need to change the victim’s email address).

“Since the orders were being shipped to me, even though they were  above the threshold for what my typical online spending behavior is, no red flags were raised on their end,” Perry said.

More interestingly, virtually all of the merchandise the thieves ordered to build up the account’s Kohl’s cash balance were bulky items: Three baby cribs, a stroller system and car seat, and a baby bath tub, among other items. Perry said Kohl’s told her that the thieves do this because they know bulky items usually take longer to return, and since Kohl’s revokes Kohl’s cash credits earned on items that are later returned, the thieves can spend the stolen Kohl’s credits as long as the owner of the hijacked account doesn’t return the fraudulently ordered items.

Firm Sues Cyber Insurer Over $480K Loss

A Texas manufacturing firm is suing its cyber insurance provider for refusing to cover a $480,000 loss following an email scam that impersonated the firm’s chief executive.

athookAt issue is a cyber insurance policy issued to Houston-based Ameriforge Group Inc. (doing business as “AFGlobal Corp.“) by Federal Insurance Co., a division of insurance giant Chubb Group. AFGlobal maintains that the policy it held provided coverage for both computer fraud and funds transfer fraud, but that the insurer nevertheless denied a claim filed in May 2014 after scammers impersonating AFGlobal’s CEO convinced the company’s accountant to wire $480,000 to a bank in China.

According to documents filed with the U.S. District Court in Harris County, Texas, the policy covered up to $3 million, with a $100,000 deductible. The documents indicate that from May 21, 2014 to May 27, 2014, AFGlobal’s director of accounting received a series of emails from someone claiming to be Gean Stalcup, the CEO of AFGlobal.

“Glen, I have assigned you to manage file T521,” the phony message to the accounting director Glen Wurm allegedly read. “This is a strictly confidential financial operation, to which takes priority over other tasks. Have you already been contacted by Steven Shapiro (attorney from KPMG)? This is very sensitive, so please only communicate with me through this email, in order for us not to infringe SEC regulations. Please do no speak with anyone by email or phone regarding this. Regards, Gean Stalcup.”

Roughly 30 minutes later, Mr. Wurm said he was contacted via phone and email by Mr. Shapiro stating that due diligence fees associated with the China acquisition in the amount of $480,000 were needed. AFGlobal claims a Mr. Shapiro followed up via email with wiring instructions.

After wiring the funds as requested — sending the funds to an account at the Agricultural Bank of China — Mr. Wurm said he received no further correspondence from the imposter until May 27, 2014, when the imposter acknowledged receipt of the $480,000 and asked Wurm to wire an additional $18 million. Wurm said he became suspicious after that request, and alerted the officers of the company to his suspicions.

According to the plaintiff, “the imposter seemed to know the normal procedures of the company and also that Gean Stalcup had a long-standing, very personal and familiar relationship with Mr. Wurm — sufficient enough that Mr. Wurm would not question a request from the CEO.”

The company said it attempted to recover the $480,000 wire from its bank, but that the money was already gone by the 27th, with the imposters zeroing out and closing the recipient account shortly after the transfer was completed on May 21.

In a letter sent by Chubb to the plaintiff, the insurance firm said it was denying the claim because the scam, known alternatively as “business email compromise” (BEC) and CEO fraud, did not involve the forgery of a financial instrument as required by the policy. Continue reading →

Ransomware a Threat to Cloud Services, Too

Ransomware — malicious software that encrypts the victim’s files and holds them hostage unless and until the victim pays a ransom in Bitcoin — has emerged as a potent and increasingly common threat online. But many Internet users are unaware that ransomware also can just as easily seize control over files stored on cloud services.

ransomhandToni Casala found this out the hard way. Casala’s firm — Children in Film — works as an advocate for young actors and their families. The company’s entire operations run off of application hosting services at a managed cloud solutions firm in California, from QuickBooks to Microsoft Office and Outlook. Employees use Citrix to connect to the cloud, and the hosting firm’s application maps the cloud drive as a local disk on the user’s hard drive.

“We were loving that situation,” Casala said. “We can keep the computers here at work empty, and the service is very inexpensive when you compare it the cost of having more IT people on staff. Also, when we need support, they are very responsive. We don’t get farmed out to some call center in India.”

They were loving it, that is, until just before New Year’s Eve, when an employee opened an email attachment that appeared to be an invoice. Thirty minutes later, nobody in Casala’s firm could access any of the company’s 4,000+ files stored on the cloud drive.

“Someone in my office was logged into Outlook and opened up invoice attachment and BAM!, within 30 minutes, every single file on our Q drive had ‘vvv’ added as file extensions,” she said. Every single folder -had a file that said “help.decrypt,” essentially the attacker’s’ instructions for how to pay the ransom.

The cloud provider that Casala’s company is using was keeping daily backups, but she said it still took them almost a week to fully restore all of the files that were held hostage. She said the hosting service told her that the malware also disrupted operations for other customers on the same server.

Casala said her company got lucky on several fronts. For starters, the infection happened right before her firm closed down operations for the New Year’s break, so the outage was less of a disruption than it might normally have been.

More importantly, the malware that scrambled their files — a strain of ransomware called TeslaCrypt, contained a coding weakness that has allowed security and antivirus firms to help victims decrypt the files without paying the ransom. Users over at the computer help forum BleepingComputer have created TeslaDecoder, which allows victims to decrypt files locked by TeslaCrypt.

Casala said the hosting firm had antivirus installed on the server, but that the ransomware slipped past those defenses. That’s because the crooks who are distributing ransomware engineer the malware to evade detection by antivirus software. For more on how cybercriminals achieve that, see Antivirus is Dead: Long Live Antivirus.

The best defense against ransomware is a good set of data backups that are made each day — preferably to a device that is not always connected to the network. Unfortunately, this is often easier said than done, especially for small businesses. For many ransomware victims who do not have backups to rely upon, the choice of whether to pay comes down to the question of how badly the victim needs access to the ransomed files, and whether the files lost are worth more than the ransom demand (which is usually only a few hundred dollars in Bitcoin).

A Look Inside Cybercriminal Call Centers

Crooks who make a living via identity theft schemes, dating scams and other con games often run into trouble when presented with a phone-based challenge that requires them to demonstrate mastery of a language they don’t speak fluently. Enter the criminal call center, which allows scammers to outsource those calls to multi-lingual men and women who can be hired to close the deal.

Some of these call centers are Web-based, allowing customers to upload information about their targets to a service that initiates the call to a bank, credit provider, shipping company or dating scam victim (for more on the role played by call centers in dating schemes, see last week’s story, Fraudsters Automate Russian Dating Scams). Other call centers require customers to supply information about the target and the needed service via Jabber instant message. This post focuses on Web-based call services.

In the call service pictured below, we can see one user ordering a $250 radio-controlled toy Ford Mustang as a gift for someone’s kid for the holidays. The customer of the call service specifies the American Express card account to be used for the transaction, and requests that the order be expedited to a reshipping mule who will forward the goods to Russia. The status of the transaction indicates that this particular order was successfully placed on Jan. 7, 2016.

One of the cybercrime underground’s oldest call center services — CallMeBaby — serves a variety of swindles but specializes in helping criminals cash out dating scams. It charges $10 for each call in English, and $12 for calls in German, French, Italian, Spanish, Portuguese and Polish. Here’s an ad for the four-year-old service, which features an illustration of a blonde woman chatting with President Obama:

The Role of Phony Returns in Gift Card Fraud

On any given day, there are thousands of gift cards from top retailers for sale online that can be had for a fraction of their face value. Some of these are exactly what they appear to be: legitimate gift cards sold through third-party sites that specialize in reselling used or unwanted cards. But many of the more steeply discounted gift cards for sale online are in fact the product of merchandise return fraud, meaning consumers who purchase them unwittingly help thieves rob the stores that issued the cards.

giftcardsThis type of scam mainly impacts brick-and-mortar retailers that issue gift cards when consumers return merchandise at a store without presenting a receipt. Last week I heard from KrebsOnSecurity reader Lisa who recently went online to purchase a bunch of steeply discounted gift cards issued by pet supply chain Petco.

Lisa owns two Rottweilers that both eat a good chunk of their weight each month in dog food, so Lisa said she felt like she’d really hit on a bargain when she found a $165 Petco gift card for sale at a popular online gift card retailer for $120 (a nearly 30 percent discount on the value).

“When I went to Petco to get my monthly supply of dog food and snacks for my Rotties, I used my merchandise card and the manager shared with me that folks are stealing merchandise from one Petco store and returning the items to another without a receipt and then selling the cards to places like raise.com and cardpool.com at a discounted price,” Lisa recounted.

Petco’s official policy is that for returns more than 60 days after the purchase — or if the receipt is unavailable — the value of the goods returned will be refunded to a merchandise card. Lisa said she bought the Petco card from raise.com, but she said the company never disclosed that the card was a merchandise return card — a fact that was printed on the front of the card she received.

“I feel really bad now because my purchase of these cards may have contributed to unlawful activities,” Lisa said. “Even though I saved $40+, Petco actually lost money as a result.”

Neither Raise nor Petco responded to requests for comment. But a look at the available Petco cards for sale via one gift card tracking site — giftcardgranny.com — shows Petco cards routinely sell for at least 25 percent off their value.

In any case, this fraud scheme is hardly specific to Petco. Cards from Petsmart, a competitor that also offers merchandise return cards, generally sell at 20 percent off their value. Clothier H&M’s cards average about 30 percent off.

Contrast these discounts with those for gift cards from restaurants, fuel stations and other businesses that generally don’t have to deal with customer returns and you’ll notice two interesting patterns: For starters, the face value of the cards from merchants that don’t take customer returns are far more likely to be even amounts, such as $50, $25 and $40. The percentage off the face value also tends to be much lower — between 3 and 15 percent. For example, see the discount percentage and value of cards from Starbucks and Chevron.

“Twenty-five percent off is really high, and there aren’t many that offer that high of a discount,” said Damon McCoy, an assistant professor of computer science at New York University and an expert on fraud involving stored value cards. “Normally, it is around 5 percent to 15 percent.” Continue reading →

When Undercover Credit Card Buys Go Bad

I recently heard from a source in law enforcement who had a peculiar problem. The source investigates cybercrime, and he was reaching out for advice after trying but failing to conduct undercover buys of stolen credit cards from a well-known underground card market. Turns out, the cybercrime bazaar’s own security system triggered a “pig alert” and brazenly flagged the fed’s transactions as an undercover purchase placed by a law enforcement officer.

Law enforcement officials and bank anti-fraud specialists sometimes purchase stolen cards from crime forums and “carding” markets online in hopes of identifying a pattern among all the cards from a given batch that might make it easy to learn who got breached: If all of the cards from a given batch were later found to be used at the same e-commerce or brick-and-mortar merchant over the same time period, investigators can often determine the source of the card breach, alert the breached company and stem the flow of stolen cards.

Of course, such activity is not something the carding shops take lightly, since it tends to cut into their criminal sales and revenues. So it is that one of the more popular carding shops — Rescator — somehow enacted a system to detect purchases from suspected law enforcement officials. Rescator and his crew aren’t shy about letting you know when they think you’re not a real criminal. My law enforcement source said he’d just placed a batch of cards into his shopping cart and was preparing to pay for the goods when the carding site’s checkout page was replaced with this image:

A major vendor of stolen credit cards tries to detect suspicious transactions by law enforcement officials. When it does, it triggers this "pig detected" alert.

The shop from which my source attempted to make the purchase — called Rescator — is the same carding store that was the first to move millions of cards on sale that were stolen in the Target and Home Depot breaches, among others. I’ve estimated that although Rescator and his band of thieves stole 40 million credit and debit card numbers from Target, they only likely managed to sell between 1 and 3 million of those cards. Even so, at a median price of $26.85 per card and the median loss of 2 million cards, that’s still more than $50 million in revenue. It’s no wonder they want to keep the authorities out.

JPMorgan Hackers Breached Anti-Fraud Vendor G2 Web Services

Buried in the federal indictments unsealed this week against four men accused of stealing tens of millions of consumer records from JPMorgan Chase and other brokerage firms are other unnamed companies that were similarly victimized by the accused. One of them, identified in the indictments only as “Victim #12,” is an entity that helps banks block transactions for dodgy goods advertised in spam. Turns out, the hackers targeted this company so that they could more easily push through payments for spam-advertised prescription drugs and fake antivirus schemes.

g2webAccording to multiple sources, Victim #12 is none other than Bellevue, Wash. based G2 Web Services LLC, a company that helps banks figure out if a website is fraudulent or is selling contraband. G2 Web Services has not responded to multiple requests for comment.

In the final chapters of my book, Spam Nation: The Inside Story of Organized Cybercrime, I detailed the work of The International AntiCounterfeiting Coalition (IACC), a non-profit organization dedicated to combating product counterfeiting and piracy.

In 2011, G2 Web Services landed a contract to help the IACC conduct “test buys” at sites with products that were being advertised via spam. The company would identify which banks (mostly in Asia) were processing payments for these sites, and then Visa and MasterCard would rain down steep fines on the banks for violating their contracts with the credit card companies. The idea was to follow the money from schemes tied to cybercrime, deter banks from accepting funds from fraudulent transactions, and make it difficult for spammers to maintain stable credit card processing for those endeavors.

Prosecutors say the ringleader of the cybercrime gang accused of breaking into JPMC, Scottrade, E-Trade and others is 31-year-old Gery Shalon, a resident of Tel Aviv and Moscow. Investigators allege Shalon and his co-conspirators monitored credit card transactions processed through their payment processing business to attempt to discern which, if any, were undercover transactions made on behalf of credit card companies attempting to identify unlawful merchants. The government also charges that beginning in or about 2012, Shalon and his co-conspirators hacked into the computer networks of Victim-12 (G2 Web Services).

Shalon and his gang allegedly monitored Victim-12’s detection efforts, including reading emails of Victim-12 employees so they could take steps to evade detection.

“In particular, through their unlawful intrusion into Victim-12’s network, Shalon and his co-conspirators determined which credit and debit card numbers Victim-12 employees were using the make undercover purchases of illicit goods in the course of their effort to detect unlawful merchants,” Shalon’s indictment explains. “Upon identifying those credit and debit card numbers, Shalon and his co-conspirators blacklisted the numbers from their payment processing business, automatically declining any transaction for which payment was offered through one of those credit or debit card numbers.” Continue reading →

Ransomware Now Gunning for Your Web Sites

One of the more common and destructive computer crimes to emerge over the past few years involves ransomware — malicious code that quietly scrambles all of the infected user’s documents and files with very strong encryption.  A ransom, to be paid in Bitcoin, is demanded in exchange for a key to unlock the files. Well, now it appears fraudsters are developing ransomware that does the same but for Web sites — essentially holding the site’s files, pages and images for ransom.

Image: Kaspersky Lab

Image: Kaspersky Lab

This latest criminal innovation, innocuously dubbed “Linux.Encoder.1” by Russian antivirus and security firm Dr.Web, targets sites powered by the Linux operating system. The file currently has almost zero detection when scrutinized by antivirus products at Virustotal.com, a free tool for scanning suspicious files against dozens of popular antivirus products.

Typically, the malware is injected into Web sites via known vulnerabilities in site plugins or third-party software — such as shopping cart programs. Once on a host machine, the malware will encrypt all of the files in the “home” directories on the system, as well backup directories and most of the system folders typically associated with Web site files, images, pages, code libraries and scripts.

The ransomware problem is costly, hugely disruptive, and growing. In June, the FBI said it received 992 CryptoWall-related complaints in the preceding year, with losses totaling more than $18 million. And that’s just from those victims who reported the crimes to the U.S. government; a huge percentage of cybercrimes never get reported at all.

ONE RECENT VICTIM

On Nov. 4, the Linux Website ramsomware infected a server used by professional Web site designer Daniel Macadar. The ransom message was inside a plain text file called “instructions to decrypt” that was included in every file directory with encrypted files:

“To obtain the private key and php script for this computer, which will automatically decrypt files, you need to pay 1 bitcoin(s) (~420 USD),” the warning read. “Without this key, you will never be able to get your original files back.”

Macadar said the malware struck a development Web server of his that also hosted Web sites for a couple of longtime friends. Macadar was behind on backing up the site and the server, and the attack had rendered those sites unusable. He said he had little choice but to pay the ransom. But it took him some time before he was able to figure out how to open and fund a Bitcoin account.

“I didn’t have any Bitcoins at that point, and I was never planning to do anything with Bitcoin in my life,” he said.

According to Macadar, the instructions worked as described, and about three hours later his server was fully decrypted. However, not everything worked the way it should have.

“There’s a  decryption script that puts the data back, but somehow it ate some characters in a few files, adding like a comma or an extra space or something to the files,” he said.

Macadar said he hired Thomas Raef — owner of Web site security service WeWatchYourWebsite.com — to help secure his server after the attack, and to figure out how the attackers got in. Raef told me his customer’s site was infected via an unpatched vulnerability in Magento, a shopping cart software that many Web sites use to handle ecommerce payments.

CheckPoint detailed this vulnerability back in April 2015 and Magento issued a fix yet many smaller ecommerce sites fall behind on critical updates for third-party applications like shopping cart software. Also, there are likely other exploits published recently that can expose a Linux host and any associated Web services to attackers and to site-based ransomware. Continue reading →

TalkTalk, Script Kids & The Quest for ‘OG’

So you’ve got two-step authentication set up to harden the security of your email account (you do, right?). But when was the last time you took a good look at the security of your inbox’s recovery email address? That may well be the weakest link in your email security chain, as evidenced by the following tale of a IT professional who saw two of his linked email accounts recently hijacked in a bid to steal his Twitter identity.

Screen Shot 2015-10-24 at 10.08.01 AMEarlier this week, I heard from Chris Blake, a longtime KrebsOnSecurity reader from the United Kingdom. Blake reached out because I’d recently written about a character of interest in the breach at British phone and broadband provider TalkTalk: an individual using the Twitter handle “@Fearful“.

Blake proceeded to explain how that same Fearful account had belonged to him for some time until May 2015, when an elaborate social engineering attack on his Internet service provider (ISP) allowed the current occupant of the account to swipe it out from under him.

On May 11, Blake received a text message on his mobile stating that his Microsoft Outlook account password had been changed. A minute later, he got another text from Microsoft saying his two-factor authentication (texted login codes to his phone) had been removed. After that, he could no longer log in to his Outlook account because someone had changed his password and removed his recovery email address (changing it to a free and disposable yopmail.com account).

Minutes after that, someone tweeted out the message from his account: “This twitter account is officially operated by Elliott G.” The tweet prior to that one mentions Blake by name and is a response to an inquiry to the Microsoft Store before the account was taken. The alias on Blake’s @Fearful account was changed to “Glubz”.

Blake said it took some time to figure out how the miscreant had hijacked his Twitter and Outlook accounts. Turns out, the recovery email address that he’d supplied for his Outlook account was to an email address at his local ISP, and the attacker executed the first step in the hijack by tricking a customer service employee at the ISP into redirecting his messages.

The attacker, apparently another person with a British accent, called Blake’s ISP pretending to be Blake and said he was locked out of his inbox. Could the ISP please change the domain name system (DNS) settings on his domain and associated mail account?

According to Blake, an investigation into the incident at the ISP shows that the customer service rep asked the caller to verify any other email addresses associated with Blake’s ISP account, and after some waiting the support employee actually read off a few of them. Seconds later, the attacker sent an email to the support person that spoofed one of those email addresses. After that, Blake’s ISP complied with the request, changing the DNS settings on his account to settings that the caller supplied for an account at Namecheaphosting.com.

OG IS A THING

With all of the access to other accounts that one’s inbox affords, the attacker in this case could have done some serious damage and cost Blake a lot of money. So why was he only interested in Blake’s Twitter account?

Short usernames are something of a prestige or status symbol for many youngsters, and some are willing to pay surprising amounts of money for them. Known as “OG” (short for “original” and also “original gangster”) in certain circles online, these can be usernames for virtually any service, from email accounts at Webmail providers to social media services like Instagram, Snapchat, Twitter and Youtube. People who traffic in OG accounts prize them because they can make the account holder appear to have been a savvy, early adopter of the service before it became popular and before all of the short usernames were taken.

“I didn’t realize this was even a thing until all this happened,” Blake said of the demand for OG accounts. “It wasn’t until the day after my email accounts were hacked that I realized it was really my Twitter account he was after.”

As it happens, the guy who is currently squatting on Blake’s @Fearful Twitter account — a young wanna-be hacker who uses the nickname “Glubz” — is very publicly in the business of selling hijacked OG accounts. In the screen shot below, we can see Glubz on the script kiddie-friendly online community Hackforums promoting his “OG Store,” in which he sells “Snapchats,” Email accounts and “Youtubes” for $10-$40 apiece, payable via Bitcoin or PayPal. The bottom of the message includes a link to Glubz’s personal site — elliottg[dot]net (also hosted at Namecheaphosting.com). Continue reading →

ATM Skimmer Gang Firebombed Antivirus Firm

It’s notable whenever cybercime spills over into real-world, physical attacks. This is the story of a Russian security firm whose operations were pelted with Molotov cocktail attacks after exposing an organized crime gang that developed and sold malicious software to steal cash from ATMs.

molotovThe threats began not long after December 18, 2013, when Russian antivirus firm Dr.Web posted a writeup about a new Trojan horse program designed to steal card data from infected ATMs. Dr.Web received an email warning the company to delete all references to the ATM malware from its site.

The anonymous party, which self-identified as the “International Carders Syndicate,” said Dr.Web’s ATM Shield product designed to guard cash machines from known malware “threatens activity of Syndicate with multi-million dollar profit.”

The threat continued:

“Hundreds of criminal organizations throughout the world can lose their earnings. You have a WEEK to delete all references about ATM Skimmer from your web resource. Otherwise syndicate will stop cash-out transactions and send criminal for your programmers’ heads. The end of Doctor Web will be tragic.”

In an interview with KrebsOnSecurity, Dr.Web CEO Boris Sharov said the company did not comply with the demands. On March 9, 2014, someone threw a Molotov cocktail at the office of a third-party company that was distributing Dr.Web’s ATM Shield product. Shortly after that, someone attacked the same office again. Each time, the damage was minimal, but it rattled company employees nonetheless.

Less than two weeks later, Dr.Web received a follow-up warning letter:

“Dear Dr.Web, the International carder syndicate has warned you about avoidance of interference (unacceptable interference) in the ATM sphere. Taking into account the fact that you’ve ignored syndicate’s demands, we employed sanctions. To emphasis the syndicate’s purpose your office at Blagodatnaya st. was burnt twice.

If you don’t delete all references about atmskimmer viruses from your products and all products for ATM, the International carder syndicate will destroy Doctor Web’s offices throughout the world, In addition, syndicate will lobby the Prohibition of usage of Russian anti-viruses Law in countries that have representation offices of the syndicate under the pretext of protection against Russian intelligence service.”

After a third attack on the St. Petersburg office, a suspect who was seen running away from the scene of the attack was arrested but later released because no witnesses came forward to confirm he was the one who threw the bomb.

Meanwhile, Sharov said Dr.Web detected two physical intrusions into its Moscow office.

“This is an office where we have much more security than any other, but also many more visitors,” he said. “We had been on high alert after the fire bombings, and we’ve never had intrusions before and never had them after this. But during that period, we had three attempts to enter the perimeter and to do something bad, but I won’t go into details about that.”

Sharov said Dr.Web analysts believe the group that threatened the attacks were not cyber thieves themselves but instead an organized group of programmers that had sold — but not yet delivered — a crimeware product to multiple gangs that specialize in cashing out hacked ATM cards.

“We think this group got very nervous by the fact that we had published exactly what they’d done, and it was very untimely for them, they were really desperate,” Sharov said. “We believe our reports came out just after development of the ATM Trojan had finished but before it was released to customers.” Continue reading →
