Online Thieves Take $205,000 Bite Out of Missouri Dental Practice

Organized computer criminals yanked more than $200,000 out of the online bank accounts of a Missouri dental practice this month, in yet another attack that exposes the financial risks that small- to mid-sized organizations face when banking online.

Dentists working at the Smile Zone, a Springfield, Mo. based dental practice that caters specifically to the needs of children, weren’t exactly all smiles on March 22. That was the day unidentified crooks sent at least $205,000 of the practice’s money to nearly a dozen individuals around the country.

Eric Hudkins, the office manager and husband of one of the dentists at Smile Zone, said the money was taken in 11 different transfers, including three large wires. Once again, it seems the attack was carried out with the help of money mules, willing or unwitting individuals hired through work-at-home job schemes over the Internet and lured into helping the attackers launder the stolen money.

“I’ve got the names, account numbers, and phone numbers for most of them, and have even looked some of them up on Facebook,” Hudkins said of the co-conspirators. “The bank talked to two of the [mule] account holders and asked them why they opened the account, who it was for, that kind of thing. Both of them said they’d had their resumes out on careerbuilder.com or monster.com and that someone they’d never met contacted them and offered to help them make some money.”

Hudkins said he contacted the FBI, and that the agent he spoke with told him the FBI wouldn’t open a case on the theft unless it was over $500,000 in losses. As it stands, he was told, his case would be lumped into a group of similar investigations that is being run out of an FBI task force in Omaha, Nebraska. It also appears there is little appetite for prosecuting the money mules, he said.

“The FBI said prosecuting these [mules] for doing anything wrong is near impossible,” Hudkins said.

Microsoft to Issue Emergency IE Fix

March 29, 2010

Microsoft Corp. said today it plans to break from its regularly scheduled monthly software update cycle to issue a patch on Tuesday for a security hole in its Internet Explorer Web browser that hackers have been exploiting lately.

Microsoft normally releases security updates on “Patch Tuesday,” the second Tuesday of each month. But this Tuesday, Mar. 30, Microsoft will release a cumulative update for Internet Explorer that fixes a critical software flaw in IE 6 and IE 7. The browser flaw lets hackers break into vulnerable systems remotely, with little help from users.

Redmond initially said it was aware of only “targeted” attacks that leveraged this vulnerability. But Microsoft’s statement that accompanied this announcement suggests that these attacks may have become more widespread.

“We have been monitoring this issue and have determined an out-of-band release is needed to protect customers,” Microsoft said in a statement on its Security Response Center blog today.

Tomorrow’s update will correct that flaw, as well as at least nine other security holes in IE that Microsoft had planned to patch on the next official Patch Tuesday (April 13).

Removing Viruses from a PC That Won’t Boot

One of the more common questions I hear from readers with computer virus infections is, “How do I get rid of a virus if I can’t even boot up into Windows to run an anti-virus scan?” Fortunately, there are a number of free, relatively easy-to-use tools that can help on this front.

The tools in this review are known as a “rescue CDs.” These are all free, Linux-based operating systems that one can download and burn to a CD-Rom. Once you’ve configured your PC to boot from the CD you’ve just burned, you can use the CD to scan your hard drive, and — depending on the type of rescue CD you choose — even copy files to a removable drive.

Would You Have Spotted this ATM Fraud?

ATM skimmer found on a Wachovia ATM in Alexandria Feb. 28.

The stories I’ve written on ATM skimmers — devices criminals can attach to bank money machines to steal customer data — remain the most popular at Krebs on Security so far. I think part of the public’s fascination with these fraud devices is rooted in the idea that almost everyone uses ATMs, and that it’s entirely possible to encounter this type of sneaky, relatively sophisticated form of crime right in our own neighborhoods.

Indeed, police in Alexandria, Va. — just a couple of miles to the East of where I reside — recently were alerted to a skimmer found on an ATM at a Wachovia Bank there. The device reportedly was discovered On Sunday, Feb. 28, at around 1:30 p.m., by an ATM technician (no one I’ve asked has been able to explain why the technician was there on a Sunday in the first place, but I digress). According to the Alexandria Police, the technician spotted the skimming device attached to the card reader on the ATM, snapped some pictures of it, and then went inside the bank to notify the bank’s security office. When he returned a few minutes later, the skimmer had been removed.

ATM skimmer found on a Wachovia ATM in Alexandria Feb. 28.

Skimmers are typically placed at the mouth of the card acceptance slot, and designed to record the data off of the magnetic strip on the back of a customer’s ATM card when he or she inserts the card into the machine. Usually, thieves will plant another device used to record the customer’s PIN, such as a hidden camera or a PIN pad overlay. With the data from the magnetic strip and the customer’s PIN, the thieves can later clone that ATM card and use it to withdraw cash. The police in this case couldn’t say whether there was also a PIN stealing apparatus attached to the ATM, although it seems likely that the technician simply overlooked it.

Cmdr. Jody D. Donaldson, head of the Alexandria Police Department’s Media Services Unit, said crooks sell skimmers in different adaptations and colors depending on the make and model of the ATM that their thieving customers want to target. The skimmer attached to the front of the Wachovia ATM for example, was manufactured for a specific model of Diebold ATMs, Donaldson said.

Donaldson said several customers have come forward to report fraudulent charges on their bank cards, with current losses from the incident estimated at more than $60,000.

Read on after the jump about how the skimmer used in this attack matches a model sold online by criminals in rent-to-own kits, complete with instructional videos and software that divvies up the stolen data.

Cybersecurity Policy Roundup

There are several cybersecurity policy issues on Capitol Hill that are worth keeping an eye on. Lawmakers in the Senate have introduced a measure that would call for trade restrictions against countries identified as hacker havens. Another proposal is meeting resistance from academics who worry about the effect of the bill’s mandatory certification programs for cyber security professionals.

As reported by The Hill newspaper, Senators Orrin Hatch (R-Utah) and Kirsten Gillibrand (D-NY) have introduced The International Cybercrime Reporting and Cooperation Act, a bill that would penalize foreign countries that fail to crack down on cyber criminals operating within their borders.

AVprofit: Rogue AV + Zeus = $

March 24, 2010

The presence of rogue anti-virus products, also known as scareware, on a Microsoft Windows computer is often just the most visible symptom of a more serious and insidious system-wide infection. To understand why, it helps to take a peek inside some of the more popular rogue anti-virus distribution networks that are paying people to peddle scareware alongside far more invasive threats.

Distributors or “affiliates” who sign up with avprofit.com, for example, are given access to an installer program that downloads not only rogue anti-virus but also ZeuS, a stealthy piece of malware that specializes in mining online banking credentials from infected PCs. ZeuS is the very piece of malware directly responsible for helping thieves steal tens of millions of dollars from small to mid-sized businesses over the past year.

Avprofit says it will pay affiliates roughly $1,000 for every 1,000 times they distribute this installer program, or about $1 per install. Typically, affiliates will embed these installers at porn sites or bundle them with programs seeded on peer-to-peer file-sharing services. The nightmare for the victim starts when he or she responds to the fake anti-virus pop-up warning of supposed threats resident on the victim’s PC, by agreeing to download and run a scanning tool.

What’s remarkable about this entire ecosystem is that in many cases, victims who have this installer run on their systems often end up paying for the rogue anti-virus, in addition to unknowingly giving up their passwords and handing complete control of their computer to the bad guys running this distribution network.

Bring Back ‘Live’ Web Chats?

I’ve been hearing from a number of readers who followed me here from the Security Fix blog at The Washington Post, asking if I plan to resume my bi-weekly “live” chats wherein I attempt  to field questions from readers about security, privacy and other tech-related matters.

I hosted roughly 50 of these live Web chats with readers between Jan 2008 and the end of 2009. They were usually fun, but almost always took up a lot of time. I’m amenable to restarting them at Krebs on Security, but I’d like to get a better feel for public interest in this. So, I’ll put it to a vote. Please take a moment to list your response in the poll below.

An Arkansas public water utility and a New Jersey town are the latest victims of an organized cyber crime gang that is stealing tens of millions of dollars from small to mid-sized organizations via online bank theft.

On Thursday, officials in Egg Harbor Township, N.J. acknowledged that a sizable amount of money was taken in an “outside intrusion into a municipal banking account,” suggesting in public statements that computer criminals were responsible.

On Monday, details began to emerge that implicate the work of the same gang that Krebs on Security has been tracking for close to a year now.

Mayor James J. “Sonny” McCullough confirmed that the thieves took close to $100,000 from town coffers, sending the money in sub-$10,000 chunks to individuals around the country who had no prior businesses with Egg Harbor.

McCullough said the town is working with local authorities and the FBI.

“There’s a possibility that the bank will be able to [retrieve] some of the money,” McCullough told Krebs on Security.

Bad BitDefender Antivirus Update Hobbles Windows PCs

March 20, 2010

A faulty update  is being blamed for incapacitating an untold number of Microsoft Windows systems running anti-virus software from BitDefender.

BitDefender says the problem occurred Saturday morning with a faulty update for 64-bit Windows systems that  caused multiple Windows and BitDefender files to be quarantined. The bad update causes the anti-virus program to flag thousands of legitimate Windows and BitDefender program files as a threat called “”FakeAlert.5”.

The Romanian software firm  said the glitchy update has been removed and that the company is working on a fix for the problem.  BitDefender’s user forum has lit up with complaints from customers, and the company appears to be fielding quite a number of inquiries on the problem via its Twitter page.

“We are creating a patch that will restore all quarantined files,” the company said in a statement on its site. “The patch will be available shortly. We apologize for this error and we will work to prevent this from occurring again in the future.”

BitDefender has posted partial recovery instructions for users who are having trouble booting up Windows after this bad update, although several apparent users commenting on the company’s Twitter feed indicated they were still unable to boot after following the instructions.

Meanwhile, Bitdefender representatives on Twitter are warning users that malware writers already are taking advantage of the situation, and urging users to download the fix — whenever it is made available — only from BitDefender’s Web site.
