In December, I wrote about how a Louisiana electronics testing firm was suing its bank, Capital One, to recover the losses after cyber thieves broke in and stole nearly $100,000. It looks like another small firm in that state that was similarly victimized by organized crooks also is suing Capital One to recover their losses.

Joseph Mier and Associates Inc., a real estate appraisal company based in Hammond, L.a., lost more than $27,000 last year when five four unauthorized automated clearing house (ACH) withdrawals were made from its accounts and sent to individuals around the United States.

“I immediately contacted the bank, and for about a week dealt with them to correct the error,” Owner Joseph Mier said. “Finally, they said, ‘From what we can see, whoever did this used your credentials, but nobody breached our system and we’re not responsible.’ I told them maybe they should change their slogan to, “Who’s in your wallet?'”

A spokesperson for Capital One said the company does not comment on pending litigation.

Fiserv to Banks: Stay on Outdated Adobe Reader

March 8, 2010

One of the nation’s largest providers of money-transfer and online banking services to credit unions and other financial institutions is urging customers not to apply the latest security updates for Adobe Reader, the very application most targeted by criminal hackers and malicious software.

At issue is a non-public advisory issued by Fiserv, a Fortune 500 company that provides bank transaction processing services and software to more than 16,000 clients worldwide.

A reader who works in security for a mid-sized credit union shared with me a notice posted prominently to the “collaborative care” portion of Fiserv’s site, a section dedicated to security and IT managers at partner financial institutions.

In the notice, dated Feb. 16, 2010, Fiserv instructed its customers to avoid the latest Adobe Reader updates, apparently in favor of one that was released two years ago:

“NOTICE: Please do not upgrade Adobe Acrobat Reader past Version 8.1.”

Yep, There’s a Patch for That

The average Microsoft Windows user has software from 22 vendors on her PC, and needs to install a new security update roughly every five days in order to use these programs safely, according to an insightful new study released this week.

The figures come from security research firm Secunia, which looked at data gathered from more than two million users of its free Personal Software Inspector tool. The PSI is designed to alert users about outdated and insecure software that may be running on their machines, and it is an excellent application that I have recommended on several occasions.

Stefan Frei, Secunia’s research analyst director, said the company found that about 50 percent of PSI users have more than 66 programs of installed.

“Those programs come from more than 22 vendors, so as a first order estimate the number of different vendors you have on your box is the number of different update mechanisms you have to master,” Frei said. “This is doomed to fail.”

‘Mariposa’ Botnet Authors May Avoid Jail Time

March 4, 2010

Three Spanish men were arrested last month for allegedly building an international network of more than 12 million hacked PCs that were used for everything from identity theft to spamming. But according to Spanish authorities and security experts who helped unravel the crime ring, the accused may very well never see the inside of a jail cell even if they are ultimately found guilty, due to insufficient cyber crime legislation in Spain.

According to Spanish security firm Panda Security, the massive botnet, dubbed “Marioposa” (Spanish for “butterfly”), was rented out to criminals as a delivery platform for installing malicious software such as the data-stealing ZeuS Trojan and pay-per-install toolbars. Panda said the gang also stole directly from victim bank accounts, using money mules in the United States and Canada, and laundered stolen money through online gambling Web sites (pictured above is a screen shot of the Web site the men created where would-be Mariposa customers could visit for information on purchasing access to the botnet and other criminal services.)

Panda said Mariposa helped crooks steal sensitive data from more than 800,000 victims, including home users, companies, government agencies and universities in at least 190 countries. Spanish police estimate that at least 600,000 of the victimized PCs belong to Spanish citizens, and yet they concede it may be extremely challenging to put the men in jail if they are convicted at trial.

“It is almost impossible to be sent to prison for these kinds of crimes in Spain, where prison is mainly for serious crime cases,” said Captain Cesar Lorenzana, deputy head technology crime division of the Spanish Civil Guard. “In Spain, it is not a crime to own and operate a botnet or distribute malware. So even if we manage to prove they are using a botnet, we will need to prove they also were stealing identities and other things, and that is where our lines of investigation are focusing right now.”

Krebsonsecurity Author Twice Honored

There is perhaps no greater compliment than to have your most esteemed peers recommend your work.  I am now blogging from the RSA Conference in San Francisco, and over the past two days krebsonsecurity.com has received two peer recognition awards, one from the SANS Institute – among the nation’s top security research and training groups – and another from the Security Bloggers Network, an organization that has sought to recognize blogs that provide valuable content on computer security issues.

The SANS Institute polled 75 cybersecurity journalists and asked them to rank the top peers in their field. True to form, I showed up late to the awards ceremony on Tuesday, and Alan Paller, director of research for SANS, called me up on stage and said I’d received twice as many votes as the next guy in the contest, Robert McMillan, a reporter whose work is almost certainly the most widely syndicated and quoted of virtually anyone in this industry. Likewise, I am proud to have shared this honor with reporters whose work I recommend and admire, including USA Today’s Byron Acohido, Wired.com’s Kim Zetter, as well as Dan Goodin from The Register.

In related news, the delegates who were party to the Security Bloggers Awards at RSA this year picked krebsonsecurity.com as the top “non-technical security blog.” Somehow, I managed to show up late for this as well. Again, it was wonderful to have been nominated alongside security bloggers such as Taosecurity’s Richard Bejtlich, and security curmudgeon-in-chief Bruce Schneier.

Regulators Revisit E-Banking Security Guidelines

March 3, 2010

Prodded by incessant reports of small- to mid-sized business losing millions of dollars at the hands of organized cyber criminals, federal regulators may soon outline more stringent steps that commercial banks need to take to protect business customers from online banking fraud and educate users about the risks of banking online.

At issue are the guidelines jointly issued in 2005 by five federal banking regulators under the umbrella of the Federal Financial Institutions Examination Council (FFIEC). The guidance was meant to prod banks to implement so-called “multifactor authentication” — essentially, to require customers to provide something else in addition to a user name and password when logging into their bank accounts online, such as the output from a security token.

The FFIEC didn’t specify exactly how the banks had to do this, and indeed it left it up to financial institutions to work out the most appropriate approach. However, many banks appear to have gravitated toward approaches that are relatively inexpensive, easy to defeat, and that may not strictly adhere to the guidance, such as forcing customers to periodically provide the answer to “challenge questions” as a prerequisite to logging in to their accounts online.

Unfortunately, as I have documented time and again, organized computer criminals are defeating these solutions with ease. Experts say part of the problem is that few of these solutions can protect customers whose systems are already infected with password-stealing malicious software. What’s more, few banks have put in place technology on their back-end systems to monitor customer transactions for anomalies that may indicate fraudulent activity, much in the way that the credit card industry sifts through data in real time and alerts the customer if a transaction or set of transactions radically deviate from that customer’s usual purchasing habits.

Last month, krebsonsecurity.com, interviewed Robert C. Drozdowski, a senior technology specialist with the Federal Deposit Insurance Corporation (FDIC). Drozdowski told me that the banking regulators recently convened a series of meetings with banks and security technology providers to figure out whether additional guidance would help banks do a better job of protecting their commercial customers. I asked him about the current state of these regulations and what we might expect from banking regulators in the months ahead on this issue. What follows is a portion of that discussion.

MS: Be Careful With Those Function Keys

March 2, 2010

Microsoft Corp. has a message for Windows 2000, XP and Server 2003 users: If you browse the Interwebs with Internet Explorer 6, 7, or 8, take care to ignore any prompts that ask you to hit the F1 key on your keyboard, as doing so may be unhealthful to your PC.

It turns out that there is a security flaw in the way these operating systems + browser versions process “Windows Help files” in such a way that is entirely unhelpful. That is, clicking on the F1 key when presented with a specially crafted pop-up box prompting you to do so could allow criminals to download and install malicious software to your computer.

Thankfully, most Windows users are more likely to locate the “any” key on their systems before they realize that the “Function 1” key is but the first of 12 such keys situated just above the left-to-right number keys on the standard Windows keyboard. Indeed, most Windows users’ first experience with these function keys is when something goes wrong with Windows.

In a security advisory issued Monday, Microsoft said it may at some point issue a software update to address this shortcoming. Redmond’s advisory on this topic is available here. The organization responsible for this warning — Polish security firm iSec Security Research — has a bit more information here on the ins and outs of this bug.

Talking Bots with Japan’s ‘Cyber Clean Center’

March 1, 2010

I’ve grown fascinated over the years with various efforts by Internet service providers to crack down on the menace from botnets, large groupings of hacked PCs that computer criminals remotely control for a variety of purposes, from spamming to hosting malicious software and attacking others online. Indeed, the botnet problem has become such a global menace that entire countries are now developing anti-botnet programs in collaboration with domestic ISPs.

One of the more unique and long-running examples of this is Japan’s “Cyber Clean Center,” (referred to hereafter as CCC) a little-known effort by the Japanese Computer Emergency Response Team Coordination Center (JP-CERT) and a collection of 76 Japanese ISPs covering 90 percent of the nation’s Internet users.

Participating ISPs that have customers with botted PCs may send those users an e-mail — and in some cases a letter via postal mail — instructing them to visit the CCC’s Web site, and download and run a cleanup tool developed by the JP-CERT in coordination with Trend Micro, the dominant anti-virus and computer security firm in Japan.

Relatively few of the thousands of U.S.-based ISPs have such programs in place, or if they do then not many have been willing to discuss them publicly. Some notable exceptions are Cox, Comcast (which is rolling out a trial bot infection notification system), and Qwest (if I missed any other biggies, readers please set me straight).

It’s unfortunate that such programs aren’t more widely emulated, because a majority of the world’s bot problem begins and ends here in the United States.  According to a recent report (.pdf) by McAfee, the United States is home to the second largest pool of botted PCs — 2nd only to China — and is the world’s biggest exporter of junk e-mail.

Microsoft Ambushes Waledac Botnet, Shutters Whistleblower Site

February 25, 2010

Microsoft’s lawyers this week engineered a pair of important takedowns, one laudable and the other highly-charged. The software giant orchestrated a legal sneak attack against the Web servers controlling the Waledac botnet, a major distributor of junk e-mail. In an unrelated and more controversial move, Redmond convinced an ISP to shutter a popular whistleblower Web site for hosting a Microsoft surveillance compliance document.

On Feb. 22, a federal judge in Virginia granted a request quietly filed by Microsoft to disconnect 277 Internet domains believed to be responsible for directing the daily activities of the Waledac botnet, estimated to be one of the ten-largest spam botnets in existence today and responsible for sending 1.5 billion junk e-mails per day. Microsoft said it found that between December 3-21, 2009, approximately 651 million spam emails attributable to Waledac were directed to Hotmail accounts alone, including offers and scams related to online pharmacies, imitation goods, jobs, penny stocks and more.

N.Y. Firm Faces Bankruptcy from $164,000 E-Banking Loss

February 24, 2010

A New York marketing firm that as recently as two weeks ago was preparing to be acquired now is facing bankruptcy from a computer virus infection that cost the company more than $164,000.

Karen McCarthy, owner of Merrick, N.Y. based Little & King LLC, a small promotions company, discovered on Monday, Feb. 15 that her firm’s bank account had been emptied the previous Friday. McCarthy said she immediately called her bank – Cherry Hill, N.J. based TD Bank – and learned that between Feb. 10 and Feb. 12, unknown thieves had made five wire transfers out of the account to two individuals and two companies with whom the McCarthys had never had any prior business.

“She was told to go to the branch next day, and she did, and the people at the branch were very nice, apologetic, and said, ‘Whatever happened, we’ll replace it,’” Karen McCarthy’s husband Craig said. “She called them up on Wednesday, and they gave her the runaround. Then she finally got to talk to someone and they said ‘We don’t see the error on our side.’”

Immediately before the fraud occurred, Mrs. McCarthy found that her Windows PC would no longer boot, and that the computer complained it could not find vital operating system files. “She was using it one day and then this blue screen of death just came on her screen,” said a longtime friend who was helping McCarthy triage her computer.

Later, McCarthy’s friend would confirm that her system had been infected with the ZeuS Trojan, a potent family of malware that steals passwords and lets cyber thieves control the infected host from afar. ZeuS also includes a feature called “kill operating system,” which criminals have used in prior bank heists to effectively keep the victim offline and buy themselves time to make off with the cash.

Karen McCarthy said TDBank has dug in its heels and is now saying it has no responsibility for the loss.

“They feel that because [the thieves] compromised my computer that it’s my responsibility and that I should look into my insurance, but I don’t have insurance,” McCarthy said. “I had a company that was interested in purchasing us, but they’re not going to do that now.  I’m basically looking at bankruptcy, because I have very little money to operate on now.”

Krebsonsecurity spoke briefly with John G. McCluskey, vice president of TDBank’s corporate security and investigations. McCluskey referred all questions about the incident to the bank’s marketing department, which hasn’t returned calls seeking additional information and comment.
