Banks: Losses From Computer Intrusions Up in 2007
U.S. financial institutions reported a sizable increase last year in the number of computer intrusions that led to online bank account takeovers and stolen funds, according to data obtained by Security Fix. The data also suggest such incidents are becoming far more costly for banks, businesses and consumers alike.
The unusually detailed information comes from a non-public report assembled by the Federal Deposit Insurance Corporation, the federal entity that oversees and insures more than 9,000 U.S. financial institutions. The statistics were gathered as part of a routine quarterly survey called the Technology Incident Report, which examines so-called suspicious activity reports (SARs). In this case, SARs that were filed in the 2nd Quarter of 2007. SARs are federally mandated write-ups that banks are required to file anytime they spot a suspicious or fraudulent transaction that amounts to $5,000 or more.
A copy of the report was provided by a trusted source who asked to remain anonymous. An FDIC spokesperson could not be immediately reached for comment.
While the number of reported computer intrusion-related SARs (536) paled in comparison to the leading SARs categories - mortgage loan fraud (12,554) and check fraud (17,558) - the FDIC said financial crime aided by computer intrusions is growing at a rapid pace. Further, it noted that the mean (average) loss per SAR from computer intrusions was roughly $29,630 -- almost triple the estimated loss per SAR during the same time period in 2006 ($10,536).
According to George Manning, the author of the book "Financial Investigation and Forensics," federal banking statutes define computer intrusion for the purposes of SAR reporting as one or more of the following activities:
1) Gaining access to a computer system of a financial institution to steal, procure, or otherwise affect funds of the institution or the institution's customers;
2) Attempting to remove, steal, procure or otherwise affect critical information of the institution including customer account information;
3) Activities that damage, disable or otherwise affect critical systems of the institution.
Manning notes in his book that for the purposes of this reporting requirement, computer intrusion does not mean attempted intrusions of Web sites or other non-critical information systems of the institution that provide no access to institution or customer financial or other critical information.
Anyway, back to the interesting bits: The report indicates that in most cases, banks are at a loss to say exactly how cyber crooks are stealing the funds. The report indicates that the 80 percent of the computer intrusions were classified as "unknown unauthorized access - online banking," and that "unknown unauthorized access to online banking has risen from 10 to 63 percent in the past year."
Still, the FDIC indicates that a large share of the unknown losses most likely resulted from malicious data-stealing programs surreptitiously installed on customer PCs by cyber crooks. The FDIC wrote that "in several significant cases where the source of the computer intrusions was identified suggest that Trojan horses and key logging software infecting the customers' computers might also be responsible for a large portion of the unknown unauthorized access to online bank accounts."
Indeed, one of many confidential case studies in the report told the plight of a U.S. business that lost $188,000 in July 2007 after an employee infected a company computer with a password-stealing Trojan horse program. The malicious program arrived as an attachment in an e-mail purported to have been sent by the Better Business Bureau. In this "spear phishing," campaign, the company and the recipient were both named in the body of the e-mail, and the recipient was urged to open the attachment to view a complaint lodged against the company.
Security Fix has written about this series of attacks spoofing the BBB, as well as a similarly successful spear phishing malware attacks that spoofed the Federal Trade Commission.
Of those computer intrusion-related SARs that were identified, online bill payment applications were most frequently targeted by cyber thieves, the FDIC found. However, unauthorized access to wire transfers and automated clearinghouse (ACH) payments caused the most losses to financial institutions in the computer intrusion category, mainly because ACH and wire transfers give the banks less time to detect and recover from unauthorized access.
Another case study cites an unnamed financial institution that had 14 customer account takeovers as a result of spyware infestations that recorded keystrokes on customer PCs, stolen credentials that allowed the crooks to initiate a series of fraudulent ACH transfers out of the victims' corporate accounts into accounts set up and controlled by the attackers. All told, in the six months between October 2006 and April 2007, the attackers managed to steal $289,000 from the 14 victims.
Avivah Litan, a financial fraud analyst with Gartner Inc., said unauthorized wire transfers disproportionately impact small to medium sized businesses that may be using online banking but do not have the same stringent financial controls in place at many larger corporations.
"It's interesting to hear them at least privately admitting that the ACH and wire transfer system is really broken, and that there are a lot of new Trojans targeting the banks now," Litan said. "That's very much in line with everything I'm seeing." (Security Fix has covered ACH fraud in previous posts. See this piece from last May for more perspective on Litan's quote here).
Litan said small to mid-sized businesses that bank online typically are allowed to transfer relatively large amounts with ease, though they have far fewer protections than consumer accounts when fraudulent transactions are at stake. In fact, most companies have just two business days to report fraudulent or unauthorized transfers in order to have a decent chance at getting the charges reversed. In contrast, consumers generally are allowed up to 60 days to report such activity, Litan said.
Another aspect of this report should be closely noted: If the number of SARs related to computer intrusions seems low, remember that banks are required to file SARs only when the amount exceeds $5,000. As such, most the data included in this FDIC report probably comes as a result of fraud perpetrated against businesses, not consumers.
According to a Gartner study of 4,500 adult consumers for the year ending Aug. 2007, the average loss to consumers from online fraud was around $1,500 per victim on average, well below the SARs reporting threshold. To better round out the consumer side of things, consider that Gartner's study found that 2.2% -- or an estimated 3.85 million adults -- said they were a victim of 'abuse of an existing checking or savings account, where a thief transferred money out of your account." Of this population: about 1.1 million had the fraud occur within the 12 months prior to August 2007.
I've chosen not to post a copy of the FDIC report here because it includes some general but potentially sensitive information related to ongoing law enforcement investigations into several recent and costly cyber fraud incidents. However, I'd argue that absent the case study data, there is absolutely no reason this aggregate data should not be made public on a regular basis. But of course any regular reader of this blog is already familiar with my views on this subject.
Some other data points from the report: Regarding data breaches by businesses, governments and other organizations in general, the FDIC writes:
- The number of consumer records breached doubled compared to prior quarters, which will impact ID theft, account takeovers, and account application fraud in the future. Fewer retailer payment card data breaches during the quarter caused lower losses to financial institutions. Retailers are resisting payment card industry (PCI) data security standards, which could lead to lower compliance, additional breaches, and more counterfeit card losses absorbed by card-issuing institutions.
- The level of identity theft reports by financial institutions was high, but the growth rate has slowed. This trend may change in the future because of a large spike in the number of consumer records compromised and reported in the media during the quarter.
With respect to credit and debit card fraud, as well as ID theft cases, the report notes:
-Credit card fraud and counterfeit card reports increased slightly. Losses from counterfeit cards, which were extremely high during the 1st quarter, subsided during the current quarter.

We've made this too easy for the bad guys on so many levels. There is plenty of blame to go around, from the financial institutions themselves, to government, law enforcement on down to individual consumers.
I'm at a loss to try to explain why, other than to chock it up to plain old ignorance and/or laziness in taking security seriously. There seems to be a pass the buck mentality happening here instead of each entity truly doing their share to control and reduce the weaknesses in the system.
As consumers, we need to take proactive steps in securing our computers, using caution in every financial transaction and carefully monitoring all financial accounts for fraudulent activity. An ounce of prevention is worth a pound of cure!

Last year an FFIEC guidance for strong authentication on online bank accounts went into effect. Effectively, all banks are supposed to have two factor authentication for online banking customers. If appropriately implemented, this should have a dramatic effect on the ability of criminal to commit this kind of fraud.
Personally, I've seen only sporadic adoption of this guidance, and many that have seem to be trying to "get around the rules" and comply with a narrow reading of the guidance rather than the spirit of it which is to curtail the impact of online banking attacks on individual user accounts.
I would be interested in knowing whether this guidance is being enforced, especially regarding those banks where incidents occur - whether reported by customers or as required by the banks themselves. Similarly, it would be interested to see if there is a difference in the fraud at banks who do comply compared to those who do not.
It seems regulations are in place to deal with at least part of this issue, but either the system takes too long to "catch up" with violators, the rules are simply being violated, or perhaps the guidance needs to be strengthened.

There is not a sufficient amount of information available to users of Internet Protection programs on how to effectively configure a firewall as well as other means of protection. The inability of users to adequately configure their protective programs is due to ignorance of the intricacies of internet communications. This type of information should be readily available on the websites of the protection providers and should not be written in technical gobble-de-gook.

I received a bogus email which appeared to be from my bank. It was written in such a way that it almost fooled me into giving my bank access information. The bank logo and links looked exactly as if it were from my bank. Since these emails and web sites can be traced, we should have stiff penalties for these crimes, even if they originate outside the country. I do not think enough is being done to stop it.

regarding the gentleman's comment:
"Since these emails and web sites can be traced, we should have stiff penalties for these crimes, even if they originate outside the country."
this assumes that the owner of the web site is the perpetrator of the crime - more often than not the bad guys use other people's computers as their proxy - rarely are these people silly enough to use their own- as such prosecuting the "web site" owner would do nothing to discourage the bad guys
and of course the same for email..

Excellent work. Finally there is "publicly available" data from another country than the UK. (UK APACS has been publishing this data for years.)
One question: when looking at the first figure (the bar chart), I really wondered what the story is for 2004? If you are claiming a rapid rise of this type of incident, how are we to understand this when comparing 2007 (536 incidents) to 2004 (503 incidents)?
It reminds me of all the claims about rapidly rising costs of security breaches, while the CSI survey has been showing the exact opposite trend: steadily declining reported losses. Only last year was there a break in this trend, as respondents reported an increase in damages. Still, last years reported losses still pale in comparison to those reported in 2001.
But because this doesn't fit with the currently dominant narrative of rapidly rising online crime, which people try to explain away these figures. Mind you, the narrative might be correct, but I think these anomalies require a better explanation than they are currently getting.
So to sum up: what is the deal with 2004?

Is there anything the average consumer can do about this? How and to whom should we express our concern?
I have a hard-to-guess email address for commerce that I don't post anywhere (so I get spam about four times a year). Our computer uses a firewall, and we're smart about not visiting suspect websites. Our banking website uses one of those "identify your picture and password phrase" security features, and we don't save financial information on the desktop. Am I missing anything?

Excellent articles!
I use a Windows computer for online banking at my bank, BB&T. I am rather knowledgeable about computer security and take steps to protect my computer against infection, including the usual combination of a firewall and an anti-virus (updated daily). Also, I use a LUA [1].
My bank has a rather complicated policy about something it calls "wire transfer fraud." Suppose my computer became infected, and a hacker stole my money. Question: Would the bank pick up the tab, or would I have to absorb the loss?
[1] A so-called "Limited User Account" offers considerable hardening against infection, especially "drive-by downloads." Please see

A detail left out is that payment card industry (PCI) data security standards are written to place all the burden on the merchant while the banks do nothing meaningful to upgrade the 1960's technology.
Technology exists today where every time you would use your card at a data connected store - your use number would change. The number would be visible on a super thin LCD or E-paper display on the card.
Thus every time you use your card, except on phone or web purchases, the number changes. If you chose, one could also add biometric info to the card.
The silly system in place today, makes simply copying the numbers off a card all that is needed to commit fraud.

Brian:
Thanks for this information, and for addressing the question of why you chose not to make the report available. I would have preferred that you had made it available, but at least we understand your reasoning.
SARs are one of the very few good sources of fraud data, and the closed-mouth policy of the regulators is frustrating for those looking to make risk management decisions based on something other than the say-so of Gartner press releases, in-house data, and facts gleaned from off-the-record conversations with colleagues.

I can tell you that this issue is directly related to user education and training. People want their computers to be as easy to operate as their television, and it isn't. Computers should be looked at like automobiles in todays data centric environment. If you aren't careful, you can hurt yourself and others.
I have seen bank customers targeted by trojans, whose users were compromised. True two factor authentication with something you have and something you know, like a token, is good but only if your computer or other endpoint is trusted. Even if you have a token, a thief could wait until you enter your "secure" two factor credentials, and THEN steal your money.
There needs to be accountability had by the finance industry, and software manufacturers. Demand action, because nothing will improve unless consumers demand better protection.
In the absence of trusted networks to conduct transactions, maybe finance companies should distribute "secure" virtual environments on a USB drive. Of course my management told me "no one" would bother with that!

Modern Trojans are detected only by a fraction of the anti-virus programs on the market, and even then, the AV often needs an update before it can detect the threat of the day. By that time, the Trojan is installed and includes a rootkit which makes it impossible to remove, except by a complete reformat.
The bottm line is that you shouldn't use Windows to do online banking. Use Linux, even if you have to dual boot. Linux is immune to the password-grabbing malware that infect Windows.

Wisdom follows, pay attention!
The defence is easy: no online transfers to anywhere in the former Soviet Union (the so called CIS states). No transfers to companies or persons that have slavic-sounding names. The vast majority of hackers and virus writers are russians, that is undeniable fact. No transfer to Brazil, because most of banking data stealing trojans are authored in Sao Paolo.
If customer wants to deal with ex-soviet or brazilian partner, kindly inform him/her to turn up in person at the counter to do the transaction or and submit an attorney counter-signed waiver that he/she is aware of risks and takes full reposibility for any losses.
Any pending transfer request to people or firm hispano-sounding name should be routed to client support and the alleged sender should be called and asked to veriy if he/she really wanted to do that. If you have manpower, do the same with communist china-bound transactions, because a lot of trojans are mad in PRC.
This protects the most basic right to have private property, and to be free of theft. Therefore racial discrimination is allowed, because having private property is a more basic right embedded in the Constitution, while racial issues were legislated only between 1860s to 1960s.
Let's face it, the russian hackers are as fierce in their war against USA, as the red commies of Stalin and Khruschev were. They want to ruin you. There is ample proof that russian hackers are controlled by Putin's Kremlin, US DoD contractor Secure Computing Inc. testified for that in court of law.
Ideally, the former Soviet Union should be purged and cut off from the net. Online crime would drop 2/3rd that very minute according to all statistics.

How can you use a computer for financial or other business purpose when you do not know what programming you are running or what that programming does?
The days of the Cowboy Programmer Rodeo need to come to and end. Computers should not be updated on the fly as they are now
all programming updates should be sent to the customers packaged ( such as with "zip" ) so they they can be deliberately installed using Setup.exe
Setup.exe should be the ONLY program allowed to be used to update the programming on a computer
all received packages of software updates should include digital signatures such as produced by PGP and these signatures should be verified automatically by setup.exe before any updating can begin
customers need to learn to PARTICIPATE in security. this means physically visiting a n agent for a Certificate Authority to present credentials and receive keys for Certificate Authorities which need to be required for setup.exe
perhaps setup.exe should only run with the computer system offline ( network disconnected or local log on )
But the Cowboy Programming Rodeo needs to come to an abrupt end

The report does not seem to square with what I consistently hear from banking industry insiders at security conferences. The number of incidents seems to be way too low.
This leads me to draw one of three conclusions:
a) Most of the online attacks are for less than $5,000.
b) There is under reporting occurring.
c) The fraud type classification misrepresents the actual fraud source (e.g., keystroke logger used to steal credit card info and that is reported as credit card fraud instead of computer fraud.)
Someone from a major bank want to anonymously clear this up? PLEASE!

@JK- Obviously, I don't know for sure, but I'd say it's likely that all three of your explanations could be true, not just one.

When the financial industry starts to focus on user security and not user authentication, solutions will being to emerge and they will probably not involve browser technology as we know it. It's clear that browsers were never designed for secure online banking and all the 2-factor authentication in the world won't change that.
Here's a very simple analogy that demonstrates how authentication is not security. Our country's physical borders have legal points of entry that require authentication. If you have the right credentials, they let you in. However, if you want to enter illegally, all you need to do is go down the road about 50 miles and walk across an un-secured point. Now, would anyone argue that improving the security of a border crossing points in Texas stop people from illegally entering the country elsewhere in that state? Surely not. Web browsers are similar to the southern border of the US in that they can support authentication but do not provide border security. The criminals understand this concept and leverage the openness of browser design in their well-crafted malware (that by the latest numbers posted by federal scientists, evades more than 60% of AV software).
Today's malware writers have pushed our weak model to its limits and we should thank them for showing us the blunder we all made in assuming we had a free ride with the browser. Banks should look for a better model and leave browsers to serving us up news and entertainment. They're great for that because nobody gets hurt!

While the efforts are new and not yet fully integrated, suppliers are begining to address the issue of protecting the customer from himself. An example of this is this type of offer from Panda Security "Panda Security for Internet Transactions - http://www.pandasecurity.com/usa/about/corporate-news/new-42.htm". These system must get better and integrate tighter into the back-end systems for credential deactivation, but it is a start.
For example, this particular solution does not do anything notable for Phishing or man-in-the-middle senarios.
