FDIC: 2011 FIS Breach Worse Than Reported

A 2011 hacker break-in at banking industry behemoth Fidelity National Information Services (FIS) was far more extensive and serious than the company disclosed in public reports, banking regulators warned FIS customers last month. The disclosure highlights a shocking lack of basic security protections throughout one of the nation’s largest financial services providers.

fisJacksonville, Fla. based FIS is one of the largest information processors for the banking industry today, handling a range of services from check and credit card processing to core banking functions for more than 14,000 financial institutions in over 100 countries.

The company came under heavy scrutiny from banking industry regulators in the first quarter of 2011, when hackers who had broken into its networks used that access to orchestrate a carefully-timed, multi-million dollar ATM heist. In that attack, the hackers raised or eliminated the daily withdrawal limits for 22 debit cards they’d obtained from FIS’s prepaid card network. The fraudsters then cloned the cards and distributed them to co-conspirators who used them to pull $13 million in cash from FIS via ATMs in several major cities across Europe, Russia and Ukraine.

FIS first publicly reported broad outlines of the breach in a May 3, 2011 filing with the Securities and Exchange Commission (SEC), stating that it had identified “7,170 prepaid accounts may have been at risk and that three individual cardholders’ non-public information may have been disclosed as a result of the unauthorized activities.” FIS told the SEC it worked with the impacted clients to take appropriate action, including blocking and reissuing cards for the affected accounts. “The Company has taken steps to further enhance security and continues to work with Federal law enforcement officials on this matter,” it declared in its filing.

FIS’s disclosure to investors cast the breach as limited in scope, saying the break-in was restricted to unauthorized activity at a portion of its network belonging to a small prepaid debit card provider that it acquired in 2007.  But bank examiners at the Federal Deposit Insurance Corp. (FDIC) who audited FIS’s operations in the months following the 2011 breach and again in October 2012 came to a very different conclusion: According to a report that the FDIC sent May 24, 2013 to hundreds of FIS’s customer banks and obtained by KrebsOnSecurity, the 2011 breach was much larger than previously reported.

“The initial findings have identified many additional servers exposed by the attackers; and many more instances of the malware exploits utilized in the network intrusions of 2011, which were never properly identified or assessed,”  the FDIC examiners wrote in a report from October 2012. “As a result, FIS management now recognizes that the security breach events of 2011 were not just a pre-paid card fraud event, as originally maintained, but rather are that of a broader network intrusion.”

Indeed, the FDIC’s examiners found that there was scarcely a portion of the FIS network that the hackers did not touch.

“From review of the previous investigation reports, along with other documentation provided by FIS, examiners and payment card industry experts identified over 2,000 touch points that indicated a broad exposure of internal FIS systems and client related data,” the report notes. “These systems include, but are not limited to, the The New York Currency Exchange ATM network, prime core application systems, and various Internet banking, ACH, and wire transfer systems. These touch points also indicated approximately 100 client financial institutions, which appear to have had sensitive data exposed by the attackers.”

In an emailed statement, FIS maintained that “no client of FIS suffered any monetary loss as a result of the incident, and stressed that the report is based upon a review that was completed in October 2012.

“Since that time, FIS has continued to strengthen its information security and risk position, including investments over two years of $100 million or more, as part of our goal to provide best-in-class information security and risk management to each of our 14,000-plus clients. We have openly and regularly communicated these initiatives, our progress and results to our clients and shareholders through meetings, monthly updates, quarterly public disclosures, Board materials, educational webinars, and more.”

WHAT DOES $100 MILLION BUY?

Nevertheless, investors may be less than pleased about how FIS is spending its security dollars. The FDIC found that even though FIS has hired a number of incident response firms and has spent more than $100 million responding to the 2011 breach, the company failed to enact some very basic security mechanisms. For example, the FDIC noted that FIS routinely uses blank or default passwords on numerous production systems and network devices, even though these were some of the same weaknesses that “contributed to the speed and ease with which attackers transgressed and exposed FIS systems during the 2011 network intrusion.”

“Many FIS systems remain configured with default passwords, no passwords, non-complex passwords, and non-expiring passwords,” the FDIC wrote. “Enterprise vulnerability scans in November 2012, noted over 10,000 instances of default passwords in use within the FIS environment.”

The bank auditors also found “a high number of unresolved network and application vulnerabilities remain throughout the enterprise.

“The Executive Summary Scan reports from November 2012 show 18,747 network vulnerabilities and over 291 application vulnerabilities as past due,” the report charges.

What’s more, investigators probing the breach at FIS may have been denied key clues about the source of the intrusion because FIS incident response personnel wiped many of the compromised systems and put them back on the network before the machines could be properly examined.

“Many systems were re-constituted and introduced back into the production environment before data preservation techniques were applied,” the report notes. “Additionally, poor forensic preservation techniques led to numerous servers being re-imaged before analysis was completed and significant logging data was inadvertently destroyed. Several servers, key to the investigation process, were re-introduced into the production environment and subsequently re-compromised due to misconfigured baselines and inadequate security testing outside of corporate policy.”

Big Bank Mules Target Small Bank Businesses

A $170,000 cyberheist last month against an Illinois nursing home provider starkly illustrates how large financial institutions are being leveraged to target security weaknesses at small to regional banks and credit unions.

I have written about more than 80 organizations that were victims of cyberheists, and a few recurring themes have emerged from nearly all of these breaches. First, a majority of the victim organizations banked at smaller institutions. Second, virtually all of the money mules — willing or unwitting individuals recruited to help launder the stolen funds — used accounts at the top five largest U.S. banks.

The attack on Niles Nursing Inc. provides a textbook example. On Monday, Dec. 17, 2012, computer crooks logged into the company’s online banking accounts using the controller’s credentials and tunneling their connection through his hacked PC. At the beginning of the heist, the miscreants added 11 money mules to Niles’ payroll, sending them automated clearing house (ACH) payments totaling more than $58,000, asking each mule to withdraw their transfers in cash and wire the money to individuals in Ukraine and Russia.

nilesmulespartNiles’ financial institution — Ft. Lauderdale, Fla. based Optimum Bank — evidently saw nothing suspicious about 11 new employees scattered across five states being added to its customer’s payroll overnight. From the bank’s perspective, the user submitting the payroll batch logged in to the account with the proper credentials and with the same PC that was typically used to administer the account. The thieves would put through another two fraudulent payment batches over next two days (the bank blocked the last batch on the 19th).

In total, the attackers appear to have recruited at least two dozen money mules to help haul the stolen loot. All but two of the mules used or opened accounts at four out of five of the nation’s top U.S. banks, including Bank of America, Chase, Citibank, and Wells Fargo. No doubt these institutions together account for a huge percentage of the retail banking accounts in America today, but interviews with mules recruited by this crime gang indicate that they were instructed to open accounts at these institutions if they did not already have them.

ANALYSIS

I’ve spoken at numerous financial industry conferences over the past three years to talk about these cyberheists, and one question I am almost always asked is, “Is it safer for businesses to bank at larger institutions?” This is a tricky question to answer because banking online remains a legally and financially risky affair for any business, regardless of which bank it uses. Businesses do not enjoy the same fraud protections as consumers; if a Trojan lets the bad guys siphon an organization’s online accounts, that victim organization is legally responsible for the loss. The financial institution may decide to reimburse the victim for some or all of the costs of the fraud, but that is entirely up to the bank.

What’s more, it is likely that fewer cyberheists involving customers of Top 5 banks ever see the light of day, principally because the larger banks are in a better financial position to assume responsibility for some or all of the loss (provided, of course, that the victim in return agrees not to sue the bank or disclose the breach publicly).

I prefer to answer the question as if I were a modern cyberthief in charge of selecting targets. The organized crooks behind these attacks blast out tens of millions of booby-trapped emails daily, and undoubtedly have thousands of stolen online banking credentials to use at any one time. There are more than 7,000 financial institutions in the United States…should I choose a target at one of the top 10 banks? These institutions hold a majority of the financial industry’s assets, and they’re accustomed to moving huge sums of money around each day.

On the other hand, their potential for fraud is almost certainly orders of magnitude greater than at smaller institutions. That would suggest that it may be easier for these larger institutions to justify antifraud expenditures. That incentive to enact antifraud protections is even greater because these institutions have huge numbers of retail customers, a channel in which they legally eat the loss from unauthorized account activity.

Fiserv to Banks: Stay on Outdated Adobe Reader

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.”
