Cyber Crime In The Banking Industry

Cyber Crime In The Banking Industry


Conducting business on the internet has become commonplace in recent years.  As a part of this evolution in commerce, banks and other financial institutions now offer virtual versions of their traditional financial services.  In addition to increased convenience and efficiency, the increased use of the internet has created vulnerabilities for banks and their customers for virtual theft and fraud.  Although virtual crime was unforeseen many years ago, the law has and continues to develop the rules for determining who liable for financial losses suffered from virtual crime, the banks or their account holders.  Like the internet, the answer can be complicated.

Liability for Hacked Consumer Accounts

Unlike the law applicable to commercial accounts, the Electronic Funds Transfer Act has created a relatively straightforward scheme for determining liability for cyber crimes against consumer accounts.  The Act imposes almost automatic liability on banks for cyber or electronic crimes against consumer accounts by limiting losses to consumers who comply with the requirements of the Act.  If, however, the consumer does not comply with the requirements of the Act, the customer alone will suffer the losses resulting from the crime.  The Act also limits the extent of bank liability to very low levels by requiring consumer victims to notify banks of the cyber or electronic crime within short time frames, which reporting enables banks to limit substantial losses by identifying and preventing repeated attacks against a hacked account.

Liability for Hacked Commercial Accounts

Commercial financial accounts are governed by Article 4A of the Uniform Commercial Code (“UCC”), which allows banks to avoid financial liability for cyber crimes if they employ “commercially reasonable” security procedures.  In addition to Article 4A, courts and the Federal Financial Institutions Examination Council (“FFIEC”) have established guidelines for determining whether a bank’s security procedures are “commercially reasonable.”

Generally, the determination of whether security procedures are commercially reasonable considers (1) the customer’s requests to the bank; (2) the particular characteristics of the customer known to the bank, including size, type of business, and frequency of banking activities; (3) available alternative security procedures; and (4) security procedures in general use by similarly situated customers and financial institutions. 

The FFIEC issued specific guidelines for electronic banking that also have an impact on the determination of whether certain security procedures are commercially reasonable.  The guidelines strongly encourage banks to utilize multilevel authentication methodologies that involve each of the following: (1) something the account holder knows (e.g., a password or PIN); (2) something the account holder has (e.g., an ATM card); and (3) something the account holder physically is (e.g., a fingerprint).  The FFIEC also instructs financial institutions to regularly monitor accounts and proactively report irregular activities by implementing “layered security programs” that detect and respond to suspicious activity.

In addition to limiting liability by following these guidelines, banks have avoided liability for cyber crimes against commercial accounts where, despite the availability of more comprehensive and secure procedures, the account holder chose less effective security procedures.  In circumstances such as that, the courts have determined that customers that chose to take on higher risk (often in exchange for less expensive and less cumbersome security procedures) may not shift a cyber crime loss to their banks.

However, banks have also been found liable for losses stemming from cyber crime despite having commercially reasonable security procedures in place.  Liability in these circumstances is typically imposed when banks fail to actively utilize their security procedures or act in good faith.  For instance, a bank that implemented security procedures beyond those encouraged by the FFIEC was held liable for cyber crime losses, because it failed to monitor and notify its customer of numerous transactions that were given “high risk scores” by its own security mechanisms, which high risk transactions turned out to be the fraudulent work of a hacker.  In another instance, a bank was found liable for hacking losses because of its authorization of numerous transactions over a short period of time that were out of character for the customer’s typically infrequent banking activities and resulted in the account going overdrawn $5 million.

Lessons Learned

As commerce continues to be conducted more regularly on the internet, cyber criminals will continue to create new ways to virtually steal real money from banks and their customers.  Accordingly, it goes without saying that financial institutions must stay informed and on the cutting of edge of cyber security to protect themselves and their account holders from cyber criminals.

In the context of consumer accounts, banks must be ready, receptive, and prepared to react to customer reports of cyber crime or fraud.  In this way only, can banks limit customer losses and their share of such losses imposed by the Electronic Funds Transfer Act.

Regarding commercial accounts, banks can control their exposure for cyber crime losses by implementing and continuously updating strong, multilayered security procedures, knowing the banking practices of their customers, proactively monitoring accounts for suspicious activity, and keeping their commercial account holders informed of any suspicious activity.
