Last July, we spoke with Jane Larimer, executive vice president of ACH network administration and general counsel for NACHA, about fraud in the ACH network via corporate account takeovers. In the latest interview in our Payments Spotlight podcast series, we revisit the issue of corporate account takeovers—this time, from a bank's point of view. Tina Giorgio, senior vice president of operations for Sandy Spring Bank in Columbia, Md., and a member of the Atlanta Fed's Retail Payments Risk Forum's Advisory Group, offered some helpful tips for financial institutions on how to best deter corporate account takeover attacks. The podcast is one that financial institutions would benefit from hearing and one worth sharing with their corporate customers.
Addressing corporate account takeover threats
NACHA's Risk Management Advisory Group (RMAG) published a newsletter in April 2010 detailing how criminals target institutions and what institutions can do to prevent an attack. Tina told us that the RMAG has been actively engaged in addressing corporate account takeovers since they emerged in 2007.
Additionally, Tina said that NACHA's board of directors released a policy statement in October 2010 stressing the importance of implementing sound business practices to mitigate the risk of corporate account takeovers in the ACH network. The RMAG, Tina tells us, is currently working on developing resources to assist businesses and banks alike in assessing, establishing, and strengthening sound business practices.
Taking the first step in the fight against corporate account takeovers
The banking system has been combating large-scale phishing attacks for some time now. In recent years, we've seen more frequent reports of global cybercriminals' successfully stealing the credentials of bank customers through numerous low-value transactions or one-time, large-scale attacks against corporate bank accounts.
Tina said that from a bank's perspective, the first step in detecting and protecting against corporate account takeovers requires diligent risk management from the institution and its corporate customer. Educating business customers about sound and safe business practices is critical; essential educational components include the importance of daily account reconciliation and deployment of up-to-date security patches.
Using the bank's existing tool kit
Cybercriminals use sophisticated commercial online banking malware to attack computers that store sensitive banking credentials. Some of these malicious software programs are reportedly undetectable and capable of defeating multi-factor authentication systems. Tina said she believes that some of the best tools at a bank's disposal for combating these malwares include employing out-of-band authentication and alerts, as well as maintaining the payment file initiation under dual control. She also said that banks may also already have in place some low-tech tools to help prevent these takeovers—exposure limits, origination calendars, and prenotifications all provide added security layers.
Ultimately, Tina said, banks and their corporate customers must remain vigilant in protecting against corporate account takeovers. Otherwise, their risk for these takeovers increases exponentially, and it is each of their responsibilities to act safely and defend against these types of cyberattacks. Fraudsters' attacks will continue to become more sophisticated, but adopting these tips and measures can best prepare banks and its corporate consumers to defend against cyber attacks.
