City Bank is aware of the newly discovered "Shellshock" bug which exploits a known vulnerability on various operating systems such as Unix, Linux, and Mac OS. After rigorous testing, we have not detected any breaches or compromises to our systems.  We are proactively complying with regulatory agency recommendations. City Bank is committed to providing customers with a secure banking environment. City Bank will continue to monitor the situation. As always, customers are urged to actively monitor their accounts—through text-alerts (using City Bank’s BnkNGo), and use of preventative behavior to keep sensitive information protected.
