"Heartbleed" Bug

We are keeping a close eye on the "Heartbleed" bug you may have heard about. The vendor we use for Online Banking has completed a preliminary assessment and has not discovered any vulnerability. However, there are a number of ancillary services within your online banking experience that have not yet completed their assessment. We will be sure to keep you updated. Thank you, Commercial Bank.
