For individuals who received a letter, this means that your sensitive personal information, which you entrusted to Citibank, may have been accessed by unauthorized parties. While the specifics of the compromised data are still under investigation, any exposure of information from a financial institution can lead to serious risks, including potential identity theft and financial fraud.

The most important step you can take right now is to carefully review the notification letter from Citibank N.A.
