Report Online Scams

Cyber criminals use the Internet to defraud consumers in a variety of clever ways. By simply performing an action such as opening an email attachment, accepting a fake friend request on a social networking site, or visiting a compromised,(e.g. infected) website you could be opening yourself and your on-line devices to cybercrime.

If you feel your on-line account or computer has been compromised, contact Comerica Bank®.
