Our debit card service provider, SHAZAM, has seen an increase in vishing fraud reports over the last 24 hours. Multiple reports have been from cardholders receiving automated and live telephone calls demanding account information. In at least one case, a message was left on a cardholder’s telephone, asking the cardholder to call back a toll-free telephone number to enter account information.
Unlike previous vishing attacks that follow a single source point or method of operation, these reports have varied widely. Some calls have referenced “Visa® debit” or MasterCard® debit”; some have referenced “your SHAZAM debit card”; and others have made no reference to an organization. Again, some have included recorded messages while others have had a live operator or callback option. One trend SHAZAM has noticed is some calls listing a “spoofed” caller identification number of 1402.
These calls are fraudulent and have not been authorized by SHAZAM or Iowa State Bank. Always remember, your bank will not ask for personal financial information that they already know about you. If you have questions, contact your local Iowa State Bank office immediately, or call 800.ISB.3595.
