So what should you do if your financial institution members are being bombarded with fraudulent text messages that ask them to call a specific number that in turn tries to phish credit card numbers or other sensitive information from them? A vulnerability assessment won’t help you here but you should keep the abuse numbers below handy.
You should email the abuse numbers for the carrier of that number . For example if you can find out that it was Verizon phone number, you can email Verizon at firstname.lastname@example.org and email@example.com. In addition you will want to forward the email to firstname.lastname@example.org and email@example.com as well.
So what information should you include in this email? You will want to include the following information:
Offending Text Message Number along with Area Code
The Victim Text Message Number along with Area Code
The Location the Text Message is calling From
The Calling Area
The Time Zone
The Time at the Current Location
You will also want to call the carrier of the offending number and attempt to have it blocked by the carrier. In most instances the carrier will be happy to do it for you.
