Oftentimes, you'll receive an email that says to call a number. It can be for anything—refunds, ask questions, etc.
Sometimes, this can be legitimate.
Other times, it's not.
How do you know?
Take a look at this attack that Avanan stopped:
This email wants you to see what looks like it could be an unwanted charge, call the number and potentially hand over financial information.
How do you know, though, that the phone number associated is not legit?
You have a few options. You can search the number, try to figure out where it's coming from. You could call the number and hope for the best.
Or, you could let Avanan do the work for you. Here's how we caught it and prevented it from reaching the inbox. The social graph saw a low reputation sender score, a red flag for an email containing financial information. Our AI was able to suss out that the email was financial in nature. Even though the email had no links, Avanan analyzed the email text and noted that the 844 toll-free number is typically associated with financial scams.
