Install Your Bank or Credit Card App to Avoid Fraudulent SMS Alerts
When your bank thinks there is something wrong with your account, it will call or text you. These communication methods are suitable for phishing attacks. Your bank’s smartphone app will protect you from these risks.
Krebs on Security explains how a local hotel’s phone systems were hacked through the SMiShing (SMS phishing) scam . Since the phone number was local, the victims called it more often. He suggests using your bank’s smartphone app to alert you of problems with your account.
It depends on the company, but many credit card apps in particular have alerts built in. When you receive this phone call or SMS with a jailbreak, check your app to see if there is an alert. Less likely to be compromised by hackers.
