It’s finally Friday! Unfortunately, scammers don’t take weekends off. 📞
Fraudsters are getting better at sounding convincing and can even spoof phone numbers to make it appear your bank is calling. If you ever receive a call asking for sensitive information like your:
🔒 Online banking credentials
💳 Account or debit card information
🪪 Social Security number
📱 Security or verification codes
Pause before responding. 🛑
If something feels suspicious or just doesn’t seem right, hang up and call your bank directly before providing any information. A quick double-check can go a long way in helping keep your information secure.
