According to Wikipedia, social engineering is the psychological manipulation of people into performing actions or divulging confidential information. Generally, social engineering is done through phone calls or the internet.
Social engineering is one of the methods used by hackers to get information on their targets by digging information directly to credit card users or other parties who have confidential data.
This social engineering method is usually effective when applied to a more senior credit card user.
The main goal of this crime is for hackers to get the OTP (one-time password) code you received through SMS and CVV numbers (3 last digits on the back of a credit card) of the user.
Scammers usually do their business through phone calls and claiming to be BCA’s employees or officials. These social engineering methods often happen to customers in such forms:
- Suspicious transaction reports. Scammers would call card users and tell them there are an incredible amount of suspicious transactions on their credit cards, and offer them help to cancel the transactions by giving CVV numbers and OTP codes as requirements.
- Raffle prize winner. Scammers usually call credit card users and tell them they are winning a BCA’s Credit Card raffle program, and ask for their CVV numbers and OTP codes for admin purposes.
- Card limit increases offers. Scammers would call and promise credit card users an increase in their credit card limit, as long as victims give their CVV numbers and OTP code.
