Is bank account hacking possible? How?

 The Answer is definitely yes !

The most the most common method for hacking bank accounts is phishing. Hackers will obtain the mail list of bank account holders from any vulnerable website by injecting via SQL vulnerability. With the help of web shells they can upload a Mailer and send mail from any emails even from google@gmail.com. On the other hands, they would create phishing website that would look exactly as the original website. The only thing that differs from the original website i URL and mostly the fake website will not have a SSL certificate i.e https.

I will show you an example. Let's assume that the attacker is planning to obtain the Paypal information of a victim. Using the mailer hosted on the any web shell, Attacker couldd spoof anh mail ID and send mail which will look exactly as official email from PayPal.

This is an example of spoof email from the attacker. And when you click on the link came in the email, you will be redirected to a phishing site where your information can be easily Hijacked by the attacker.

This is this is an example for Paypal phishing page. As you can see, the URL is only thing that differs from the original website and that is only thing which would help you figure out whether is original or not.

Similarly, Bank account can also be hacked just my knowing the mail ID of the victim
