How Do Payment Account Hijacks Happen?

Common Attack Methods

Attack Type	Method	Risk Level
SMS ফিশিং (Smishing)	Fake texts with malicious links	Very High
ফিশিং Sites	Fake login pages mimicking payment apps	High
SIM Swapping	Fraudulently porting your phone number	High
Credential Stuffing	Using leaked passwords from other breaches	Medium
Malicious Apps	Keylogger-infected apps capturing credentials	Medium

Real-World Scenarios

• A text claiming "suspicious activity" on your bKash account links to a fake login page that captures your credentials
• Hackers use your leaked email/password from another breach to access your payment app
• A scammer convinces your carrier to transfer your number to their SIM, intercepting your 2FA codes

7 Essential Security Steps to Take Right Now

1. Enable টু-ফ্যাক্টর অথেন্টিকেশন (2FA)

This is non-negotiable. Turn on 2FA in your payment app settings. Use an authenticator app (Google Authenticator, Authy) rather than SMS when possible — SMS-based 2FA is vulnerable to SIM swapping.

2. Set a Unique Payment PIN

Your payment PIN should be different from your phone unlock code and your app login password. Enable biometric অথেন্টিকেশন (fingerprint, Face ID) as an additional layer.

3. Use Unique Passwords

Never reuse passwords across services. Use a password manager like 1Password, Bitwarden, or Apple Keychain to generate and store unique passwords for every account.

4. Turn On Transaction Notifications

Enable push notifications for every transaction and login attempt. Immediate awareness of suspicious activity is your first line of defense.

5. Limit Linked Account Access

Set transfer limits on linked bank accounts. If your payment app is compromised, lower limits reduce potential losses.

6. Only Use Official Apps

Download payment apps exclusively from the Apple App Store or Google Play Store. Never install APKs from unknown sources or click on links in emails to "update your app."

7. Regularly Review Login Activity

Check your account's active sessions and login history periodically. Revoke access from any device you don't recognize.
