Beware! How Criminals Exploit USSD

Publication Date: 01/12/2025

USSD codes are convenient — but they can also be exploited by criminals to access your banking information or hijack your mobile number. Stay informed and stay secure.

Common USSD Fraud Tactics

  1. 1. SIM Swap Fraud
    Criminals swap your number onto their own SIM card and then access mobile banking via USSD.
  2. Fake USSD Codes / Phishing Menus
    Fraudsters create fake USSD menus that mimic real services to steal your personal or banking information.
  3. Social Engineering Attacks
    You may be tricked into dialing certain USSD codes that secretly collect sensitive data.
  4. Man-in-the-Middle Attacks
    Because USSD is unencrypted, attackers can intercept sessions and capture your information.

How to Stay Safe

  • Only dial USSD codes from trusted, official sources.
  • Never share OTPs or PINs over USSD or during a phone call.
  • Report suspicious codes or messages to your bank or mobile provider immediately.
  • Enable and use SIM-lock PINs and alert your provider if you notice unusual SIM activity.
