SMS Bombing Prevention

SMS bombing is the act of using malicious programs or tools to send a large number of unwanted SMS messages to one or more mobile numbers within a short period of time, thereby harassing users.

• Use the traffic threshold management function of Message & SMS. When the total number of SMSs sent exceeds the threshold you set, the platform automatically suspends SMS sending to reduce losses caused by SMS bombing.
• The system sets default alarm values and limit values. Change the values based on your service requirements. For details, see Settings.
• You can set limits on the frequency of SMS sending to each recipient number under the same application. For details, see Settings.

SMS bombing often involves verification code SMSs. Verification code requests are submitted repeatedly for one or more numbers in batches using malicious programs or tools.

Use CAPTCHA codes to prevent SMS bombing.
