SMS bombing, also known as SMS flooding, involves sending a large volume of SMS messages to a target phone number or system in a short period. This can cause significant harm to both users and businesses.
Harms to Users:
- Inconvenience and Disturbance: Users may receive hundreds or thousands of unwanted messages, making it difficult to access legitimate communications.
- Phone Malfunction: Excessive messages can overwhelm the phone's messaging app, causing slowdowns, crashes, or temporary unresponsiveness.
- Data and Battery Drain: Processing a flood of messages consumes mobile data and battery power, reducing device efficiency.
- Security Risks: Some SMS bombs may include phishing links or malicious content, leading to scams or malware infections.
Harms to Businesses:
- Service Disruption: SMS bombing can overload a business's messaging gateway, preventing legitimate customers from receiving important notifications (e.g., OTPs, alerts).
- Reputation Damage: Customers may associate the business with poor service if they experience delays or failures in receiving SMS due to bombing attacks.
- Financial Loss: Businesses may incur extra costs from increased SMS traffic or need to invest in anti-SMS-bombing solutions.
- Compliance Issues: If critical communications (e.g., banking alerts) are blocked, businesses may face regulatory penalties for failing to deliver essential services.
Example: A user receives 10,000 SMS messages in an hour, making their phone unusable. A business's customer support system is flooded with SMS requests, causing delays in delivering OTPs and frustrating users.
To mitigate SMS bombing, businesses can use Tencent Cloud's SMS Protection Service, which includes rate limiting, IP filtering, and AI-based anomaly detection to block malicious traffic while ensuring legitimate messages reach users.
