🚨 What Is SMS Bombing?
SMS bombing is a type of spam attack where a large number of text messages are sent to a single phone number within a short period. This is typically done using automated tools known as SMS bombers.
These tools exploit systems such as:
OTP (One-Time Password) services
Registration or login forms
Subscription APIs
The goal is to flood a user’s phone with messages, causing disruption or harassment.
⚙️ How SMS Bombers Work
SMS bombers automate repeated requests to services that send SMS messages. Here’s how:
Bots identify vulnerable websites or apps
Scripts repeatedly trigger OTP or verification requests
The system continuously sends SMS messages to the target number
Without proper safeguards, this can overwhelm both users and business systems.
⚠️ Risks of SMS Bombing
For Individuals:
Phone becomes unusable due to message flooding
Important calls or alerts may be missed
Increased stress or harassment
For Businesses:
Higher SMS costs due to abuse
Server and API overload
