SMS bombing, or SMS flooding, involves sending a large volume of SMS messages to a target number in a short time, often for harassment or denial-of-service purposes. Attackers use various tools to automate this process. Here are common types of SMS bombing tools and examples:
Online SMS Bombing Platforms
These are web-based services that allow users to input a target phone number and send multiple SMS messages automatically. Examples include websites like SMSBomber.me or similar platforms.
Mobile Apps
Some Android apps are designed to send bulk SMS messages to a target number. These apps often disguise themselves as prank tools but can be misused for SMS bombing.
Custom Scripts (Python, etc.)
Attackers may write scripts using programming languages like Python to send SMS messages via online SMS gateways or APIs. For example, a script could loop through an API call to send SMS repeatedly.
Botnets
In some cases, attackers use botnets (networks of compromised devices) to send SMS messages from multiple sources, making it harder to block the attack.
To mitigate SMS bombing, services like Tencent Cloud's SMS service provide rate limiting, CAPTCHA verification, and IP blocking to prevent abuse. Additionally, Tencent Cloud's anti-DDoS solutions can help protect against large-scale SMS flooding attacks.
