Your mobile can be made a target of SMS bombing. It means it receives in a short span a large number of messages so as to harass you and disrupt the functioning of your phone.

This could be done by using freeware and the downloaded apk files. Some of these SMS bombing applications are SMSBomber, TXTBlast and BombItUp. In majority of cases, the vulnerable API points are exploited by the websites to send either OTPs or text messages to legitimate users. The attackers exploit the APIs by making GET/POST requests with their scripts. It automates the process of sending SMSs.

The SMS bomber tool is easy to use. It requires the cell number and value, as to how many times the message will be repeated. On submission, the process starts and on completing the task gives the success alert.

Bombarding despite the DND is actually an offence and invades the privacy of a person.

The websites which provides SMS bombing tools also provides options to protect the cell phone number. If the number is enlisted on the protection list, SMS bombing cannot be made on it. There are anti-sms bombers also which block messages from a particular sender if the message is sent more than three times. Users can contact the security teams of the companies from whom such messages are received. The firm then can patch up vulnerable API.
