Remember, blocking unknown senders is an important step in protecting yourself from spam and phishing attacks.
Avoid Text Replies
If you don't recognize the sender or the number, ignore instructions to respond to the text message. This is a common trick to verify that your number is active.
Scammers will send fake "opt-out" messages to encourage you to respond. Don't fall for it.
To prevent future texts, never text "STOP" if you don't recognize the sender. This is a common ploy to verify that your number is actively in use.
Never dial call-back numbers either, no matter how tempting it may be.

To confirm whether a message is a fake blocked message or not, look for responses that ask you to respect the recipient's decision or provide further information. These messages are often trying to distract you from the fact that you're being scammed.
Here are four ways to identify spam texts:
- They often contain urgent or threatening language.
- They may ask you to click on a link or provide sensitive information.
- They can be from unknown or unfamiliar numbers.
- They may contain spelling or grammar mistakes.
Check Who You
If you're not getting someone's messages, you can check if they're in your Blocked Contacts. A recipient can't find out if they're blocked.
To check your Blocked Contacts, go to Settings > Apps > Messages. Tap Blocked Contacts, then do any of the following:
- Check the list of blocked contacts.
- See if the person you're trying to reach is on the list.
You can also check your message history to see if the person's messages are being sent to your "Blocked Contacts" folder. If they are, it's likely that you've blocked them.
Still Getting SMS/OTP Bombs?
If you're still getting SMS/OTP bombs even after protecting your number, it might be because the person is using a script to access the OTP API of the company they're using for login.

In some cases, it may be difficult to find the culprit, but by reporting the issue to the relevant authorities, you can help prevent others from falling victim to this type of harassment.
Here are some steps you can take to protect yourself and report the issue:
- Contact your local cyber cell to report the incident
- Reach out to the company whose OTP API is being accessed and report the issue
- Consider adding a filter to your phone's messaging app to block unknown senders
By taking these steps, you can help prevent further harassment and protect yourself from SMS/OTP bombs.

Here are some common red flags to watch out for in fake blocked messages:
- Claims that your messages are being blocked by the recipient
- Says that the recipient has chosen to block your number
- Claims that they can't provide further information

SMS Bomb Technical Details
Companies often use their API to send One-Time Passwords (OTPs) for login and password reset purposes, but some may neglect to secure these APIs.
Many companies don't look into the security aspects of their APIs, which can be exploited by attackers.
These APIs can be accessed using GET/POST requests with scripts, resulting in an OTP SMS being sent to a user's number.
Some APIs may be unsecured, allowing anyone to access them by making a request to the API link.
For example, an unsecured API link may be used to send an OTP SMS to a user's number.
By exploiting these unsecured APIs, attackers can send OTP SMS to users' numbers, potentially leading to a SMS bomb.
