Alert : Fraudulent SMS via “SMS Blaster”

Since late March 2025, a new form of smishing has been spreading worldwide: cybercriminals are using devices called SMS blasters to send massive amounts of scam messages. This type of fraud now targets many countries, including the UK, USA, Canada, Germany, and more. Stay alert—here’s how to spot it and protect yourself.

SMS Blaster Scam Alert

This scam uses a small transmitter (blaster) to create a fake mobile network (often on 2G). Phones nearby automatically connect and receive SMS messages impersonating banks, government agencies, or public services.

How it works

Fraudsters use a disguised mobile device to broadcast from a fake antenna. Phones connect automatically and receive an urgent message, such as “unpaid fees,” with a link to a phishing website. If you interact with the fake site, your banking details may be stolen. This technique enables mass SMS delivery without needing to target specific numbers.
Warning signs: message from an unknown or very short local number, alarming content urging immediate action, suspicious URLs, or strange website domains.

Tips to protect yourself:

• 📵 Disable 2G on your phone if possible (especially on Android)
• 🛡 Enable filtering of messages from unknown senders (iPhone and Android)
• 🔗 Never click on a link you receive unless you can confirm it—always contact the organization directly through their official channels
• 🚫 Never share sensitive information via SMS
• 📱 Forward suspicious messages to your provider’s SPAM service (e.g., 7726 in the UK/US)
• 🗣 Tell your friends and family, especially elderly or vulnerable people

Conclusion

If you receive an alarming SMS with a link or from an unknown number, do not click it—disable 2G or filter unknown contacts if you can. Report the message to your operator or official platforms and share this alert with your loved ones. To learn more and better protect yourself, read our internal guide.
