Tiiwee X1 Alarm System Flaw: Your Burglar Alarm’s Secretly a Welcome Mat!
The Tiiwee X1 Alarm System has an “open door” policy for security breaches! Thanks to a vulnerability, all it takes is a radio signal capture and a Flipper Zero to disarm the system. Talk about an alarm system that doesn’t quite make a sound when it should.

Hot Take:
Who knew that a security system could actually be an open invitation for burglars? The Tiiwee X1 Alarm System might as well come with a “Welcome, thieves!” mat. It seems like this alarm system is more about giving the illusion of security than actually providing it. So, if your idea of home defense involves replaying the same scene over and over again, this is the system for you! Otherwise, you might want to look for something a bit more… secure.
Key Points:
- The Tiiwee X1 Alarm System is vulnerable to capture-replay attacks due to lack of encryption.
- The system communicates over 433 MHz radio signals which can be intercepted.
- Using a device like Flipper Zero, signals can be captured and replayed to disarm the system.
- The vulnerability was publicly disclosed on May 12, 2025.
- No solution has been provided yet, and the manufacturer’s response is still awaited.
