D3dsecurity: >> Xz-G12 Firmware >> 2.1.17 Security Vulnerabilities
D3D Wi-Fi Home Security System ZX-G12 v2.1.1 is vulnerable to RF replay attacks on the 433 MHz sensor communication channel. The system does not implement rolling codes, message authentication, or anti-replay protection, allowing an attacker within RF range to record valid alarm/control frames and replay them to trigger false alarms.

D3D Wi-Fi Home Security System ZX-G12 v2.1.17 is susceptible to RF jamming on the 433 MHz alarm sensor channel. An attacker within RF range can transmit continuous interference to block sensor transmissions, resulting in missed alarms and loss of security monitoring. The device lacks jamming detection or mitigations, creating a denial-of-service condition that may lead to undetected intrusions or failure to trigger safety alerts.
