  • Publication number: 20250077717
    Abstract: A radio frequency (RF) tamper detector of an electronic device can offer improved chassis intrusion monitoring to protect the device from software and hardware-based tampering. The tamper detector can monitor RF noise levels in a first frequency band and in a second frequency band to calculate an RF noise level moving average for each frequency band. If the moving averages in both frequency bands exceed a RF noise threshold, the tamper detector can set a cover removal flag to indicate that a cover of the device housing has been removed. The tamper detector can cause the electronic device to lock or disable a system BIOS when cover removal is detected. Additionally, the electronic device can notify remote monitoring systems (e.g., operated by an IT administrator or warranty support center) to receive additional instructions to secure the device.
