Hi Terence,

Could you please specify what you mean? Are you wondering about the security of Zigbee with nRF52840 DK, or do you want to know how to perform packet injection or replay attack? What's your goal?

Best regards,

Marte

Hi Terence,

Zigbee is considered a secure mesh network, and I'm not aware of any Zigbee attack, nor do I know how to perform one, so I can't tell you how to attack our Zigbee products with packet injection or replay attack.

However, if you're interested in the security part of Zigbee, you can read about that in the Zigbee specification, which is available for everyone. There you can read about encryption, layer counters, frame counters and more.

Best regards,

Marte
