The address appear when he lost his funds and was itself cleared one day later.
However, it also sees the transfer of over 1000 btc as if it was the staging area of a large scale attack.
Does anyone know what has happened there?
Thanks,

The attacker, after stealing the bitcoin, used a coin mixer service, so he could not be tracked.
Mixers are amazing for privacy, so you will never know where your coins are now. They were mixed with thousands of coins in many Transactions... It is lost now.
Did you buy your device from the official store? From third party? Was the firmware update?
Your device is compromised if it was bought from third party. If that's the case, just discard it.
