Worth noting, I had about $7k in my wallet all day, untouched. But as soon as the large deposit came in, it was swiped. Clearly, it was a targeted operation.
But there was another withdrawal on 26.8381 ETH, which you don't mention, which at that time was $50 thousand dollars. And this transaction was carried out 5 minutes earlier than the amount of 88ETH was stolen. Maybe someone saw how you made the first withdrawal from the wallet?
