Yes, the address is correct. I received 111 ETH from Bitcasino.io. I managed to transfer 28 ETH to a contract address (Kraken), and then the remaining 88 ETH was maliciously taken. The involvement of a smart contract is indeed peculiar, and if anyone has insights into this, I'd be grateful to hear them.
I am truly sorry for your loss but this whole thing is very strange to me.
You said that there was about $7k at that address earlier, but that the "hacker" (or whatever is behind it) did not touch that money, but was waiting for a larger amount. When that larger amount has arrived, he hesitates and allows you to transfer a solid part of that money (about 1/3) and only after that, he transfers the rest of the ETH.
This really doesn't look like a serious hacker to me, To me, this really doesn't look like a serious hacker, it's just that he would leave the possibility of saving $50-$60k.
Certainly, the scenario you described is indeed puzzling. I agree that if a malicious actor had gained control of my private key or seed phrase, we would expect them to act more opportunistically. The presence of 12 Ethereum (~$35K as of my case) sat in my wallet untouched for almost 18 hours, I was withdrawing from that amount so it is highly unusual if a hacker had control over my wallet that they wouldn't touch those funds.
The sequence of events is indeed perplexing. The malicious activity started almost synchronously with the deposit of the larger sum of 111 Ethereum that I won from Bitcasino. Within minutes of this deposit, I successfully managed to transfer 26 Ethereum to my Kraken account. Only after this transaction, the unauthorized transfer of the remaining funds began.
The hacker's hesitation and the delayed reaction seem counterintuitive if we're dealing with a classic case of private key compromise. It doesn't make sense why they left a significant amount untouched in the wallet for so long, and why they waited until after a large deposit and a subsequent withdrawal by me before they moved the funds.
One potential explanation is a triggered event or condition - possibly a smart contract interaction or some other automated mechanism that was set to activate upon the receipt of a large deposit. I mentioned in my previous responses about a smart contract transaction that occurred immediately after the 111 Ethereum deposit. While the connection is uncertain, it's a point of interest that could potentially explain the odd timing.
Of course, these are all speculations based on the peculiar circumstances surrounding this incident. The reality may be different, and a thorough investigation is underway to get to the bottom of it.
It's indeed a perplexing situation, and I appreciate your interest in understanding this unusual case. I'll continue to update as I make progress with my investigations and hopefully provide some clarity in due time.
It's literally driving me crazy.
