Confused and need a clue

Back in January, I stupidly tried to ship some BNB to coinbase from Binance.us. I faithfully copied the coinbase tackle, verified it twice within the Binance withdrawal fields, and clicked ship. You all know what occurred subsequent, the funds by no means arrived and have been now stuck in limbo within the newly minted pockets on the BEP-20 network. I gnashed by tooth, rended my hair, and wept over my loss and then moved on. I additionally saved the handle in my bscscan.com account to forlornly view the stability every now and then and rub extra salt into my wound.

Quick ahead to yesterday once I acquired a discover that the tackle had transferred the funds to another tackle. I scratched my head and questioned, how? Don't new addresses created by such a mistake usually lose the keys to the enormous key pile within the void and make them inaccessible to all who come after?

Viewing bscscan, the brand new tackle from the unique transaction acquired the funds from a Binance 5 tackle. The new transaction transferred the funds to another Binance 5 handle.

Binance denied a restoration request. Binance help claims they haven't any management over addresses corresponding to these routinely generated lifeless end addreses. I get all of that. But it is just very odd that abruptly, this tackle (which did not exist earlier than my initial withdrawal as far as I can tell) transferred funds out.

Unique withdrawal txid: 0xb8a1c7b7eef5c18fa9e1488daf41c7e9654c7b7f48bce6d061ce71ba8065c232
Flawed chain handle: 0x4c2c46F6473e403209bDF1BAE51972F27127D808

Yesterdays transfer txid: 0x504fabee2f7056cc2001118f00786cbe3c96d2cf43bc9a89d0fc208f28dbc474
sent to deal with: 0x5BA434B40Be6cfc7033BF8d4545320Fa609a4268

Did someone at Binance.us create a backdoor that generates keys to fallacious handle withdrawals from fools like me that then allows them to siphon these funds at a later date? It could't be a coinbase thing as a result of they don't (as far as I know) use the BEP-20 community, right?

Any clue to help me perceive the current movement of the BNB would help me sleep extra simply. I'm not a lot on the lookout for recovery but understanding extra about how it's potential to transfer out of a seemingly lifeless finish handle can be nice.

Thanks
