Binance hack: the "$5M mistake" went to bots.
The story going around: the attacker sold 908,793 PROM, about $5M on paper, into a nearly empty Uniswap V2 pool and got 0.0316 ETH, about $71. That part is true.
What it leaves out: the PROM did not vanish. The attacker's sale was the first transaction in block 26310356 on Oct 31 at 04:28:47 UTC. The next five transactions in that same block were bots. Together they took 908,757 PROM out of the pool and sold it on.
So the attacker lost the PROM, and bots had it within the same 12-second block.
Check it yourself: block 26310356, the sale and the five transactions after it.
