While dumping stolen altcoins, the hacker appears to have made a very costly mistake.
The attacker sold 908,793 $PROM , worth approximately $5 million, into a nearly empty Uniswap V2 liquidity pool.
But instead of receiving millions, the swap returned just 0.0316 $ETH --- worth around $71. Yes, nearly $5M worth of PROM went in, and only $71 worth of ETH came out😳.

0x38546f9087ba0eb8444965711eb64a89fe9f53e80cd6d416317c847308219164

One swap. Nearly $5M in value wiped out.
