Cosmos EVM Hacker Minted $50 Million - and Walked Away With Just $60,000
An attacker exploited a vulnerability in the Cosmos EVM to move $50 million of Nesa (NES) off the project's chain. However, the payout came to $60,000.
Blockchain analytics firm Bubblemaps traced the wallets involved. Liquidity vanished from the pools before the selling finished, and extreme slippage swallowed almost the entire position.
How the Nesa Exploit Unraveled
The main wallet, 0x9AE7, bought $250,000 of NES and bridged the tokens to Nesa Chain. Bubblemaps said the address was funded through Monero (XMR).
The attacker exploited the bug, inflating that balance by 200 times. He then bridged roughly $50 million of NES back to Ethereum (ETH).
From there, the tokens moved through eight addresses. Those wallets swapped NES for ETH on decentralized exchanges before routing proceeds to centralized platforms.
However, liquidity disappeared from the pools before most of the selling happened. The swaps hit extreme slippage, and the attacker recovered $315,000 against $255,000 spent.
