$7.5 Million Counterattack: When Ethereum’s Biggest Trap Snaps Itself


【Plain-Language Guide】On June 20, 2026, Ethereum’s top sandwich bot, jaredfromsubway.eth, saw its vault emptied in a single transaction worth $7.5 million. The hacker carefully laid the scheme using 66 fake token pools, exploiting its “floating approval” vulnerability. Previously, the hacker also seized $25.2 million by impersonating a 32 ETH validator and taking it from top MEV bots.
The predator turns into the prey, revealing a deep crisis in Ethereum transaction security under the MEV arms race: mempools becoming public, abuse of approvals, and the risk of validator cheating. Ordinary users are being harvested with an invisible “tax” on every transaction, making it urgent to switch to MEV-protection RPCs and revoke approvals regularly.
