Mango Markets

Hacked

DeFi · $MNGO · born 2021 · ✝ 2022

$115M drained by an oracle pump the attacker called 'legal'.

Mango Markets was a Solana DeFi trading protocol. In October 2022 Avraham Eisenberg manipulated the price of MNGO to inflate his collateral, then borrowed against it to drain ~$115M, later calling it a 'highly profitable trading strategy.'

Peak: ~$115M drained
Cause: Hacked
Year of death: 2022

☠️ Cause of death

The protocol valued collateral using a thin, manipulable spot oracle. Eisenberg pumped MNGO across venues, borrowed everything else against the inflated balance, and emptied the treasury in minutes.

📓 Lessons left behind

—Thinly-traded collateral is a price-oracle attack waiting to happen.
—'It was just trading' is not a defense the law accepts forever.
—Governance returning part of stolen funds doesn't undo the design flaw.

🌱 The idea that survived

Manipulation-resistant oracles

DeFi lending moved to deeper, time-weighted, multi-source oracles and stricter collateral listing after the Mango exploit.
