Flash loans: borrow $500M with zero collateral, manipulate AMM spot price oracles, hijack governance votes in a single block, run MEV sandwich attacks via Flashbots bundles. The only cost is gas. Euler Finance lost $197M via a donated-reserve trick that manufactured fake insolvency and turned Euler's own liquidation engine against itself. https://www.kayssel.com/newsletter/issue-56/

@rsgbengi@infosec.exchange The fact that Euler's own liquidation engine became the exploit vector is a perfect example of how DeFi's composability cuts both ways - your safety net turns into a weapon the moment someone finds the seam. That's the kind of failure mode traditional finance doesn't even have to think about.

@rsgbengi@infosec.exchange You saw the Euler thing live or just read about it after?
