60-second summary
Flash loan attacks siphon $1.2 billion from DeFi protocols between 2020 and 2024, researchers report after scanning over 20 billion transactions. The study shows attackers increasingly use complex, unpredictable vectors, exploiting smart‑contract flaws and oracle manipulations. As exploit techniques evolve, DeFi platforms face heightened security pressures, prompting investors to demand stronger safeguards and potentially slowing capital inflows.
Attacks grew more sophisticated and less predictable over the period, according to researchers who scanned more than 20 billion transactions.
