According to Decrypt, a study analyzing blockchain data found that flash loan attacks resulted in the loss of more than $1.2 billion from decentralized finance (DeFi) protocols between 2020 and 2024. Researchers examined over 20 billion transactions to identify instances where flash loans were used in malicious or exploitative ways.
The study notes that attacks became increasingly sophisticated and less predictable throughout the five‑year period. No specific figures for individual incidents, timelines of each attack, or details of the exploited contracts are provided.
These findings highlight ongoing challenges for DeFi platforms in mitigating rapid, high‑value loan‑based exploits and suggest continued need for improved validation and monitoring mechanisms.
