DeFiYield REKT list reveals 18% decrease in lost DeFi funds during September totaling $170M

Defi YieldDeFi investment and yield farming platform tracks exploited projects across the DeFi ecosystem through its REKT database. Since January 2022, he has tracked over $60 billion in lost or stolen funds at his 1,195 events, including Terra Luna. Ronin, Nomad, Wormhole Bridge.

Approximately $2.4 billion was recovered during the same period, representing just under 5% of total losses. Until August, the majority of exploits occurred outside of his Ethereum ecosystem. However, since the beginning of August, over 90% of his lost funds have occurred within the Ethereum network, as shown in the chart below.

August saw a staggering loss of $212,927,092, of which the Nomad Bridge exploit accounted for $190 million. Other exploits included the Solana Slope wallet incident, ZBExchange, Reaper Farm, and Acala Swap. August’s most prominent exit scam totaled $3.5 million from Dragoma. There were also some high-value ragpulls from two of his NFT platforms, HeroCat and SudoRare.

Stolen or lost funds dropped 18% in September, while $170 million was withdrawn from the DeFi ecosystem through exploits and hacks. Wintermute’s hack accounts for the bulk of his $160 million in lost funding. Another $977,550 was lost to the same profanity vanity address exploit which DefiYield categorized as an “access control” issue.

Unlike other exploits such as the Boy X Highspeed exploit which took advantage of the project’s smart contract issue, the Wintermute/Profanity exploit was due to poor account management.

Wintermute used a flawed tool to generate vanity Ethereum addresses with compromised cryptographic security, prioritizing gas price optimization over security. The Boy x Highspeed exploit was the second largest in September at $2,584,890.

So far in October, we lost an average of $5.9 million per day within a week. If the trend continues, October will break the downtrend.

October’s largest exploit was the transit swap smart contract hack, which reached $29 million. But with $18.9 million already collected, DeFi’s net loss in October was just $10.1 million.
