According to the Solana Eco-DeFi Agreement, DeFiTuna, the attackers used its lending pool leak to transfer approximately $580,000 in assets and left the USDC lending pool with an equivalent gap. At the time of the incident, Solana DeFi had recently experienced a series of security incidents, with ecological stress on the chain.

Gap in DeFiTuna loan pool

DefiTuna states that the attack directly affected its lending pool, which showed a gap of comparable value to the stolen money. No further technical details were disclosed in the article and the related investigation is still ongoing.

Before the incident, Drift Protocol had been attacked by some $285 million on 1 April. The report mentions that since then, the total value of the Solana network lock has been lost to nearly $1.5 billion.

There were 10 hacks in July.

According to DefiLlama tracking data, the cumulative losses from hacker attacks in the encryption industry exceeded $16.7 billion, with 10 security incidents recorded since July alone and the frequency of attacks remaining high.

Of these, the Arbitrum Eco-Renewal Contract Exchange Ostium was attacked on 15 July, at a loss of approximately $23 million. The chain data show that the attackers subsequently converted the stolen assets to approximately 12,085 ETH.

207 attacks in the first half of the year.

TRM Labs published a report in early July that showed a total of 207 encrypted attacks in the first half of 2026, reaching a new high. However, the total loss during the same period was $972 million, down from $2.3 billion in the first half of 2025.

The report states that the smart contract gap is the most common source of attack and that the damage to infrastructure is greater. The Democratic People ' s Republic of Korea-related attacks against Drift Protocol and KelpDAO resulted in a total loss of approximately $577 million.

AI exacerbates security concerns

According to the security company Certora, 15 previously unidentified issues were identified in the Solana Stark Pool audit and 11 mathematical security constraints were established. The team stated that the key issues had been repaired.

At the same time, Manuel Aráoz, a co-founder of OpenZeppelin, recently stated that as the AI tool is better at detecting code defects, the risk of leakage and exploitation of the DeFi protocol could increase further.
