Code Auditing
August 9, 2021

Our system has observed a couple of transactions that have called “collectFees(0,0)” of the SorbettoFragola contract. Some of them are the copycats who want to launch the similar attack of (0xcd7dae143a4c0223349c16237ce4cd7696b1638d116a72755231ede872ab70fc). Fortunately, there are only limited number of tokens in the pool.

Newsletter - July 2026

July 2026's three largest DeFi incidents totaled approximately $67.9M in losses across Arbitrum and Solana. AFX Trade lost ~$24.15M after a supply chain attack compromised validator signing authority. Ostium's OLP vault was drained of ~$23.75M through compromised oracle infrastructure that submitted attacker-controlled prices. BonkDAO lost ~$20M when an attacker spent $4.4M to acquire enough voting power to pass a malicious treasury transfer with no timelock. All three incidents demonstrate that a protocol's security boundary extends far beyond smart contract code.

~$39.5M Lost: Allbridge, Wanchain & More | BlockSec Weekly

During the week of July 20-26, 2026, 8 notable security incidents resulted in approximately $39.5M in total losses across Solana, Ethereum, BNB Chain, Arbitrum, Zilliqa, and Cardano. The highlighted Allbridge Core incident (~$1.65M) exposed a Solana input validation flaw where the same Pool account was accepted in both swap roles, with analysis reconstructed entirely from the deployed program binary. Other analyzed incidents include Wanchain (~$500K, flawed message encoding in a Cardano bridge validator), Zilliqa (~$400K, flawed nonce generation in a Ledger app since 2019), and Lien Finance (~$542K, flawed validation logic in bond exchange).

~$1.35M Lost: BarnBridge, DeFiTuna | BlockSec Weekly

This weekly report covers 2 security incidents from July 13 to July 19, 2026, with approximately $1.35M in total losses on Ethereum and Solana. DeFiTuna, a Solana lending protocol, lost ~$570K because the position health check treated a zero-value position as healthy regardless of outstanding debt; the attacker used controlled swap routing and a separate low-liquidity pool to trigger this defect. BarnBridge lost ~$776K after an attacker exploited the protocol's deprecated but still-active governance system on Ethereum to pass a malicious proposal and drain user-approved USDC.
