Security at a Glance πŸ‘€

Radiant: $58M

On October 16th, Radiant Capital suffered a security breach on Arbitrum and BSC, resulting in losses exceeding $50M. While the complete technical details of the exploit remain undisclosed, the protocol team confirmed the compromise of several developer wallets as the attack vector.

Unknown: $1.4M

On October 24th, an unknown Compound-fork protocol was exploited on Base, resulting in a loss of approximately $1.4m. While the affected contracts were unverified at the time of the incident, our analysis indicates that this attack was probably due to vulnerable price dependency on Uniswap spot price.

EGA: $554K

On October 5th, an unverified contract was exploited on BSC, causing a loss of $554k. The root cause was the lack of slippage protection in the function that buys EGA tokens from Pancake pairs, susceptible to price manipulation attacks.

P719: $315K

On October 11th, P719 token was exploited on BSC, resulting in a loss of $315k. While the compromised contract was unverified, we suspect the root cause was a flawed token burn mechanism within the P719 trading functionality.

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).
