~$18M Lost: jaredFromSubway, Aztec & More | BlockSec Weekly
This weekly blockchain security report covers June 15 to June 21, 2026, with 3 notable incidents across Ethereum and BNB Chain totaling approximately $18.3M in losses. Two incidents are analyzed in detail. Based on on-chain analysis, the highlighted jaredFromSubway incident reveals a reversed approval attack pattern: unlike traditional exploits where attackers abuse vulnerabilities in trusted DeFi contracts to drain user-approved assets, this MEV bot proactively approved its own assets to untrusted third-party contracts for arbitrage. The attacker constructed fake wrapper tokens and swap pools that emitted real events but never consumed the granted allowances, with reported total losses of ~$15M. The report also covers Aztec's second exploit in three days, where a missing equality constraint between two witnesses for `old_data_root` in the escape hatch ZK circuit allowed the attacker to prove ownership of fabricated notes against a fake Merkle tree while passing on-chain root validation.

~$5.98M Lost: Aztec, Raydium & More | BlockSec Weekly
This weekly blockchain security report covers the period of June 8 to June 14, 2026, analyzing 4 notable incidents across Ethereum and Solana with total losses of approximately $5.98M. The highlighted events include Aztec Connect, where a missing input validation allowed the rollup's proof path and L1 settlement to reach inconsistent states, and Raydium, where a missing validation check on the legacy AMM v3 program allowed an attacker to manipulate the LP token redemption calculation and drain four pools. Both vulnerabilities had been live for years before exploitation. The report examines attack types including lack of input validation, integer overflow, and governance capture.
