A Review of Balancer's Security Incidents Over the Years: $21 Million Lost Due to Flash Loans, Front-End Hijacking, and Cross-Protocol Vulnerabilities
ChainCatcher reported that the DeFi protocol Balancer is currently under attack, with losses across multiple chains now exceeding $116.6 million. The attack on Balancer is still ongoing.
According to on-chain AI analysis tool CoinBob, the historical security incidents of Balancer are as follows: · June 2020 Flash Loan Attack: Attackers exploited compatibility issues between deflationary tokens (STA/STONK) and Balancer smart contracts, repeatedly calling swapExactAmountIn to drain liquidity pools, ultimately profiting $523,600. · August 2023 V2 Pool Vulnerability: Balancer V2 pools suffered multiple flash loan attacks due to code vulnerabilities, resulting in total losses of $2.1 million. The team urgently paused affected pools and advised users to withdraw funds, but some funds that were not withdrawn in time were still exploited. · September 2023 Frontend Hijacking Attack: Hackers used BGP/DNS hijacking to control the Balancer frontend, tricking users into authorizing malicious contracts, causing $238,000 in losses. On-chain investigator ZachXBT traced the funds to address 0x645710Af050E26bB96e295bdfB75B4a878088d7E. · 2023 Euler Incident Impact: Due to a vulnerability in Euler Finance, Balancer's bbeUSD pool lost $11.9 million, accounting for 65% of the pool's TVL. The team implemented protective measures to restrict liquidity withdrawals. · 2024 Velocore Attack Connection: The Velocore vulnerability exploitation involved Balancer-style CPMM pools, resulting in $6.8 million in losses. Balancer's technical architecture was indirectly implicated due to cross-protocol integration.

Deutsche Bank: After the three major central banks hiked rates simultaneously, the market may once again underestimate the terminal interest rate
Deutsche Bank points out that as central banks in the US, Europe, and Japan are tightening policy simultaneously, the market may still be underpricing the eventual terminal rates. With oil prices remaining high, inflation may spill over into core inflation and wages. Moreover, financial conditions have not tightened in tandem, which could weaken the effect of rate hikes. Citing the experience of 2022, Deutsche Bank notes that the market then expected a total of around 200 basis points of Fed rate hikes in the first year, but the final figure exceeded 400 basis points, illustrating that the market often underestimates the terminal rate.
