Phalcon 的黑客攻击阻断历程

April 23, 2024

自 BlockSec 于 2021 年首次亮相以来,我们一直认为代码审计本身无法解决所有 Web3 安全问题。因此,我们一直在投资探索 Web3 安全的新范式。为此,我们创建了 Phalcon,这是世界上第一个加密货币黑客阻止系统。

在 Phalcon 推出之前,该系统已在内部运行 2 年,成功阻止了 20 多起黑客攻击,并挽救了价值超过 2000 万美元的资产,其中包括为 Saddle Finance 挽救了 380 万美元,为 Platypus 挽救了 240 万美元,为 ParaSpace 挽救了 500 万美元,等等。

在本系列文章中,我们将展示我们系统 Phalcon 的代表性故事。通过分享这些案例,我们的目标不仅仅是验证我们系统的有效性。我们还希望展示主动防御措施的变革性影响。

面对威胁,我们并非无能为力。携手共进,我们可以迎来 Web3 安全的新时代。

~$15.9M Lost: Trusted Volumes & More | BlockSec Weekly

This BlockSec bi-weekly security report covers 11 notable attack incidents identified between April 27 and May 10, 2026, across Sui, Ethereum, BNB Chain, Base, Blast, and Berachain, with total estimated losses of approximately $15.9M. Three incidents are analyzed in detail: the highlighted $1.14M Aftermath Finance exploit on Sui, where a signed/unsigned semantic mismatch in the builder-fee validation allowed an attacker to inject a negative fee that was converted into positive collateral during settlement; the $5.87M Trusted Volumes RFQ authorization mismatch on Ethereum; and the $5.7M Wasabi Protocol infrastructure-to-contract-control compromise across multiple EVM chains.

Newsletter - April 2026

In April 2026, the DeFi ecosystem experienced three major security incidents. KelpDAO lost ~$290M due to an insecure 1-of-1 DVN bridge configuration exploited via RPC infrastructure compromise, Drift Protocol suffered ~$285M from a multisig governance takeover leveraging Solana's durable nonce mechanism, and Rhea Finance incurred ~$18.4M following a business logic flaw in its margin-trading module that allowed circular swap path manipulatio

~$7.04M Lost: GiddyDefi, Volo Vault & More | BlockSec Weekly

This BlockSec weekly security report covers eight attack incidents detected between April 20 and April 26, 2026, across Ethereum, Avalanche, Sui, Base, HyperLiquid, and MegaETH, with total estimated losses of approximately $7.04M. The highlighted incident is the $1.3M GiddyDefi exploit, where the attacker did not break any cryptography or use a flash loan but simply replayed an existing on-chain EIP-712 signature with the unsigned `aggregator` and `fromToken` fields swapped out for a malicious contract, demonstrating how partial signature coverage turns any historical signature into a generic permit. Other incidents include a $3.5M Volo Vault operator key compromise on Sui, a $1.5M Purrlend privileged-role takeover, a $413K SingularityFinance oracle misconfiguration, a $142.7K Scallop cross-pool index injection, a $72.35K Kipseli Router decimal mismatch, a $50.7K REVLoans (Juicebox) accounting pollution, and a $64K Custom Rebalancer arbitrary-call exploit.
