Citing the Radiant Capital and Bybit incidents as examples of the same attack pattern repeating, the piece proposes independent transaction verification through a second channel as a simple but underused fix, and lists five questions auditors should ask about infrastructure, signing processes, and incident response. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What attack vector was used in the Bybit hack that resulted in a $1.5 billion loss? Frontend poisoning combined with blind signing enabled the Bybit exploit. Signers saw one transaction displayed on their screen while their hardware wallets (Ledgers) actually signed a different, malicious transaction, allowing attackers to drain funds despite multi-sig protections being in place. _Anyone tracking DeFi exploit patterns can follow security postmortems like this on daily.dev._ ### How can a DeFi protocol protect against frontend poisoning attacks on multi-sig transactions? Independent verification through two separate channels can neutralize frontend poisoning. One channel is the standard signing interface (such as a Safe Wallet screen), which can be compromised, while a second independent tool reads the transaction directly from the blockchain and explains it in plain English, catching any discrepancy before signing. _Teams hardening multi-sig workflows can find practical security approaches like this on daily.dev._ ### Why did the Radiant Capital hack happen despite the protocol having passed security audits? Radiant Capital's entire infrastructure depended on a single developer's AWS session tokens, meaning that compromising one developer's cloud credentials was enough to bypass the protection multi-sig was supposed to provide. The 2024 breach, resulting in a $50 million loss, exploited this infrastructure weakness rather than a flaw in the smart contract code itself. _Developers weighing infrastructure risk alongside code audits can track similar incidents on daily.dev._ ## Similar posts on daily.dev - [The Current Position of AI in Web3 Sec: AI Mirage and the High Cost of “Cheap” Security](https://daily.dev/posts/the-current-position-of-ai-in-web3-sec-ai-mirage-and-the-high-cost-of-cheap-security-u9drwpfpu) · Coins Bench · 0 upvotes · 0 comments - [On-Chain Smart Contract Audits: Bringing Transparency and Verifiable Security to Web3](https://daily.dev/posts/on-chain-smart-contract-audits-bringing-transparency-and-verifiable-security-to-web3-msyokdob8) · Coins Bench · 2 upvotes · 0 comments - [No Visibility, No Trust: A Lesson for New Smart Contract Security Researchers](https://daily.dev/posts/no-visibility-no-trust-a-lesson-for-new-smart-contract-security-researchers-9siwsbzvs) · Coins Bench · 3 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#blockchain](https://daily.dev/tags/blockchain), [#smart-contracts](https://daily.dev/tags/smart-contracts) [View this post on daily.dev](https://daily.dev/posts/the-one-thing-every-smart-contract-auditor-misses-bgrhxevtu)
