🚹 BLOCKCHAIN HACKS: WEEKLY RECAP 🚹 Over $12M was drained this week. Again. Same bugs, same failures, same headlines. Here are the Top 10 recurring attack vectors we still haven’t learned from, and what made @Corkprotocol the hack-of-the-week. đŸ§”
1/ The @Corkprotocol exploit wasn’t fancy. Just a classic kill chain featuring: 🛑 Insufficient function access control 🎯 Price oracle manipulation 💰 Reward manipulation That’s 3 textbook bugs, and $12M gone.
These aren’t zero-days. These are known, avoidable, and documented. We still think “smart contract audit” = security. Spoiler: it doesn’t.
Let’s talk about Reward Manipulation. It’s when an attacker extracts fees/yield/emissions without risk or real value. Your protocol gets farmed. You lose. đŸ”„ See: Abracadabra ($13M) @picklefinance ($19.7M) @eulerfinance ($197M)
Then there’s the Price Oracle Manipulation playbook. Still works in 2025. Still wrecking DeFi. If your oracle relies on thin liquidity, you’ve already lost. @chainlink isn’t immune either (see deUSD’s $500K liquidation this week)
Access Control Failures One of the most boring, basic, and frequent failures. Missing onlyOwner, unchecked function calls, role mismanagement. and welcome back, Integer Overflow. Yes, the bug we thought we left in 2018 is back thanks to @CetusProtocol on @SuiNetwork. $260M, gone. Because someone didn’t check their math.
New entry on the leaderboard: Supply Chain Attacks Think Web2 vibes: - Infected NPM packages - compromised build tools - CI/CD pipeline exploits DevSecOps isn’t optional anymore. Audit your whole stack or enjoy the rug.
Security isn’t just on-chain. It’s your endpoint. It’s your infra. It’s your key management. Stolen private keys still lead the charts. And no audit can save you from sloppy ops.
Blockchains aren’t broken. We are. Every week, the same bugs. The same losses. The same post-mortems. Rug season ends when the space grows up.
