Case File #74: The Keys Stayed Safe—Everything Around Them Didn’t

Your private keys can stay secure and you can still get wrecked. This week, Crypto Sleuth looks beyond the seed phrase and into the expanding security perimeter surrounding your crypto. We break down the Trezor shipping-provider data breach that exposed personal information belonging to nearly 14,000 hardware-wallet customers—and why your home address should now be treated as crypto-security data. Then we investigate the Coreum/XRPL bridge exploit, where nearly 200,000 XRP was drained without compromising the XRP Ledger or stealing private keys. The failure was in the verification logic. We also dig into a growing AI threat: AgentBaiting. Malicious GitHub repositories disguised as legitimate AI Skills and MCP servers are creating a new attack path where scammers don’t just social-engineer people—they social-engineer the AI agents helping them. Plus: 🔐 Why transaction simulations aren’t guarantees 🤖 How to secure AI agents before giving them powerful permissions 🌉 Why bridge security goes far beyond multisig 📝 What token approvals actually allow a smart contract to do 📊 Bitcoin, Ethereum, ETF flows, liquidity and the broader market 🏔️ This week’s Avalanche outlook 💯 Why HundredCoin’s 100-hour mechanic demonstrates a bigger security principle: sometimes friction protects you The lesson from Case File #74 is simple: A secure private key does not automatically mean you have a secure crypto operation. Your identity. Your software. Your approvals. Your infrastructure. Your automation. It’s all part of the security perimeter.
