Wormhole Hack - It May Not Be a Bad Thing Wormhole got hacked and lost $321 million in the recent hacking incident. Wormhole is a cross-chain message-passing protocol that connects Solana, Ethereum, Terra, and Binance Smart Chain. **TL;DR** Wormhole got hacked. Solana got its first hacking incident. It is an opportunity for Solana to improve its security. **Hacking** The hacker was able to mint 120K Wormhole-wrapped Ether on Solana. They then bridged 93,750 of these tokens to Ethereum and withdrew the unwrapped Ether.  **Vulnerability** The signature verification is a vulnerable point to let attackers insert commends and false messages so that they can bypass Wormhole’s verify_signatures function to fool the code and successfully withdraw Ethers from the network. **Solana Security Hole** Solana has a security vulnerability that needs to be fixed. It helps the blockchain to improve but at the same time makes Solana worth hacking. **Cross-Chain Vulnerability** Running cross-chain is always a risky business. It tests all cross-chain platform security and its own security. Hackers love to challenge such platforms and to find a loophole to take massive funds away. **In Conclusion** Hacking will never stop until the blockchain has improved to become unhackable.
