Areas of Vulnerability
- 51% Attacks: If a single entity controls more than 50% of the network’s hashing power, they could manipulate the blockchain․
- Social Engineering: Attackers may deceive users into revealing their private keys․
- Exchange Hacks: Cryptocurrency exchanges, where users store their crypto, are often targets․
- Smart Contract Vulnerabilities: Flaws in smart contract code can be exploited․
Real-World Examples
Recent reports indicate that major cryptocurrency exchanges have suffered significant outflows after alleged hacks․ North Korean Lazarus Group are believed to be involved in attacks․
Defense Mechanisms
Architectures like Hyperledger offer enhanced security․ Blockchain can also be used for DDoS protection․ Furthermore, blockchain can be used to identify fake products, verifying their authenticity․
Blockchain is generally secure, but it’s not foolproof․ Vigilance, secure practices, and robust security measures are crucial to mitigate risks․
