• Selfish Mining: This occurs when miners keep blocks secret to gain an advantage over others.
• Eclipse Attacks: An attacker isolates a node from the network, allowing them to control its view of the blockchain.

Smart Contract Exploits

Smart contracts can have vulnerabilities that attackers exploit. Some common issues include:

• Reentrancy Attacks: An attacker repeatedly calls a function before the previous call finishes, allowing them to steal funds.
• Integer Overflow/Underflow: This happens when calculations exceed the maximum or minimum limits, leading to unexpected results.
• Gas Limit Vulnerabilities: If a contract runs out of gas, it can fail, leading to potential losses.

DeFi Protocol Vulnerabilities

Decentralized Finance (DeFi) protocols introduce new risks due to their complexity. Some notable vulnerabilities include:

• Flash Loan Attacks: Attackers take out loans without collateral to manipulate prices.
• Oracle Manipulation: This involves tampering with data feeds to affect smart contracts.
• Governance Exploits: Weak governance structures can be manipulated to favor attackers.

Understanding these threats is essential for maintaining the security of blockchain systems. By being aware of potential vulnerabilities, organizations can better protect their assets and users.

In summary, while blockchain technology offers many benefits, it is not immune to attacks. Continuous monitoring and updates are necessary to safeguard against these threats.
