A buffer overflow attack occurs when a program writes more data to a buffer—a temporary storage location—than it can hold. This excess data can overwrite adjacent memory locations, potentially allowing an attacker to manipulate the program’s execution flow.In the context of cryptocurrencies, this type of vulnerability can be exploited in wallet software, exchanges, or smart contracts. Attackers could inject malicious code, causing unexpected behaviors such as unauthorized fund transfers or crashing the application.Once exploited, the attacker might gain control over the affected program, enabling them to steal funds or gain access to sensitive information. Such attacks can compromise the security and integrity of blockchain networks.To mitigate buffer overflow attacks, developers should follow best practices like input validation, using safe programming languages, and regularly updating their software. Ensuring robust security measures is critical to protecting assets and maintaining user trust.
