What type of attack exploits the DNS?

A DNS spoofing attack specifically targets the Domain Name System (DNS) to manipulate the resolution of domain names into IP addresses. In such an attack, the attacker provides false DNS responses that redirect users to malicious sites instead of legitimate ones. This can occur through various means, such as sending fraudulent DNS responses or corrupting cache entries on DNS servers, allowing the attacker to control where users are directed when they attempt to reach certain websites.

This type of attack is particularly dangerous because it can lead users to believe they are visiting a trusted site while they are actually interacting with a malicious or compromised one. By exploiting the fundamental trust that users place in DNS to resolve domain names correctly, DNS spoofing undermines the security of internet navigation, making it a significant threat in cybersecurity.

In contrast, the other options pertain to different attack vectors: SQL injection focuses on manipulating SQL queries to access or alter database information, phishing involves tricking individuals into providing sensitive information by imitating trustworthy entities, and Denial of Service attacks aim to overwhelm a target's resources to cause service unavailability. Each of these attacks operates in distinct ways and targets different components of a network or application, rather than directly manipulating DNS.
