Computer Hacking Forensic Investigator (CHFI) Practice Exam

The type of attack that involves the modification of DNS records is DNS Redirection. This technique occurs when an attacker alters the records in a Domain Name System (DNS) to redirect users from a legitimate site to a malicious one. By changing the DNS records, the attacker can manipulate the traffic flow, making it possible for them to lead unsuspecting users to fraudulent websites, potentially to harvest sensitive information or execute further attacks.

In this context, DNS Redirection relies on compromising the integrity of DNS data, which is crucial for directing user traffic based on domain names. This method can effectively facilitate various other attacks, including phishing or injecting malware, as users are unaware that they are being sent to a harmful site instead of the intended destination.

Other options mention different types of attacks that do not focus specifically on DNS record modification. For instance, a Man-in-the-middle attack primarily involves intercepting communication between two parties without their knowledge. Password cracking refers to methods used to obtain users' passwords, while IP Spoofing is about sending packets from a false IP address to impersonate another host. None of these specifically alter DNS records, making DNS Redirection the correct response for this question.
