Computer Hacking Forensic Investigator (CHFI v10) — Question 474

Simon is a former employee of Trinitron XML Inc. He feels he was wrongly terminated and wants to hack into his former company's network. Since Simon remembers some of the server names, he attempts to run the axfr and ixfr commands using DIG. What is Simon trying to accomplish here?

Answer options

• A. Send DOS commands to crash the DNS servers
• B. Perform DNS poisoning
• C. Perform a zone transfer
• D. Enumerate all the users in the domain

Correct answer: C

Explanation

The correct answer is C, as the axfr and ixfr commands are specifically used for performing zone transfers, which allow the retrieval of DNS records from a DNS server. The other options do not relate to these commands; A refers to denial-of-service attacks, B pertains to corrupting DNS data, and D involves user enumeration, none of which are accomplished through zone transfers.
