What can hacker do with name server?

DNS hijacking attack types

What can you do with a name server?

Nameservers play an essential role in directing traffic on the Internet by helping to connect your domain name with the IP address of your web server. To do this, they help web browsers and other services access your domain's DNS records.

What are examples of name servers?

Thanks to nameservers, browsers like Google Chrome and Mozilla Firefox can direct users to the right page when they type in a site address. For example, if you type “myblog.com” into Google, the nameserver tells the browser where that domain is located (i.e., the address of your web host).

What does a name server contain?

The authoritative nameserver contains information specific to the domain name it serves (e.g. google.com) and it can provide a recursive resolver with the IP address of that server found in the DNS A record, or if the domain has a CNAME record (alias) it will provide the recursive resolver with an alias domain, at ...

How could DNS be abused by attackers?

Yet DNS, like any other protocol on the internet, can be manipulated and exploited. A malicious attacker can take advantage of the domain name resolution by attacking the DNS server and changing its records to return incorrect information about domain names or websites instead of their correct IP addresses.

What are the dangers of DNS?

DNS as a security vulnerability

The most common DNS risks include denial-of-service (DoS), distributed denial-of-service (DDoS), DNS hijacking, DNS spoofing, DNS tunneling, DNS amplification, DNS typosquating.

How does the DNS server know IP address?

The Internet's DNS system works much like a phone book by managing the mapping between names and numbers. DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser. These requests are called queries.

What happens during a DNS lookup?
