DNS is facing a various number of malicious attacks. These are some of the DNS attacks:
- Single point of failure: One failure can result in the simultaneous stopping of the entire system
- Man-in-the-middle (MITM) attacks: During this attack, the attacker intercepts the traffic
- DNS cache poisoning: Here, the attacker redirects the victim to a malicious server
- Kaminsky DNS vulnerability: This vulnerability could allow an attacker to redirect network clients to alternate servers of his own choosing, presumably for ill ends
- Dynamic DNS (DDNS): A malware developer use DDNS to quickly change the address
- Distributed Denial of Service (DDoS) attacks: The attacker floods the target with unhandled requests
