What is a DNS Exploit?
A DNS Exploit is a vulnerability in the domain name system (DNS) through which an attacker an infiltrate a network.
A 2016 Infoblox Security Assessment Report analyzing 559 files of captured DNS traffic, found that 66 percent of the files showed evidence of suspicious DNS exploits. Among the specific DNS exploit security threats identified, ranked by percentage, are:
- Protocol anomalies – 48%
- DNS tunneling – 40%
- Botnets – 35%
- Amplification and reflection traffic – 17%
- Distributed denial of service (DDoS) traffic – 14%
- Ransomware – 13%
Infoblox Actionable Network Intelligence mitigates the risk of DNS exploits through advanced technologies that analyze DNS traffic to help prevent data exfiltration; disrupt advanced persistent threat (APT) and malware communications; and provide context around attacks and infections on the network.
