What is a characteristic of a DNS amplification and reflection attack?
- Threat actors hide their phishing and malware delivery sites behind a quickly-changing network of compromised DNS hosts.
- Threat actors use malware to randomly generate domain names to act as rendezvous points.
- Threat actors use DNS open resolvers to increase the volume of attacks and to hide the true source of an attack.
- Threat actors use a DoS attack that consumes the resources of the DNS open resolvers.
Explanation: Threat actors use DNS open resolvers to increase the volume of attacks and to hide the true source of an attack by sending DNS messages to the open resolvers and using the IP address of a target host (victim).
