Evidence
We found insecure EDNS configuration on the following nameservers: ns-1708.awsdns-21.co.uk, ns-913.awsdns-50.net ns-1708.awsdns-21.co.uk:
ns-913.awsdns-50.net:
Vulnerability description
We found that the server does not properly implement EDNS (Extension Mechanisms for DNS). EDNS allows larger DNS packets and supports modern features such as DNSSEC.
Risk description
The risk exists because improper or missing EDNS support can lead to truncated responses, degraded DNS performance, and compatibility issues with DNSSEC. This exposes users to risks such as incomplete DNS resolution and failed DNSSEC validation.
Recommendation
We recommend ensuring the proper implementation of EDNS on the DNS server. Update the DNS server software to support EDNS fully, including modern features like DNSSEC. Regularly test DNS configurations to ensure compliance and performance.
Evidence
We found insecure DNS cookie usage on the following nameservers: ns-1137.awsdns-14.org, ns-1708.awsdns-21.co.uk, ns-213.awsdns-26.com, ns-913.awsdns-50.net
Vulnerability description
We found that the server does not implement DNS Cookies or uses them insecurely. DNS Cookies help prevent DNS-based attacks, such as spoofing and amplification attacks.
Risk description
The risk exists because without DNS Cookies, the server is vulnerable to DNS spoofing and amplification attacks. Attackers can manipulate responses or use the server in distributed denial-of-service (DDoS) attacks, compromising network availability and security.
Recommendation
We recommend enabling DNS Cookies to prevent spoofed DNS responses. Ensure proper cookie validation is implemented to mitigate DNS amplification attacks. Regularly update DNS servers to support the latest DNS security features.

Vulnerability description
We noticed that server software and technology details are exposed, potentially aiding attackers in tailoring specific exploits against identified systems and versions.
Risk description
The risk is that an attacker could use this information to mount specific attacks against the identified software type and version.
Recommendation
We recommend you to eliminate the information which permits the identification of software platform, technology, server and operating system: HTTP server headers, HTML meta information, etc.

Risk description
An initial step for an attacker aiming to learn about an organization involves conducting searches on its domain names to uncover DNS records associated with the organization. This strategy aims to amass comprehensive insights into the target domain, enabling the attacker to outline the organization's external digital landscape. This gathered intelligence may subsequently serve as a foundation for launching attacks, including those based on social engineering techniques. DNS records pointing to services or servers that are no longer in use can provide an attacker with an easy entry point into the network.
Recommendation
We recommend reviewing all DNS records associated with the domain and identifying and removing unused or obsolete records.
