CAPEC-598 Metadata
Likelihood of Attack
High
Typical Severity
Very High
Overview
Summary
An adversary sends a malicious ("NXDOMAIN" ("No such domain") code, or DNS A record) response to a target's route request before a legitimate resolver can. This technique requires an On-path or In-path device that can monitor and respond to the target's DNS requests. This attack differs from BGP Tampering in that it directly responds to requests made by the target instead of polluting the routing the target's infrastructure uses.
Prerequisites
On/In Path Device
Potential Solutions / Mitigations
Design: Avoid dependence on DNS Design: Include "hosts file"/IP address in the application Implementation: Utilize a .onion domain with Tor support Implementation: DNSSEC Implementation: DNS-hold-open

|---|---|
| CAPEC-194 | An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation. |
