Execution Flow

Identify potential DNS rebinding targets: An adversary publishes content on their own server with their own name and DNS server. Attract HTTP traffic and explore rebinding vulnerabilities in browsers, flash players of old version.

Techniques
Adversary uses Web advertisements to attract the victim to access adversary's DNS. Explore the versions of web browser or flash players in HTTP request.

Establish initial target access to adversary DNS: The first time the target accesses the adversary's content, the adversary's name must be resolved to an IP address. The adversary's DNS server performs this resolution, providing a short Time-To-Live (TTL) in order to prevent the target from caching the value.
Rebind DNS resolution to target address: The target makes a subsequent request to the adversary's content and the adversary's DNS server must again be queried, but this time the DNS server returns an address internal to the target's organization that would not be accessible from an outside source.
Determine exploitability of DNS rebinding access to target address: The adversary can then use scripts in the content the target retrieved from the adversary in the original message to exfiltrate data from the named internal addresses.

Access & exfiltrate data within the victim's security zone: The adversary can then use scripts in the content the target retrieved from the adversary in the original message to exfiltrate data from the internal addresses. This allows adversaries to discover sensitive information about the internal network of an enterprise.

Techniques
Adversary attempts to use victim's browser as an HTTP proxy to other resources inside the target's security zone. This allows two IP addresses placed in the same security zone.
Adversary tries to scan and access all internal hosts in victim's local network by sending multiple short-lived IP addresses.
