In a DNS rebinding attack, the attacker first gains control of initial setup involves an attacker gaining control over a malicious DNS server . This server that responds to queries for a specific domain. The attacker then employs attack progresses as the attacker uses tactics like phishing to deceive the user into visiting the malicious domain in their browser, which triggers a DNS request for the associated IP address. Initially, the attacker's server provides the correct a legitimate IP address , but it sets a very short the time-to-live (TTL) of one second for the this DNS record to one second, ensuring it doesn't stay in the cache for long. For preventing it from being cached. Subsequently, any further DNS requests , the attacker swaps in an are manipulated by replacing the original IP address with one that points to targets a resource on the victim’s local network, such as an internal server or device.
This action effectively bypasses the same-origin policy (SOP) restrictions , enabling within the victim's browser, allowing the attacker to carry out execute harmful actions within the browser. DNS rebinding attacks can be used to steal like stealing sensitive data, disrupt disrupting business operations, perform unauthorized activities, or set setting the stage for more extensive attacks. Enabling certain To combat such threats, enabling specific security settings can prevent DNS rebinding attacks. It's important to remember that DNS rebinding exploits the inherent trust browsers place in the Domain Name System, posing serious security risks if not addressed effectively.
