A cyber attack known as ” web cache poisoning” uses cache storage systems to propagate malicious data to unsuspecting users.When an attacker is successful in poisoning a cache, they can change the content that users receive by sending them to fake websites, introducing malware, or stealing personal data.
According to experts, cybercriminals use several types of techniques in a DNS cache poisoning attack to swap out the real addresses in a DNS cache with fake ones. The DNS resolver hijacks the browser session and directs users to a malicious or fake website when they try to access a legitimate website by returning the false URL in its cache.
The attacker start identifying which website resources are cached. Based on the URL or request headers, they search for pages or resources that the cache could have stored.
After that, the attacker creates a request with harmful content. To ensure that the response is stored in the cache, this request will appear to be legitimate.
After processing the request, the server provides a response that is cached. The malicious content will be stored if the cache server does not verify the request.
The malicious version then served by the cache rather than the authentic one when a user requests the cached resource.
Domain Name System Security Extensions (DNSSEC) are one of the best ways to prevent DNS cache poisoning.
A collection of protocols known as DNSSEC is designed to guarantee the origin and integrity of DNS data that is stored.
Use a various tools, such as Param Miner, to find unlinked, hidden parameters. It is very helpful in identifying vulnerabilities related to web cache poisoning.
