DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
Most hijacking programs constantly change the settings of browsers, meaning that user choices in their own browser are overwritten. Some antivirus software identifies browser hijacking software as malicious software and can remove it. Some spyware scanning programs have a browser restore function to set the user's browser settings back to ...
Using proxy or vpn, system wide, via 3rd party app helpers like Proxifier, or in form of web browser extension. However most extensions in Chrome or Firefox will report false positive working condition even if they did not connect, so 3rd party website for ip and dns leak check is recommended. This false working state usually happens when two ...
Typosquatting, also called URL hijacking, a sting site, a cousin domain, or a fake URL, is a form of cybersquatting, and possibly brandjacking which relies on mistakes such as typos made by Internet users when inputting a website address into a web browser. A user accidentally entering an incorrect website address may be led to any URL ...
HSTS addresses this problem [2]: §2.4 by informing the browser that connections to the site should always use TLS/SSL. The HSTS header can be stripped by the attacker if this is the user's first visit. Google Chrome, Mozilla Firefox, Internet Explorer, and Microsoft Edge attempt to limit this problem by including a "pre-loaded" list of HSTS sites.
Man-in-the-browser (MITB, MitB, MIB, MiB), a form of Internet threat related to man-in-the-middle (MITM), is a proxy Trojan horse [1] that infects a web browser by taking advantage of vulnerabilities in browser security to modify web pages, modify transaction content or insert additional transactions, all in a covert fashion invisible to both the user and host web application.
Comparing domain names is an essential part of enforcing this policy, so DNS rebinding circumvents this protection by abusing the Domain Name System (DNS). This attack can be used to breach a private network by causing the victim's web browser to access computers at private IP addresses and return the results to the attacker.
DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks [1] by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver.
