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.
Domain Name System blocking, or DNS blocking / filtering, is a strategy for making it difficult for users to locate specific domains or websites on the Internet. It was first introduced in 1997 as a means to block spam email from known malicious IP addresses .
DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.
[11] Even though GNSS is one of the most relied upon navigational systems, it has demonstrated critical vulnerabilities towards spoofing attacks. GNSS satellite signals have been shown to be vulnerable due to the signals’ being relatively weak on Earth’s surface, making GNSS signals ultimate targets for spoofing attacks.
By Raphael Satter and AJ Vicens-Hackers have compromised several different companies' Chrome browser extensions in a series of intrusions dating back to mid-December, according to one of the ...
An effective attack against DNS might involve targeting top-level domain servers (such as those servicing the .com domain) instead of root name servers. Alternatively, a man-in-the-middle attack or DNS poisoning attack could be used, though they would be more difficult to carry out.
An 11% slide in sales last quarter is raising concerns about Apple amid tough competition in China. DeepSeek may not have triggered a sell-off panic for Apple, but the iPhone maker has another ...
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.
