In internet security, DOM clobbering (where DOM stands for Document Object Model) is a type of injection attack that revolves around the attacker being able to insert benign non-script HTML code that can be used to influence the execution of JavaScript code. This enables a skilled attacker to perform a variety of unwanted behaviours, including ...
A polymorphic engine (sometimes called mutation engine or mutating engine) is a software component that uses polymorphic code to alter the payload while preserving the same functionality. Polymorphic engines are used almost exclusively in malware , with the purpose of being harder for antivirus software to detect.
Polymorphic algorithms make it difficult for such software to recognize the offending code because it constantly mutates. Malicious programmers have sought to protect their encrypted code from this virus-scanning strategy by rewriting the unencrypted decryption engine (and the resulting encrypted payload) each time the virus or worm is propagated.
Metamorphic code is used by computer viruses to avoid the pattern recognition of anti-virus software.Metamorphic viruses often translate their own binary code into a temporary representation, editing the temporary representation of themselves and then translate the edited form back to machine code again.

Self-modifying code is also sometimes used by programs that do not want to reveal their presence, such as computer viruses and some shellcodes. Viruses and shellcodes that use self-modifying code mostly do this in combination with polymorphic code. Modifying a piece of running code is also used in certain attacks, such as buffer overflows.
In 2009, Reis et al. proposed the first version of the process-per-site model to isolate web pages based on the page's web origin. [11] This was improved upon in 2009 by the Gazelle research browser, which separated specific document frames based on their web principal, a security barrier that corresponded with the specific document that was being loaded.
An expanding coalition of health and consumer advocates is campaigning against Robert F. Kennedy Jr.'s nomination to the top U.S. health job over concerns about his activism against vaccines and ...
A polymorphic packer is a file binder with a polymorphic engine. It thus has the ability to make its payload mutate over time, so it is more difficult to detect and remove. [ citation needed ]
