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.
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 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 ]
In May 2013 a member of Google Chrome's Site Isolation Team announced on the chromium-dev mailing list that they would begin landing code for out-of-process i-frames (OOPIF). [1] This was followed by a Site Isolation Summit at BlinkOn in January 2015, which introduced the eight-engineer team and described the motivation, goals, architecture ...
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.

Christmas can already be stressful enough. The last thing you want is anxiety about your pet's health. Here's how to cat-proof your home this holiday.
[11] [12] This type of encoding was created by hackers to hide working machine code inside what appears to be text. This can be useful to avoid detection of the code and to allow the code to pass through filters that scrub non-alphanumeric characters from strings (in part, such filters were a response to non-alphanumeric shellcode exploits).
