A downgrade attack, also called a bidding-down attack, [1] or version rollback attack, is a form of cryptographic attack on a computer system or communications protocol that makes it abandon a high-quality mode of operation (e.g. an encrypted connection) in favor of an older, lower-quality mode of operation (e.g. cleartext) that is typically provided for backward compatibility with older ...
Stack Overflow is a question-and-answer website for computer programmers. It is the flagship site of the Stack Exchange Network. [2] [3] [4] It was created in 2008 by Jeff Atwood and Joel Spolsky. [5] [6] It features questions and answers on certain computer programming topics.
The following source code is an example of an API/function hooking method which hooks by overwriting the first six bytes of a destination function with a JMP instruction to a new function. The code is compiled into a DLL file then loaded into the target process using any method of DLL injection. Using a backup of the original function one might ...
Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, usually in order to make the game easier.Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge).
A unit test is code that is written to execute a specific function in the code to be tested and usually targets a small unit of code, such a single method or class. Using a combination of assert statements and other test statements, programmers can create suites of test cases in order to tell if a method or function is being executed properly. [5]
One important case of hard coding is when strings are placed directly into the file, which forces translators to edit the source code to translate a program. (There is a tool called gettext that permits strings to be left in files, but lets translators translate them without changing the source code; it effectively de-hard codes the strings.)
Self-modifying code is sometimes used to overcome limitations in a machine's instruction set. For example, in the Intel 8080 instruction set, one cannot input a byte from an input port that is specified in a register. The input port is statically encoded in the instruction itself, as the second byte of a two byte instruction.
They are usually triggered by some event, such as pushing code to a repository, [3] a new comment or a purchase, [4] a comment being posted to a blog [5] and many more use cases. [6] When that event occurs, the source site makes an HTTP request to the URL configured for the webhook.
