  2. Return-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Return-oriented_programming

    Return-oriented programming (ROP) is a computer security exploit technique that allows an attacker to execute code in the presence of security defenses [1] [2] such as executable space protection and code signing. [3]

  3. Arbitrary code execution - Wikipedia

    en.wikipedia.org/wiki/Arbitrary_code_execution

    On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...

  4. Code injection - Wikipedia

    en.wikipedia.org/wiki/Code_injection

    Here, the code under attack is the code that is trying to check the parameter, the very code that might have been trying to validate the parameter to defend against an attack. [ 20 ] Any function that can be used to compose and run a shell command is a potential vehicle for launching a shell injection attack.

  5. Logic bomb - Wikipedia

    en.wikipedia.org/wiki/Logic_bomb

    A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.

  6. Heap spraying - Wikipedia

    en.wikipedia.org/wiki/Heap_spraying

    The part of the source code of an exploit that implements this technique is called a heap spray. [1] In general, code that sprays the heap attempts to put a certain sequence of bytes at a predetermined location in the memory of a target process by having it allocate (large) blocks on the process's heap and fill the bytes in these blocks with ...

  7. SpyEye - Wikipedia

    en.wikipedia.org/wiki/SpyEye

    SpyEye is a malware program that attacks users running Google Chrome, Safari, Opera, Firefox and Internet Explorer on Microsoft Windows operating systems. [1] This malware uses keystroke logging and form grabbing to steal user credentials for malicious use.

  8. Shellcode - Wikipedia

    en.wikipedia.org/wiki/Shellcode

    Download and execute is a type of remote shellcode that downloads and executes some form of malware on the target system. This type of shellcode does not spawn a shell, but rather instructs the machine to download a certain executable file off the network, save it to disk and execute it.

  9. Interpreter (computing) - Wikipedia

    en.wikipedia.org/wiki/Interpreter_(computing)

    Interpretation cannot be used as the sole method of execution: even though an interpreter can itself be interpreted and so on, a directly executed program is needed somewhere at the bottom of the stack because the code being interpreted is not, by definition, the same as the machine code that the CPU can execute.
