In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability.It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.
In computing and telecommunications, the payload is the part of transmitted data that is the actual intended message. Headers and metadata are sent only to enable payload delivery [1] [2] and are considered overhead. In the context of a computer virus or worm, the payload is the portion of the malware which performs malicious action.
Blackhole exploit kit was released on "Malwox", an underground Russian hacking forum. It made its first appearance in 2010. [5]The supposedly Russian creators use the names "HodLuM" and "Paunch".
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.
CryptoLocker typically propagated as an attachment to a seemingly innocuous email message, which appears to have been sent by a legitimate company. [5] A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension.
Code injection is a computer security exploit where a program fails to correctly process external data, such as user input, causing it to interpret the data as executable commands. An attacker using this method "injects" code into the program while it is running.
In computer security, heap spraying is a technique used in exploits to facilitate arbitrary code execution.The part of the source code of an exploit that implements this technique is called a heap spray. [1]
A softmod (short for software modification) is a method of using software to modify the intended behavior of hardware, such as computer hardware, or video game consoles in a way that can overcome restrictions of the firmware, or install custom firmware.
