The original form of the pattern, appearing in Pattern Languages of Program Design 3, [2] has data races, depending on the memory model in use, and it is hard to get right. Some consider it to be an anti-pattern. [3] There are valid forms of the pattern, including the use of the volatile keyword in Java and explicit memory barriers in C++. [4]
An attacker could, for example, use a social engineering attack and send a "lucky winner" a rogue Thunderbolt device. Upon connecting to a computer, the device, through its direct and unimpeded access to the physical address space, would be able to bypass almost all security measures of the OS and have the ability to read encryption keys, install malware, or control other system devices.

It is also referred to as first-party DMA , in contrast with third-party DMA where a system DMA controller actually does the transfer.
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.
The syntax for creation and destruction varies by programming context. In many contexts, including C++, C# and Java, an object is created via special syntax like new typename(). In C++, that provides manual memory management, an object is destroyed via the delete keyword. In C# and Java, with no explicit destruction syntax, the garbage ...
