Calling convention: determines the order of the incoming and outgoing stacks when the function parameter is transferred. The caller or the caller pushes the parameter to the stack and the modifier Convention used by the compiler to identify the function name.
There are many function call conventions. Here is a simple introduction:1. The _ stdcall cal

When calling a function, there are various call conventions. They specify the parameter transfer method, whether the parameter is variable, and who handles the stack. There are two common call Conventions: C language and Pascal Language.You can set the call rules for custom functions in the Project Settings, you can also add keywords or API macro definitions (such as _ cdecl, _ stdcall, _ fastcall, WINAPI, and APIENTRY) before function names during function declaration and definition) specify th

In Microsoft C ++ C/C ++ compilers, Pascal macro is often used to declare this call
C Name Decoration rules1. For functions that use the __cdecl calling convention, add a dash before the function name, regardless of the parameter and return value.2. For functions that use the __fastcall calling convention, add an @ sign before and after the function name, followed by the length of the parameter, regardless of the return value.For example, the decorated name of extern "C" int __fastcall Tes

As you can see, for a fixed number of parameters, it is similar to stdcall, and is similar to cdecl.

is a relatively rare calling method, which is uncommon in general advanced programming languages.
The declaration invocation of a function must be the same as the actual invocation method, and the compiler will inevitably create confusion.

Stack heap analysis shows that the top parameters of the stack are pressed at the bottom of the stack from left to right. Unless you know the number of parameters, you cannot obtain the leftmost parameter through the relative displacement of the stack pointer. This makes the number of parameters on the left uncertain,

A calling convention is the method by which a program passes parameters and gets return values when a function is called: by register, or by a stack, or by a mixture of the two. The modifiers used to specify calling convention mainly include: __cdecl,__stdcall,__fastcall, and so on. The calling convention can be selected from the project setup: Setting...\c/c++ \

Microsoft recommends the Hungary naming method, which is also applicable to most software production. The detailed rules are as follows:
The Hungarian naming convention is a naming convention for programming. The basic principle is: variable name = Attribute + Type + object description. Each object name must have a clear meaning. You can take the full name or part of the object name. Naming should be base
1. Save the Register
First, the C false Stator
Program The values of the following registers are saved: EBX, ESI, EDI, EBP, Cs, DS, SS, and es. This does not mean that they cannot be modified within the subroutine. Instead, it indicates that if the subroutine changes their values, the original values must be restored before the subroutine returns. Values of EBX, ESI, and EDI cannot be changed because C uses these registers for register variables. Generally, the stack is used to save the origina

(including the target files driving the C code) during the link period. However, the built-in build program of DDK does not directly support Compilation and linking of assembly files (or I have not found such a method ). Therefore, you need to use other means to link the Assembly Code target file with the C Code target file. The method described in this article is to call an independent assembler function in a Windows Driver by modifying the source file and forcing the specified external functi

In this case, the target files are compiled by different compilers. obj is not universal, because the same function, using different name-mangling, will have different names in the obj file.

In a multithreaded (task) environment, the memory area that the CPU's stack pointer points to is the stack that is currently in use. One important task of switching threads is to set the stack pointer to the top address of the stack stack of the current thread.

Like most Android banking trojans, Anubis monitors the startup of the target application and then uses the corresponding phishing screen to overwrite valid applications to steal the creden of victims. Finally, it uses its SMS Interception Function to intercept any subsequent security code sent by the bank.
PhishLabs said they found 275 different apps around the world carrying Anubis, including 29 apps related to cryptocurrency
