3. Dynamic API Resolution
The ResolveImport function dynamically resolves Windows API functions by loading the required DLLs and identifying functions by their hashed names. This is an obfuscation and anti-analysis technique to hide API calls.
It is specifically designed to resolve APIs like NtAllocateVirtualMemory.
4. Memory Allocation
MalwareMain uses the resolved API NtAllocateVirtualMemory to allocate memory in the process space. This allocated memory could be used for malicious purposes such as:
Injecting malicious code.
Executing a payload from memory.
The allocation is made with read-write permissions (PAGE_READWRITE).

5. Custom Hashing
The fnv1a_salted function calculates a hash value using the FNV-1a algorithm, which is commonly used in malware for:
Obfuscating strings or API names.
Making it harder for analysts to interpret the payload.
The provided test values demonstrate hashing of DLL and function names (ntdll and LdrLoadDll) with a specific salt.
