  • VBA project inside OOXML medium 4 related findings OOXML_VBA
    Document contains a VBA project — VBA macros present
  • VBA native-memory callback shellcode loader critical OLE_VBA_NATIVE_MEMORY_CALLBACK_LOADER
    VBA auto-exec macro declares or calls native memory allocation, process-memory write/copy, and callback/timer execution APIs. This is the in-memory shellcode loader pattern: allocate writable memory, copy decoded payload bytes into it, then transfer control through a callback such as CreateTimerQueueTimer. Benign document automation does not combine these primitives.
