In this section we will learn how to use PowerShell Empire.

Let’s start by running PowerShell Empire.

sudo powershell-empire server

struct note
{
    size_t body_sz;
    char body[];
};

struct note* add_note(char* body, size_t body_sz) {
    //cout << sizeof(struct note) << endl;
    unsigned note_sz = sizeof(struct note) + body_sz;

    // overflow checking 
    if (note_sz <= sizeof(struct note)) return NULL;
    struct note *new_note = (struct note*)malloc(note_sz);
    if (new_note == NULL) return NULL;

    memset(new_note, 0, sizeof(struct note));
    new_note->body_sz = body_sz;
    strncpy(new_note->body, body, note_sz - sizeof(struct note));
    return new_note;

}

void dump_note(struct note* note , char* out ) {
    memcpy(out, note->body, note->body_sz);
}
