int main() {
   // Craft a malicious attachment
   FILE *attachment;
   attachment = fopen("CVE-2023-41061_exploit.txt", "wb");

   if (attachment == NULL) {
       printf("Error opening file.\n");
       exit(EXIT_FAILURE);
   }

   // Write exploit code to the attachment
   char exploit_str[] = "Malicious code designed to exploit CVE-2023-41061 vulnerability";
   fwrite(exploit_str, sizeof(char), sizeof(exploit_str), attachment);
   fclose(attachment);

   return ;
}
