While the bits are scrambled from one example to the next, he has found that using a space filling curve makes it easy to cluster together polymorphically similar malware samples. Forming the fingerprint using these curves is computationally expensive. This is an Internet-scale problem which means he currently needs to inspect 300,000 new samples a day. Switching to a GPU to do the calculation proved four orders of magnitude efficiency over CPUs to reach about 200,000 samples a day. Rick has begun testing FPGA processing, aiming at a goal of processing 10 million samples in four hours using a machine drawing 4000 Watts.
