How SARVAM Works

SARVAM uses a simple yet effective method for visualizing and classifying malware using image processing techniques. Malware binaries are visualized as gray-scale images, with the observation that for many malware families, the images belonging to the same family appear very similar in layout and texture.

Most of the new malware are modifications of existing malware. Thus the variants have almost the same content. For goodware, the newer versions usually have small additions/modifications to the previous versions. We maintain a database of more than 4 Million binaries comprising a blacklist of malware and a whitelist of goodware.

Users can upload new binaries and obtain the top matches using signal processing algorithms.

How long does it take to find a Match?

Computing Image based Similarity Feature: 50 ms

Finding Nearest Neighbor Matches with a 4 Million Malware Database on a single machine: 2 s (even faster matching time possible)

Some other peculiar Examples
