How AI can help prevent 'catastrophic forgetting' of malware data

With large numbers of new samples appearing every day the old signature-based methods of malware detection have become unwieldy. AI can learn from millions of samples, but if it uses all samples for optimum detection that means slower learning and updates. The alternative is to use only select samples to keep up with the rate of change of malware, but this runs the risk of 'catastrophic forgetting ' of older patterns. The SophosAI team have been evaluating these options to see if it's possible to have a fine-tuning model that can keep up with the evolving threat landscape without harming… [Continue Reading]
