Description

Recently, several deep learning approaches have attempted to detect malware binaries using convolutional neural networks and stacked deep autoencoders. Although they’ve shown respectable performance on a large corpus of datasets, practical defense systems require precise detection during the malware outbreaks where only a handful of samples are available.

Sean Park demonstrates the effectiveness of the latent representations obtained through the adversarial autoencoder for malware outbreak detection. Using instruction sequence distribution mapped to a semantic latent vector, the model provides a highly effective neural signature that helps detecting variants of a previously identified malware within a campaign mutated with minor functional upgrade, function shuffling, or slightly modified obfuscations. Sean explains the effectiveness of generative adversarial autoencoders for static malware detection under outbreak situations where a single sample of a kind is available to detect similar in-the-wild samples. The model performance is evaluated over real-world macOS and Windows malware samples against traditional machine learning models.
