ColdPress: An Extensible Malware Analysis Platform for Threat Intelligence

Haoxi Tan, Mahin Chandramohan, Cristina Cifuentes et al.

Malware analysis is still largely a manual task. This slow and inefficient approach does not scale to the exponential rise in the rate of new unique malware generated. Hence, automating the process as much as possible becomes desirable. In this paper, we present ColdPress - an extensible malware analysis platform that automates the end-to-end process of malware threat intelligence gathering integrated output modules to perform report generation of arbitrary file formats. ColdPress combines state-of-the-art tools and concepts into a modular system that aids the analyst to efficiently and effectively extract information from malware samples. It is designed as a user-friendly and extensible platform that can be easily extended with user-defined modules. We evaluated ColdPress with complex real-world malware samples (e.g., WannaCry), demonstrating its efficiency, performance and usefulness to security analysts.

Industrial Experience of Finding Cryptographic Vulnerabilities in Large-scale Codebases

Ya Xiao, Yang Zhao, Nicholas Allen et al.

Enterprise environment often screens large-scale (millions of lines of code) codebases with static analysis tools to find bugs and vulnerabilities. Parfait is a static code analysis tool used in Oracle to find security vulnerabilities in industrial codebases. Recently, many studies show that there are complicated cryptographic vulnerabilities caused by misusing cryptographic APIs in Java. In this paper, we describe how we realize a precise and scalable detection of these complicated cryptographic vulnerabilities based on Parfait framework. The key challenge in the detection of cryptographic vulnerabilities is the high false alarm rate caused by pseudo-influences. Pseudo-influences happen if security-irrelevant constants are used in constructing security-critical values. Static analysis is usually unable to distinguish them from hard-coded constants that expose sensitive information. We tackle this problem by specializing the backward dataflow analysis used in Parfait with refinement insights, an idea from the tool CryptoGuard. We evaluate our analyzer on a comprehensive Java cryptographic vulnerability benchmark and eleven large real-world applications. The results show that the Parfait-based cryptographic vulnerability detector can find real-world cryptographic vulnerabilities in large-scale codebases with high true-positive rates and low runtime cost.
