In recent years there has been an increasing demand for sensitive data tracing for industrial microservices these include change of governance data breach detection to data consistency validation As an information tracking technique Taint analysis is widely used to address these demands This paper aims to share our experience in developing a scalable static taint analyzer on sensitive data tracing for large scale industrial microservices Although several taint analyzers have been proposed for Java applications our experiments show that existing approaches are inefficient and or ineffective in terms of low recall precision rates for analyzing large scale industrial microservices Instead we present CFTaint a compositional field based taint analyzer to address the challenges for popular microservices running on industrial Fintech applications CFTaint improves scalability by using a fast compositional function summary which summarizes the data propagation of each function during the on the fly taint analysis CFTaint also uses a novel filed based algorithm to analyze the taint propagation based on specified sensitive fields to reduce false negatives Our field based algorithm maximizes the soundness of our approach even when the taint tracking is performed on an unsound call graph Furthermore we also propose an efficient code transformation method to model the behaviours of the containers which allows our analysis to trace data propagation in a container environment Experiments on numerous production microservices demonstrate the high recall 96 09 rates and precision 93 51 for tracing sensitive data of CFTaint with low time complexity 121 73 seconds
