PhonePe Launches Nika: New Open-Source Security Tool for Java Microservices

On July 1, 2026, PhonePe, an Indian payments company, released Nika, an open-source code analysis tool aimed at enhancing security in Java microservices. Nika addresses the challenge of identifying vulnerabilities that span multiple files, which traditional single-file scanners often overlook. By performing cross-file taint analysis, Nika traces attacker input through various application layers, making it a valuable resource for developers and security professionals. The tool is designed to detect exploit paths that could lead to serious security breaches. Its release aims to improve the security posture of applications built on Java microservices architecture. As of now, there are no reported vulnerabilities or exploits associated with Nika itself.

Key Points: • Nika is an open-source tool released by PhonePe for Java microservices security. • It performs cross-file taint analysis to detect vulnerabilities missed by single-file scanners. • The tool aims to enhance security in applications by tracing attacker input across layers.
