Zero Trust API Bind (TAB) redefines runtime API security for mobile apps by binding every request to a verified app instance and live runtime signals. Discover how dynamic tokens and real-time validation stop API abuse, replay attacks, and fraud, unlocking a new standard of protection for fintech, banking, and payment applications.

SIM binding is widely used in mobile payment and fintech apps as a core security control to ensure that only the registered SIM and device can initiate transactions. However, real-world testing shows that this mechanism is often built on assumptions that no longer hold true in modern threat environments. This case study breaks down the SIM binding process, highlights where current implementations fall short, and explains how these gaps can lead to full account takeover. It also emphasizes the need for runtime protection and stronger validation mechanisms to defend against evolving mobile threats.

Explore how cloud-based RASP solution enhance runtime security by enabling informed decisions, faster analyses, and continuous protection.

A real fintech case study on detecting cyber attacks and account takeover fraud using red teaming in a UPI Payment Service Provider company with 10 crore+ users. Read how Bugsmirror was engaged to investigate an attack affecting users' money and the company's reputation.

A guide to PCI CPoC security requirements, focusing on tamper resistance, reverse-engineering protection, and securing contactless payment apps.

Your app may look secure, but it could already be under attack. Recent analysis shows that compromised devices are accessing trusted app flows, modified apps and emulators are bypassing device binding and runtime checks, and hidden traffic interception is slipping past basic security controls. As these trends continue into 2026, apps that rely on assumed trust instead of enforced runtime security remain exposed, and without timely action, exploitation becomes inevitable…

Mobile applications have become the backbone of modern business growth, powering everything from customer engagement to digital payments. But with this dependency comes a growing risk — attackers constantly look for weaknesses to exploit, and traditional Vulnerability Assessment and Penetration Testing (VAPT) is no longer enough. While VAPT identifies risks, it often lags behind fast release cycles, leaving businesses exposed between testing windows.

Bugsmirror was tasked with auditing a leading FinTech mobile application that served over a million users. Despite the application being certified compliant with major financial regulations and having passed previous VAPT (Vulnerability Assessment & Penetration Testing) checks, our team uncovered critical, high-risk vulnerabilities that exposed the company and its users to severe threats.

The Reserve Bank of India’s Master Direction on Digital Payment Security Controls mandates robust security for payment systems under the Banking Regulation Act, 1949. For organizations offering mobile payment solutions, this is non-negotiable. Bugsmirror MASST empowers you to comply with RBI’s security framework effortlessly, mitigating risk from data breaches, reverse engineering, and runtime exploits—all while safeguarding your customers’ trust.
