Protect mobile apps against API Abuse & Unauthorized Access
Mobile applications depend on APIs for authentication, transactions, payments, account management, and access to sensitive data. Attackers can abuse exposed endpoints, manipulate requests, misuse authentication tokens, or exploit weaknesses in application and API controls.
When API requests are treated as inherently trusted, a compromised application or attacker-controlled environment can become a pathway to unauthorized functionality, data exposure, fraud, and transaction manipulation.
What Is API Abuse & Unauthorized Access?
API abuse occurs when attackers exploit weaknesses in API authentication, authorization, request validation, or business logic to access protected resources, manipulate transactions, or execute unauthorized operations. In mobile applications, a critical security gap arises when backend systems implicitly trust API requests simply because they appear to originate from the legitimate application.
Attackers can intercept and replay requests, modify parameters or tokens, invoke APIs directly through tools such as Postman, or generate requests from tampered applications and rooted devices. Even when HTTPS protects data in transit, it does not independently verify that a request originates from an untampered application running in a trusted environment.
Effective mobile API security requires a secure communication layer, runtime application protection, application integrity checks, and server-side validation of application trust signals. These controls help identify manipulated requests and compromised application environments before sensitive API operations are trusted.

API Data Exposure
Server-Side Request Forgery
Why Is API Security Becoming Harder to Maintain?
API Attacks Increased by 113%
The average number of daily API attacks increased by 113% year over year, making APIs an increasingly targeted attack surface for modern enterprises.
3,000 APIs Contained Sensitive Data
An average of 3,000 APIs per customer contained sensitive data, with 12% showing security weaknesses and 24% of those issues involving sensitive data exposure.
61.18% of API Attacks Involved Unauthorized Activity
In 2025, 61.18% of API attacks involved unauthorized workflows and abnormal activity, up sharply from 30.01% in 2024.
BOLA Remains the #1 API Security Risk
Broken Object Level Authorization (BOLA) ranks as the top API security risk in the OWASP API Security Top 10, occurring when APIs fail to properly verify access to specific objects or resources.
API Abuse Can Become Business Risk
When attackers gain unauthorized access to APIs, they can potentially manipulate transactions, access sensitive information, automate account attacks, exploit business logic, or perform actions beyond their intended permissions.
For CISOs, CTOs, Heads of Information Security, AppSec, DevSecOps, developers, and fraud teams, this creates a critical question:
Can your backend distinguish a legitimate API request from a request generated by a compromised mobile application?
Why Is API Security More Than Endpoint Protection?
API gateways, authentication, authorization, rate limiting, and input validation are important security controls. However, these controls may not provide sufficient context when the mobile application itself has been modified, repackaged, hooked, or compromised.
A stronger approach combines:
API Security Testing + Application Integrity + Runtime Threat Detection + Server-Side RASP Validation
Protection should address both the API endpoint and the application making the request.
Runtime security can help identify compromised application environments, while server-side RASP validation can use application and runtime security signals when evaluating sensitive API requests.
What Bugsmirror MASST Delivers?
API Security Testing
APILock helps identify weaknesses across API endpoints, authentication flows, authorization controls, request handling, and exposed application functionality. Testing can cover live and shadow APIs to identify security risks before they can be exploited.
Application & Runtime Integrity
Bugsmirror Defender helps detect application tampering, repackaging, hooking, code injection, debugging, SSL pinning bypass, SSL stripping, use of user generated certificate and other runtime threats that can be used to manipulate application behaviour or API requests.
Server-Side RASP Validation
Trust API Bind helps backend systems validate runtime security signals associated with sensitive API requests, adding an application-trust layer beyond traditional API authentication.
Real-Time Threat Visibility
ThreatLens provides visibility into runtime security events across applications, users, and devices, helping security teams identify suspicious activity and understand how applications are being targeted in production.

Account Takeover Attack: Fraud Toolkits Bypassing UPI Security in Mobile Apps
Millions of UPI transactions happen every day, but what if attackers could bypass the very security mechanisms designed to protect them? Recent fraud toolkits show how cybercriminals are manipulating mobile devices to intercept OTPs and abuse SIM-binding trust. The result is Account Takeover (ATO), where attackers gain control of a victim’s payment account and perform unauthorised transactions. As these attacks evolve, fintech mobile apps must rethink how they defend against runtime threats.
