Nowadays, it can be said that mobile applications have become an unavoidable part of our daily lives as they are used as communication, banking, shopping, and entertainment platforms. Nevertheless, the reliance on mobile apps is also growing, and it is a prime target for cyber threats. VAPT is required to be done by businesses and developers for mobile application security. Mobile App VAPT will find security weaknesses, vulnerabilities, and compromise points that would appeal to a cyber attack. Today, Qualysec Technologies will discuss Mobile Application VAPT, its importance, and the best practices and methodologies required to secure mobile applications in the best possible manner.
Understanding Mobile App VAPT
What is VAPT?
VAPT, or Vulnerability Assessment and Penetration Testing process, is an approach used to check out vulnerabilities on a system, network, or application. The first consists of two basic key components.
- Vulnerability Assessment (VA) – A methodology that scans, analyzes and checks for the security weaknesses and vulnerabilities in the mobile application.
- Penetration Testing (PT) – It is a simulated cyber attack to identify the vulnerabilities and determine the risk that can arise on exploitation of those weaknesses.
Mobile Application VAPT
Mobile App VAPT is a secure testing approach for checking the security signpost of the mobile applications running on Android and iOS. These tests ensure that security flaws, such as insecure data storage, incorrect authentication, code vulnerabilities, and API problems that may reveal sensitive information or allow unauthorized access, are detected.
Importance of Mobile App VAPT
With the increase in the use of mobile applications, the threat to security has risen for businesses and users as well. They have data that is personal, financial and business-related, and hence, they are a prime target for cyber criminals. Vulnerability Assessment and Penetration Testing (VAPT) comes into play in such a scenario.
Protection Against Cyber Threats
Security threats posing risks to mobile applications comprise malware injection, unauthorized access and breaches of any data. With VAPT, you can identify all the security weaknesses and cover them up before attackers take the chance to penetrate. Through this, businesses can perform a thorough mobile app security assessment to protect their apps from cyber threats.
Ensuring Compliance with Security Standards
The mobile applications include the need to comply with security frameworks such as ISO 27001, PCI DSS, GDPR, HIPAA, etc., which are disapproved by regulatory bodies and industry standards. VAPT is conducted to make sure mobile apps comply with these compliance standards, which make mobile apps avoid legal penalties and keep data privacy.
Enhancing User Trust and Business Reputation
A security breach can harm the company’s reputation and customer trust. Data security guaranteeing applications are preferred by the users. For businesses, regular VAPT assessments provide confidence to the users because it shows that the organization is keen on cybersecurity.
Identifying and Mitigating Business Risks
Savings apps are often built onto financial systems, cloud storage and sometimes even databases that could be particularly sensitive. The revenue loss, financial fraud and disruption in business operation can happen from any security flaw. VAPT helps an organization remain proactive in the type of vulnerabilities, assess their impact and then implement required security measures to deal with them.
Preventing Financial and Legal Consequences
The financial losses are explained to be regulatory fines, compensation claims, and lawsuits as a result of a security breach. As a consequence of not securing their mobile applications, companies stand to lose not only their customers but also their competitive edge. However, minimization of such risks and safeguarding business continuity can be achieved through regular VAPT.

Mobile App VAPT Methodologies
Information Gathering
The first part of mobile application VAPT is intelligence gathering of the mobile application’s architecture, functionalities, third party integrations, the backend API’s, and possible attack vectors. In this phase, the testers would understand how the app works and where the vulnerabilities lie. Application permission analysis, dependencies analysis, as security configuration is platform.
Static Application Security Testing (SAST)
SAST in Mobile App VAPT looks at the app’s binary file, source code and configuration files but does not run it. This technique is used to identify vulnerabilities such as hardcoded credentials, insecure data storage, careless encryption, insecure API endpoints, etc. Static analysis is done by tools such as MobSF, APKTool, and Radare2. Aspects covered in SAST include:
- MobSF (Mobile Security Framework) – Detection of insecure coding practices, SQL injection danger, and buffer overflows in the source code.
- APKTool – Hardcoded Secrets Detection by verifying scanned apps includes hardcoded API keys, passwords, encryption keys, etc.
- Frida – AndroidManifest.xml and iOS Plist files Analysis for manifest file security, as well improper components and permissions.
Dynamic Application Security Testing (DAST)
DAST tests the application in runtime to catch the issues associated with the runtime security, authentication and session management. In this technique, it approximates real-world attack conditions to test how the app would respond under varied conditions. Key focus areas include:
- Authentication & Authorization Tests – Bug hunting logic of block and pass logic of authentication and user access control.
- Data Checks – Detecting unintended data exposure via logs, cache and clipboard data, and data leakage testing.
- Runtime API Security – Ensuring that API calls do not contain any bad authentication and authorization control using Burp Suite and ZAP Proxy.
- Burp Suite – For analyzing and testing API security.
- ZAP (Zed Attack Proxy) – An open-source penetration testing tool for web applications.
- Wireshark – Admin Tool to detect and alleviate security faults.
Reverse Engineering
To find out if a compiled application code has security flaws, e.g weak encryption, exposed API keys or debug logs that attackers can exploit, they are reverse engineered. With the help of this technique, vulnerabilities that are not visible through usual testing methods may be identified. Reverse engineering involves the use of some key tools –
- Ghidra – Reverse engineering framework for analyzing compiled code that is powerful.
- Frida – A Dynamic instrumentation toolkit allowing to inject custom scripts into apps at runtime.
- Android APK Exploiter – Used for decompiling Android APKs and inspecting the components inside.
Network Traffic Analysis
APIs are the way for Mobile App VAPT to communicate with remote servers. Network traffic analysis lets you find security problems, such as unencrypted data transmission, API misconfiguration, and man in the middle (MitM) attack vulnerability. Key areas assessed:
- HTTPS Enforcement – Make sure all data exchange is encrypted via TLS to avoid interception.
- API Endpoint Security – Checking for exposed API endpoints and improper authentication mechanisms.
- Session Hijacking Prevention – Identify the flaws that allow the attacker to hijack user sessions.
- Common tools for the interception and analysis of network traffic include Wireshark, Burp Suite, Charles Proxy and so on.
Exploit Testing (Penetration Testing)
Penetration testing consists of actively exploiting vulnerabilities discovered in other testing phases. In the case of an ethical hack, ethical hackers try to break an application’s security defenses by attempting to break the application to assess its real-world risk exposure. Common penetration testing techniques include:
- Privilege Escalation – An attempt to gain a higher privilege by some misconfiguration.
- Injection Attacks – SQL Injection, Command Injection, and Code Injection Attack tests.
- Application logic tampering – Messing up the app features to escape the security filters.
These security test toolkits, such as Metasploit, Drozer, and Frida, help security testers perform in-depth penetration testing.
Reporting and Remediation
Once the security assessment is complete, a full report on all the points of vulnerability, along with their severity levels, possible effects, and recommended fixes, is generated. The report typically includes:
- Vulnerability Description – Explanation of the security flaw.
- Severity Rating – A scale which shows the risk assessment per exploitability and business impact.
- Proof of Concept (PoC) – How the vulnerability can be exploited:
- Remediation Guidelines – Recommended fixes and security best practices.
By taking these approaches, organizations can ensure their mobile applications are more secure, eliminate potential risks and ensure they comply with industry security standards.

Common Mobile Application Vulnerabilities Identified in VAPT
Sensitive Information Storage –
The most problematic part of mobile applications is storing sensitive information, such as authentication tokens and user credentials, in plain text or insecure locations known to everyone. They can provide access to these files, such as through malware or physical access to the device. Android Keystore and iOS Keychain should be used as secure storage mechanisms.
Lack of Authentication & Authorization –
Applications without any authentication stack and relying solely on cookies or database credentials are prone to leakage of both user and database credentials during the primitives to manage authorization. Strong authentication and correct authorization controls should be implemented.
API Access –
Many Mobile App VAPT perform operations involving backend APIs that exchange data. Unauthenticated API, unlimited rate, bad validation can see sensitive data out and a person without right to see it. Token-based authentication, using OAuth and JWT, can be enforced to secure requests to API calls.
Transmission of Unencrypted Data –
Data passing over unsecured channels (HTTP rather than HTTPS) are at risk of man-in-the-middle (MITM) attacks. The data can be intercepted, altered or stolen. This process ensures that the communication is secured by the use of TLS encryption.
Attack Simulation –
The best way to detect compromise, manipulation, and bad actor behavior is through simulation. Reverse engineering should be prevented by code obfuscation, use of anti-debugging techniques and integrity checks.
Poor Session Management –
If the sessions are extended over a longer period, there is a chance that sessions can be hijacked (as long as the token is not invalidated at the end of the session). The absence of a logout functionality or too lax session expiration policies can also turn out to be problematic. This can be mitigated by implementing short session lifetimes and logging out after inactivity.
Malware –
To steal user data or carry out an unauthorized action, attackers can inject malware with Malware Injection if an app allows unverified third-party integrations or has weak code validation. Prevention of this issue is possible through practices of secure coding, input validation, and some app store security reviews.
Security Breaches go Unnoticed –
This occurs in case of lack of proper logging & monitoring. Logging concerning the activities at the security level should be done for mobile applications to indicate suspicious activities and notify the administrators.
Unauthorised Access to Console Logs –
Exposing output such as console.log() from the server layer can also expose data or provide a way for an attacker to pass unnoticed. Sufficient data should be secured with strong industry-standard encryption methods.
