What we need from you is just the mobile app binaries. At Valency Networks, we believe in mimicking real life hackers. They have access only to your app's binaries and ideally that's all we expect from you. Once we are formally and professionally engaged with you to perform pentesting of your mobile app, we do ask few questions such as below
There are few more questions besides above, which are relevant to your application's business functionality. We map all this to do threat modeling of your application and figure out how to perform the vulnerability assessment and penetration testing.
Once the app is mapped, we employ a very methodical, technical and systematic approach to perform penetration testing. While we use the detailed OWASP-Mobile-Top-10 model, the testing is broadly categorized into static analysis (data at rest) and dynamic analysis (data in transit). Please check this page to know how it is done.
Mobile app penetration testing typically includes "data at rest" and "data in transit" security testing in context of the mobile application. This is true irrespective of whether it is Android app, or iOS app or Windows Phone app. Penetration testing tools are used as part of a penetration test to automate certain tasks, improve testing efficiency and discover issues that might be difficult to find using manual analysis techniques alone.
Two common penetration testing tool types are static analysis tools and dynamic analysis tools.Customers typically expect the app to be security tested end to end. This involves the mobile app binary as well as the backend web services. Manual penetration testing layers human expertise on top of professional penetration testing software and tools, such as automated binary static and automated dynamic analysis, when assessing high assurance applications.
A manual penetration test provides a wider and deeper approach to ensure great deal of accuracy, which is imperative for the hardening of mobile app from malicious attacks. While the vulnerability assessment does the task of finding security problems, the penetration testing proves that those findings actually do exist and shows ways to exploit those. Thus the penetration testing attempts to exploit security vulnerabilities and weaknesses of the app throughout the environment, attempting to penetrate both at the network level and key applications.
With the increased use of mobile phones and tablets, many applications are now hosted on Google Play and Apple iTunes for user convenience. Users store more than just photos and messages on their smartphones, making mobile app security critical and necessary. Applications that deal with users' critical data, such as finance, health, and investments, must ensure their mobile application is secure in order to avoid privacy issues and data breach incidents, which can have serious consequences.
Valency Networks employs a technical and systematic approach to mobile app security testing. The process begins with decompiling and detailed analysis of data at rest, followed by identifying data in transit vulnerabilities.
The OWASP Mobile Top 10 model is used in the mobile application penetration testing methodology to ensure that all angles of security threat vectors are tested. Valency Networks is known to be one of the top VAPT services company as it uses an integrated approach to identify security risks before they are exploited, combining the strengths of manual penetration testing, jail breaking technology, and mobile platform appropriate tools.
For mobile applications, OWASP has developed separate guidelines and attack vectors. Along with which we also have our own test cases and checklists pertaining to the application business logic. Because mobile apps include both static and dynamic code analysis, it is critical to cover these angles with a carefully crafted vulnerability assessment checklist. OWASP TOP 10 Mobile security issues have been listed below:
This issue includes exploiting platform features or bypassing security controls on the platform. This may involve intent, permissions, TouchID abuse, or any other security feature of a mobile OS.
The development teams assume that users or malware won't have access to a mobile device's filesystem and, consequently, store sensitive data in data-stores of the device, leading to insecure data storage problems. This can result in the loss of data of a user or, in worst-case scenario, of multiple users.
Mobile applications frequently have trouble safeguarding network traffic. SSL/TLS may be used during authentication but not elsewhere. This inconsistency raises the likelihood of data and session IDs being disclosed.
One of the root causes of many security risks is poor authentication. Examples of Insecure authentication attacks include authentication bypass, information disclosure via debug messages, and session invalidation.
The process of converting plain text data into an unreadable form is known as cryptography. Most developers ignore cryptography because it is difficult to implement, whereas cyber-criminals or hackers take full advantage of it.
Several mobile applications have insufficient permission, allowing low-level users to access information belonging to any high-level user. This introduces a variety of business-level problems.
Ensuring code quality is critical while developing mobile applications. Buffer overflow, cross-site scripting, and blind XSS attacks occur as a result of poor code quality, which leads to unsafe design.
Code tampering is a technique in which hackers or attackers make code alteration through malicious versions of softwares published in third-party app stores accessible over the internet.
Reverse engineering is the process of decompiling a mobile application in order to understand its logic. Code obfuscation is used to prevent attackers from reading the application code and understanding the logic.
Cybercriminals or hackers, attempt to comprehend the additional functions of the mobile application. The primary purpose is to understand and investigate the backend framework's underlying functions.
We also follow our expert's checklist on Mobile applications security for manual testing. Manual testing helps in digging deep into the application and it functionalities to find security vulnerabilities. Find more about this :
We support following frameworks while pentesting a mobile app:
Mobile Internet usage has exceeded fixed Internet access. This is primarily due to the expansion of hybrid and HTML5 mobile applications. Application servers, which serve as the foundation for these applications, must be secured on their own.
A complete compromise of the application server may be caused by flaws like injections, unsecured direct object references, insecure communication, and others. Once hackers have taken control of the compromised servers, they can push malicious content to all application users while also compromising user devices.
As the name implies, Insecure Data Storage is concerned with the security of data in storage. Mobile applications are used for a wide range of tasks, including gaming, fitness tracking, online banking, stock trading, and so on, and the majority of the data used by these applications is stored on the device itself in SQLite files, XML data stores, log files, and so on. Alternatively, they are sent to cloud storage.
These applications may store sensitive data ranging from location information to bank account information. Application programming interfaces (APIs) that handle storage of data must use encryption algorithms so that a malicious user with direct access to these data stores through theft or malware is unable to decipher the sensitive information stored in them.
All hybrid and HTML 5 apps use a client-server architecture, with an emphasis on data in motion because the data must travel through various channels and is vulnerable to eavesdropping and tampering by hackers. SSL/TLS controls, which enforce data confidentiality and integrity, must be verified for proper deployments on the communication channel between the mobile apps and its server.
Certain mobile application modules may store sensitive user data in areas where it can be accessed by other applications or even malware. These features may be present to improve usability or user experience, but they may have negative long-term consequences.
Malicious actors can use actions such as OS data caching, key press logging, copy/paste buffer caching, and implementations of web beacons or analytics cookies for advertisement delivery to obtain information about victims.
Because mobile devices are the most personal devices, developers take advantage of this by storing critical data such as credentials locally on the device and developing specific mechanisms to authenticate and authorize users locally for the services that the user is requesting via the application.
If these mechanisms are not well developed, hackers may be capable of bypassing these controls and perform unauthorized actions. Because the code is available, they can perform binary attacks and recompile it to directly access authorized content.
This relates to ineffective data protection controls. The use of weak cryptographic algorithms that can be cracked, such as RC2, MD5, and others, will result in encryption failure.
Poor encryption key management, such as storing the key in locations accessible to other apps, or the use of a guessable key generation process, will also cause the cryptographic approaches to fail.
Injection vulnerabilities are caused by faulty inputs, which result in unwanted events such as database query changes, command execution, and so on. Malformed inputs in mobile applications can pose a major hazard both at the local application level and on the server side.
Injections at the local application level, which primarily target data stores, may result in problems such as access to premium material that is restricted to trial users or file inclusions, which may lead to the abuse of functionalities such as Messaging.
Some functionalities, such as the use of hidden variables to check authorization status, can be bypassed by interfering with them during transit via web service calls or inter-process communication calls. This may result in privilege escalation and undesired mobile application behavior.
On successful authentication with the mobile application, the application server returns the session token. These session tokens are utilized by mobile applications to make service requests.
If these session tokens remain active for an extended period of time and attackers can obtain them through malware or theft, and the user account can be compromised.
Everyone has access to the source code for mobile applications. An attacker can reverse engineer the application and install malicious code components, which are then recompiled.
If a user installs this altered software, they will be vulnerable to data theft and become victims of unwanted activities. Most apps do not have features such as checksum controls, which aid in determining whether or not the application has been tampered with or not.
Android apps are fragile if care is not taken properly. The same goes with iOS because it's taken for granted to be secure by nature. Our years of experience in android and iOS operating system bases and the API's helps us device the platform specific checks which range into hundreds of vulnerability possibilities each. All operating systems give out logs, which we capture too, to figure out data leakage possibilities.
An important step in mobile app pentesting (VAPT) is to decompile the app. This helps us get under the skin of the app to expose the code. We deep dive into the code modules to find whether or not the coding is done to achieve the security, especially against data privacy thefts. This makes us a unique and best mobile app VAPT company, providing VAPT services to customers from all industry sectors.
By capturing the traffic originating from the mobile app, towards the backend cloud or web hosted services. We look for possible injections into that traffic at various parameters. SQL Injection, cookie injection, script injection are few examples of it.
A - Each application stores data on the mobile device in some form or other. The locations can also be different, ranging from the device memory to the external storage. We detect this and see if/how that data can result into potential critical information leakage. Encryption is one of the things that we test, but there are many complex security scenarios (especially in android), that we test the vulnerabilities for.
Yes. If the application is not hosted, the mobile application apk or ipa can be shared. Pentesting the mobile application using the apk or ipa file won't be a challenge.
Mobile app security testing is to be carried out before deployment of the application and every time a new functionality or feature is added. Other than that, quarterly or half yearly VAPT/security testing need to be done on the mobile application to ensure the application is secure against the daily emerging new attacks and techniques.
