How can hackers exploit this vulnerability?
1. Hardcoded credentials
Hardcoded passwords, also called embedded credentials, are plain text passwords and other confidential information in the source code.
2. Insecure storage of credentialsStoring user credentials locally on the device exposes sensitive information.
3. Weak password policiesSimple passwords and lack of complexity make it easier for hackers to guess or crack passwords through brute force attacks.
4. Inadequate encryptionTransmitting credentials without proper encryption also exposes sensitive information to be exploited during data transmission.
5. Insecure authenticationIf multi-factor authentication is not in place, attackers can easily gain access using compromised passwords.
6. No session managementIf sessions don’t expire after inactivity, it might expose users to session hijacking and other related attacks.
How can this vulnerability be prevented?
You can fortify your app by:
1. Implementing robust encryption
Encryption is one of the basic principles of mobile security. Ensure that sensitive data, including credentials, is transmitted and stored using robust encryption methods.
2. Enforcing strong password policiesStrong passwords require users to create and update complex and unique passwords regularly.
3. Enforcing secure authentication methodsImplementing multi-factor and two-factor authentication (2FA) will add an extra layer of security.
4. Improving session managementImplement secure session management practices - session expiry after a brief period of inactivity.
2. Inadequate supply chain security
This vulnerability focuses on the activities involved in building and distributing the application. Hackers can exploit vulnerabilities in third-party libraries to access the server backend, manipulate sensitive data, and carry out denial-of-service attacks.

How can hackers exploit this vulnerability?
1. Vulnerabilities
Flaws in third-party applications' source code, such as a lack of data validation or buffer overflow attacks, can create exploitable vulnerabilities.
2. Insecure integration
If the integration between the third-party app and your IT resources is not secure, it might expose you to attackers. Plugins, connectors, and extensions can contain innate security vulnerabilities.
3. Insecure data management
If the app you integrate doesn’t encrypt the data you upload, it makes it easy for attackers to access your private data.
4. Misconfigured access controls
Weak access controls within third-party software that connects to your business can give attackers access to your entire IT infrastructure.
5. Compromised build environment
Attackers can infiltrate the build environment used for compiling and packing your app.
6. Trojanized app release
The compromised build environment can lead to the release of a trojanized version of your app. Your customers may download this version assuming it to be a legitimate version.
7. Malicious code injection
Once inside your build environment, attackers can inject malicious code into the app source code and execute unauthorized actions.
How can this vulnerability be prevented?
1. Code signing and integrity checks
Implement regular integrity checks and code signing to detect unauthorized modifications to the source code.
2. Dependency scanning
Regularly conduct SBOM security analysis and update dependencies used in the application. SBOM is a collection of all components in a software’s codebase.
With Appknox’s SBOM solution, you can track and identify vulnerabilities in your entire software with just one upload.
3. Secure build environment
Regularly update and patch all build infrastructure components to prevent and minimize vulnerabilities.

How can hackers exploit this vulnerability?
1. Insecure value comparisonsInsecure value comparisons in PHP & JavaScript can lead to vulnerabilities. Loose comparisons like == can allow bypassing authentication.
Use strict comparisons with the === operator or dedicated comparison functions to mitigate.
2. Path-based authenticationAuth bypass risks arise when access control relies on path comparison. Attackers exploit parsing inconsistencies to traverse directories.
Input sanitization is crucial to prevent such vulnerabilities.
3. Implicit trust in authentication sourcesIn complex architectures, auth responsibilities may shift, leaving the back end vulnerable to API path traversal exploits and exposing sensitive data.
4. Missing function-level accessIdeally, each query should only return data the user can access.
But this is easy to forget, and any error at any stage allows users unauthorized access to sensitive information. This is common when adding a GraphQL layer to an existing REST API.
5. Token mismanagementIf attackers obtain a valid access token, such as a session cookie, they could hijack sessions, especially with intricate single sign-on setups. Misconfigurations might enable intercepting tokens via redirects or reading them from server logs.
How can this vulnerability be prevented?
1. Implementing token-based authentication
Generate a unique token and validate it for each user session.
2. Role-based access control (RBAC)Define and enforce user roles and permissions.
3. Add multi-factor authenticationThis will require users to provide multiple forms of identification, such as passwords, OTPs, and/or biometric data.
4. Avoid insecure design patternsInsecure design patterns can be avoided by diligently planning threat modeling, proactive vulnerability management, tried-and-true architectural patterns, and SDLC.
4. Insufficient input/ output validation
Applications that do not perform sufficient data validation, risk SQL injection, common injection, or cross-site scripting attacks are vulnerable to this threat.

How can hackers exploit this vulnerability?
Insufficient input/output validation arises when it needs to validate and sanitize user inputs and outputs effectively. In essence, if the app doesn't rigorously inspect and filter the data it receives from users and returns to them, it becomes susceptible to various attacks.
How can this vulnerability be prevented?
1. Input validation
Enforce strict input validation by clearly defining and adhering to appropriate data formats. Employ input validation libraries and frameworks to detect and filter out malicious inputs automatically.
2. Parameterized queriesThese are SQL queries in which placeholders are used for input values rather than directly inserting the values into the query string. The placeholders are then replaced with the actual values using query execution, helping prevent SQL injection.
3. Output encodingEncode or escape potentially dangerous characters in the application's output before sending it to the user’s browser. This prevents attackers from injecting malicious scripts or content into web pages.
4. Data whitelistingIt involves specifying acceptable data inputs, allowing only approved values. Data whitelisting filters user inputs, permitting only predefined values and enhancing security.
5. Insecure communication
This vulnerability commonly occurs in mobile apps interacting with servers and external services. Without robust encryption and security measures like TLS/ SSL, attackers can exploit these weaknesses through eavesdropping and man-in-the-middle attacks, compromising data integrity and confidentiality.

8. Outdated software and patch managementIf regular updates and patches are not conducted, the system could be exposed to vulnerabilities that hackers can exploit.
How can this vulnerability be prevented?
1. Adopt secure coding practicesTrain your developers on secure coding practices and regularly conduct code reviews and static code analysis to identify and remediate security flaws in the source code.
2. Implement data minimization and anonymization techniquesAdopt data minimization principles to collect and retain only the minimum necessary data. Data anonymization helps to anonymize sensitive data through tokenization and hashing to reduce exposure in case of a breach.
3. Deploy intrusion detection and prevention systems (IDPS)Install and configure IDPS to monitor network traffic and detect unauthorized access or malicious activities. Integrating IDPS with centralized logging and monitoring systems helps provide comprehensive visibility into security events and incidents.
4. Implement strong access controls and authentication mechanismsImplement centralized identity management solutions to streamline the organization's user authentication and authorization processes.
5. Encrypt sensitive data at rest and transitImplement robust encryption algorithms (eg, AES-256) to encrypt sensitive data stored on servers, databases, and storage devices.
7. Insufficient binary protections
This vulnerability exposes the application to a spectrum of risks, potentially compromising the confidentiality, integrity, and availability of the application.

How can hackers exploit this vulnerability?
1. Buffer overflow attacksWithout proper protections like stack canaries or address space layout randomization, hackers can overwrite crucial data, inject malicious code, and gain control of the program’s execution flow.
2. Return-oriented programming (ROP)Insufficient protections, such as a non-executable stack or data execution prevention, make it easier for attackers to construct ROP chains, bypass security mechanisms, and execute arbitrary code.
3. Format string vulnerabilityThe lack of format string protections enables hackers to manipulate memory content, leak sensitive information, or overwrite data.
4. Heap exploitationHeap spraying, double-free vulnerabilities, and/or use-after-free can be leveraged to corrupt heap data structure, manipulate memory allocations, and execute arbitrary code.
5.Integer overflow/underflowWithout checks, attackers can manipulate integer calculations to control program behavior.
6. DLL injectionsHackers can inject rogue DLLs into the process address space without checks, enabling them to hijack program execution.
7. ROP gadgets in code reuse attacksWithout control flow integrity, attacks can bypass control flow restrictions and achieve arbitrary code execution using ROP chains.
How can this vulnerability be prevented?
1. Code obfuscation
It obscures program logic and structure by adding complexity, making reverse engineering and exploitation challenging.
2. Binary hardeningIt applies techniques such as stack canaries, Address Space Layout Randomization (ASLR), Data Execution Prevention (DEP), and control flow integrity.
8. Security misconfigurations
Common security misconfigurations occur as a result of leaving default settings unchanged. These are considered the top cloud vulnerabilities.

How can hackers exploit this vulnerability?
1. Default credential exploitation
Hackers can easily search for devices or systems with default credentials and exploit such devices.
2. Unprotected services and portsHackers can scan for open ports and services using tools like Nmap and exploit them to gain unauthorized access.
3. Improper file permissionsAttackers can upload malicious scripts to compromise the system if a web server is misconfigured to allow read or write access to critical system files.
How can this vulnerability be prevented?
1. Centralized configuration managementUtilize centralized configuration management tools to manage and enforce security configurations across multiple systems.
2. Network segmentation and firewallsIsolate critical systems and sensitive data from less secure network parts.
3. Implement the least privilege principleGrant users and processes only the minimum level of access required to keep things running smoothly.
9. Insecure data storage
Device file systems are no longer contained within a sandboxed environment, and rooting or jailbreaking often bypasses existing protections. Not storing data properly will open your systems to vulnerabilities.
Insecure data storage vulnerabilities occur when developers assume that malicious actors will not have access to your file systems and sensitive information.
However, filesystems are easily accessible. Poor encryption libraries make it easy for malicious actors to view application data via rooting or jailbreaking techniques.
In mobile development, data leaks are most seen in undocumented or under-documented internal processes such as:
- How does the OS cache data, key presses, logging, and buffers?
- How the development framework caches data, images, key presses, logging, and buffers?
- The way or amount of data ad, analytic, social, or enablement frameworks cache data, images, key-presses, logging, and buffers.
