How to Prevent SSL Cookie Hijacking in Android & iOS Apps

Last updated September 24, 2024 by Appdome

Learn to Prevent Cookie Hijacking in Mobile apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is Cookie Hijacking?

SSL or HTTP cookies are small packets of data stored in your app or browser that are used to facilitate accessing websites or logging into remote services (such as a mobile bank account). Cookies usually contain sensitive data like passwords or user information and is therefore vulnerable to attacks. Cookie hijacking is an attack method used by hackers to access cookies that belong to legitimate mobile users, usually for purposes of impersonating the user, accessing their account, conducting account takeovers (ATO), intercepting communications sessions, or other malicious reasons.

When cookies are generated, they can only be viewed by you – the site owner. No other website can view your cookies. But these cookies travel across the internet. They are used by ad services and analytics services, so they bounce around from server to server all across the globe. If the connection is not secure, a hacker can easily intercept or access the cookies as part of a mobile man-in-the-middle (MITM attack).

One of the most common ways hackers steal cookies is if they are using the same wifi as you. This kind of wifi hacking is called man-in-the-middle attack and can take place only if both are connected to the same wireless network. This can also happen to users within the same computer networks.

Why Prevent Cookie Hijacking in Mobile Apps?

Hijacking cookies is just as powerful (sometimes more so) than stealing a user’s password. It’s possible that with cookie hijacking, hackers can gain unlimited access to all of your resources. For example, an attacker may steal your identity or confidential company data; purchase items; or steal from your bank account.

A cookie attack is often initiated when an attacker sends a user a fake login. The victim clicks the fake link, which lets the attacker steal the cookie – actually, anything the user types in can be captured by the attacker. The attacker then puts that cookie in their browser and is able to impersonate the legitimate user.

Sometimes, a fake link isn’t even needed. If a user is in a session on an unsecured, public Wi-Fi connection, hackers can easily steal the data traveling through the connection. This can happen even if the site is secure and your username and password are encrypted.

Appdome detects, prohibits, and protects app connections against cookie hijacking by validating the server SSL certificate chain’s authenticity and providing authenticity proof to the server on behalf of the client.

Prerequisites for Using Prevent Cookie Hijacking:

To use Appdome’s mobile app security build system to Prevent Cookie Hijacking , you’ll need:

Appdome account (create a free Appdome account here)
A license for Pin to Host/MiTM Prevention
Mobile App (.ipa for iOS, or .apk or .aab for Android)
Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)

Prevent Cookie Hijacking on Mobile apps using Appdome

On Appdome, follow these simple steps to create self-defending Mobile Apps that Prevent Cookie Hijacking without an SDK or gateway:

Upload the Mobile App to Appdome.
1. Upload an app to Appdome’s Mobile App Security Build System
2. Upload Method: Appdome Console or DEV-API
3. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
4. Prevent Cookie Hijacking Compatible With: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more
Build the feature: Prevent Cookie Hijacking.
1. Building Prevent Cookie Hijacking by using Appdome’s DEV-API:
  1. Create and name the Fusion Set (security template) that will contain the Prevent Cookie Hijacking feature as shown below:
  2. Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Prevent Cookie Hijacking feature via Appdome Console, to add the Prevent Cookie Hijacking feature to this Fusion Set.
  3. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below):
    
    Figure 2: Fusion Set Detail Summary
    Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).
  4. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Circle CI or other system:
    
    Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
    
    Look for sample APIs in Appdome’s GitHub Repository
2. Building the Prevent Cookie Hijacking feature via Appdome Console
  
  To build the Prevent Cookie Hijacking protection by using Appdome Console, follow the instructions below.
  1. Where: Inside the Appdome Console, go to Build > Security Tab > Secure Communication section.
    Like all other options in ONEShield™, Prevent Cookie Hijacking is turned on by default, as shown below:
    Figure 3: Prevent Cookie Hijacking option
    Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.
  2. When you enable MiTM Prevention you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Prevent Cookie Hijacking
    
    Figure 4: Fusion Set that displays the newly added Prevent Cookie Hijacking protection
  3. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Prevent Cookie Hijacking:
    
    Threat-Events™ OFF > In-App Defense
    If the Threat-Events™ setting is cleared (not selected). Appdome will detect and defend the user and app by enforcing Prevent Cookie Hijacking.
    
    Threat-Events™ ON > In-App Detection
    When this setting is used, Appdome detects a cookie hijacking attempt and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing, enforcement, and user notification. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Prevent Cookie Hijacking Intelligence and Control in Mobile Apps.
    
    Threat-Events™ ON > In-App Defense
    When this setting is used, Appdome detects and defends against Cookie Hijacking (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence the app’s business logic for processing. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Prevent Cookie Hijacking Intelligence and Control in Mobile Apps.
  4. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
Congratulations! The Prevent Cookie Hijacking protection is now added to the mobile app
Certify the Prevent Cookie Hijacking feature in Mobile Apps

After building Prevent Cookie Hijacking, Appdome generates a Certified Secure™ certificate to guarantee that the Prevent Cookie Hijacking protection has been added and is protecting the app. To verify that the Prevent Cookie Hijacking protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:

Figure 5: Certified Secure™ certificate

Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Prevent Cookie Hijacking has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Prevent Cookie Hijacking and other mobile app security features are in each build of the mobile app
