Device Security
An Untrusted Installer is any app you install from outside official sources like third-party websites or unofficial app stores. This includes apps downloaded from third-party websites, unofficial app stores, or modified APKs. These apps can be risky because they might contain harmful code or changes that could affect your device’s security and steal your data.
The app checks for untrusted installers to protect users from security threats like malware, phishing and unauthorized modifications. By verifying the app is installed from a trusted source such as the Google Play Store / Apple App Store, it helps prevent fake versions, tampering or malicious software that could compromise user data and device security.
If the app is identified that it was installed from an untrusted source, you will receive a warning about potential security threats. Depending on the app's security policies, certain actions may be taken such as limiting functionality or disabling specific features until the installation is confirmed as legit. For your safety, we highly recommend reinstalling the app from an official source such as the Google Play Store / Apple App Store to protect your account and device integrity.
To fix it and keep your device safe:

  1. Uninstall the current app.
  2. Reinstall it from an official source:
     • Android: Google Play Store
     • iOS: Apple App Store
  3. Avoid third-party websites or APK files.
  4. Check the app’s legitimacy by looking at the developer name, reviews, and download count.
  5. Make sure the app hasn’t been tampered with by checking for valid security certificates (if shown).
  6. Following these steps helps ensure your app is secure and trustworthy.


Yes, you can still use the app even if an untrusted installer is detected and there will not be any restrictions on its functionality. However, for your safety, we highly recommend uninstalling the app and reinstalling it from an official source like the Google Play Store / Apple App Store to protect the integrity of your account and device.
No, it only affects our app and won’t change your device settings or impact other apps. But apps from untrusted sources can carry risks like malware that may harm your device or compromise other apps. To stay safe, always install apps from trusted sources like the Google Play Store or Apple App Store.
Malware refers to malicious software designed to harm, exploit, or compromise devices, applications and user data.

The RHB Mobile Banking App has a built-in Malware Shielding feature that alerts you to potential threats.

This feature enhances protection against unauthorised transactions and ensures a safer online banking experience by identifying suspicious applications, unauthorised permissions or settings that could expose your personal data to cybercriminals.
You’re seeing this alert because our system found an app on your device that might be unsafe or a security risk. These apps could:
  • Try to access your banking info without permission
  • Steal your login details or OTPs
  • Run secretly in the background
  • Record what you type or see on your screen
  • Let scammers control your device remotely
These alerts serve as a warning that your banking accounts and financial transactions may be at risk. We strongly recommend deleting any suspicious apps to keep your banking safe."
Follow these steps to stay safe:
  1. Check the alert to see which app or setting triggered it.
  2. Delete/uninstall any suspicious apps you don’t recognise or trust.
  3. Turn off risky settings like Developer Mode or Accessibility for unknown apps.
  4. Restart your device to stop any background threats.
  5. Open the app again to see if the issue is fixed.
  6. Keep an eye on your bank account and report anything unusual.
These steps help protect your data and keep your banking secure.
No, for security reasons, access to our app will be blocked until the detected apps are removed from your device.
Follow these steps:
  1. Only download apps from official stores like Google Play or the App Store.
  2. Avoid third-party sites and unofficial app downloads.
  3. Keep your phone and apps updated to patch security gaps.
  4. Check app permissions and only allow what’s necessary.
  5. Don’t click on suspicious links in emails, texts, or social media.

Scammers use sneaky tricks to get you to install harmful apps, such as:
  • Fake ads or promos – They offer tempting deals (like cheap durian or cleaning services) and ask you to download apps from outside the official app stores.
  • Phishing messages – They pretend to be your bank, a delivery company, or even the government, asking you to click a link or install an app.
  • Scare tactics – Pop-ups may claim your phone has a virus and push you to install a fake ""security"" app.
  • Malicious ads – Clicking on infected ads can install malware without you knowing.
  • Fake support calls – Scammers call pretending to be from the bank or tech support and ask you to install an app that lets them control your phone.
To stay safe: Only download apps from the Google Play Store or Apple App Store, and ignore deals or messages that seem too good to be true.
It's a security feature that blocks the app when your screen is being shared to another device (like a TV or computer).

While screen mirroring is useful, scammers can misuse it to steal your banking info through remote access. To keep your financial data safe and private, the RHB app will stop working if screen mirroring is detected.
Using screen sharing, screen recording or screen mirroring while accessing your RHB Mobile Banking App can expose your account to security threats, including:

Exposure of Sensitive Banking Information - Your account number, balance, transaction history and personal details may become visible to others. This information can be exploited for fraud or identity theft.
Unauthorised Access - If you're screen sharing with someone who has malicious intent, they could capture sensitive data or manipulate you into performing actions that compromise your account security.
Data Leakage - Since screen mirroring transmits data to another device, it increases the risk of exposing confidential information, such as login credentials, personal messages and private details, to unintended recipients.

To secure your account and data: The RHB app blocks access when screen mirroring is detected to prevent these risks.
Jailbreaking (iOS) and rooting (Android) are ways to remove the built-in security limits on your device so you can fully control it.
  • Jailbreaking lets iPhone users install apps and make changes that Apple normally doesn’t allow.
  • Rooting gives Android users deep access to system settings and lets them install custom software.
While this gives more control, it also makes your device much less secure and more vulnerable to malware, hacking and data theft.
While it lets you customise your device, jailbreaking (iOS) or rooting (Android) comes with serious risks:
  • Higher risk of malware from unverified apps
  • System issues like crashes or poor performance
  • Weaker security, making it easier for hackers to steal your data
  • No warranty or official support from the manufacturer
  • Possible legal trouble for using apps from unofficial sources
To keep your device safe and secure, it’s best to stick to the official operating system and avoid jailbreaking or rooting.

For your security, the RHB app won’t work on jailbroken (iOS) or rooted (Android) devices. If the app detects these modifications, it'll automatically close to prevent potential risks like malware or unauthorised access to your account.

To use the app safely, please install it on a device that hasn’t been modified.
To use the app, you’ll need to restore your device to its original, secure state:
  1. Remove the jailbreak or root by resetting your device to factory settings.
  2. Update your device to the latest official operating system.
  3. Reinstall the RHB app from the Apple App Store or Google Play Store.
This ensures your device is safe and the app works as intended.
To keep your device safe, follow these steps:
  • Avoid sideloading apps – Only download from the Google Play Store or Apple App Store.
  • Keep your operating system updated – Install the latest security updates.
  • Use a trusted mobile security app – It helps detect and block threats.
  • Don’t click on unknown links – Be careful with links from emails, messages, or social media.
These steps help protect your device from untrusted apps and other security risks.
If a risky app has accessibility permissions, it can:

Control your device remotely
• Steal your banking info by reading what’s on your screen
• Hide signs of malware or fraud


How to turn off unnecessary Accessibility permissions:
  1. Open your device’s Settings
  2. Tap Accessibility
  3. Go to Installed apps and select the app listed in the alert
  4. Turn off the permission
  5. Relaunch the RHB app

Developer mode allows installation of unverified or modified application, increasing the risk of malware infections. Attackers can exploit this mode to bypass security restrictions and compromise sensitive data.
Sharing your screen while using banking or personal apps can expose sensitive details, such as your account info to others. This increases the risk of unauthorised access, phishing, and fraud.
Debugging tools can reveal how an app works behind the scenes. Hackers may use them to find weak spots, steal data, add harmful code, or bypass security features.
Some third-party keyboards may be unsafe. They can track what you type, such as passwords or banking details and send that info to attackers.

To stay safe, it’s best to use your device’s default keyboard.
The RHB Mobile Banking App only works in your device’s main profile. It doesn’t support secure or private folders (such as Samsung Secure Folder or Google Work Profile) because these spaces can interfere with security checks and increase risk.
If the app is installed in environments such as Samsung Secure Folder, Google Private Space, or Work Profile, it will close as soon as you open it. This is a security feature to make sure the app only runs in trusted environments..
It applies to all Android users. The app must run in the main profile, not in any private, secure, or work space. This helps keep your mobile banking experience safe and consistent.
Yes, you can use other apps in those folders. Just make sure the RHB app is installed and used from the main profile so it works properly and stays secure.
These settings can make your device more vulnerable to hacking, malware, malicious apps, remote control or data theft. For your safety, especially when using banking apps, it’s best to keep them turned off.
