As part of our ongoing efforts against cybercrime and to protect your online banking experience, we introduced an essential security feature to the OCBC Digital app.

The latest versions of the OCBC Digital app on Android are built to work more optimally and securely on devices whose mobile apps were all downloaded from official app stores (e.g. Google Play Store or Huawei AppGallery). Such apps are verified before they are made available for downloading. Apps from other sources (e.g. official brand websites or apps installed using Android Package Kit (APK) files) are not verified. They tend to have more security vulnerabilities and so are more susceptible to malware infection, which can allow cybercriminals to gain control of your device and, subsequently, your banking app(s) and personal details.

This inherent risk in apps downloaded from sources other than official app stores has been reiterated by Singaporean authorities, who classify malware scams as particularly aggressive and a serious threat to consumers. Despite constant reminders by the authorities of the dangers of downloading these apps, the number of customers falling prey to malware scams has continued to increase.

If you try to access the latest OCBC Digital app on a device which has apps downloaded from sources other than an official app store, a message – warning you that one or more apps on your device may contain malware – will pop up on the screen. We recommend that you uninstall such apps before continuing to use the OCBC Digital app securely. You do not have to delete the OCBC Digital app.

Alternatively, if you prefer to keep these apps after having assessed that they are not malicious and do not pose a malware risk, you may turn off ‘Accessibility’ for these apps before continuing to use the OCBC Digital app securely. You can do so via the Settings menu on your device. For example, on Samsung mobile devices with the latest One UI user interface, you can navigate to Settings > Accessibility > Installed Apps*.

Turning off 'Accessibility' will cut off scammers’ remote access to, or keylogging of, your phone and any access to your bank account(s). However, we do not recommend this option because of the residual risk – cybercriminals may still exploit ‘Accessibility’ services to compromise your devices. The preferred and safer option is to uninstall apps not downloaded from official app stores to completely remove the risk of malware from such apps.

*The steps to turn off an app’s ‘Accessibility’ may differ by phone model. Please refer to question 7 or check with your device manufacturer.

FAQs

1. When I open the OCBC Digital app, I see a pop-up message informing me that one of more apps on my device may contain malware. Why?

As part of our efforts to safeguard our customers against malware attacks, and combat fraud and scams, we have introduced an essential security feature for the OCBC Digital app.

The OCBC Digital app will now work more securely on devices whose mobile apps were all downloaded from official app stores. Malware attacks may emerge from apps that are downloaded from websites and other sources (i.e. not official app stores), potentially giving cybercriminals control of your devices.

The pop-up message is meant to inform you that the OCBC Digital app will not work until you uninstall one or more apps not downloaded from an official app store (this is the preferred option), or until you turn off ‘Accessibility’ for these apps.

Here is what the pop-up message looks like:

2. Do I have to install the OCBC Digital app again when I see the pop-up message?

You do not have to delete, download, or do anything to the OCBC Digital app. Instead, please uninstall the apps shown in the pop-up message to continue using the OCBC Digital app or turn off ‘Accessibility’ for those apps.

3. Will the Bank know what other apps I have on my device through this security feature?

We take privacy seriously. We do not monitor customers’ phone activity or conduct surveillance on customers’ phones. The new security feature does not collect or store any personal data; neither will it identify the owner of the device. We do not collect or store information on how our customers use apps installed on their mobile device.

Instead, an additional security check is simply performed directly at the device level. This means that no information or data will be transmitted back to us. The information collected at the device level is only used to identify if certain security parameters are not met. These parameters include apps residing on a device which were not downloaded from an official app store, and which have ‘Accessibility’ turned on. Apps with ‘Accessibility’ turned on can render your device more vulnerable to exploitation by hackers, scammers and other bad faith actors using malware.

We apologise for the inconvenience caused and seek your understanding that the security feature was implemented to protect our customers from malware or suspected malicious apps. Please refer to our article on malware for more information on how you can protect yourself.

4. I want to continue using my OCBC Digital app alongside these apps. Is it possible for you to remove this control?

This security feature was implemented with the intent of protecting our customers from malware and suspected malicious apps. If you wish to continue using your OCBC Digital app alongside apps that are downloaded from websites and other sources (i.e. not official app stores), you may turn off ‘Accessibility’ for such apps.

Please refer to our article on malware for more information on protecting yourself.

5. I want to continue using my OCBC Digital app. What can I do?

To continue using your OCBC Digital app securely, we recommend that you follow these steps:
1. Uninstall the app(s) shown in the message that pops up on your screen when you open your OCBC Digital app.
2. Log in to the OCBC Digital app to ensure that it works.
3. Once you confirm that the OCBC Digital app works, you can try to download the app(s) you deleted from an official app store (e.g. Google Play Store, Samsung Galaxy Store, Huawei Store).

Alternatively, you can turn off the listed apps’ ‘Accessibility’ via the Settings menu on your device. For example, on Samsung mobile devices with the latest One UI user interface, you can navigate to Settings > Accessibility > Installed apps*.

*The steps to turn off an app’s ‘Accessibility’ may differ by phone model. Please refer to question 7 or check with your device manufacturer.

6. What are ‘Accessibility’ services and how do criminals exploit them?

Accessibility services, like text-to-speech and speech recognition, are designed to make technology easier to use. For these services to work, advanced Android system permissions have to be granted to the app requesting them, such as allowing the app to read the text on the device’s screen or record text typed using the device’s keyboard. The latter, for instance, could be used to record your online banking login details.

7. How do I change the Accessibility settings for the third-party apps that I have downloaded?

The path to changing Accessibility settings may differ by device manufacturer and operating system.

Here are the possible paths for some popular phone models. If you continue to face difficulties with changing the Accessibility settings, please check with your device manufacturer.

Samsung Galaxy A53 5G / Flip 4 / Fold4 / A73 5G / S21 Ultra / A23 5G: Settings > Accessibility > Installed Apps

Samsung Galaxy S21 5G / Galaxy S10: Settings > Accessibility > Installed Services

Oppo A78 5G / Reno8 5G: Settings > Additional Settings > Accessibility

Oppo Find X2 Pro / A17: Settings > System Settings > Accessibility

Huawei P50 Pro: Settings > Accessibility features > Accessibility > Installed Services

Huawei Nova 3i / Nova 5T: Settings > Smart Assistance > Accessibility

Huawei Mate30 & Huawei Y9a: Settings > Accessibility features > Accessibility (Scroll down to Downloaded Services)

Google Pixel 5 / Pixel 3 XL: Settings > Accessibility

Redmi Note 10 5G: Settings > Additional Settings > Accessibility > Downloaded Apps

Poco X5 5G: Settings > Additional Settings > Accessibility > Downloaded Apps

8. Why are some well-known apps being flagged by the OCBC Digital app?

This security feature flags apps that have been downloaded from sources other than official app stores. You may have downloaded them from websites or other sources. If you need to continue using these apps, we advise you to first uninstall them. After taking the steps listed in question 5, you can then download and install the most up-to-date version of the app(s) from an official app store (this is the preferred option).

Alternatively, if you prefer to keep these apps after having assessed that they are not malicious and do not pose a malware risk, you will be given the option to continue using the OCBC Digital app after turning off ‘Accessibility’ for these apps – via the Settings menu on your device (e.g. on Samsung mobile devices with the latest One UI user interface, you can navigate to Settings > Accessibility > Installed Apps). This step will help to prevent your device – and OCBC account(s) – from being controlled by cybercriminals looking to exploit potential vulnerabilities in these apps (because ‘Accessibility’ is turned on).

We apologise for the inconvenience caused. The security feature was implemented to protect our customers from malware or suspected malicious apps. Should you require further assistance, please provide more information to us via our OCBC customer feedback form.

9. Where can I read more about how malware may infect my mobile device?

You may refer to the joint advisory issued by the Singapore Police Force and Cyber Security Agency on how malware may infect your mobile device through the downloading of apps that are not found on official app stores.

10. What are the official app stores?

The list includes:
• Google Play Store
• Samsung Galaxy Store
• Huawei AppGallery
• Xiaomi MI App Store
• Amazon appstore
• Vivo V-Appstore
• Oppo App Market

11. When I open the OCBC app, I see a message informing me that USB/wireless debugging has been detected. Why?

As part of our efforts to safeguard our customers against malware attacks, and combat fraud and scams, we have introduced an essential security feature for the OCBC app (applicable to Android devices).

If you see the message, we have detected that USB/wireless debugging (under ‘Developer options’) has been enabled on your Android device. Having these developer options enabled could potentially allow another person to monitor and control your device remotely, making it possible for them to steal your information.

The OCBC app will not work until you have disabled both USB and wireless debugging.

12. Why do I have to disable USB and wireless debugging?

Developer options such as USB and wireless debugging can be exploited by third parties. If these options are enabled, a third party could monitor and control your device remotely to steal your online banking details.

13. How do I disable USB and wireless debugging?

Go to Settings > Developer Options, then toggle off ‘USB debugging’ and ‘Wireless debugging’.

14. Why I am not able to locate ‘Developer Options’ on my device?

Developer Options are likely disabled on your device. If you do not see the ‘USB and/or wireless debugging detected’ message, you do not need to take any action.

What is the OCBC kill switch?

The kill switch enables OCBC customers to immediately freeze all their current and savings accounts (including joint accounts), ATM access, debit and credit cards and digital banking if they suspect they are a victim of a scam or if they believe key account-related details have been otherwise compromised.

Once the kill switch is activated, no transactions – whether done digitally, via an ATM or at branches – can be made. Even recurring or pre-arranged fund transfers will be disabled.

How it works

Customers can activate the kill switch by calling 1800 363 3333 (+65 6363 3333 if calling from overseas) and selecting option ‘8’.

It can also be activated via the OCBC app and at selected OCBC ATMs.

The kill switch will suspend all accounts and the following services:

• Cash withdrawals and deposits (including salary crediting)
• Local and overseas funds transfers, both incoming and outgoing
• Bill payments
• GIRO transactions, both incoming and outgoing
• NETS payments
• Visa and Mastercard payments made using ATM/credit/debit cards in stores and online
• Digital banking transactions

One of our Customer Service Executives will contact the customer after the kill switch is activated to remove compromised bank account access or cards, and issue new ones. Only a bank branch employee or Customer Service Executive can deactivate the switch – and would only do so after receiving duly verified instructions from the customer. Once the kill switch is deactivated, the customer’s account will return to ‘normal’ and all settings prior to the account suspension – including GIRO arrangements and future-dated funds transfers – will be reinstated.

Step-by-step guide to activating the kill switch

To activate the kill switch and temporarily suspend their account(s), customers can use any of these three methods: Call our Personal Banking hotline, go to selected OCBC ATMs or use the OCBC app.
