Beware of Android Phone Malware

Please beware of Android Phone Malware targeting Credit Card online purchases

Currently, there is a new “malicious software” (malware) targeting consumers using Android smartphones, and we would like to remind you to be careful when performing online credit card transaction in order to avoid becoming a victim.

This malware works by spreading through mobile applications that are downloaded and installed from unreliable sources. Once they are downloaded onto your smartphone, the malware will attempt to access your credit card information. Then, it will use your credit card information to make online purchases, and block the SMS One-Time-Password (OTPs) to your smartphone so that these online purchases can be completed.

The screenshots below are examples of how the smartphone can be infected by the malware.

You would receive a message via WhatsApp (or LINE) about the application updates or expiry from untrusted sources which resulted in malware being installed on smartphones

Then, the malware will show a fake system upgrade screen (see screenshot below) to prevent user from seeing the SMS OTP (while blocking the SMS OTP), so that the fraudster would successfully make the online purchases.

What can you do to protect yourself from the Malware:


  1. Do not click on any button or hyperlinks from messages and emails if you are unsure of the source.
  2. Do not download apps from unreliable websites, since the apps may bring risks of malwares. Only download or install apps from only trusted sources (such as the Google Play Store).
  3. Do not jailbreak your phone’s operating system, since it makes your phone more susceptible to malware.
  4. Do not provide credit card information unless you are making a purchase on your own. If it is necessary to make any payment for Android mobile application, it should be made only to trusted sources
  1. Be cautious if a screen on your smartphone suddenly pops up and asks for your confidential information such as your credit card, especially if you did not initiate any related activity.
  2. Update the operating system of your phone regularly, since these updates will be able to fix problems and provide new features for better protection.
  3. Install anti-malware application from trusted sources. These anti-malware apps normally are able to detect and remove malware.
  4. Set a password for your smartphone use in order to prevent any authorized use.
