UOB Customer Security Advisory Update

Dear customers,

We have implemented additional monitoring and security measures in light of recent industry reports on personal identity thefts, scams and fraudulent activities on credit cards.

While we have various measures to keep your data secure, we would like to remind you to stay vigilant.

Always remember:

  • UOB does not send unsolicited SMS or emails asking customers to click on a link and to enter their personal or account details into a website. If a customer does receive an unsolicited email or SMS which appears to be from UOB, or if they are in doubt, they should call us first before taking any further action.
  •  
  • Do not click on any hyperlinks or provide your UOB card details, userID, PIN or One-Time Passwords and any sensitive information to unverified channels such as websites, emails, survey or callers etc.
  •  
  • Check that you are on a legitimate or secure website. A secure website will have 'https:' at the start of the URL instead of ‘http’. It will also display a closed padlock or unbroken key icon on your browser window. When you click on the icon, a window should also appear to let you know that the website is secure.
  •  
  • To access UOB's website, the safest way is to open your browser and type "https://www.uobgroup.com/" in your browser’s address bar.
  •  
  • Always check your UOB credit card and bank account statements for any unauthorised transactions.
  •  
  • Contact us at 6255 0160 immediately to report any suspicious activities or transactions involving your UOB accounts.

Online Card Transactions

Dear UOB customers,

We would like to inform you of a new malware which targets consumers using Android mobile devices to make online purchases.

This malware infects Android mobile devices and attempts to steal credit card information and SMS One-Time-Password (OTPs) to make online purchases.

 

How does the malware infect your mobile device?

This malware is spread through mobile applications (apps) that are downloaded and installed from unknown sources.

It could infect your phone by prompting you to install apps through fake screens such as those seen below.

 

 

Once you click on the button within the message, you will be directed to enter your credit card information for payment. This will trigger a fake system upgrade (see screenshot below) during which the fraudster will take the opportunity to intercept your SMS OTP and perform online purchases using your credit card information.

 

We would like to assure you that UOB’s online banking systems remain secure and are not the source of this malware. While we take every responsibility to safeguard your transactions with multiple layers of security, we would like to remind you to remain vigilant when banking online.

If you suspect that you have been made a victim of malware or notice unknown transactions appearing on your accounts, please call us immediately at 1-800-222-2121.

What can you do to protect yourself from Malware?

  1. Be alert and cautious. Do not click on any link or button that you do not recognise.
  2. Do not provide payment card information unless you are making a genuine purchase. If you are required to make any payment for mobile application, it should be via Google Play Store.
  3. Do not download or install apps unless they are from authentic sources (such as Google Play Store)
  4. If your mobile phone stalls, immediately shut down the mobile phone and wait for five to 10 minutes before rebooting your phone.
  5. If you continuously get prompted to update your mobile app, ignore it and send your mobile phone for servicing.
  6. If you have unintentionally clicked on an unknown link that triggers a system update, shut down your phone immediately and call your bank to check for any unauthorised online transactions on your debit or credit cards

To enhance the security of e-commerce transactions, you will be required to enter a One-Time Password (OTP) for purchases made at participating 3-Domain Secure (3DS)^ online merchants. This OTP will be sent via SMS to the mobile phone number* of the Principal or Supplementary Cardmember as per our records.

^3-Domain Secure (3DS) protocol is used by banks worldwide to authenticate online card transactions. Cardmembers can recognise the participating 3DS merchants by the Verified-by-Visa, MasterCard's SecureCode, American Express SafeKey or JCB's J/Secure logos on the online merchant's website.
