Security Advisory: 19 April 2013
Security Alert on Malware in Circulation (19 April 2013)
Dear Valued Client
We would like to bring to your attention that there have been recent reports of new malware attacks on internet banking websites. The malware is designed to take over the login session upon successful authentication of the clients’ login credentials (User ID, Password and One Time Password OTP) by the Bank, followed by attempts to manipulate the client into performing unintended transactions.
The malware is known to be distributed via email in an attached zip file. If clients click on the zip file, their PCs will be infected. We understand that currently the malware cannot be detected by anti-virus software at the point of infection.
If your computer is infected by the malware, these are some possible ways the malware will attempt to steal your login and authorisation information:
- You may receive multiple prompts for login information even when your login information has been entered.
- You may be asked to enter login information on only one page. E.g. The fraudulent screen will ask for your User ID, Password and One Time Password OTP) all on a single page to gain access to your information faster. The normal login process is done over two pages. The legitimate Bank of Singapore website only asks for your User ID and Password on the first page and your One Time Password OTP on the second page.
- You may also be re-directed to a bogus site where your login information will be stolen.
We would like to assure you that our web banking portal remains secure. Please stay vigilant when banking online. You can also take note of the following five tips to protect your computer or mobile device from becoming infected with such malware:
- Install anti-virus software in your computer or mobile device, ensure regular updates of such anti-virus software and scan your computer or mobile device regularly.
- Always type in the URL (http://www.bankofsingapore.com) manually and verify the web banking portal before providing your login information.
- Do not enter any One Time Password OTP for actions that you did not initiate or request.
- Avoid visiting unknown and unsecured websites and avoid downloading unknown mobile applications.
- Do not open unknown or suspicious attachments in emails, even if they are from senders you know.
Please inform your Relationship Manager immediately if you experience difficulty accessing your account after you have entered your credentials or see repeated login pages asking for your login details.
If you suspect that your computer has been infected by the malware, please DO NOT proceed with your online banking activities and follow the steps here.
At Bank of Singapore, protecting your information has always been our priority. To learn more about online security and tips on protecting yourself from fraud, please visit: http://www.bankofsingapore.com/Security03.htm
