1. Avoid accessing Internet banking accounts from cyber cafes or shared PCs.
2. After you have logged in, you will not be asked to provide your username and login password again. Also, you will not be asked to provide your CREDIT or DEBIT CARD details while using internet banking. If you get a message (such as through a pop-up) asking for such information, please do not provide this information no matter how ‘genuine’ the page appears to be. Such pop-ups are most likely the result of malwares infecting your computer. Please take immediate steps to disinfect your device.
3. Be aware of downloading any malicious application from mobile application stores (Google Playstore, Apple App Store, Blackberry App World, Ovi Store, Windows Marketplace etc) that are offering Online Banking. Kindly check their authenticity before downloading, by contacting your Bank.
