Types of online threats

Phishing is an attempt to acquire your financial information via email by pretending to be a trustworthy entity. This includes emails from what appears to be your bank and contains links requesting you to ‘verify your account’ or ‘confirm your billing information’. If you reveal your password, the attacker can access and use your account .
Vishing is similar to phishing, but the medium used is the mobile phone. For example, an automated recording informs you that your bank account has had unusual activity and that you should call a particular number immediately. When you dial the number, you are requested to enter your account details on your keypad.
Smishing (SMS phishing) is a type of phishing attack where you receive text messages on your mobile phone with a link to a website. As soon as you click on the link, it redirects you to a fraudulent website in an attempt to obtain your online banking credentials.

How to secure your mobile phone

CBD Mobile Banking Apps Security

CBD Mobile Banking Apps use various security measures and data encryption to ensure your day to day banking is completely safe with a User ID/Password, PIN and security token  for high level transactions. Some of these security measures are:

  • Personalised activation/registration process with unique one time password code
  • Secure registration process using CBD Online Banking credentials
  • Multilevel checks using personal password/PIN or security token

The ability to control your beneficiaries by adding or removing utility bills, internal and external payments details through synchronisation from CBD Online Banking through receiving an OTP (one time password) notification on your mobile.

Mobile security tips

Smartphones make up an integral part of our lives. With mobile payments and banking becoming increasingly popular, it is important that you apply the same security measures to your mobile phone as you would to your computer. In the wrong hands, your mobile phone could give the wrong person access to your accounts and ultimately your money. Keeping your phone updated and secure is the first step towards real mobile security.

  • Lock your phone when not in use. Password-protect your device so that nobody else can use it or view the information. Also be sure to store your device in a safe location.
  • Call us on 600 575 556, if you have lost your phone and we will disable your mobile banking user ID and password temporarily. In case you have changed your mobile phone number, please let us know and we will update your contact details.
  • Clear mobile frequently by deleting text messages from financial institutions, especially before sharing, discarding or selling your device.
  • Never disclose via text message any personal information (account numbers, passwords, or other personal information) that could be used for ID theft.
  • Always download apps from trusted sources.
  • Keep your phone's Operating System (OS) and apps updated.
  • Do not store passwords or accounts numbers on your mobile phone.
  • Limit the amount of personal details or contact information that you store in your phone, as criminals may be able to retrieve them if you happen to lose your phone.
  • Make a note of your phone's IMEI number (dial *#06# to get it). This makes it easier to disable a stolen phone.
  • For iPhone users, never jail-break or crack the device. Activate encrypted backup in iTunes, and turn on the passcode lock for the phone.
  • For Android users, never root or crack the device.
  • Never use any proxy or VPN software paid/free while accessing your mobile banking and online banking.
SIM swap fraud

Under SIM swap fraud, fraudsters manage to get a new SIM card issued against your registered mobile number through the mobile service provider. With the help of this new SIM card, they get access to One Time Passwords (OTP) and alerts required for making financial transactions through your bank accounts.

How do fraudsters operate?

Step 1 : Fraudsters gather customer's personal information through phishing, vishing, smishing or any other means.

Step 2 : They then approach the mobile operator and get the SIM blocked. After this they visit the mobile operator's retail outlet with the fake ID proof, posing as the customer.

Step 3 : The mobile operator deactivates the genuine SIM card and issues a new one to the fraudster.

Step 4 : Fraudster then generates a One Time Password (OTP) required to facilitate transaction, using the stolen banking information. This OTP is received on the new SIM held by the fraudster.

How to protect yourself from fraud:

  • If your mobile number has stopped working for a longer than usual period, enquire with your mobile operator to make sure you haven't fallen victim to the scam.
  • Register for SMS and any other alert mechanism available to stay informed about the activities in your bank account.
  • Regularly check your bank statements and transaction history for any irregularities.

Preventing card fraud

Credit card security

We monitor your account 24/7 for any suspicious or out of the ordinary activity and will contact you straight away if we notice anything unusual. If your card is lost or stolen or you notice any unusual transactions on your account, make sure you contact us immediately on 600 575 556.

What to look out for

There are various frauds linked to stealing your money and credit card details for unauthorized purchases:

  • Card not present fraud - Fraudsters may access your credit card details from old receipts to purchase high value items on the internet or phone where the retailer does not need to see the card to authorize the purchase, for example: card not present.
  • Cash machine (ATM) fraud - Devices are planted in cash machines by fraudsters in order to skim the card details and use them for unauthorized purchases at a later date. The fraudster may also be watching at the cash machine to steal your card and PIN.
  • Counterfeit fraud - Counterfeit is a term used to describe the manufacture of a credit card so it looks like a genuine card. Genuine credit cards are then “skimmed” and the details duplicated onto the counterfeit card via the magnetic strip.
  • Mail not received fraud - Cards are stolen in the post before the cardholder receives them and used for fraudulent purchases.

Keeping your financial and personal information secure is our highest priority. We use the most sophisticated levels of technology and processes to protect your privacy and security and prevent fraudulent transactions on your credit card.
