What to do:
Behavioural information helps us understand patterns in how you interact with your device such as how you hold your phone, tap on the screen, or type. CommBank uses this information to help detect suspicious cyber activity and financial crime, helping protect you from fraud, scams, and identity theft.
Behavioural information refers to data that measures patterns in how an individual moves, behaves, or interacts with their device. It can include factors such as how a device is held or moved, how a person types or taps on the screen, and other routine interaction patterns. This information reflects behaviour rather than personal content, and is often used to help verify identity or detect unusual activity.
CommBank is collecting behavioural information about the way you interact with your devices while using the CommBank app, NetBank and CommBiz. This includes information about how you interact with your devices such as typing speed, keystroke patterns and mouse movement to help identify potential fraud.
CommBank collects behavioural information to help detect suspicious cyber activity and financial crime to combat fraud and scams, such as identity theft.
Behavioural information allows CommBank to understand how a customer typically uses their device. When activity falls outside these patterns, it may signal a customer’s account has been compromised or unauthorised device use.
The way that you interact with our digital platforms is used to help identify if a third party is in control of your banking. All behavioural information we collect is held by our trusted third party in a de-identified form to help maintain your privacy.
Your behavioural information will only be collected when you are using the CommBank app, NetBank and CommBiz.
If you don’t consent to this information being collected, you won’t be able to use these platforms. We can support you to remove your NetBank ID if required.
If you don’t want CommBank to collect this information for you or your child (who is under 14 years old), you will need to go to a CommBank branch and request the removal of their Netbank ID or de-register devices that have the CommBank App.
There may be a time when we will reach out to you to confirm information on your account or your identity.
Having accurate and up-to-date details is part of our ‘Know Your Customer (KYC) requirements. It also helps us protect you from fraud, as we can contact you immediately if we detect any suspicious activity.
If you’re ever concerned whether the person you’re speaking to is legitimately from CommBank, you can use the CallerCheck feature in the CommBank app to verify your caller’s identity.
Regardless of whether the caller has been identified, we will never ask you to transfer funds, share your screen or reveal your passwords.
Ceba can help you lock your card or securely connect you to a specialist in the CommBank app.
Fast-track your call, see expected wait times and connect with a specialist in the CommBank app.
Send us a copy or screenshot if you receive a hoax email or SMS.
