Reporting a cyber security threat

Keeping our information, systems and services secure is a top priority for ASB.

Responsible disclosure programme

We value insights from security researchers that may help us mitigate cyber security risk. Our responsible disclosure programme helps ensure any potential risk is managed promptly, safely and securely.
 
If you believe you have discovered a suspected cyber threat or security issue that affects the confidentiality, integrity or availability of ASB's information, systems or services ("vulnerability"), please submit a report to our security team using one of the methods below.
 
To ensure the protection of our customers, we treat all information regarding a vulnerability as confidential and ask that you do not publicly disclose, discuss or confirm the details of any suspected security issues.

How to report a security issue

Email our Cyber Security Team at vulnerability@asb.co.nz. If you feel the email should be encrypted you can download our PGP key here.

We recommend using this email structure to help us investigate your report:

  1. Affected product or service, including URL(s)
  2. Your name and contact information
  3. If you do not wish to provide your personal information, you may contact us anonymously or use a pseudonym
  4. Date, time and time zone of when the suspected vulnerability was discovered
  5. The IP address used when suspected vulnerability was discovered
  6. What steps to take to reproduce the vulnerability

What happens next?

You'll receive an automated reply when we receive your cyber security disclosure.
 
We will use the information you provide to enhance the security of our systems. We may also use the information in notifications to regulatory bodies, to comply with laws, and assist government or law enforcement agencies. This includes those of our parent company, Commonwealth Bank of Australia.
