Description

Responsible Disclosure indicates ING’s continued commitment to improve its security posture. As part of this process, we work closely with security researchers to identify and report vulnerabilities they find within our systems. ING appreciates security researchers efforts in reporting vulnerabilities on its systems as long as the discovered vulnerability is in scope, detected without the use of intrusive testing techniques, and follows the disclosure guidelines below:

Bounties

This is a responsible disclosure program without bounties.

Rules of engagement
Not applicable
Not applicable
max. 10 requests/sec

Reports are required to be written in English. Please include a clear attack scenario outlining detailed reproduction steps.
Make sure that during your investigation you do not cause any damage or disruptions to our systems so do not alter, change or delete data from our systems. Do not put a backdoor in the system, not even for the purpose of showing the vulnerability as inserting a backdoor will cause even more damage to the safety of our systems and do not penetrate the system any further than required for the purpose of your investigation.
Make sure that during your research you do not inadvertently cause a data breach (i.e. sharing screenshots or recordings on 3rd party cloud solution).

Law regulations for Responsible Disclosure may differ by country. We strongly advise you to take these regulations into account. Your investigation on our systems could be regarded as a criminal act under local or international law and you may then risk criminal prosecution. If you have detected vulnerabilities in one of ING’s systems, please be aware that local law takes precedence over ING rules. Nevertheless, if you act in good faith and according to ING’s rules, we will not report your actions to the authorities, unless required to do so by law.

Introduction

At ING, the safety of internet banking and the continuity of our online services are our top priorities. Our specialists work continuously to optimise our systems and processes. Despite the effort we put into the security of our systems, vulnerabilities can still be present.

Do you have the skills and have you discovered any vulnerabilities in our systems? Please help by reporting them to us, so that we can improve the safety and reliability of our systems together.

To encourage reporting vulnerabilities to ING, we would urge you to send any vulnerability you detect to us. Any researcher who provides a high quality report which will be important for the continuity and reliability of the bank will be invited to the private ING program in Intigriti. A financial reward is also possible after the invitation.

We are happy to announce our program! We've done our best to clean up our known issues and now would like to request your help to spot the ones we missed!
