System Vulnerability Disclosure Policy

This Policy sets out the terms and conditions of our Responsible Disclosure Programme. If you have discovered any vulnerabilities in our systems, please report these to us as soon as possible.

How to report vulnerabilities to hummgroup

Report system vulnerabilities to us as soon as possible so that we can improve the safety and reliability of our systems promptly. To report any such system vulnerability, use the Submission Form at the end of this Policy. Once we have received your report, a team of security experts will investigate your findings. We endeavour to provide an initial response to any system vulnerability report within three working days (please note that there may be a delay in responding due to workload or holidays). Please be aware that this Policy is not intended to, and does not cover matters relating to complaints, fraud, and other similar matters. Please see the section headed “Excluded from reporting,” below.

Rewards

hummgroup will pay a reward for qualifying system vulnerabilities reported in accordance with this Policy, if the reported vulnerabilities have been remediated. The amount of the reward is subject to an assessment of the severity of the system vulnerability reported, the type of website (static information sites versus transactional sites) concerned and the quality of the report we receive. If the report is of great value for the continuity and reliability of the company or our services, the reward will be considerably higher. Please note: going public with your finding will exclude you from eligibility for the reward. Please report the system vulnerability in accordance with this Policy and talk to our security experts so that we may assess and solve the problem. No reward will be provided if we find evidence of abuse or violation of the terms of this Policy.

System Vulnerability Disclosure Requirements

The following system vulnerability disclosure requirements apply in order for a report to qualify for a reward under this Policy:

do not cause any damage to our systems;
do not utilise social engineering in order to gain access to our IT systems;
never let your investigation disrupt our online and other services;
do not store, share, compromise or destroy hummgroup or customer data. If personal data is encountered, you should immediately halt your activity, purge related data from your system, and immediately contact hummgroup;
do not put a backdoor in the system, not even for the purpose of showing the system vulnerability. Inserting a backdoor will cause even more damage to the safety of our systems;
do not make any changes to or delete data from the system. If your finding requires you to copy the data from the system, do not copy more data than necessary. If one record is sufficient, do not copy any more records;
do not attempt to penetrate the system any further than required for the purpose of your investigation. Should you have successfully penetrated the system, do not share this gained access with others;
do not utilise any brute-force techniques (e.g. repeatedly entering passwords) in order to gain access to the system; and
do not use techniques that can affect the availability of our online and other services.

Please be aware that:

system vulnerabilities detected and reported by hummgroup employees or former employees are not eligible for any reward;
if your reported system vulnerability has also been reported by another person, any associated reward will be granted only to the first person to report the system vulnerability in question;
multiple reports for the same system vulnerability type with minor differences will be treated as one report (ie. only eligible for a single reward); and
if you are eligible for a reward, you must provide your personal information and any other information we reasonably request in connection with your report, in order to provide you with the reward.

Your privacy

We will only use your personal information to get in contact with you and to undertake actions with regard to your reported system vulnerability. We will otherwise handle your personal information in accordance with our Privacy Policy.
