HSD has a Responsible Disclosure Policy for its IT systems. Talha Saleem is a security researcher who discovered a bug in our website. It concerned the web server containing a robots.txt. The robots.txt in itself is not a vulnerability, however, an attacker could use this to map out the site's conent.
Our website developer Maaike Media quickly took action and solved the issue. We are very grateful for their expertise and professional response.
The HSD Responsible Disclosure Policy is based on the Guideline Responsible Disclosure published by the NCSC and was introduced after the HSD Café on Ethical Hacking and Responsible Disclosure during the Cyber Security Week 2015.
Thank you Talha Saleem for pointing out this vulnerability!
