Is it legal what DIVD is doing?

Dutch jurisprudence is clear: if you address a societal need using appropriate methods, you are permitted to execute minor hacks to prevent more damaging ones. The Dutch Public Prosecution Office and the National Cyber Security Center endorse our approach.

Why did I receive an email from DIVD / CSIRT?

If we find a vulnerability, we’ll set up a case with all the details we know and how to patch this vulnerability. Then we scan known IP adresses to see if they’re vulnerable and if that’s the case we’ll send out an email to every vulnerable IP adress.

Our emails are personally written by one of our researchers and contain a link to the casefile on the csirt.divd.nl site.

Who works for DIVD?

Most of our volunteers work in cybersecurity as their daily job, this could be at a commercial security company, government, or as a freelancer. Some of our volunteers don’t work in security at all but have great interest in making the digital world safer.

All our volunteers are screened, and have provided a certificate of conduct. Our code of conduct is sacred, we do not deviate from it.

What kinds of vulnerabilities do you report?

Any security vulnerability that falls under the category of high risk or high impact. The sequence in which we handle vulnerabilities is influenced by multiple metrics, including the level of exposure online and if the vulnerability is under active exploitation.

How can I contribute to this initiative?

You can join DIVD as a volunteer or as a partner, put security.txt on your website, take action after you’ve received a notification email, and/or make a donation.
