Responsible disclosure: DIVD describes a “long and windy road” notifying a Chinese firm

Some of  you will recall that on a few occasions, DataBreaches has collaborated with Dutch researcher Jelle Ursem (aka @SchizoDuckie) to report on entities in the medical sector who were leaking their login credentials in GitHub repositories (see “No Need to Hack When It’s Leaking” and “Good Luck Explaining to HHS Why Your PHI is in GitHub’s Vault for the Next 1,000 Years.”

But Jelle’s findings and responsible disclosures are not just confined to the medical sector. Far from it. Jelle went on to join forces with the Dutch Institute for Vulnerability Disclosure (DIVD). This week, one of his colleagues presented one of his more interesting — and concerning — discoveries.  But what makes this presentation even more unusual and dare I say it — entertaining — is that just before the presentation started, the vendor got in touch with DIVD and asked them to cancel their presentation.

Watch what happens next.  First, though, their background for the presentation:

IOT: International Outage Technology (Disclosure of DIVD-2022-00009)

DIVD researcher Jelle (aka SchizoDuckie) has a hobby. He likes to find credentials in places where they don’t belong, like GitHub and Postman. And this hobby has gotten him into many places he should not have, like the Dutch Tax office and many larger company.

But, in February 2022 he found an account with an even bigger reach, an account who’s abuse could mean trouble for our national critical infrastructure. His simple GitHub query uncovered a secret that could switch off a country, now what…

While Jelle is enjoying his vacation his DIVD colleagues, Chris van ‘t Hof, Célistine Oosting and Frank Breedijk, will present the story of one of the more significant vulnerabilities discovered by DIVD this year. The long windy but mostly slow and silent road to disclosure and remediation and how mitigation did not take away all the risks.

This talk digs into the, up to this point, untold story of case DIVD-2022-00009 and will include numbers “Doc” Brown will jealous of.
