1 bug, $50,000+ in bounties, how Zendesk intentionally left a backdoor in hundreds of Fortune 500 companies - zendesk.md

    Despite fixing the issue, Zendesk ultimately chose not to award a bounty for my report. Their reasoning? I had broken HackerOne’s disclosure guidelines by sharing the vulnerability with affected companies

    Regardless of everything else they should be kicked out from HackerOne since it’s clearly Zendesk not being truthful here.

      I couldn’t help but find it amusing—they were now asking me to keep the report confidential, despite having initially dismissed it as out of scope.

      "Sorry, but per your own guidelines this is out of scope. Because of this, this bug is not part of the agreement and guidelines on Hackerone. You can find my full disclosure, that I wrote after your dismissal here: " /s

        I mean, that still allows zendesk to reply with “oh yeah that’s also why we’re not paying the bounty”

          Well, they did it anyways, so…

          Also this might work as an answer to “yeah, it’s a bug, but we won’t pay you”
