GitHub Ban Escalates Microsoft’s YellowKey Dispute


TL;DR

  • GitHub Account: Nightmare-Eclipse appears to have lost its GitHub account after Windows exploit code hit the platform.
  • YellowKey Risk: Microsoft now tracks the BitLocker bypass under CVE-2026-45585, keeping the dispute tied to a live Windows security issue.
  • July 14 Threat: Chaotic Eclipse tied July 14 to a possible retaliatory move or release, while the fight over disclosure and bounty handling remains unresolved.

Security researcher Nightmare-Eclipse appears to have lost his GitHub account after Windows zero-day exploit code hit the platform. An earlier GitHub-hosted exploit clash had already turned the same fight public.

Earlier in May 2026, security researcher Chaotic Eclipse brought the YellowKey zero-day into public view, with the BitLocker bypass described as opening protected Windows 11 drives with a simple USB key. Microsoft is also accused of deleting Chaotic Eclipse’s Microsoft account used for bug reporting. Nightmare-Eclipse said the work brought “got zero pennies from doing so.”

The dispute also includes accusations that Microsoft ignored zero-day reports and withheld bounty payments, although supporting evidence has not yet been released. Microsoft has not publicly explained the GitHub-ban allegation itself, but on May 27 the company cast YellowKey and related exploit releases as violations of its coordinated vulnerability disclosure process.

Microsoft’s Disclosure Rules Collide With the YellowKey Dispute

Microsoft’s public researcher portal still accepts submissions from anyone, regardless of past interactions or reputation. The policy now sits in direct tension with a researcher tied to the same dispute losing account access during the fight.

CVD, or coordinated vulnerability disclosure, is the private handoff vendors want before flaw details become public. MSRC is Microsoft’s security response team for those reports and for the bounty decisions that can follow. Researchers weighing that channel now have to judge whether a process that stays open on paper will still protect a combative submitter during a live dispute.
