Provenance Record

Well-structured News piece covering a high-signal cybersecurity story. The article follows a clear What We Know / What We Don't Know / Analysis format with appropriate technical depth for the target audience. Word count (839) is within the News range (400-1200). Technical claims about cldflt.sys, the HsmOsBlockPlaceholderAccess routine, OBJ_FORCE_ACCESS_CHECK, and the race-condition mechanism are accurate per sources. The Analysis section provides useful threat-model context without editorializing.

Read source-0.html.gz (BleepingComputer), source-1.html.gz (The Hacker News), source-2.html.gz (CyberSecurityNews via Archive.org), source-3.html.gz (NotebookCheck), source-4.html.gz (zero-day-wire-1.ghost.io). All five snapshots fetched successfully (source-2 via Archive.org fallback). Key findings: (1) BleepingComputer (source-0) confirms the exploit was tested and opened a SYSTEM command prompt, confirms CVE-2020-17103 / James Forshaw / September 2020 / December 2020 fix, confirms BlueHammer/RedSun/UnDefend/YellowKey/GreenPlasma disclosure sequence and the 'mopped the floor' protest quote. (2) The Hacker News (source-1) confirms CVE-2025-62221 CVSS 7.8 patched December 2025, confirms James Forshaw/Project Zero, and provides Dormann's actual Mastodon wording ('reliably' opening a 'cmd.exe' prompt). (3) CyberSecurityNews (source-2) confirms OBJ_FORCE_ACCESS_CHECK missing flag, confirms 390+ stars, confirms race condition / RtlOpenCurrentUser mechanism. (4) NotebookCheck (source-3) confirms Microsoft has not commented and quotes Microsoft's 'coordinated vulnerability disclosure' standard position. (5) zero-day-wire (source-4) uses third-person reported speech for Dormann's confirmation — the article places this in direct quotation marks, constituting a paraphrase-as-quote issue (see Findings). Three sources not on allowlist (cybersecuritynews.com, notebookcheck.net, zero-day-wire-1.ghost.io) are legitimate security/tech outlets whose content corroborates claims made by primary sources (BleepingComputer, THN).

All technical specifics verified: CVE-2020-17103, James Forshaw, September 2020 report, December 2020 fix, cldflt.sys, HsmOsBlockPlaceholderAccess, OBJ_FORCE_ACCESS_CHECK (confirmed source-2), CfAbortHydration undocumented API (confirmed source-0), RtlOpenCurrentUser race condition (confirmed source-2), ThreatLocker registry key IoCs (confirmed source-0), 390+ GitHub stars (confirmed source-2), BlueHammer CVE-2026-33825 / April Patch Tuesday (confirmed source-0), YellowKey BitLocker bypass / Windows 11 + Server 2022/2025 (confirmed source-0), 'sixth disclosure in six weeks' is accurate per count: BlueHammer(1), RedSun(2), UnDefend(3), YellowKey(4), GreenPlasma(5), MiniPlasma(6). CVE-2025-62221 CVSS 7.8 December 2025 confirmed by source-1. The 'protest' quote ('mopped the floor with me and pulled every childish game they could') is verbatim in source-0. One issue: the article presents Will Dormann's confirmation in direct quotation marks but the cited source (source-4) uses indirect/reported speech — this is a paraphrase-as-quote.

High-quality, well-sourced cybersecurity news piece. All technical claims verified across five source snapshots. One recoverable issue: the Will Dormann confirmation is presented as a direct quote but is a paraphrase of third-person reporting. The substance is fully supported by sources (Dormann did confirm the finding, and the characterization is accurate). APPROVE_WITH_CORRECTIONS with a single corrections record documenting the paraphrase-as-quote.
