3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

Ars Technica's Dan Goodin reports that the UEFI bootkit BlackX, documented by Kaspersky, infected fully patched Windows machines by exploiting the "Baton Drop" Secure Boot bypass (CVE-2022-21894).

Read the original at arstechnica.com. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 27 of 137 with a score of 0.68. The panel rated it highest on reader interest (0.82) and new information (0.73), lowest on audience breadth (0.64). The judges disagreed most on new information (spread 0.60), so the story is marked contested. Placed No. 27, No. 17 by score alone: the seventh Security story of the day (−0.080), and close to “Code-execution flaw in UEFI firmware affects most servers on planet Earth”, No. 6 on Wednesday 28 October 2026 (−0.003). The placement terms move stories; they are not part of the score.

AI judgeJudge 2claude-haiku-5-5
Substantive security reporting on a UEFI bootkit bypassing Secure Boot with technical detail and cited sources; not new relative to recent coverage of BlackLotus/Baton Drop, but practically relevant to IT admins and builders of secure systems.
AI judgeJudge 3gpt-5.6-luna
A well-supported security report explains how BlackX bypasses Secure Boot despite installed patches, exposing a consequential deployment and communication gap in Microsoft’s mitigation process. It offers substantial technical and operational relevance without strongly overstating the evidence.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
