An AI advantage for software defenders
Does more powerful vulnerability detection help defenders get ahead of attackers? A preprint examines Project Glasswing, which gave selected large US technology firms early access to Claude Mythos Preview. Using publicly disclosed software vulnerabilities, the author finds that participating firms more than doubled their disclosures relative to Chinese and Russian technology firms without access, while continuing to fix reported flaws as quickly as before. External researchers reported fewer vulnerabilities in participating firms’ software and more elsewhere, rather than leaving the market.
The additional disclosures did not come with a detected increase in the number of exploited vulnerabilities. The share exploited within a month of disclosure fell by about two thirds, largely because fewer were already being exploited when disclosed. These findings suggest that AI can strengthen defensive discovery, while also showing how restricted access could distribute security gains unevenly across countries. Public disclosure records, however, cannot establish the full picture of undisclosed flaws and attacks.
Editorial context written by AI from abstracts, not independent scientific validation. The kit and its verified quotes rely on the source paper, not on this letter.
Talk about a paper in public without overstating it: yours, one you are asked to comment on, or one you write about as a journalist.
- Your paper: a draft release for your press office, the questions journalists will ask with what the paper lets you answer, the likely misreadings, a lay summary and a short thread.
- Asked to comment: what the paper shows and does not, its strengths and weaknesses with their passages, and what would settle its main claim.
- Writing about it as a journalist: reporting angles, the wording to check before publication, and the questions to ask the authors.
- For everyone: findings with their passages checked word for word, the novelty set against the closest earlier papers, a hype check, figures with their credit, and researchers for an outside view who have not signed with the authors.
