That\u2019s both because their public codebases are easier for AI systems to explore for vulnerabilities and because many such projects rely on wildly insufficient volunteer maintenance for their security.<\/p>\n<p>In <a href=\"https:\/\/www.nytimes.com\/2026\/04\/15\/opinion\/mythos-open-souce-internet.html\" rel=\"nofollow noopener\" target=\"_blank\">a New York Times essay last week<\/a>, Mozilla CTO Raffi Krikorian argued that the human difficulty of both finding bugs and writing complex software has created a kind of balance in cyberthreat research that Mythos could break wide open. \u201cThe programmer who gave 20 years of his life to maintain [open source] code that runs inside products used by billions of people? He doesn\u2019t have access to Mythos yet.
