You will be hearing ohhh so much about Anthropic, Claude, Mythos, and Glasswing if you haven’t already. If you don’t know what all these are now, you will need to. Regardless of how well- or poorly-versed you think you are, start here.

And be sure to check out my related book review of Nicole Perlroth’s must-read, award-winning book on cyberwarfare as well as my own work on cyberwarfare. And finally, apologies for the delay, so here’s a real meaty edition on a meaty topic!
Let’s jump into it! Mythos, a particular iteration of the artificial intelligence juggernaut Anthropic’s Claude large language model (LLM) chatbot, is here and doing its thing in the form of Anthropic’s Project Glasswing.
Yes, these tech people are way too in love with their naming schemes, but the bottom line is that Anthropic just announced it has been using its new LLM bot Mythos (still in development and often more specifically referred to as Mythos Preview) in a massive project with some of the biggest names in tech overall: Amazon Web Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto Networks that has been something of a secret, but is now unveiled as Project Glasswing.
First, let’s start with a few primers on what, exactly, the Mythos (Mythos Preview) edition of Anthropic’s Claude LLM model actually it:
- Anthropic’s Mythos Will Force a Cybersecurity Reckoning—Just Not the One You Think—Lily Hay Newman; Wired.
- What is Claude Mythos and what risks does it pose?—Liv McMahon Joe Tidy; BBC News.
- It’s the End of the Internet as We Know It—Raffi Krikorian (Mozilla CTO); The New York Times.
- What is Mythos, Anthropic’s unreleased AI model, and how worried should we be?—Chris Stokel-Walker (edited by Eric Sullivan); Scientific American.
- What is Mythos AI and why could it be a threat to global cybersecurity?—Dan Milmo, Kalyeena Makortoff, and Aisha Down; The Guardian.
Anthropic seems to have won a key portion of the AI development race that more and more resembles an arms race, the space race, and the Manhattan Project race (take your dangerous pick of a comparison). It won by developing the Mythos version of its popular Clause LLM model, and Mythos has an advantage over its competition at the time in that it can, and is, finding hacking security vulnerabilities no other model, let alone a human, has been able to yet find. And, according to new information released by Anthropic, it is finding thousands of the dangerous vulnerabilities. In the wrong hands, this can be incredibly destructive, so much so that it is shrouded in secrecy and deemed too dangerous for a general public release by Anthropic. Yes, like Big Tech Santa, Anthropic is keeping its list and constantly automatedly checking it, determining whom it thinks has the ethical and moral substance to be granted access.
- Here is the detailed introduction to Glasswing and its first major update on results: Project Glasswing: Securing critical software for the AI era and Project Glasswing: An initial update—Anthropic.
- Anthropic sure as hell said a hard no to Secretary of Defense (not legally “War,” sorry fratbros) Pete Hegseth and his Pentagon, which had refused to limit the use of Anthropic’s AI for “mass government surveillance” and “fully-automated weapons,” to quote a detailed explanation from Dario Amodei, Anthropic’s CEO, which I cited in my very first of these AI Reading Lists. That fight is still ongoing legal and is shaping much of the below discussion… Appeals court judges appear to be divided over Pentagon’s legal dispute with AI company Anthropic—Michael Kunzelman, The Associated Press/Federal News Network.
- Mozilla’s CTO has a stark warning: It’s the End of the Internet as We Know It—Raffi Krikorian; The New York Times.
- BBC isn’t afraid to be afraid with the excellent Scott Galloway: ‘Is Anthropic the new Dr Frankenstein?’—BBC News/AI Decoded.
- Tom Friedman sees major warning signs in the Pentagon-Anthropic fight: Anthropic’s Restraint Is a Terrifying Warning Sign—Thomas L. Friedman, The New York Times.
- Speaks for itself: The risks of Mythos are no myth, The Editorial Board, Financial Times.
- Yes, this is a big deal… Six Reasons Claude Mythos Is an Inflection Point for AI—and Global Security—Gordon M. Goldstein, Council on Foreign Relations.
- So much is poised to change as far as cybersecurity: The Detection Era Is Over: How Mythos Changes Everything—Jesse Green; Rubrik.
- Umm, don’t forget the workers and watchdogs?? Anthropic Warned Big Companies About Mythos. Workers and Watchdogs Need a Seat at the Table—Amber Scorah, Rebecca Petras; Tech Policy Press.
- Not long after telling the Pentagon no, Anthropic also told Xi Jinping and the Chinese Communist Party to take a hike on seeking access to Mythos: China Sought Access to Anthropic’s Newest A.I. The Answer Was No.—Dustin Volz, Julian E. Barnes, Sheera Frenkel, and Tripp Mickle; The New York Times.) Two bad actors, two NOs from Anthropic. Good for Anthropic!
- The absurd Pete Hegseth and his flailing Pentagon sure hate Anthropic for clinging to ethics and morals, but still want to use Mythos: Pentagon Reportedly Plans to Adopt and Weaponize Latest Cyber-Capable AI Models—Mike Pearl; Gizmodo.
- Despite being out with the Pentagon, Anthropic is apparently has been cool with the National Security Administration (NSA) spying agency and will continue to be cool: White House Approves $9 Billion for Spy Agencies to Catch Up on A.I.—Dustin Volz and Julian E. Barnes; The New York Times.
- Japan’s government and its premier financial institutions are supposedly set to receive access to Mythos, although this is the U.S. government in 2026 so if something completely contradictory happens, don’t be surprised: Japan gov’t to get access to Anthropic’s latest AI: finance minister—Kyodo/Japan Today. This is all in the context of the Japanese government very much taking cybersecurity seriously and proactively in the wake of Mythos’ announcement: Japan scrambles to boost defenses against threats from Mythos—The Asahi Shimbun.
- The arrival of mythos has complicated the Trump Administration’s AI “plans” (think more vibes, but dangerous and reckless): How Anthropic’s Mythos Threw the White House AI Strategy Into Chaos—Amrith Ramkumar Follow , Brian Schwartz Follow and Natalie Andrews; The Wall Street Journal, even as, somehow, the Trump Administration is involved in its rollout and not in a transparent way: White House Opposes Anthropic’s Plan to Expand Access to Mythos Model—Robert McMillan and Amrith Ramkumar; The Wall Street Journal
- This is all in the context of Trump just days ago backing down from an executive order for a major safety review of AI, at the behest of Big Tech: How big tech got its way on Trump’s AI executive order—Nick Robins-Early, The Guardian and Trump calls off AI executive order over concern it could weaken US tech edge—Collin Binkley and Matt O’Brien, The Associated Press.
- BONUS: A co-founder of Anthropic, Chritopher Olah, is about to launch an encyclical on AI—“Magnifica Humanitas”—tomorrow with Pope Leo. A primal scream for ethics in an unethical field, if ever there was one… What we know about Pope Leo’s upcoming A.I. encyclical—Colleen Dulle and Gerard O’Connell; America: The Jesuit Review/Inside the Vatican.
