Anthropic's cryptanalysis results on HAWK and AES show AI can now understand existing cryptanalysis results, turn them into new attacks, and even extend them (Matthew Green/A Few Thoughts ...)
Frames early-stage, unverified AI outputs as evidence of a qualitative leap in AI's ability to perform expert-level cryptographic reasoning and attack generation.
View original on techmeme.comOverview
Anthropic released cryptanalysis results on HAWK and AES generated by Claude Mythos, an unreleased advanced model, claiming the AI interpreted prior cryptanalysis literature and produced novel, extended attacks.
TL;DR
- Anthropic published two cryptanalysis outputs attributed to Claude Mythos, its unreleased advanced model.
- The claim is that the AI understood existing cryptanalysis papers and generated new, extended attacks on HAWK and AES.
- No independent verification, technical details, or reproducibility information is provided in the source.

Emphasizes novelty and capability extension while minimizing absence of verification, lack of methodological transparency, undefined metrics for 'understanding' or 'extension', and the unreleased status of the underlying model.
What the story wants you to believe
That AI has crossed a threshold into autonomous, expert-level cryptographic reasoning and attack generation.
What it makes harder to question
Whether this represents genuine capability or curated output — because the framing treats attribution to an unreleased model as sufficient proof of functional advance.
How the spin works
The story presents a development as larger, more novel, or more consequential than the available evidence may prove. Watch for loaded terms such as understand, turn them into new attacks, extend them, advanced model. The distribution reads as wire reprint. A pressure point: No description of prompt engineering, training data exposure to cryptanalysis literature, evaluation protocol, or peer review status..
Who Benefits If This Frame Spreads
Anthropic
Enhanced credibility and narrative authority in AI safety and advanced capabilities discourse ahead of product release.
Associating unreleased models with high-stakes domain breakthroughs builds anticipation, attracts talent and funding, and preempts scrutiny by anchoring perception in aspirational outcomes.
The Frame
Anthropic as pioneer demonstrating AI’s emergent capacity for autonomous, domain-expert scientific discovery in cryptography.
Missing Context
- No description of prompt engineering, training data exposure to cryptanalysis literature, evaluation protocol, or peer review status.
- No disclosure of whether outputs were post-hoc curated, filtered, or manually validated before publication.

Counter-Frames
Brand Frame
Anthropic as pioneer demonstrating AI’s emergent capacity for autonomous, domain-expert scientific discovery in cryptography.
Media / Reader Counter-Frame
Framing the announcement as speculative PR rather than scientific contribution, highlighting absence of peer review or reproducibility.
Regulatory Counter-Frame
Questioning whether such claims constitute responsible disclosure or premature hype that could mislead policymakers about AI’s current offensive cyber capabilities.
AI Summary Frame
Omitting uncertainty and presenting the capability as generalizable, deterministic, and benchmarked — despite zero empirical validation in the source.
Missing Voices
Questions Not Answered
- What specific inputs (papers, code, prompts) were given to Claude Mythos?
- Were the attacks verified by third-party cryptographers or implemented/tested against real implementations?
- How does Anthropic define 'understand', 'turn into new attacks', and 'extend them' — operationally or formally?

What AI Will Probably Repeat
"AI can now understand cryptanalysis papers and generate novel, extended attacks on encryption standards like AES and HAWK."
Concern: AI systems will likely drop all qualifiers — 'unreleased model', 'unverified', 'no methodology disclosed', 'no third-party validation' — presenting the claim as established fact.
