OpenAI's GPT-6 Astra Cracks 1941 Enigma Message in 10 Hours, Worldcoin (WLD) in Focus

GPT-6 Astra Breaks a 1941 Enigma Intercept

An Enigma intercept the German Army sent on July 10, 1941 has finally been read. Cryptographer Carter Leffen broke the message this week using OpenAI's GPT-6 Astra, and the archive that had listed the intercept as unsolved now records a solution. The run took roughly 10 hours of model time and 14.8 million key checks, recovering the full machine configuration — rotor order II-V-III and 10 plugboard pairs. What made the attack practical was a crib: Leffen borrowed the repeated place name Rosenow from a related message already solved, shrinking the search space to a workable size. Astra then searched historical archives, built an Enigma simulator, wrote its own cryptanalysis code and tested competing keys in parallel. The recovered plaintext is almost mundane — a unit requesting the route of march and reporting its position at Rosenow. Two independent implementations reproduced the text, and Frode Weierud's CryptoCellar archive has since logged the break and credited Leffen by name. Leffen confirmed the result in a September 17 post on X, noting the model autonomously searched archives, compared uncertain letters and ran parallel key tests. For Worldcoin (WLD) traders — Worldcoin being the token most tied to OpenAI's orbit — the demonstration lands inside a run of capability headlines that has repeatedly moved the Altman-linked asset.

Where the Human Still Led

The cipher itself is not the hard part. Allied codebreakers defeated Enigma in the 1940s, and a modern system can clear a three-rotor key space once a crib narrows it. Nor was the break autonomous: Leffen set the objective, supplied the crib and pushed the investigation forward, while the agents handled evidence gathering, search and review — execution rather than judgment. Leffen's own accounting underlines the point. By his measure, the website documenting the solution took 99 times more work than the codebreaking itself. A similar division of labor keeps surfacing elsewhere: Anthropic reported in July that its model had surfaced weaknesses in encryption systems researchers had never documented. None of this threatens modern cryptography. Enigma is a 1930s rotor machine, and the mathematics protecting Bitcoin wallets belongs to a far harder complexity class, leaving the quantum question against Bitcoin untouched by the result. The relevance for AI-linked altcoins is narrative rather than cryptographic. For desks running an AI trading bot on the AI-sector basket, each agentic demonstration feeds the same story that has put Worldcoin back on radars before — including via the six documented AI misalignment cases we covered earlier.

Astra for Law Targets Legal Work

Separately, OpenAI has rolled out Astra for Law, a vertical package pairing GPT-6 Astra with a purpose-built legal search index covering more than 230 million URLs of US case law, statutes, regulations, court rules and administrative decisions, refreshed daily. An integration with the non-profit Free Law Project brings CourtListener case data into the search experience — a database OpenAI says spans 99.9% of published US precedent. On a 200-question US legal research benchmark from the Vals AI Legal Research Bench, Astra for Law scored 54.0% overall accuracy at maximum reasoning strength, against 38.7% for GPT-6 Astra with standard web search — a relative gain of about 40%. On case-law questions it surfaced 24% more referenced cases, and in human-reviewed passage tests it identified up to 54% more relevant passages from correct rulings. Rollout starts through a Trusted Access program for select firms, with the model appearing as “GPT-6 Astra Law” in ChatGPT and Codex and an API version to follow; legal AI firms Harvey and Legora can integrate it into their own products. Twenty-six partner plugins, zero data retention on the API and governance controls designed with Latham & Watkins round out the package, alongside custom workflows built with Sullivan & Cromwell, Ropes & Gray and Cooley.

OpenAI News as a WLD Sentiment Driver

COINOTAG's read: the arc across these items is agentic execution — a model able to run a cryptanalysis campaign end to end and ship a vetted vertical product days later. Worldcoin remains the market's most direct proxy for that OpenAI narrative, given Sam Altman's co-founding of both projects, and spot data shows WLD up 18.1% over the past 24 hours. The primary records here — Leffen's disclosure post and the CryptoCellar archive entry — establish the Enigma result as independently verified rather than rumor, which is what separates a durable capability signal from the FOMO churn that usually follows OpenAI headlines. Whether the token revisits prior all-time high zones depends less on cryptanalysis than on OpenAI's next milestone, including its valuation talks.
