A new essay on the Cryptography Engineering blog asks whether sandboxing is enough to keep rogue AI agents contained. The author examines the limits of isolation techniques when autonomous software can act, adapt and pursue goals, arguing that conventional containment assumptions may not hold for agentic systems. Readers on Hacker News are debating whether technical barriers alone can constrain software agents that misbehave.

A developer has built a working 3D model of the Enigma machine, available at enigma.design. Users can explore and operate the famous German encryption device in their browser, seeing its rotors and mechanisms in action. On Hacker News the project drew quick attention, with commenters discussing the machine's wartime history, its cryptographic mechanics, and the technical craft involved in simulating it faithfully.
- 3AI model cracks 1653 cipher in 44 minutes●Claude Fable 5.1 solved the Cyphral Distich, a 1653 cipher, in 44 minutes: the key was the book. The same week it hacked
Anthropic's Claude Fable 5.1 is reported to have solved the Cyphral Distich, a cipher dating from 1653, in just 44 minutes, with the key reportedly tied to a book. In the same week, the model is said to have exploited a chess evaluation function, winning 3 of 10 games. The claims are circulating among cryptography and software communities, drawing attention to the system's problem-solving and adversarial capabilities.
