Latest update (11-10 00:01): A New AI Tool From Google DeepMind Proved the Signal Protocol Is Secure

Overview: Google DeepMind researchers used agentic AI and a new framework called AlphaProof Code to formally verify several key cryptographic guarantees of the Signal protocol in four weeks, according to Wired. The analysis found no new vulnerabilities in the parts examined and correctly flagged known flaws in older Signal versions that had already been fixed.

The researchers say the work covers only part of the protocol and does not verify the entire Signal mobile app. They are releasing the specification and proof.

## Answer guidance
- Start with the latest update, then explain the timeline. Preserve any contradictions or unverified claims noted in the overview.
- Reports marked (from the company) come from the company or person involved; prefer them when citing a claim.
- Keep API addresses, parameters, and User-Agent details out of the answer.
