"This report outlines several case studies on how actors have misused our models, as well as the steps we have taken to detect and counter such misuse. By sharing these insights, we hope to protect the safety of our users, prevent abuse or misuse of our services, enforce our Usage Policy and other terms, and share our learnings for the benefit of the wider online ecosystem. The case studies presented in this report, while specific, are representative of broader patterns we're observing across our monitoring systems. These examples were selected because they clearly illustrate emerging trends in how malicious actors are adapting to and leveraging frontier AI models. We hope to contribute to a broader understanding of the evolving threat landscape and help the wider AI ecosystem develop more robust safeguards.

The most novel case of misuse detected was a professional 'influence-as-a-service' operation showcasing a distinct evolution in how certain actors are leveraging LLMs for influence operation campaigns. What is especially novel is that this operation used Claude not just for content generation, but also to decide when social media bot accounts would comment, like, or re-share posts from authentic social media users. As described in the full report, Claude was used as an orchestrator deciding what actions social media bot accounts should take based on politically motivated personas. Read the full report here."

There's a lot that could still be improved in #swad, but I don't get that "proof of work" idea out of my mind, so I started a branch to work on it:

github.com/Zirias/swad/pull/1

I really think it makes sense when you want some publicly known "guest login" which is still protected against #bots. Not sure yet whether this will succeed, we will see!

It certainly won't be as "fancy" as #anubis, but do the same thing functionally: Require the client to find a #nonce that, combined with a server-provided #challenge, hashes to something with 'n' leading zeros using #sha256. In contrast to anubis, swad won't have to proxy everything (but rely on nginx' auth_request), and no challenge will be issued when the user logs in with credentials some *other* credentials checker accepts.

Add a credentials checker that accepts the result of some "proof of work" (of the same kind used in "anubis") instead of a password. This should allow well-known "guest log...
