The cybersecurity firm Sysdig documented what it describes as the first ransomware operated entirely by an autonomous artificial intelligence agent. Dubbed “JadePuffer”, the program exploited a known vulnerability in Langflow, a platform for building AI applications, moved through the network, escalated privileges and encrypted more than 1,300 configurations with no human intervention, adapting in real time to the failures it encountered along the way.
The finding matters above all because of its timing: it comes just one week after the United States lifted the block on Claude Mythos 5, the model Anthropic designed precisely to defend against this kind of attack through its Project Glasswing program. With a real, autonomous offensive now recorded outside any lab, the idea of an AI that attacks on its own is no longer a hypothesis. For Latin America the news weighs double: the region never had access to Glasswing or its defensive tools, and now its banks, energy companies and telecoms face public evidence of offensive capabilities that already operate on their own. The asymmetry is clear: the capacity to attack spreads faster (and more cheaply) than the capacity to defend.

- Microsoft replaces OpenAI and Anthropic with its own MAI models in Excel and Outlook — It is the first major corporate customer to scale back its use of paid frontier models, driven by costs.
- No AI lab scores above a “C+” on the Future of Life Institute’s new safety index — Anthropic tops the list, but with a mediocre grade; the three front-runners weakened safety commitments they had already made.
- Chinese open models such as GLM-5.2 gain ground in US companies by being up to five times cheaper — The price pressure also opens up infrastructure options for Latin American developers on a limited budget.
In the region
The week closed with the first UN Global Dialogue on AI governance in Geneva moving from the opening to concrete commitments: Chile presented four proposals (regulatory sandboxes, ISO certifications, open data and continuing education) and the region confirmed a next meeting in New York for May 2027. In parallel, UNESCO and CAF set up the Regional Group of Specialists on Disinformation and AI, a follow-up mechanism (with a rapid-response manual for disinformation) to the Santo Domingo Roadmap signed in late June.
On the legislative front, Chile reopened for the third time the dispute over AI and copyright within its sweeping reform bill: the attempt to exempt AI platforms from paying for protected content is back on the table after two previous rejections, with a deadline for amendments that expires on July 9. A side note is worthwhile: the OECD Employment Outlook 2026, which was expected to include a chapter devoted to AI, ended up treating it as just one more of the “technological shocks” in a report focused on geographic disparities in employment.
Launches
- GitHub Copilot, desktop app — Agent-assisted development on macOS, Windows and Linux is now available even on the free plan, with support for using your own model key without a subscription.
- J-Lens, interactive demo on Neuronpedia — An open-source tool from Anthropic for exploring a model’s internal “workspace”; good teaching material for interpretability courses.
- Gemini API — Managed Agents — It lets you run tasks in the background and connect to remote servers, now also on the free tier.
Threads we’re following
This offensive comes in the middle of a story we have been following: for about two and a half weeks in June, US export controls cut off access to the Fable 5 and Mythos 5 models for users outside the country (all of Latin America included), until access was restored globally on July 1. This week the startup Legion LegalTech dropped its lawsuit against the Department of Commerce, filed precisely over that blockade. The episode closes in court, but the underlying question remains: when and under what rules the region gets access to the tools, offensive and defensive, that are being defined far from its borders.
If fully autonomous ransomware is already real and the region never had access to the defenses designed to contain it, is Latin America more exposed to the risks of AI than to its benefits?
Correction (September 30, 2026). The original version said the Santo Domingo Roadmap was signed a year ago; the correct date is June 25 and 26, 2026, when it was adopted at the ministerial summit in Santo Domingo, according to OECD.AI and UNESCO.
