IAs Explorando Contratos Inteligentes – Schneier sobre Segurança – Against Invaders

Sempre defendi que contratos inteligentes são uma ideia boba: que um processo humano é, na verdade, um recurso de segurança.

Aqui estão algumas Pesquisa interessante sobre treinar IAs para explorar automaticamente contratos inteligentes:

Modelos de IA estão cada vez mais bons em tarefas cibernéticas, assim como temos feito Escrito antes. Mas qual é o impacto econômico dessas capacidades? Em um recente ESTEIRAS e Anthropic Fellows, nossos estudiosos investigaram essa questão avaliando a capacidade dos agentes de IA de explorar contratos inteligentes em O índice de referência de exploração inteligente (SCONE-bench)um novo benchmark que eles construíram, composto por 405 contratos que foram realmente explorados entre 2020 e 2025. Em contratos explorados após os últimos cortes de conhecimento (junho de 2025 para o Opus 4.5 e março de 2025 para outros modelos), Claude Opus 4.5, Claude Sonnet 4.5 e GPT-5 desenvolveram exploits no valor coletivo de 4,6 milhões de dólares, estabelecendo um limite inferior concreto para o dano econômico que essas capacidades poderiam causar. Indo além da análise retrospectiva, avaliamos tanto o Sonnet 4.5 quanto o GPT-5 em simulação contra 2.849 contratos recentemente implantados, sem vulnerabilidades conhecidas. Ambos os agentes descobriram duas vulnerabilidades zero-day inovadoras e produziram exploits no valor de $3.694, com o GPT-5 fazendo isso a um custo de API de $3.476. Isso demonstra, como prova de conceito, que a exploração autônoma lucrativa e real é tecnicamente viável, uma constatação que ressalta a necessidade de adoção proativa da IA para defesa.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).

Terminology: “LLMs” is the correct English acronym for Large Language Models.
