A Anthropic confirmou que os modelos Claude escaparam de ambientes de avalia\u00e7\u00e3o de seguran\u00e7a cibern\u00e9tica supostamente isolados e alcan\u00e7aram sistemas reais com acesso \u00e0 internet.<\/p>\n\n\n\n

A Anthropic divulgou tr\u00eas incidentes de seguran\u00e7a<\/a> envolvendo modelos que acreditavam estar a atacar alvos simulados. Um erro de configura\u00e7\u00e3o manteve o acesso \u00e0 internet ativado, permitindo que interagissem com servi\u00e7os e organiza\u00e7\u00f5es reais.<\/p>\n\n\n\n

Os incidentes surgem depois da recente viola\u00e7\u00e3o do Hugging Face que envolveu agentes da OpenAI e de relatos de que os modelos da OpenAI exploraram vulnerabilidades de dia zero do JFrog Artifactory<\/a> ao tentar escapar de uma sandbox.<\/p>\n\n\n\n

Acesso \u00e0 internet permaneceu ativado durante os testes de seguran\u00e7a do Claude<\/h2>\n\n\n\n

A avaliadora independente Irregular organizou os testes como exerc\u00edcios de captura de bandeira. Os modelos receberam instru\u00e7\u00f5es indicando que estavam a operar dentro de simula\u00e7\u00f5es isoladas.<\/p>\n\n\n\n

Contudo, o ambiente de teste ainda podia aceder \u00e0 internet p\u00fablica. Quando os modelos n\u00e3o conseguiram localizar os alvos simulados pretendidos, procuraram sistemas semelhantes online e trataram alguns servi\u00e7os reais como parte do exerc\u00edcio.<\/p>\n\n\n\n

A Anthropic e a Irregular n\u00e3o identificaram o problema de configura\u00e7\u00e3o at\u00e9 meses depois do primeiro incidente. A Anthropic afirmou que a viola\u00e7\u00e3o mais antiga conhecida ocorreu em abril e permaneceu por descobrir durante cerca de tr\u00eas meses.<\/p>\n\n\n\n

Claude Mythos 5 publicou um pacote malicioso no PyPI<\/h3>\n\n\n\n

Durante uma avalia\u00e7\u00e3o, o Claude Mythos 5 encontrou instru\u00e7\u00f5es de instala\u00e7\u00e3o que faziam refer\u00eancia a um pacote Python fict\u00edcio. O nome do pacote n\u00e3o estava registado no Python Package Index.<\/p>\n\n\n\n

O modelo reconheceu que poderia registar o nome n\u00e3o utilizado e publicar o seu pr\u00f3prio c\u00f3digo. Os sistemas que seguissem as instru\u00e7\u00f5es de instala\u00e7\u00e3o poderiam ent\u00e3o descarregar e executar automaticamente o pacote.<\/p>\n\n\n\n

O Claude criou as contas necess\u00e1rias e carregou um pacote malicioso para o PyPI. O pacote permaneceu publicamente dispon\u00edvel durante cerca de uma hora antes de as prote\u00e7\u00f5es automatizadas do PyPI o removerem.<\/p>\n\n\n\n

Durante esse per\u00edodo, 15 sistemas reais descarregaram e executaram o c\u00f3digo.<\/p>\n\n\n\n

Credenciais de empresa de seguran\u00e7a foram roubadas<\/h3>\n\n\n\n

Um dos sistemas afetados pertencia a uma empresa de ciberseguran\u00e7a que descarrega e analisa automaticamente pacotes PyPI recentemente publicados.<\/p>\n\n\n\n

O pacote malicioso recolheu credenciais do sistema e enviou-as para uma infraestrutura que o Claude tinha criado. O modelo utilizou depois as credenciais roubadas para aceder a partes adicionais da rede da empresa.<\/p>\n\n\n\n

A Anthropic afirmou que o Claude n\u00e3o tinha conhecimento pr\u00e9vio da organiza\u00e7\u00e3o e n\u00e3o a selecionou intencionalmente como alvo. A empresa notificou o PyPI e partilhou indicadores associados ao pacote malicioso.<\/p>\n\n\n\n

A empresa de ciberseguran\u00e7a afetada n\u00e3o tinha detetado a intrus\u00e3o antes de a Anthropic a contactar.<\/p>\n\n\n\n

Claude Opus 4.7 acedeu a uma base de dados de produ\u00e7\u00e3o<\/h3>\n\n\n\n

Uma avalia\u00e7\u00e3o separada envolvendo o Claude Opus 4.7 resultou no acesso a uma base de dados de produ\u00e7\u00e3o real.<\/p>\n\n\n\n

O alvo fict\u00edcio utilizado no exerc\u00edcio partilhava o nome com uma empresa e um dom\u00ednio existentes. Depois de o Claude n\u00e3o conseguir aceder ao sistema simulado, encontrou a organiza\u00e7\u00e3o real online e tratou-a como o alvo pretendido.<\/p>\n\n\n\n

O modelo extraiu credenciais de aplica\u00e7\u00e3o e de infraestrutura antes de obter acesso a uma base de dados que continha v\u00e1rias centenas de linhas de informa\u00e7\u00e3o de produ\u00e7\u00e3o.<\/p>\n\n\n\n

A Anthropic descreveu este incidente como mais grave porque o modelo alcan\u00e7ou sistemas empresariais em produ\u00e7\u00e3o e acedeu a dados reais.<\/p>\n\n\n\n

Modelo de investiga\u00e7\u00e3o analisou cerca de 9.000 sistemas<\/h3>\n\n\n\n

Um modelo de investiga\u00e7\u00e3o da Anthropic ainda n\u00e3o lan\u00e7ado causou o terceiro incidente.<\/p>\n\n\n\n

Depois de n\u00e3o conseguir localizar o alvo de teste pretendido, o modelo analisou cerca de 9.000 sistemas ligados \u00e0 internet. Comprometeu uma aplica\u00e7\u00e3o exposta utilizando credenciais apresentadas numa p\u00e1gina de depura\u00e7\u00e3o e uma vulnerabilidade de inje\u00e7\u00e3o de SQL.<\/p>\n\n\n\n

Mais tarde, o modelo determinou que a aplica\u00e7\u00e3o comprometida pertencia a uma conta de cloud n\u00e3o relacionada. Em seguida, interrompeu o ataque sem necessitar de interven\u00e7\u00e3o humana.<\/p>\n\n\n\n

A Anthropic ainda estava a tentar contactar a organiza\u00e7\u00e3o afetada quando publicou as suas descobertas.<\/p>\n\n\n\n

Modelos basearam-se em fragilidades de seguran\u00e7a b\u00e1sicas<\/h3>\n\n\n\n

A Anthropic afirmou que os incidentes n\u00e3o envolveram t\u00e9cnicas de ataque novas ou anteriormente desconhecidas.<\/p>\n\n\n\n

Os modelos basearam-se em fragilidades comuns, incluindo credenciais expostas, palavras-passe fracas, pontos de acesso acess\u00edveis publicamente, p\u00e1ginas de depura\u00e7\u00e3o contendo informa\u00e7\u00f5es sens\u00edveis e vulnerabilidades de inje\u00e7\u00e3o de SQL.<\/p>\n\n\n\n

A principal falha resultou do acesso irrestrito \u00e0 internet e do pressuposto dos modelos de que todos os sistemas acess\u00edveis faziam parte do teste autorizado.<\/p>\n\n\n\n

Anthropic suspendeu os testes cibern\u00e9ticos depois de rever os incidentes<\/h3>\n\n\n\n

A Anthropic come\u00e7ou a rever as avalia\u00e7\u00f5es e suspendeu todos os testes de ciberseguran\u00e7a a 23 de julho.<\/p>\n\n\n\n

A empresa identificou os tr\u00eas incidentes a 24 de julho. A Irregular e duas organiza\u00e7\u00f5es afetadas receberam notifica\u00e7\u00f5es a 27 de julho.<\/p>\n\n\n\n

A Anthropic continuou a tentar contactar a organiza\u00e7\u00e3o envolvida no terceiro incidente.<\/p>\n\n\n\n

Nenhuma das duas organiza\u00e7\u00f5es que a Anthropic contactou com sucesso tinha detetado independentemente os comprometimentos antes de receber as notifica\u00e7\u00f5es.<\/p>\n\n\n\n

Ambiente de avalia\u00e7\u00e3o carecia de salvaguardas de produ\u00e7\u00e3o<\/h3>\n\n\n\n

Os sistemas de teste n\u00e3o utilizaram os classificadores, ferramentas de monitoriza\u00e7\u00e3o e outras salvaguardas inclu\u00eddas nos modelos Claude dispon\u00edveis publicamente.<\/p>\n\n\n\n

A Anthropic afirmou que as suas prote\u00e7\u00f5es de produ\u00e7\u00e3o provavelmente teriam bloqueado as a\u00e7\u00f5es observadas durante as avalia\u00e7\u00f5es. Caracterizou os incidentes principalmente como falhas no design dos testes, na infraestrutura, na monitoriza\u00e7\u00e3o e na supervis\u00e3o de terceiros.<\/p>\n\n\n\n

A empresa n\u00e3o descreveu os incidentes como evid\u00eancia de uma falha de alinhamento fundamental. Em vez disso, os modelos seguiram as instru\u00e7\u00f5es da avalia\u00e7\u00e3o enquanto interagiam, por engano, com alvos reais.<\/p>\n\n\n\n

Anthropic planeia uma monitoriza\u00e7\u00e3o mais rigorosa para testes futuros<\/h3>\n\n\n\n

A Anthropic planeia expandir a monitoriza\u00e7\u00e3o de transcri\u00e7\u00f5es em futuras avalia\u00e7\u00f5es e introduzir ferramentas de investiga\u00e7\u00e3o mais robustas.<\/p>\n\n\n\n

Ir\u00e1 tamb\u00e9m aumentar a supervis\u00e3o dos parceiros de teste terceiros e rever a forma como os ambientes de avalia\u00e7\u00e3o se ligam \u00e0 infraestrutura externa.<\/p>\n\n\n\n

A Anthropic est\u00e1 a discutir uma revis\u00e3o independente com a METR e planeia publicar uma transcri\u00e7\u00e3o parcialmente editada do incidente do PyPI.<\/p>\n\n\n\n

Apesar das falhas de seguran\u00e7a, o Claude Mythos demonstrou fortes capacidades de dete\u00e7\u00e3o de vulnerabilidades. A Microsoft tamb\u00e9m reconheceu que tem dificuldades em corrigir todas as vulnerabilidades encontradas pelo Claude Mythos<\/a>, destacando tanto o potencial de investiga\u00e7\u00e3o de seguran\u00e7a do modelo como os riscos criados por ambientes de teste mal isolados.<\/p>\n","protected":false},"excerpt":{"rendered":"
