Foi registrada uma comprometimento da extens\u00e3o oficial Claude Code para o VS Code, fornecida pela Anthropic e que conta com 63 milh\u00f5es de downloads. Os atacantes conseguiram inserir no diret\u00f3rio Open-VSX a vers\u00e3o antropic.claude-code@2.1.313, que continha c\u00f3digo malicioso para acesso remoto ao sistema do usu\u00e1rio. A publica\u00e7\u00e3o da vers\u00e3o maliciosa do pacote no reposit\u00f3rio da Microsoft n\u00e3o foi confirmada, mas um relat\u00f3rio com um aviso foi gerado para ela. Atualmente, a vers\u00e3o problem\u00e1tica foi removida do reposit\u00f3rio Open-VSX e uma vers\u00e3o corrigida 2.1.314 foi publicada em seguida.<\/p>\n

O c\u00f3digo para carregar componentes maliciosos foi adicionado ao in\u00edcio do arquivo extension.js e ativado durante a inicializa\u00e7\u00e3o do complemento ap\u00f3s o lan\u00e7amento do VS Code (n\u00e3o era necess\u00e1ria a intera\u00e7\u00e3o do usu\u00e1rio com Claude para ativar o c\u00f3digo malicioso). A atividade maliciosa se limitou \u00e0 cria\u00e7\u00e3o do diret\u00f3rio ~\/.ssh e \u00e0 adi\u00e7\u00e3o de uma chave p\u00fablica ssh-ed25519 ao arquivo ~\/.ssh\/authorized_keys com a anota\u00e7\u00e3o \u00absvc-telemetry\u00bb. Ap\u00f3s isso, foi feita a verifica\u00e7\u00e3o da presen\u00e7a do processo em segundo plano sshd no Linux e macOS, ativando o servidor SSH na aus\u00eancia dele. No Windows, foi realizada a instala\u00e7\u00e3o do OpenSSH via PowerShell. <\/p>\n

Em seguida, o c\u00f3digo malicioso salvou a chave privada em um arquivo tempor\u00e1rio chamado \u00ab.stk_*\u00bb e configurou um t\u00fanel reverso com um servidor SSH externo 134.209.82.225 para acesso remoto, executando ssh com as op\u00e7\u00f5es \u00ab-N -R \u2018*:0:localhost:22\u2019\u00bb. A conex\u00e3o era atualizada a cada 60 segundos. Scripts para atualizar o t\u00fanel e enviar dados para o externo servidores<\/a> eram salvos nos arquivos ~\/.config\/.smt e ~\/.config\/.smtk. A execu\u00e7\u00e3o peri\u00f3dica no Linux era configurada atrav\u00e9s do cron, no macOS atrav\u00e9s do LaunchAgent (com.apple.sysmond.plist), e no Windows atrav\u00e9s do SysMon e inicializa\u00e7\u00e3o autom\u00e1tica.<\/p>\n

Al\u00e9m disso, informa\u00e7\u00f5es sobre o nome do host, usu\u00e1rios registrados, sistema operacional, diret\u00f3rio inicial, e-mail (via git config \u2014global user.email) e vari\u00e1veis de ambiente com nomes contendo as palavras KEY, TOKEN, SECRET, PASS, AWS e GCP eram coletadas no sistema. Os dados coletados eram enviados no formato JSON para a URL http:\/\/134.209.82.225:8099\/beacon.<\/p>\n

Os usu\u00e1rios da extens\u00e3o Claude Code para o VS Code s\u00e3o aconselhados a verificar seus sistemas para a instala\u00e7\u00e3o da vers\u00e3o maliciosa 2.1.313. Indicadores de comprometimento do sistema incluem a presen\u00e7a dos arquivos ~\/.config\/.smt, ~\/.config\/.smtk, ~\/Library\/LaunchAgents\/com.apple.sysmond.plist, ${TMPDIR}\/.stk_*, ~\/.config\/smt.cmd,
\n~\/config\/smtk, SysMon e sysmon.cmd, bem como acessos pelas portas 22 e 8099 a endere\u00e7o IP<\/a> 134.209.82.225, e envio de solicita\u00e7\u00f5es HTTP\/HTTPS para os hosts ifconfig.me e api.ipify.org.<\/p>\n

N\u00e3o est\u00e1 claro como os invasores conseguiram inserir c\u00f3digo malicioso no complemento, mas acredita-se que a conta de um funcion\u00e1rio da Anthropic respons\u00e1vel pela manuten\u00e7\u00e3o do pacote possa ter sido hackeada ou que uma vulnerabilidade no sistema de publica\u00e7\u00e3o de vers\u00f5es tenha sido explorada.
