O ataque a pacotes acompanhantes no reposit\u00f3rio NPM alcan\u00e7ou um novo n\u00edvel. Al\u00e9m do uso de malware para interceptar pagamentos e informa\u00e7\u00f5es confidenciais, os atacantes passaram a implantar um verme em pacotes comprometidos para automatizar a inje\u00e7\u00e3o de malware em depend\u00eancias. O uso do verme foi registrado ap\u00f3s a comprometimento do pacote NPM @ctrl\/tinycolor, que possui 2,2 milh\u00f5es de downloads semanais e \u00e9 uma depend\u00eancia direta de 964 pacotes. Como resultado da atividade do verme, o ataque afetou 187 pacotes, para os quais foram criadas vers\u00f5es maliciosas (477 vers\u00f5es maliciosas). <\/p>\n

Durante um novo ataque, ap\u00f3s obter informa\u00e7\u00f5es da conta do acompanhante por meio de phishing, os atacantes publicam uma vers\u00e3o de pacote com um verme que \u00e9 ativado ao instalar o pacote comprometido entre as depend\u00eancias. Ap\u00f3s a ativa\u00e7\u00e3o, o verme busca credenciais no ambiente atual, carregando e executando a ferramenta TruffleHog. Se um token de conex\u00e3o ao diret\u00f3rio NPM for encontrado, o verme publica automaticamente uma nova vers\u00e3o maliciosa e compromete em cadeia a \u00e1rvore de depend\u00eancias. Al\u00e9m do token de acesso ao NPM, o verme captura chaves de acesso ao GitHub e a servi\u00e7os de nuvem como AWS, Azure e GCP (Google Cloud Platform), juntamente com outros dados confidenciais que o scanner TruffleHog pode descobrir. <\/p>\n

Vers\u00f5es maliciosas s\u00e3o criadas para os 20 pacotes mais populares, aos quais o token NPM encontrado tem acesso. A funcionalidade de publica\u00e7\u00e3o de vers\u00e3o \u00e9 implementada na forma da fun\u00e7\u00e3o NpmModule.updatePackage, que carrega o arquivo de origem do pacote, altera o n\u00famero da vers\u00e3o e adiciona um gancho postinstall no arquivo package.json, insere o manipulador bundle.js, reempacota o pacote e o publica. A opera\u00e7\u00e3o \u00e9 suportada em Linux e macOS. <\/p>\n

O verme recebeu o codinome Shai-Hulud (um verme gigantesco mencionado no romance Duna). As credenciais encontradas no sistema s\u00e3o publicadas no GitHub por meio da cria\u00e7\u00e3o de reposit\u00f3rios nomeados Shai-Hulud (por exemplo, «B611\/Shai-Hulud»), e tamb\u00e9m s\u00e3o refletidas em forma codificada nos logs do GitHub Actions. No reposit\u00f3rio criado, h\u00e1 um arquivo data.json, que cont\u00e9m uma string com informa\u00e7\u00f5es da sistema, vari\u00e1veis de ambiente e chaves de acesso interceptadas, codificadas com o m\u00e9todo base64. No CI baseado no GitHub, para transmitir informa\u00e7\u00f5es para um host externo, o verme cria um manipulador do GitHub Actions (.github\/workflows\/shai-hulud-workflow.yml). Aparentemente, o ataque n\u00e3o se limita aos mencionados 187 pacotes, pois novos reposit\u00f3rios com o nome Shai-Hulud e o arquivo data.json continuam surgindo no GitHub.

\"Um<\/center> <\/p>\n

Entre outras coisas, como resultado da atividade do verme, 25 pacotes da empresa CrowdStrike, que desenvolve ferramentas para proteger contra ataques<\/a> atrav\u00e9s de depend\u00eancias (Supply Chain). Segundo a CrowdStrike, os pacotes comprometidos n\u00e3o foram utilizados na plataforma Falcon e o ataque n\u00e3o se espalhou para os clientes. Tamb\u00e9m foi revelado que a onda anterior de publica\u00e7\u00e3o de lan\u00e7amentos maliciosos no NPM, realizada sem o verme, afetou o projeto gemini-cli, desenvolvido pela Google.
