O AsyncRAT é um projeto que parece ter sido desenvolvido com propósitos educacionais, ou pelo menos é o que seu criador está reivindicando na sua página do GitHub. O código do AsyncRAT está disponível publicamente na página do GitHub mencionada anteriormente. Uma vez que os especialistas em malware revisaram o código, rapidamente ficou claro que o AsyncRAT pode servir como uma ferramenta muito ameaçadora se cair nas mãos de pessoas mal-intencionadas.

Capacidades

O AsyncRAT não é muito diferente da maioria dos RATs existentes, mas isso não o torna menos ameaçador. Essa ameaça é capaz de registrar as suas teclas, pois possui um módulo de keylogging. Isso geralmente é usado para coletar credenciais de login e outros dados confidenciais. O AsyncRAT também pode gravar vídeo através da webcam no sistema comprometido, bem como gravar áudios usando o microfone. Esse RAT também possui um recurso de roubo de informações, que permite que o AsyncRAT colete informações de serviços de mensagens, navegadores da Web e clientes FTP. Além disso, o AsyncRAT pode visualizar, baixar e fazer upload de arquivos no PC infectado, o que significa que ele pode não apenas coletar cópias dos seus arquivos, mas também plantar malwares adicionais.

O perigo real do AsyncRAT não é porque ele oculta as suas capacidades, mas o fato de que o seu criador disponibilizou publicamente essa ameaça. Isso significa que qualquer indivíduo mal-intencionado, mesmo aqueles com habilidades técnicas nulas, podem usar essa ameaça para causar grandes danos aos usuários desavisados. Um cenário ainda mais assustador é quando imaginamos que criminosos cibernéticos altamente qualificados podem usar o código do AsyncRAT e reforçar a ameaça para torná-la ainda mais ameaçadora. É hora dos usuários perceberem que precisam levara sua segurança cibernética muito a sério, pois ameaças como o AsyncRAT estão à espreita em toda a Web. Baixe e instale uma ferramenta anti-spyware genuína, que manterá as ameaças como o AsyncRAT sob controle e lhe darão tranqüilidade.
