Especialistas da Trustwave, que atua na \u00e1rea de seguran\u00e7a da informa\u00e7\u00e3o, relataram a descoberta de uma grande campanha de envio de mensagens de spam utilizadas para baixar nos PCs das v\u00edtimas um ransomware disfar\u00e7ado de atualiza\u00e7\u00f5es do sistema operacional Windows.<\/p>\n

\"Atualiza\u00e7\u00f5es<\/p>\n

A Microsoft nunca envia e-mails notificando sobre a necessidade de atualizar o Windows. \u00c9 claro que a nova campanha de dissemina\u00e7\u00e3o de malware visa pessoas que n\u00e3o est\u00e3o cientes disso.<\/p>\n

A fonte informa que os usu\u00e1rios est\u00e3o recebendo mensagens com o t\u00edtulo \u201cInstale a atualiza\u00e7\u00e3o mais recente do Microsoft Windows agora mesmo!\u201d ou \u201cAtualiza\u00e7\u00e3o cr\u00edtica do Microsoft Windows!\u201d. O texto do e-mail menciona a necessidade de instalar rapidamente as atualiza\u00e7\u00f5es importantes do Windows, que alegadamente est\u00e3o anexadas \u00e0 mensagem. A mensagem realmente cont\u00e9m um arquivo anexado, que parece uma imagem no formato JPG, mas na verdade \u00e9 um arquivo execut\u00e1vel .NET. Se voc\u00ea recebeu um e-mail semelhante, n\u00e3o deve de forma alguma abrir esse arquivo, pois isso pode levar a consequ\u00eancias graves.<\/p>\n

\"Atualiza\u00e7\u00f5es<\/p>\n

O fato \u00e9 que o arquivo anexado \u00e0 mensagem \u00e9 um ransomware Cyborg, que ir\u00e1 criptografar todos os arquivos do usu\u00e1rio, bloqueando seu conte\u00fado e mudando a extens\u00e3o para .777. Assim como outros ransomwares, o usu\u00e1rio receber\u00e1 um arquivo de texto Cyborg_DECRYPT.txt, que cont\u00e9m instru\u00e7\u00f5es sobre como descriptografar os arquivos. N\u00e3o \u00e9 dif\u00edcil adivinhar que ao usu\u00e1rio \u00e9 oferecido pagar pela descriptografia, mas n\u00e3o deve se apressar em faz\u00ea-lo, pois n\u00e3o h\u00e1 garantia de que isso ajudar\u00e1.<\/p>\n

<\/center><\/p>\n

Os especialistas recomendam ter cuidado com e-mails desconhecidos que chegam de pessoas e organiza\u00e7\u00f5es desconhecidas. \u00c9 preciso estar atento e n\u00e3o abrir arquivos anexados se voc\u00ea n\u00e3o tem certeza de sua origem.  <\/p>\n
