Com a cont\u00ednua dissemina\u00e7\u00e3o de v\u00edrus de computador, h\u00e1 agora uma variedade de tipos diferentes de amea\u00e7as, como o ransomware<\/span><\/h2>\n

<\/p>\n

Os dispositivos eletr\u00f4nicos que s\u00e3o usados diariamente cont\u00eam uma grande quantidade de informa\u00e7\u00f5es que s\u00e3o protegidas por senhas. Entretanto, isto n\u00e3o impede um ataque cibern\u00e9tico por um v\u00edrus que poderia colocar esta informa\u00e7\u00e3o em risco.<\/span><\/p>\n

Este \u00e9 o caso do v\u00edrus conhecido como <\/span>ransomware<\/b>. \u00c9 um malware que ainda \u00e9 desconhecido para a maioria da popula\u00e7\u00e3o, mas que pode ser letal.\u00a0 Sua principal fun\u00e7\u00e3o \u00e9 impedir o acesso \u00e0s informa\u00e7\u00f5es armazenadas em um dispositivo a fim de destru\u00ed-lo ou dissemin\u00e1-lo.<\/span><\/p>\n

Sua dissemina\u00e7\u00e3o pode ocorrer por meio de campanhas de spam, configura\u00e7\u00f5es incorretas de software, atualiza\u00e7\u00f5es falsas, canais de download enganosos e muito mais.\u00a0\u00a0<\/span><\/p>\n

Caminhos para afetar o dispositivo<\/b><\/p>\n

Um dos m\u00e9todos que os cibercriminosos utilizam para afetar sua v\u00edtima \u00e9 explorar quaisquer lacunas na seguran\u00e7a do software. Os criadores deste v\u00edrus sabem com certeza onde se encontram as falhas no sistema de seguran\u00e7a.<\/span><\/p>\n

Outro m\u00e9todo \u00e9 fazer o login usando credenciais de acesso que s\u00f3 o administrador possui. Isto \u00e9 conseguido por meio de golpes como o phishing que \u00e9 frequentemente utilizado em contas falsas simulando a dos bancos.\u00a0<\/span><\/p>\n

Al\u00e9m disso, eles podem recorrer a e-mails falsos que cont\u00eam links para supostas faturas ou documentos, mas na verdade instalam o malware.<\/span><\/p>\n

Em rela\u00e7\u00e3o ao acima mencionado, outra rota frequentemente utilizada s\u00e3o os e-mails de spam que incluem sites ou arquivos contendo malware. Hoje em dia, os e-mails podem ser filtrados, mas muitas pessoas ainda acabam baixando o v\u00edrus.<\/span><\/p>\n

Formas de prote\u00e7\u00e3o<\/b><\/p>\n

Uma das principais recomenda\u00e7\u00f5es \u00e9 proteger o sistema o melhor poss\u00edvel e permanecer vigilante para n\u00e3o se deixar enganar pelos m\u00e9todos descritos acima. \u00c9 importante permanecer alerta e desconfiado das mensagens que voc\u00ea recebe, seja por e-mail, SMS, redes sociais, entre outros.<\/span><\/p>\n

Da mesma forma, uma boa estrat\u00e9gia \u00e9 segmentar redes ou <\/span>subnetting<\/span><\/i>. Isto evita a exposi\u00e7\u00e3o de servi\u00e7os internos e ajuda a reduzir a vulnerabilidade.<\/span><\/p>\n

Finalmente, cabe destacar que a <\/span>FUNIBER<\/b><\/a> patrocina in\u00fameros cursos para aprender mais sobre tecnologia e intelig\u00eancia artificial. Alguns destes programas s\u00e3o o <\/span>Mestrado em Dire\u00e7\u00e3o Estrat\u00e9gica em Engenharia de Software<\/b><\/a> e o <\/b>Mestrado em Dire\u00e7\u00e3o Estrat\u00e9gica em Tecnologias Software<\/span>.<\/b><\/a><\/p>\n
