Enquanto os colaboradores passaram os \u00faltimos meses preocupados em se adaptar ao home office<\/a>, manter a produtividade e entregar os resultados em dia, criminosos exploravam as vulnerabilidades de seguran\u00e7a no sistema operacional e nos softwares para cometer ataques cibern\u00e9ticos milion\u00e1rios.<\/span><\/p>\n O passo a passo de criptografia de arquivos, sequestro de dados e bloqueio dos sistemas se repetiu em muitas organiza\u00e7\u00f5es ao redor do mundo. Sob o nome de ransomware, esse tipo de crime que j\u00e1 citamos no blog<\/a> est\u00e1 evoluindo rapidamente e tem como alvo principal as empresas respons\u00e1veis pelo fornecimento de servi\u00e7os essenciais, como \u00e1gua, energia, \u00f3leo e g\u00e1s.<\/span><\/p>\n De Copel, Eletrobras e Tribunal de Justi\u00e7a do Rio Grande do Sul<\/a> at\u00e9 Colonial Pipeline<\/a>, maior oleoduto dos Estados Unidos, institui\u00e7\u00f5es do setor p\u00fablico e privado sofrem com extors\u00f5es e custo m\u00e9dio de recupera\u00e7\u00e3o p\u00f3s-golpe cada vez mais alto. Como revelado na pesquisa \u201cState of Ransomware 2021\u201d<\/a> o valor m\u00e9dio dos regates ultrapassou um milh\u00e3o de d\u00f3lares.<\/span><\/p>\n Apesar de abra\u00e7ar a inova\u00e7\u00e3o e investir na transforma\u00e7\u00e3o digital para garantir a continuidade dos neg\u00f3cios em 2020, mais da metade dos tomadores de decis\u00e3o de empresas de m\u00e9dio porte espalhadas por 30 pa\u00edses ainda acreditam que esse tipo de ataque \u00e9 muito avan\u00e7ado para sua equipe de TI lidar.<\/span><\/p>\n Estrat\u00e9gias de seguran\u00e7a comuns para ataques cada vez mais aprimorados <\/strong><\/span><\/p>\n Para n\u00f3s aqui da Populos<\/a>, esses dados soam como sinal de alerta. Se mais de 74% dos CEOs e CIOs querem autorizar em larga escala o trabalho remoto permanente, \u00e9 preciso lembrar que os usu\u00e1rios s\u00e3o pe\u00e7as fr\u00e1geis. Cometendo erros intencionais ou n\u00e3o, eles podem ser porta de entrada para muitas amea\u00e7as. Por isso, combinar detec\u00e7\u00e3o, preven\u00e7\u00e3o e recupera\u00e7\u00e3o \u00e9 uma estrat\u00e9gia t\u00e3o importante.<\/span><\/p>\n Extremamente eficaz, essa amea\u00e7a exige das equipes de TI aten\u00e7\u00e3o redobrada ao comportamento dos usu\u00e1rios para identificar anomalias, falhas em autentica\u00e7\u00f5es, aumento de tr\u00e1fego e atualiza\u00e7\u00f5es constantes. Tudo isso ao mesmo tempo em que h\u00e1bitos de preven\u00e7\u00e3o, como aplica\u00e7\u00e3o de pol\u00edticas de senhas fortes, segmenta\u00e7\u00e3o de redes, prote\u00e7\u00e3o de endpoints, restri\u00e7\u00e3o de acesso e treinamento de funcion\u00e1rios s\u00e3o colocados em pr\u00e1tica.<\/span><\/p>\n Amplamente divulgado como parte desse plano de seguran\u00e7a digital, o backup tamb\u00e9m tem um papel muito importante para prote\u00e7\u00e3o de dados e garantia da continuidade das atividades nos ambientes empresariais. Inclusive, ao seguir a regra 3-2-1 e fazer tr\u00eas c\u00f3pias de seus backups, duas delas em locais de armazenamento diferentes e uma delas fora do local, os resultados costumam ser mais r\u00e1pidos durante a recupera\u00e7\u00e3o p\u00f3s-desastre.<\/span><\/p>\n Mas, \u00e9 preciso refor\u00e7ar que nem quando colocamos todas essas a\u00e7\u00f5es em pr\u00e1tica \u00e9 poss\u00edvel garantir 100% de prote\u00e7\u00e3o contra ransomware.
