O Microsoft 365 tornou-se o centro da produtividade das organiza\u00e7\u00f5es. E-mails, ficheiros, Teams, SharePoint, OneDrive e informa\u00e7\u00e3o sens\u00edvel dos clientes est\u00e3o acess\u00edveis atrav\u00e9s de uma \u00fanica identidade. <\/strong><\/h3>\n[\/vc_column_text][vc_column_text css=”” text_direction=”default”]Por isso, as contas Microsoft 365 s\u00e3o atualmente um dos principais alvos dos cibercriminosos.
\nEmbora a autentica\u00e7\u00e3o multifator (MFA) seja essencial, os ataques evolu\u00edram significativamente. Atualmente, existem campanhas de phishing avan\u00e7adas capazes de contornar mecanismos de seguran\u00e7a ou explorar falhas humanas para obter acesso \u00e0s contas, comprometendo dados, comunica\u00e7\u00f5es e processos de neg\u00f3cio. <\/span>[\/vc_column_text][vc_column_text css=”” text_direction=”default”]\n

Como pode ajudar uma plataforma de prote\u00e7\u00e3o complementar?\u00a0\u00a0<\/strong><\/h3>\n

Uma solu\u00e7\u00e3o de seguran\u00e7a especializada para Microsoft 365 acrescenta uma camada adicional de prote\u00e7\u00e3o, combinando mecanismos avan\u00e7ados de dete\u00e7\u00e3o e monitoriza\u00e7\u00e3o. Estas plataformas s\u00e3o capazes de identificar tentativas de phishing e spear phishing com elevado grau de sofistica\u00e7\u00e3o, prevenir situa\u00e7\u00f5es de comprometimento de contas (Account Takeover) e detetar fraudes baseadas em usurpa\u00e7\u00e3o de identidade (impersonation).<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

Al\u00e9m disso, analisam comportamentos suspeitos e acessos an\u00f3malos, bloqueiam liga\u00e7\u00f5es maliciosas e anexos potencialmente perigosos, monitorizam continuamente as atividades de risco e permitem uma resposta r\u00e1pida a incidentes de seguran\u00e7a atrav\u00e9s de alertas em tempo real.<\/span>\u00a0<\/span><\/p>\n

O que pode acontecer sem esta prote\u00e7\u00e3o?\u00a0<\/strong><\/h3>\n

Alguns cen\u00e1rios bastante comuns que podem acontecer sem esta prote\u00e7\u00e3o:<\/span>\u00a0<\/span><\/p>\n

    \n
  • \u00a0<\/span>Um colaborador recebe um e-mail aparentemente enviado pelo diretor financeiro da empresa e, acreditando tratar-se de um pedido leg\u00edtimo, realiza uma transfer\u00eancia banc\u00e1ria fraudulenta.<\/span><\/li>\n
  • Uma conta de e-mail \u00e9 comprometida e utilizada para enviar mensagens maliciosas a clientes e parceiros, colocando em causa a confian\u00e7a e a reputa\u00e7\u00e3o da organiza\u00e7\u00e3o.<\/li>\n
  • Dados confidenciais armazenados no OneDrive ou SharePoint s\u00e3o copiados e exfiltrados sem serem detetados, expondo informa\u00e7\u00e3o cr\u00edtica do neg\u00f3cio.<\/li>\n
  • Um hacker<\/em> obt\u00e9m acesso a uma caixa de correio eletr\u00f3nico e cria regras ocultas para desviar mensagens importantes, mantendo-se invis\u00edvel durante longos per\u00edodos.<\/li>\n
  • Credenciais roubadas s\u00e3o utilizadas para lan\u00e7ar ataques internos, escalar privil\u00e9gios ou distribuir ransomware dentro da organiza\u00e7\u00e3o.\u00a0<\/span><\/li>\n<\/ul>\n

    Em muitos casos, o impacto s\u00f3 \u00e9 descoberto dias ou semanas mais tarde, quando j\u00e1 existem perdas financeiras, danos reputacionais ou incumprimentos legais.<\/span>\u00a0<\/span><\/p>\n

    \u00a0<\/span>Prote\u00e7\u00e3o dever\u00e1 ser uma prioridade estrat\u00e9gica\u00a0\u00a0<\/strong><\/p>\n

    A prote\u00e7\u00e3o das contas Microsoft 365 deve ser encarada como uma prioridade estrat\u00e9gica. A combina\u00e7\u00e3o de autentica\u00e7\u00e3o multifator (MFA), boas pr\u00e1ticas de utiliza\u00e7\u00e3o e uma plataforma especializada de prote\u00e7\u00e3o e monitoriza\u00e7\u00e3o permite reduzir significativamente o risco de fraude, roubo de dados e comprometimento de contas.<\/span>\u00a0<\/span><\/p>\n
