Ao fazer isso, o invasor pode interceptar, ler ou modificar dados que a v\u00edtima acredita serem seguros. Isso ocorre sem que o usu\u00e1rio saiba que suas informa\u00e7\u00f5es est\u00e3o sendo comprometidas.<\/p>\n<h2>Hist\u00f3ria da origem do ataque de remo\u00e7\u00e3o de SSL<\/h2>\n<p>O termo \u201cremo\u00e7\u00e3o de SSL\u201d foi cunhado pela primeira vez por um pesquisador de seguran\u00e7a chamado Moxie Marlinspike na confer\u00eancia Black Hat Briefings em 2009. Marlinspike demonstrou como o ataque poderia ser executado para comprometer conex\u00f5es HTTPS seguras. A remo\u00e7\u00e3o de SSL faz parte de uma categoria mais ampla de ataques que aproveitam os pontos fracos na implementa\u00e7\u00e3o de protocolos SSL\/TLS.<\/p>\n<h2>Informa\u00e7\u00f5es detalhadas sobre ataque de remo\u00e7\u00e3o de SSL<\/h2>\n<h3>SSL e sua import\u00e2ncia<\/h3>\n<p>SSL (Secure Sockets Layer) \u00e9 um protocolo padr\u00e3o para proteger a comunica\u00e7\u00e3o em rede, geralmente implementado como HTTPS em navegadores da web.
