Com a MFA ativa, o atacante que tem a sua palavra-passe tenta entrar repetidamente. Cada tentativa gera um pedido de aprovação no telemóvel. À terceira ou quarta, muita gente aprova só para parar o aviso. É a fadiga de MFA.
Como se proteger
- Nunca aprovar um pedido que não iniciou. Recuse e mude a palavra-passe.
- Ativar a correspondência de número (o utilizador tem de escrever o número mostrado no ecrã).
- Preferir apps de autenticação ou chaves de segurança a SMS.
- Limitar tentativas e alertar sobre inícios de sessão invulgares (geolocalização, hora).
- Dizer à equipa que avisar é sempre melhor do que aprovar.
