Les piratages de bo\u00eetes mail se multiplient ces derni\u00e8res ann\u00e9es. Tout commence souvent par une attaque de phishing : un lien, une demande de connexion, et hop, vous saisissez vos identifiants\u2026 qui tombent entre les mains du pirate.<\/p>\n\n\n\n

Des arnaques toujours plus difficiles \u00e0 d\u00e9tecter<\/strong>
Si les utilisateurs deviennent plus vigilants, les fraudeurs, eux, s\u2019adaptent. Gr\u00e2ce \u00e0 l\u2019intelligence artificielle, les arnaques sont d\u00e9sormais presque ind\u00e9tectables : aucune faute d\u2019orthographe, des chartes graphiques impeccables, des copies conformes de sites officiels. R\u00e9sultat : la m\u00e9fiance ne suffit plus, il faut aussi changer ses r\u00e9flexes.<\/p>\n\n\n\n

\n\n\n\n

Comment rep\u00e9rer les tentatives de piratage ?<\/strong><\/h3>\n\n\n\n

1. M\u00e9fiez-vous de tout ce qui sort de l\u2019ordinaire<\/strong><\/p>\n\n\n\n

    \n
  • Factures partag\u00e9es<\/strong> : Si un fournisseur vous envoie une facture via un lien de partage alors qu\u2019il l\u2019envoie habituellement en pi\u00e8ce jointe, v\u00e9rifiez. Pourquoi partager un fichier de quelques centaines de ko ? Appelez votre contact pour confirmer.<\/li>\n\n\n\n
  • Demande de modification d\u2019IBAN<\/strong> : Un mail vous demande de changer un RIB ? Ne validez rien sans avoir appel\u00e9 votre interlocuteur via un num\u00e9ro de t\u00e9l\u00e9phone connu<\/strong> (site web officiel, base client, etc.). Jamais<\/strong> celui indiqu\u00e9 dans le mail suspect.<\/li>\n<\/ul>\n\n\n\n

    2. Attention aux pi\u00e8ges de confirmation<\/strong>
    Certains pirates utilisent des techniques d\u00e9tourn\u00e9es pour obtenir votre consentement :<\/p>\n\n\n\n

      \n
    • Vous recevez un lien de partage, on vous demande votre adresse mail, un code vous est envoy\u00e9 par mail, et on vous invite \u00e0 le saisir sur une page de connexion.
      \u2192 C\u2019est \u00e9quivalent \u00e0 saisir votre mot de passe.<\/strong> Ne le faites pas sans certitude sur l’origine du mail.<\/li>\n<\/ul>\n\n\n\n

      3. V\u00e9rifiez syst\u00e9matiquement le nom de domaine<\/strong><\/p>\n\n\n\n

        \n
      • Un site frauduleux peut imiter \u00e0 la perfection l\u2019apparence d\u2019un site officiel. V\u00e9rifiez toujours l\u2019URL.<\/strong><\/li>\n\n\n\n
      • M\u00e9fiez-vous des noms de domaine trompeurs : par exemple, rnicrosoft.com<\/em> (avec un \u00ab r \u00bb et un \u00ab\u00a0n\u00a0\u00bb) au lieu de microsoft.com<\/em> (avec un \u00ab\u00a0m\u00a0\u00bb). \u00c0 premi\u00e8re vue, la diff\u00e9rence est imperceptible.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        Les bonnes pratiques \u00e0 adopter<\/strong><\/h3>\n\n\n\n

        Sensibilisez votre entourage<\/strong> : Partagez ces conseils avec vos coll\u00e8gues, amis ou famille. La vigilance collective est la meilleure protection.<\/p>\n\n\n\n

        Oubliez les id\u00e9es re\u00e7ues<\/strong> : Un mail frauduleux n\u2019est plus forc\u00e9ment mal \u00e9crit ou mal con\u00e7u. Les pirates reproduisent d\u00e9sormais des copies parfaites.<\/p>\n\n\n\n

        Ne cliquez pas, v\u00e9rifiez<\/strong> : En cas de doute, contactez directement la personne ou l\u2019entreprise concern\u00e9e, par un canal s\u00fbr<\/strong> (t\u00e9l\u00e9phone, site officiel, etc.).<\/p>\n\n\n\n

        Les messageries professionnelles disposent de param\u00e8tres de s\u00e9curit\u00e9 par d\u00e9faut (Transferts non autoris\u00e9s vers un domaine ext\u00e9rieur, limite d’envois par jour, etc…). Laissez ces param\u00e8tres de s\u00e9curit\u00e9 par d\u00e9faut<\/strong> m\u00eame si une application m\u00e9tier exige le retrait de ce param\u00e8tre.<\/p>\n\n\n\n
