Voila pourquoi il ne faut pas transmettre un RIB par messagerie sans une protection par mot de passe.<\/p>\n

Et apr\u00e8s l’histoire qu’on m’a racont\u00e9, vous serez convaincu.<\/p>\n

Apr\u00e8s une demande de devis pour travaux par un artisan, la personne re\u00e7oit par mail, le devis et le RIB pour verser un acompte de 30%, c’est la r\u00e8gle habituelle.<\/em>
\nEnvoi du virement.<\/em>
\nQuelques jours apr\u00e8s l’artisan t\u00e9l\u00e9phone parce qu’il n’a pas re\u00e7u le virement.<\/em>
\nCelui-ci (le virement) a \u00e9t\u00e9 envoy\u00e9 \u00e0 un destinataire crapuleux.<\/em>
\nComment est-ce possible ?
\nLe mail \u00e0 \u00e9t\u00e9 intercept\u00e9 et le RIB modifi\u00e9 !<\/p>\n

M\u00eame si votre banque est compr\u00e9hensible, n’esp\u00e9rez pas \u00eatre rembours\u00e9 int\u00e9gralement. Et 30% d’une certaine somme \u00e7a peut \u00eatre beaucoup…<\/p>\n

Il y a, bien s\u00fbr, une possibilit\u00e9 d’\u00e9chapper \u00e0 ce genre de probl\u00e8me. Il suffit de crypter les documents sensibles, ce que personne ne fait.
\nCrypter, c’est ajouter un mot de passe pour ouvrir le document, on parle aussi de chiffrement. Surtout ne pas communiquer le mot de passe dans le m\u00eame message. Le mieux est de renseigner par une autre voie que le mail.<\/p>\n

S\u00e9curisation du document<\/strong>
\n\u2022 Sur Android<\/em><\/strong> :
\nhttp:\/\/play.google.com\/store\/apps\/details?id=pdf.shash.com.pdfutility<\/a><\/p>\n

\u2022 Sur Windows<\/em><\/strong> il y a PDFCreator<\/a>, l’imprimante virtuelle qui transforme votre document ou image en fichier pdf.
\n\u2022 Pas \u00e0 pas<\/em><\/strong>
\n1. Ouvrir le document pdf \u00e0 crypter avec pdfcreator (clic droit)
\n2. Choisir le profil de s\u00e9curisation avec un cadenas \u00e0 droite
\n3. Sauvegarder et choisir les mots de passe<\/p>\n

S\u00e9curisation du mail<\/strong>
\nOn peut aussi passer par une application de messagerie crypt\u00e9e. ProtonMail par exemple https:\/\/humm.loverde.fr\/?p=9225<\/a>.<\/p>\n

Le destinataire n’a pas besoin de l’application ni d’\u00eatre inscrit. L’indice (hint) n’est pas obligatoire, l’envoi du mot de passe peut se faire par une autre voie.<\/p>\n
