What are phishing messages?

Phishing is a type of attack that uses social engineering techniques to capture sensitive information from a victim via email.

- When this technique is used via SMS, it is called smishing, and when used via telephone (voice), it is called vishing.
- This technique can also be used via instant messaging on social media applications.

What to do?

- Do not click on attachments or links in suspicious emails, instant messages, or text messages;
- When contacted, confirm the authenticity of the email address, profile, or phone number of origin;
- Always evaluate the appropriateness of the content of emails, instant messages, text messages, or phone calls;
- Do not share personal data or follow instructions without checking the authenticity of the request with other sources—for example, with your bank account manager or a superior;
- Be wary of messages with formal language errors, but also do not trust all messages just because they do not contain formal language errors;
- In organizations, carry out simulations of phishing and smishing attacks, and possibly vishing attacks, in order to raise awareness and increase vigilance regarding these methods;
- Do not share sensitive data on social media, as this practice can provide information to potential attackers who want to carry out spear phishing (phishing targeted at a specific person);
- Report to the organization’s IT security managers or the authorities whenever you are the target or victim of such an attack;
- Be alert and do not allow yourself to be persuaded without reflection by authoritative requests, promises, or urgent requests.

How to create and add an email signature in Outlook Classic?

PT

1. Open a new email message.
2. On the Message menu, select Signature > Signatures.
  - Depending on the size of your classic Outlook window and whether you’re composing a new email message or a reply or forward, the Message menu and the Signature button might be in two different locations.
3. Under Select signature to edit, choose New, and in the New Signature dialog box, type a name for the signature.
4. Under Edit signature, compose your signature. You can change fonts, font colors, and sizes, as well as text alignment. If you want to create a more robust signature with bullets, tables, or borders, use Word to create and format your signature text, then copy and paste it into the Edit signature box. You can also use a pre-designed template to create your signature. Download the templates in Word, customize with your personal information, and then copy and paste into the Edit signature box.
5. Under Choose default signature, set the following options:
  - In the E-mail account drop-down box, choose an email account to associate with the signature. You can have different signatures for each email account.
  - You can have a signature automatically added to all new messages. Go to in the New messages drop-down box and select one of your signatures. If you don’t want to automatically add a signature to new messages, choose (none). This option does not add a signature to any messages you reply to or forward.
6. You can select to have your signature automatically appear in reply and forward messages. In the Replies/forwards drop-down, select one of your signatures. Otherwise, accept the default option of (none).
7. Choose OK to save your new signature and return to your message. Classic Outlook doesn’t add your new signature to the message you opened in Step 1, even if you chose to apply the signature to all new messages. You’ll have to add the signature manually to this one message. All future messages will have the signature added automatically. To add the signature manually, select Signature from the Message menu and then pick the signature you just created.
