i. To preview an attachment in OneNote, follow these steps:
Open the notebook that contains the attachment.
Click on the page that contains the attachment.
Click on the attachment to select it.
A preview of the attachment will appear in the toolbar above the page.
If you want to open the attachment in its original application, you can do so by clicking on the "Open" button in the toolbar.
Here are some additional things to keep in mind when previewing attachments in OneNote:
Not all attachments can be previewed. For example, you cannot preview attachments that are password-protected or that are in a format that OneNote does not support.
If you are previewing a large attachment, it may take a few moments for the preview to load.
If you are previewing a file that contains sensitive information, you may want to consider opening the file in its original application instead of previewing it in OneNote.
ii. Here are some tips on how to recognize risky OneNote links:
Be suspicious of links that come from unknown sources. If you receive a link in an email or on a website from someone you don't know, don't click on it.
Beware of links that are shortened. Shortened links are often used to hide the true destination of the link. If you see a shortened link, hover over it to see the full URL before clicking on it.
Be careful of links that contain misspellings or grammatical errors. This is a common sign that the link is not legitimate.
Do not click on links that promise something for nothing. If a link promises you free money, a free gift, or something else that seems too good to be true, it probably is.
Use a security solution that can scan links for malware. A good security solution can help to protect you from malware that is embedded in links.
If you are unsure whether or not a link is safe, it is best to err on the side of caution and not click on it.

Be careful of attachments that are large in size. Large attachments can take a long time to download and can also be more likely to contain malware.
Do not open attachments that are in a format that you do not recognize. If you are not sure what type of file an attachment is, do not open it.

iv. Here is a case of OneNote malware affection:
In December 2022, a new malware campaign was discovered that was abusing Microsoft OneNote documents to deliver malware. The campaign was targeting a variety of industries, including government, healthcare, and education.
The malware was being delivered in OneNote documents that were attached to emails. The emails were disguised to look like they were from legitimate sources, such as government agencies or companies. The documents themselves were also disguised to look like they were legitimate, such as invoices or reports.
When a user opened the malicious OneNote document, it would execute a macro that would download and install malware on the user's computer. The malware could then be used to steal personal information, such as credit card numbers and passwords, or to take control of the user's computer.
Microsoft has since released a security update that patches the vulnerability that was being exploited by this malware campaign. However, it is important to be aware of this type of malware and to take steps to protect yourself.
