There are a few important precautions to take when encountering suspicious links or attachments:

• Be cautious of any unexpected emails, regardless of who they coming from.
• Examine the link itself. Do not open the link or attachment if it looks suspicious. This can be determined by comparing the content of the email to what's displayed in the link.
• Be aware of the danger of malicious websites. Even if the link looks legitimate, it could redirect you to malware.
• If you do open an attachment, make sure your device is up to date with antivirus software.
• Verify the safety of any embedded links in the attachment by calling the sender or by independently researching the link.
• Be aware of social engineering techniques like phishing emails.
