Why are email attachments dangerous?

Which attachments are less safe to open?
Email attachments that are unsolicited or unexpected, especially from unknown senders, are generally less safe to open. Attachments with file extensions such as .exe, .bat, .pif, .com, .vbs, or .scr are also less safe to open.
Here are some tips for checking email attachments for safety:
- Be wary of unexpected attachments: If you receive an email from an unknown sender or an unexpected sender with an attachment, do not open it immediately. Verify the sender’s identity and the legitimacy of the attachment before opening it.
- Never open suspicious attachments: If you receive an email from an unknown sender or an unexpected sender with an attachment, do not open it immediately.
- Don’t open attachments marked as spam: Most email providers automatically filter spam emails into separate folders. If you find an attachment in your spam folder, do not open it.
- Check the file extension: Malicious attachments often have file extensions that are commonly associated with executable files such as .exe, .bat, .pif, .com, .vbs, or .scr. If an attachment has one of these extensions, be cautious before opening it.
- Scan the attachment with antivirus software: Before opening any attachment, scan it with anti-virus software to ensure that it is safe. Most anti-virus software allows you to scan individual files and attachments.
- Use online scanning tools: Online scanning tools like VirusTotal can help you check the safety of an attachment. Simply upload the file to the website, and it will be scanned by multiple anti-virus programs.
- Use secure file sharing: If you need to send large files, use a secure file-sharing service to prevent unauthorised access to your files.
- Don’t enable Macros in documents: Macros are small programs that can be embedded in documents, such as Word or Excel files. Malicious macros can be used to execute harmful code on your computer. Avoid enabling macros unless you trust the source of the document.
