Would you just give your bank account information to anyone who called you up and asked for it? Probably not. For the same reason, you wouldn’t just download attachments from your email messages without a second thought. This can be a dangerous practice, as some of the most common threats nowadays spread themselves via unwanted email attachments. It’s important that you can identify when it’s the right time to download an attachment, and when it’s best to just leave it be without exposing your business to unnecessary risk.
