I just got this email from Hefty to open a link to an invoice. I haven't ordered anything from them in a long while (over a year). It looks like a virus to me, just a warning to anyone that also might get it.
From their FB: "If you received an email from us entitled "INVOICE FOR YOUR REVIEW" please do not open the link in the email. Our email server was compromised. We have taken all precautions against such attach but they made it though our security. We take the security of our customer information very seriously. No other customer information was compromised and all security protocols have been reinforced. Sorry for the inconvenience.
FYI: We will never send emails asking for personal information or with links requiring you to enter your personal passwords and email addresses, CC info, SSN, or any other information. If you receive an email like this please contact our office immediately so that we can deal with the situation."
