Sloppy work, but I’m sure some people will fall for it.
Have you gotten an email message supposedly from email@example.com (but really from someone else)? A brief email with the ADP logo and an invoice.zip file attachment?
Don’t open it.
Although I don’t think opening the message will cause any harm, the attachment is likely some sort of virus — or contains one when opened — and that can’t be a good thing.
Here’s what the message I got looks like. Note the From field and the typo in the bold, underlined text.
I’ve said it before and I’ll say it again: Don’t open attachments you aren’t expecting, especially from organizations you don’t have some sort of email relationship with. Doing so is just plain stupid.
Coincidentally, I worked for ADP at their corporate headquarters back in the 1980s.
