I have a client getting similar type zombie traffic. According to analytics, the traffic comes from organic traffic with exact match keywords. It looks something like "keyword" and time on site is 0, bounce rate is 100. We're are getting over a hundred thousand of these per month with all kinds of keywords. Nothing unusual from a OS, browser, IP, etc... perspective that would single out the source.
Obviously this makes traffic stats look great for SEO, but conversion is in the toilet. We don't know what to make of it other than some kind of bot. I have been wondering if it's been the pre-fetch feature on Google and other programs.
