Are there any existing data sets of spear phishing emails available?
I've found a bunch of data sets of phishing emails, but that's not what I'm looking for. I'm not looking for mass phishing campaigns. Rather, I'm interested in spear phishing: targeted social engineering emails. I've checked phishing archives, like Phishtank, but haven't found any that have separated out the ones that are targeted. My goal is to study what real spear phishing emails, as observed in the wild, look like.
