A tool called SNAP_R will be released at Black Hat by researchers from ZeroFOX. The tool runs through a target Twitter account to gather data on what topics seem to interest the subscriber. Then it writes a tweet loaded up with a link to a site containing malware and sends it to a victim. It takes five to 10 minutes to write a single spear phishing email, but it takes a matter of seconds or minutes to generate thousands of phishing tweets. The goal is for the tweets to be indistinguishable from tweets written by a person.”]
