“I was, like, huh, maybe there’s more we can do with this — actually get a list of all these profiles that have these results and use that to analyze the structure of which companies are helping with which programs, which people are helping with which programs, try to figure out in what capacity, and learn more about things that we might not know about,” McGrath said.
He set up a computer program called a scraper to search LinkedIn for public profiles that mention known NSA programs, contractors or jargon — such as SIGINT, the agency’s term for “signals intelligence” gleaned from intercepted communications. Once the scraper found the name of an NSA program, it searched nearby for other words in all caps. That allowed McGrath to find the names of unknown programs, too.
Once McGrath had the raw data — thousands of profiles in all, with 70 to 80 different program names — he created a network graph that showed the relationships between specific government agencies, contractors and intelligence programs. Of course, the data are limited to what people are posting on their LinkedIn profiles. Still, the network graph gives a sense of which contractors work on several NSA programs, which ones work on just one or two, and even which programs military units in Iraq and Afghanistan are using. And that is just the beginning.
