Dark web downloads
After wrapping up Project Cumulus, the latest in the Bitglass Where's Your Data series, we looked back at the results and developments from our first Where's You Data test conducted early in 2015. In the original experiment, we leaked spreadsheets with fake names, credit card numbers, Social Security numbers, addresses, and other personal information to both the surface web and the Dark Web. These spreadsheets were embedded with Bitglass watermark technology that would regularly call back to our researchers. We got hundreds of hits globally, including many from crime syndicates in Nigeria and Russia.
As the chart above reveals, downloads and new callbacks were few and far between in the eight months following the leak. We didn't expect the long quiet period to end, but in October 2015, we observed a spike in downloads of these old files.
