EFF:  Turns out, the DEA and FBI may know what medical conditions you have, whether you are having an affair, where you were last night, and more—all without any knowing that you have ever broken a law. That’s because the DEA and FBI, as part of over 1000 analysts at 23 U.S. intelligence agencies, have the ability to peer over the NSA’s shoulder and see much of the NSA’s metadata with ICREACH. Metadata is transactional data about communications, such as numbers dialed, email addresses sent to, and duration of phone calls, and it can be incredibly revealing. ICREACH, exposed by a release of Snowden documents in The Intercept, is a system that enables sharing of metadata by “provid[ing] analysts with the ability to perform a one-stop search of information from a wide variety of separate databases.” It’s the latest in a string of documents that demonstrate how little the intelligence community distinguishes between counter-terrorism and ordinary crime—and just how close to home surveillance may really be. The documents describe ICREACH as a “one-stop shopping tool for consolidated communications metadata analytic needs.” ICREACH brings together various databases with a single search query, allowing analysts to search literally billions of records. The tool allows sharing of “more than 30 different kinds of metadata on emails, phone calls, faxes, internet chats, and text messages, as well as location information collected from cellphones.” It is intended to include data from Five Eyes partners as well. While the program shares data obtained under Executive Order 12333, it includes data from U.S. persons. ICREACH grew out of CRISSCROSS and PROTON, older tools that allowed the CIA, DEA, FBI, DIA, and NSA to share metadata. Metadata sharing in CRISSCROSS started with only date, time, duration, calling number, and called number. PROTON, which expanded CRISSCROSS, allowed sharing of far more information, including latitude and longitude coordinates, email headers, and travel records like flight numbers. The system had compatibility issues, and NSA never added the additional information PROTON could handle. PROTON also appears to have the capacity for sophisticated data analysis: “PROTON tools find other entities that behave in a similar manner to a specific target.”
