Several more variants of Ragtime appear in recently leaked documents. A leaked document shines new light on a surveillance program developed by the National Security Agency. The program, known as Ragtime, collects the contents of communications, such as emails and text messages, of foreign nationals under the authority of several US surveillance laws. Details of the program are held in the highest tiers of secrecy, known as exceptionally controlled information, with only a few NSA staffers having access to the program and its data. There were four known versions, according to a 2013 book, released just months before the first documents published from the cache of documents leaked by whistleblower Edward Snowden. Ragtime-A is said to involve the US-based collection of foreign-to-foreign counterterrorism data; Ragtime-B collects foreign government data that travels through the US; and Ragtime-C focuses on the nuclear counterproliferation effort. Another program stands for Ragtime-P, which is said to stand for the Patriot Act, which authorizes the collection of bulk metadata on calls and emails sent over the networks of telecom providers. A leaked court order showed Verizon was ordered to turn over customer call records to the NSA on a daily basis. Dozens of other companies have also been compelled to provide data for Ragtime. But the Ragtime program has many more versions -- including one that appears to involve Americans' data. The document was found buried in a virtual hard disk, discovered by UpGuard's Chris Vickery. The document seen by ZDNet, dated November 2011, shows the Ragtime program has eleven variants, including the four that were already known. The document alludes to Ragtime-BQ, F, N, PQ, S, and T. The eleventh version refers to Ragtime-USP. "USP" is a common term used across the intelligence community to refer to "US person," like a US citizen or lawful permanent resident. Image: ZDNet Americans are generally protected from government surveillance under the Fourth Amendment. A few exceptions exist, such as if the secretive Washington DC-based Foreign Intelligence Surveillance Court, which authorizes the government's spying activities, issues a warrant based on probable cause, such as if there is evidence of an American working for a foreign power. But the NSA has long "incidentally" collected data on Americans, reports and research have revealed. Ragtime dates back to 2002, according to a previously-leaked document. The program forms part of a wider collection of systems and databases under the STELLARWIND umbrella of warrantless surveillance programs, launched under the authority of then-president George W. Bush in response to the September 11, 2001 terrorist attacks. After a series of leaks in 2008 detailing the scope and breadth of STELLARWIND's domestic collection capability, Congress limited the government's surveillance powers. Changes to the law had an immediate impact on the Ragtime program. Although the government was barred from collecting new metadata on Americans under Ragtime-P, the NSA retained the data. Analysts with clearance were still permitted to search the database. Only a fraction of NSA staffers have the appropriate security clearance to access Ragtime's databases. One previously leaked document says analysts must have special "need to know" clearance to access the data, and any information relating to Ragtime is restricted from being shared to foreign intelligence partners. The exception is Ragtime-C, which the new document implies a level of co-operation from the UK government. The data stored in Ragtime's databases is so sensitive that their very existence is compartmentalized. The clearance level for each Ragtime version, according to the document, is "unpublished," in an effort to ensure that the programs themselves aren't widely known about across the agency. The NSA said in internal security guidance that unpublished classification markings are set for some programs "due to sensitivity and restrictive access controls." When reached, an NSA spokesperson declined to comment on Ragtime, or its purpose. News of the leak comes just weeks before Congress has to pass reforms or a reauthorization of the US government's surveillance laws. Lawmakers have until the end of the year to pass a bill to ensure powers under the Foreign Intelligence Surveillance Act are put back in the law books, or the NSA risks losing those powers at the end of the annual intelligence cycle. These are the same powers that authorized the controversial PRISM program, which collects data from servers of internet giants, the massive bulk collection of internet traffic, and the government's computer and network hacking powers. Several bills have already been floated by members of both the House and Senate. US intelligence chiefs are pushing for a permanent reauthorization of the surveillance powers, while privacy groups are fighting for greater transparency. Several members of Congress have vowed to fight the reauthorization until they learn how many Americans are swept up in section 702 surveillance. The government's spy chief has so far refused to say what that number is. Via http://www.zdnet.com/article/ragtime-program-appear-in-nsa-leaked-files/
