Canadian Spies Collect Domestic Emails in Secret Security Sweep - The Intercept - 0 views

  • Canada’s electronic surveillance agency is covertly monitoring vast amounts of Canadians’ emails as part of a sweeping domestic cybersecurity operation, according to top-secret documents. The surveillance initiative, revealed Wednesday by CBC News in collaboration with The Intercept, is sifting through millions of emails sent to Canadian government agencies and departments, archiving details about them on a database for months or even years. The data mining operation is carried out by the Communications Security Establishment, or CSE, Canada’s equivalent of the National Security Agency. Its existence is disclosed in documents obtained by The Intercept from NSA whistleblower Edward Snowden. The emails are vacuumed up by the Canadian agency as part of its mandate to defend against hacking attacks and malware targeting government computers. It relies on a system codenamed PONY EXPRESS to analyze the messages in a bid to detect potential cyber threats.
  • Last year, CSE acknowledged it collected some private communications as part of cybersecurity efforts. But it refused to divulge the number of communications being stored or to explain for how long any intercepted messages would be retained. Now, the Snowden documents shine a light for the first time on the huge scope of the operation — exposing the controversial details the government withheld from the public. Under Canada’s criminal code, CSE is not allowed to eavesdrop on Canadians’ communications. But the agency can be granted special ministerial exemptions if its efforts are linked to protecting government infrastructure — a loophole that the Snowden documents show is being used to monitor the emails. The latest revelations will trigger concerns about how Canadians’ private correspondence with government employees are being archived by the spy agency and potentially shared with police or allied surveillance agencies overseas, such as the NSA. Members of the public routinely communicate with government employees when, for instance, filing tax returns, writing a letter to a member of parliament, applying for employment insurance benefits or submitting a passport application.
  • Chris Parsons, an internet security expert with the Toronto-based internet think tank Citizen Lab, told CBC News that “you should be able to communicate with your government without the fear that what you say … could come back to haunt you in unexpected ways.” Parsons said that there are legitimate cybersecurity purposes for the agency to keep tabs on communications with the government, but he added: “When we collect huge volumes, it’s not just used to track bad guys. It goes into data stores for years or months at a time and then it can be used at any point in the future.” In a top-secret CSE document on the security operation, dated from 2010, the agency says it “processes 400,000 emails per day” and admits that it is suffering from “information overload” because it is scooping up “too much data.” The document outlines how CSE built a system to handle a massive 400 terabytes of data from Internet networks each month — including Canadians’ emails — as part of the cyber operation. (A single terabyte of data can hold about a billion pages of text, or about 250,000 average-sized mp3 files.)

  • The agency notes in the document that it is storing large amounts of “passively tapped network traffic” for “days to months,” encompassing the contents of emails, attachments and other online activity. It adds that it stores some kinds of metadata — data showing who has contacted whom and when, but not the content of the message — for “months to years.” The document says that CSE has “excellent access to full take data” as part of its cyber operations and is receiving policy support on “use of intercepted private communications.” The term “full take” is surveillance-agency jargon that refers to the bulk collection of both content and metadata from Internet traffic. Another top-secret document on the surveillance dated from 2010 suggests the agency may be obtaining at least some of the data by covertly mining it directly from Canadian Internet cables. CSE notes in the document that it is “processing emails off the wire.”

Canada Casts Global Surveillance Dragnet Over File Downloads - The Intercept - 0 views

  • Canada’s leading surveillance agency is monitoring millions of Internet users’ file downloads in a dragnet search to identify extremists, according to top-secret documents. The covert operation, revealed Wednesday by CBC News in collaboration with The Intercept, taps into Internet cables and analyzes records of up to 15 million downloads daily from popular websites commonly used to share videos, photographs, music, and other files. The revelations about the spying initiative, codenamed LEVITATION, are the first from the trove of files provided by National Security Agency whistleblower Edward Snowden to show that the Canadian government has launched its own globe-spanning Internet mass surveillance system. According to the documents, the LEVITATION program can monitor downloads in several countries across Europe, the Middle East, North Africa, and North America. It is led by the Communications Security Establishment, or CSE, Canada’s equivalent of the NSA. (The Canadian agency was formerly known as “CSEC” until a recent name change.)
  • The latest disclosure sheds light on Canada’s broad existing surveillance capabilities at a time when the country’s government is pushing for a further expansion of security powers following attacks in Ottawa and Quebec last year. Ron Deibert, director of University of Toronto-based Internet security think tank Citizen Lab, said LEVITATION illustrates the “giant X-ray machine over all our digital lives.” “Every single thing that you do – in this case uploading/downloading files to these sites – that act is being archived, collected and analyzed,” Deibert said, after reviewing documents about the online spying operation for CBC News. David Christopher, a spokesman for Vancouver-based open Internet advocacy group OpenMedia.ca, said the surveillance showed “robust action” was needed to rein in the Canadian agency’s operations.
  • In a top-secret PowerPoint presentation, dated from mid-2012, an analyst from the agency jokes about how, while hunting for extremists, the LEVITATION system gets clogged with information on innocuous downloads of the musical TV series Glee. CSE finds some 350 “interesting” downloads each month, the presentation notes, a number that amounts to less than 0.0001 per cent of the total collected data. The agency stores details about downloads and uploads to and from 102 different popular file-sharing websites, according to the 2012 document, which describes the collected records as “free file upload,” or FFU, “events.” Only three of the websites are named: RapidShare, SendSpace, and the now defunct MegaUpload.

  • “The specific uses that they talk about in this [counter-terrorism] context may not be the problem, but it’s what else they can do,” said Tamir Israel, a lawyer with the University of Ottawa’s Canadian Internet Policy and Public Interest Clinic. Picking which downloads to monitor is essentially “completely at the discretion of CSE,” Israel added. The file-sharing surveillance also raises questions about the number of Canadians whose downloading habits could have been swept up as part of LEVITATION’s dragnet. By law, CSE isn’t allowed to target Canadians. In the LEVITATION presentation, however, two Canadian IP addresses that trace back to a web server in Montreal appear on a list of suspicious downloads found across the world. The same list includes downloads that CSE monitored in closely allied countries, including the United Kingdom, United States, Spain, Brazil, Germany and Portugal. It is unclear from the document whether LEVITATION has ever prevented any terrorist attacks. The agency cites only two successes of the program in the 2012 presentation: the discovery of a hostage video through a previously unknown target, and an uploaded document that contained the hostage strategy of a terrorist organization. The hostage in the discovered video was ultimately killed, according to public reports.
  • LEVITATION does not rely on cooperation from any of the file-sharing companies. A separate secret CSE operation codenamed ATOMIC BANJO obtains the data directly from internet cables that it has tapped into, and the agency then sifts out the unique IP address of each computer that downloaded files from the targeted websites. The IP addresses are valuable pieces of information to CSE’s analysts, helping to identify people whose downloads have been flagged as suspicious. The analysts use the IP addresses as a kind of search term, entering them into other surveillance databases that they have access to, such as the vast repositories of intercepted Internet data shared with the Canadian agency by the NSA and its British counterpart Government Communications Headquarters. If successful, the searches will return a list of results showing other websites visited by the people downloading the files – in some cases revealing associations with Facebook or Google accounts. In turn, these accounts may reveal the names and the locations of individual downloaders, opening the door for further surveillance of their activities.
