New Update to the SIGINT Summaries

/ Christopher Parsons

Grondstation van de Nationale SIGINT Organisatie (NSO) in Burum, Frysl‚nI have added one new item to the SIGINT Summaries page. The Summaries include downloadable copies of leaked Communications Security Establishment (CSE) documents, along with summary, publication, and original source information.1 CSE is Canada’s foreign signals intelligence agency and has operated since the Second World War.

Documents were often produced by CSE’s closest partners which, collectively, form the ‘Five Eyes’ intelligence network. This network includes the CSE, the National Security Agency (NSA), the Government Communications Headquarters (GCHQ), Australian Signals Directorate (ASD),2 and Government Communications Security Bureau (GCSB)).

All of the documents are available for download from this website. Though I am hosting the documents they were all first published by another party. The new documents and their summaries are listed below. The full list of documents and their summary information is available on the Canadian SIGINT Summaries page.

The new contribution comes from documents released by CBC and covers how Five Eyes intelligence analysts correlated telephony and mobile Internet communications information. For the first time I have noted, in the summary block, all of the codenames that were mentioned in the redacted document.

Synergising Network Analysis Tradecraft: Network Tradecraft Advancement Team (NTAT)

Summary: This slide deck showcases some of the activities, and successes, of the Network Tradecraft Advancement Team (NTAT). The slides focus on how to develop and document tradecraft which is used to correlate telephony and Internet data. Two separate workshops are discussed, one in 2011 and another in 2012. Workshop outcomes included identifying potentially converged data (between telephony and Internet data) as well as geolocating mobile phone application servers. A common mobile gateway identification analytic was adopted by three agencies, including DSD. NTAT had also adopted the CRAFTY SHACK tradecraft documentation system over the courses of these workshops.

In an experiment, codenamed IRRITANT HORN, analysts explored whether they could identify connections between a potentially ‘revolutionary’ country and mobile applications servers. They successfully correlated connections with application servers which opened up the potential to conduct Man in the Middle attacks or effect operations towards the mobile devices, as well as the potential to harvest data in transit and at rest from the devices. In the profiling of mobile applications servers it appears that EONBLUE was used to collect information about a company named Poynt; that company’s application was being used by Blackberry users, and the servers profiled were located in Calgary, Alberta (Canada).

The agencies successfully found vulnerabilities in UCWeb, which was found to leak IMSI, MSISDN, IMEI, and other device characteristics. These vulnerabilities were used to discover a target and it was determined that the vulnerabilities might let a SIGINT agency serve malware to the target. A ‘microplugin’ for XKeyscore was developed so that analysts could quickly surface UCWeb-related SIGINT material. (NOTE: The Citizen Lab analyzed later versions of UCWeb and found vulnerabilities that were subsequently patched by the company.

CSIS’s New Powers Demand New Accountability Mechanisms

/ Christopher Parsons

6165458242_97e0572d03_oThe Government of Canada recently tabled Bill C-44, the Protection of Canada from Terrorists Act, in response to a series of court defeats concerning how the Canadian Intelligence and Security Service (CSIS) collects intelligence about Canadian residents. The federal courts took CSIS to task after Justice Richard Mosley realized that warrants issued to CSIS, which enabled CSIS to collaborate with Canada’s foreign signal intelligence agency to monitor Canadians abroad, were also being used to enlist the assistance of other nations’ signals intelligence agencies. In addition to the warrants not being issued with such foreign collaboration in mind there was — and remains — a judicial belief that CSIS’ lawyers deliberately misled the court when requesting the warrants.

The tabled legislation would not alleviate the ruling that CSIS lawyers misled the court. It would, however, authorize CSIS to apply for warrants which authorize the service to monitor Canadians abroad even if doing so would violate the laws of foreign nations. Moreover, CSIS would be empowered to request the assistance of foreign organizations in monitoring the aforementioned Canadians. The Act would also provide the government the power to prevent courts from publicly examining informants as well as to revoke citizenship under certain situations. Finally, the legislation further clarifies (and arguably extends) prohibitions on revealing the identity of CSIS officers. Continue reading →

The Danger of Fetishizing BlackBerry Messenger Security

/ Christopher Parsons / 5 Comments

BlackBerry Bold 9780Research in Motion has a problem. For years they promoted themselves as a top-notch mobile security company. During those initial years most of their products were pitched at enterprise users.

Then RIM got into the consumer market.

Most consumers equate RIM’s products with security, email, BlackBerry Messenger (BBM), and a tepid suite of other smartphone features. Most of the people who report on the company tend to agonize over the fact that RIM complies with government surveillance laws. Such reports inevitably emerge each time that the public realizes that RIM meets its lawful access requirements for consumer-line products.

In this post, I want to briefly address some of the BBM-related security concerns and try to (again) correct the record surrounding the security promises of the messaging service. After outlining the deficits of consumer BBM products I briefly argue that we need to avoid fetishizing technology, encryption, or the law, and should instead focus on the democratic implications of the lawful access-style laws that governments use to access citizens’ communications.

In the interest of full disclose: I have family and friends who work at Research In Motion. I haven’t spoken to any of them concerning this post or its contents. None directly work on either BBM or RIM’s encryption systems.
