Finding You: The Network Effect of Telecommunications Vulnerabilities for Location Disclosure

Last week, I published a report with Gary Miller and the Citizen Lab entitled, “Finding You: The Network Effect of Telecommunications Vulnerabilities for Location Disclosure.” I undertook this research while still employed by the Citizen Lab and was delighted to see it available to the public. In it, we discuss how the configuration and vulnerabilities of contemporary telecommunications networks enables surveillance actors to surreptitiously monitor the location of mobile phone users.

The report provides a high-level overview of the geolocation-related threats associated with contemporary networks that depend on the protocols used by 3G, 4G, and 5G network operators, followed by evidence of the proliferation of these threats. Part 1 provides the historical context of unauthorized location disclosures in mobile networks and the importance of the target identifiers used by surveillance actors. Part 2 explains how mobile networks are made vulnerable by signaling protocols used for international roaming, and how networks are made available to surveillance actors to carry out attacks. An overview of the mobile ecosystem lays the foundation for the technical details of domestic versus international network surveillance, while the vectors of active versus passive surveillance techniques with evidence of attacks shows how location information is presented to the actor. Part 3 provides details of a case study from a media report that shows evidence of widespread state-sponsored surveillance, followed by threat intelligence data revealing network sources attributed to attacks detected in 2023. These case studies underscore the significance and relevance of undertaking these kinds of surveillance operations.

Deficiencies in oversight and accountability of network security are discussed in Part 4. This includes outlining the incentives and enablers that are provided to surveillance actors from industry organizations and government regulatory agencies. Part 5 makes clear that the adoption of 5G technologies will not mitigate future surveillance risks unless policymakers quickly move to compel telecommunications providers to adopt the security features that are available in 5G standards and equipment. If policymakers do not move swiftly then surveillance actors may continue to prey upon mobile phone users by tracking their physical location. Such a future paints a bleak picture of user privacy and must be avoided.

Public and Privacy Policy Implications of PHAC’s Use of Mobility Information

Last week I appeared before the House of Commons’ Standing Committee on Access to Information, Privacy, and Ethics to testify about the public and private policy implications of PHAC’s use of mobility information since March 2020. I provided oral comments to the committee which were, substantially, a truncated version of the brief I submitted. If interested, my oral comments are available to download. What follows in this post is the content of the brief which was submitted.

Introduction

  1. I am a senior research associate at the Citizen Lab, Munk School of Global Affairs & Public Policy at the University of Toronto. My research explores the intersection of law, policy, and technology, and focuses on issues of national security, data security, and data privacy. While I submit these comments in a professional capacity they do not necessarily represent the full views of the Citizen Lab.

Canadian Government’s Pandemic Data Collection Reveals Serious Privacy, Transparency, and Accountability Deficits

Just before Christmas, Swikar Oli published an article in the National Post that discussed how the Public Health Agency of Canada (PHAC) obtained aggregated and anonymized mobility data for 33 million Canadians. From the story, we learn that the contract was awarded in March to TELUS, and that PHAC used the mobility data to “understand possible links between movement of populations within Canada and spread of COVID-19.”

Around the same time as the article was published, PHAC posted a notice of tender to continue collecting aggregated and anonymized mobility data that is associated with Canadian cellular devices. The contract would remain in place for several years and be used to continue providing mobility-related intelligence to PHAC.

Separate from either of these means of collecting data, PHAC has been also purchasing mobility data “… from companies who specialize in producing anonymized and aggregated mobility data based on location-based services that are embedded into various third-party apps on personal devices.” There has, also, been little discussion of PHAC’s collection and use of data from these kinds of third-parties, which tend to be advertising and data surveillance companies that consumers have no idea are collecting, repackaging, and monetizing their personal information.

There are, at first glance, at least four major issues that arise out of how PHAC has obtained and can use the aggregated and anonymized information to which they have had, and plan to have, access.

Huawei & 5G: Clarifying the Canadian Equities and Charting a Strategic Path Forward

I’ve published a report with the Citizen Lab, entitled, “Huawei and 5: Clarifying the Canadian Equities and Charting a Strategic Path Forward.” The report first provides a background to 5G and the Chinese telecommunications vendor, Huawei, as well as the activities that have been undertaken by Canada’s closest allies before delving into issues that have been raised about Huawei, its products, and its links to the Chinese government. At its core, the report argues that Canada doesn’t have a ‘Huawei problem’ per se, so much as a desperate need to develop a principled and integrated set of industrial, cybersecurity, and foreign policy strategies. The report concludes by providing a range of suggestions for some elements of such strategies, along the lines of how Canada might develop and protect its intellectual property, better manage trade issues, and develop stronger cybersecurity postures.

A Predator in Your Pocket : A Multidisciplinary Assessment of the Stalkerware Application Industry

With a series of incredible co-authors at the Citizen Lab, I’ve co-authored a report that extensively investigates the stalkerware ecosystem. Stalkerware refers to spyware which is either deliberately manufactured to, or repurposed to, facilitate intimate partner violence, abuse, or harassment. “A Predator in Your Pocket” is accompanied by a companion legal report, also released by the Citizen Lab. This companion report is entitled “Installing Fear: A Canadian Legal and Policy Analysis of Using, Developing, and Selling Smartphone Spyware and Stalkerware Applications,” and conducts a comprehensive criminal, civil, regulatory, and international law assessment of the legality of developing, selling, and using stalkerware.

The (In)effectiveness of Voluntarily Produced Transparency Reports

Payphones by Christopher Parsons (All Rights Reserved)

I have a paper on telecommunications transparency reports which has been accepted for publication in Business and Society for later this year.

Centrally, the paper finds that companies will not necessarily produce easily comparable reports in relatively calm political waters and that, even should reports become comparable, they may conceal as much as they reveal. Using a model for evaluating transparency reporting used by Fung, Graham, and Weil in their 2007 book, Full Disclosure: The Perils and Promises of Transparency, I find that the reports issued by telecommunications companies are somewhat effective because they have led to changes in corporate behaviour and stakeholder interest, but have have been largely ineffective in prodding governments to behave more accountably. Moreover, reports issued by Canadian companies routinely omit how companies themselves are involved in facilitating government surveillance efforts when not legally required to do so. In effect, transparency reporting — even if comparable across industry partners — risks treating the symptom — the secrecy of surveillance — without getting to the cause — how surveillance is facilitated by firms themselves.

A pre-copyedited version of the paper, titled, “The (In)effectiveness of Voluntarily Produced Transparency Reports,” is available at the Social Sciences Research Network.
