Citizen Lab’s latest research publications.
In this report we track a malware operation targeting members of the Tibetan Parliament that used known and patched exploits to deliver a custom backdoor known as KeyBoy. We analyze multiple versions of KeyBoy revealing a development cycle focused on avoiding basic antivirus detection.
Citizen Lab Senior Research Fellow John Scott-Railton has published an updated version of his “Security for the High-Risk user” paper, first published in the IEEE Security & Privacy in spring 2016. The updates were made based on new evidence of attacks against two-factor and account recovery SMSes, underlining the need for innovation in two-factor authentication.
In this report, we reverse engineer three popular live streaming platforms (YY, Sina Show, and 9158) and find keyword lists used to censor chat messages. Tracking changes to the keyword lists over the past year gives an inside look into how these applications implement censorship
Canada’s National Security Consultation: Digital Anonymity & Subscriber Identification Revisited… Yet Again

This report, written by Research Associate Christopher Parsons and CIPPIC Staff lawyer Tamir Israel, investigates the surveillance capabilities of IMSI Catchers, efforts by states to prevent information relating to IMSI Catchers from entering the public record, and the legal and policy frameworks that govern the use of these devices. The report principally focuses on Canadian agencies but, to do so, draws comparative examples from other jurisdictions. The report concludes with a series of recommended transparency and control mechanisms that are designed to properly contain the use of the devices and temper their more intrusive features.
This report describes how a government targeted an internationally recognized human rights defender, Ahmed Mansoor, with the Trident, a chain of zero-day exploits designed to infect his iPhone with sophisticated commercial spyware.
