I am a Senior Research Fellow at Citizen Lab, a co-founder of Bahrain Watch, and a Postdoctoral Researcher at UC Berkeley, where I received my PhD in Computer Science under the advisorship of Vern Paxson. My work focuses on novel technological threats to Internet freedom, including new censorship and surveillance tools. My expertise is in Internet scanning and conducting digital investigations. Coverage of my work has been featured in Vanity Fair, the New York Times, the Washington Post, on CNN, and on Larry King.
In this note, we describe a security issue where users in the “Waiting Room” of a Zoom meeting could have spied on the meeting, even if they were not approved to join. Zoom fixed the issue after we reported it to them.
This report examines the encryption that protects meetings in the popular Zoom teleconference app. We find that Zoom has “rolled their own” encryption scheme, which has significant weaknesses. In addition, we identify potential areas of concern in Zoom’s infrastructure, including observing the transmission of meeting encryption keys to China.
New York Times journalist Ben Hubbard was targeted with NSO Group’s Pegasus spyware via a June 2018 SMS message promising details about “Ben Hubbard and the story of the Saudi Royal Family.” The SMS contained a hyperlink to a website used by a Pegasus operator that we call KINGDOM. We have linked KINGDOM to Saudi Arabia. In 2018, KINGDOM also targeted Saudi dissidents including Omar Abdulaziz, Ghanem al-Masarir, and Yahya Assiri, as well as a staff member at Amnesty International.
This campaign is the first documented case of one-click mobile exploits used to target Tibetan groups, and reflects an escalation in the sophistication of digital espionage threats targeting the community.
This research brief details how Griselda Triana, journalist and the wife of slain journalist Javier Valdez Cárdenas, was targeted with NSO Group’s Pegasus spyware in the days after his killing.
Two days after the murder of award-winning Mexican journalist Javier Valdez Cárdenas, two of his colleagues began receiving text messages laden with NSO Group’s Pegasus spyware. To date, 24 targets of Pegasus have been identified in Mexico. This case additionally illustrates an alarming trend of spyware attacks around the world specifically aimed at journalists.
In this report, we describe how Canadian permanent resident and Saudi dissident Omar Abdulaziz was targeted with a fake package delivery notification. We assess with high confidence that Abdulaziz’s phone was infected with NSO’s Pegasus spyware. We attribute this infection to a Pegasus operator linked to Saudi Arabia.
في هذا التقرير ، نَصِف كيف تم استهداف المقيم الدائم في كندا، والمنشق السعودي؛ “عمر عبد العزيز”، عبر إشعار مزيف عن “تتبع شحنة بريد”. نحن وجدنا -وبثقة عالية- أن هاتف عبد العزيز قد تم استهدافه ببرنامج التجسس “بيغاسوس” من شركة NSO. نعزو هذه الإصابة إلى مشغل “بيغاسوس” مرتبط بالمملكة العربية السعودية.
عَمِلنا في هذا البحث على تطوير تقنيات جديدة لمسح الإنترنت لتحديد 45 بلداً قد يقوم فيها مشغلو برامج التجسس بيغاسوس من شركة NSO بإجراء عمليات تجسس.
In this post, we develop new Internet scanning techniques to identify 45 countries in which operators of NSO Group’s Pegasus spyware may be conducting operations.
