Espionage Tactics Against Tibetans
A Citizen Lab research study of Chinese attack and espionage tactics against Tibetan networks and users.
This report describes the latest iteration in a long-running espionage campaign against the Tibetan community. We detail how the attackers continuously adapt their campaigns to their targets, shifting tactics from document-based malware to conventional phishing that draws on "inside" knowledge of community activities. This adaptation appears to track changes in security behaviors within the Tibetan community, which has been promoting a move from sharing attachments via e-mail to using cloud-based file sharing alternatives such as Google Drive.
We connect the attack group's infrastructure and techniques to a group previously identified by Palo Alto Networks, which they named Scarlet Mimic. We provide further context on Scarlet Mimic's targeting and tactics, and the intended victims of their attack campaigns. In addition, while Scarlet Mimic may be conducting malware attacks using other infrastructure, we analyze how the attackers re-purposed a cluster of their malware Command and Control (C2) infrastructure to mount the recent phishing campaign.
This move is only the latest development in the ongoing cat and mouse game between attack groups like Scarlet Mimic and the Tibetan community. The speed and ease with which attackers continue to adapt highlights the challenges faced by Tibetans who are trying to remain safe online.
