Our investigation of a spearphishing campaign that targeted senior members of the World Uyghur Congress in March 2025 reveals a highly-customized attack delivery method.

Meryem and her family left the Xinjiang region in China for Turkey in the early 1990s, before settling in North America. As a human rights defender, Meryem has experienced various digital threats in response to her activism. She is frequently attacked by what she believes to be Chinese state-backed trolls on X, Facebook, and in the comment section on public Zoom meetings.
Since 2014, the Chinese government has escalated its repression against Uyghurs and other Turkic ethnic minorities in the Xinjiang region in northwestern China.

China’s efforts extend also across borders as its authorities engage in a widespread campaign of transnational repression that targets individuals both on the basis of their ethnic identity and their activities.
