With no clear\r\nconnection to any previous attack group, we gave this new threat actor the name “Earth\r\nWendigo.”\r\nAdditional investigation shows that the threat actor also sent spear-phishing emails embedded\r\nwith malicious links to multiple individuals, including politicians and activists, who support\r\nmovements in Tibet, the Uyghur region, or Hong Kong. However, this is a separate series of\r\nattacks from their operation in Taiwan, which this report covers.\r\nObserved\r\nSectors: Education, Government and politicians and activists, who support movements in\r\nTibet, the Uyghur region, or Hong Kong.\r\nCountries: Taiwan.\r\nTools used Cobalt Strike.\r\nInformation\r\n\u003chttps://www.trendmicro.com/en_us/research/21/a/earth-wendigo-injects-javascript-backdoor-to-service-worker-for-.html\u003e\r\nLast change to this card: 07 January 2021\r\nDownload this actor card in PDF or JSON format\r\nSource: https://apt.etda.or.th/cgi-bin/showcard.cgi?u=94bb4827-bba0-4b88-a6de-c7db9e6e8c1d\r\nhttps://apt.etda.or.th/cgi-bin/showcard.cgi?u=94bb4827-bba0-4b88-a6de-c7db9e6e8c1d\r\nPage 1 of 1",
