A China-based APT has been sending organizations spear-phishing emails that distribute a never-before-seen intelligence-collecting RAT dubbed Sepulcher. The RAT has been distributed in various campaigns over the past six months, targeting both European officials and Tibetan dissidents. Researchers tied the campaigns to APT group TA413, which they say has been associated with Chinese state interests and is known for targeting the Tibetan community. They said the campaign is reminiscent of a July 2019 campaign that was used to distribute ExileRAT; the TA413 group has also been documented in association with this RAT.
