APT41 (aka Winnti, Amoeba) is a notorious Chinese APT group. In recent years, TeamT5 CTI team observes that the group has developed into multiple subgroups and it has posed a serious threat to companies in the APAC region. In this talk, we will cover an emerging Chinese APT group named "Tianwu," which was first spotted in 2020. We found that there are several TTPs overlap between Tianwu and APT41. Tianwu's proprietary tool, Pangolin8RAT, is a modular trojan that supports at least 8 communication protocols. Our talk will also provide our outlook on the group's future development as well as actionable intelligence for enterprises.
