Summary

Hide ▲

A Konni APT operation is using spear-phishing and KakaoTalk to compromise Android users in South Korea, enabling device compromise and malware spread. The multi-stage tradecraft matters because it combines trusted messaging accounts, social engineering, and follow-on propagation to widen impact across a Korean user cohort. The activity began in July of last year and was still being used through Sept. 15.
