SmallTiger

SmallTiger is malware used by North Korean state-sponsored actors, specifically APT45 (Andariel). The provided content states that APT45 employed SmallTiger against South Korean defense, semiconductor, and automotive manufacturing entities, and more broadly places this activity within North Korean targeting of the defense industrial base. The malware is referenced alongside other North Korean backdoors, including THINWAVE, in campaigns characterized by social engineering, infrastructure mimicry, and AI-driven reconnaissance. High-confidence context indicates North Korean operations targeted defense-related organizations in South Korea and also broader aerospace, defense, energy, and semiconductor sectors in the United States and Europe. No specific infection chain, technical capabilities, persistence mechanisms, command-and-control details, or indicators of compromise for SmallTiger are provided in the content beyond its use as malware/backdoor by APT45 (Andariel).
