Piece of malware that uses multiple propagation and infection methods to drop a Monero cryptocurrency miner onto as many systems and servers as possible. Initially observed in China in early 2019, the methods it previously used to infect networks involved accessing weak passwords and using pass-the-hash technique, Windows admin tools, and brute force attacks with publicly available codes. However, this new case we found in Japan involves the use of the EternalBlue exploit and the abuse of PowerShell to break into the system and evade detection. It appears that the attackers are now expanding this botnet to other countries; TrendMicro telemetry has since detected this threat in Australia, Taiwan, Vietnam, Hong Kong, and India.
