Miner Malware Spreads Beyond China, Uses Multiple Propagation Methods Including EternalBlue, Powershell Abuse | Cell Phone Spy and Mobile Tracking Software
By Augusto Remillano II and Arvin Macaraeg We detected a 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; our telemetry has since detected this threat in Australia, Taiwan, Vietnam, Hong Kong, and India. Propagation and Behavior The malware's (detected by Trend Micro as Trojan.PS1.LUDICROUZ.A) primary propagation technique involves trying a list of weak credentials to log into other computers connected to the network.
