Trojan.Win64.CoinMiner.ca

CoinMiner is a type of malware that harnesses the victim's computer resources, primarily CPU and RAM, to engage in cryptocurrency mining, such as for Monero or Zcash. This malware establishes persistence by integrating an open-source mining tool into the system's startup routine without the user's consent. Advanced coin miners often employ techniques like timer configurations or CPU usage limits to operate discreetly and avoid detection.
