Microsoft is warning of malware, Dexphot, that has infected more than 80,000 machines, sucking up their CPU power in order to mine cryptocurrency. Researchers first discovered Dexphot in October 2018 and saw its activity peak during July. They said that the malware has a complex attack chain and also uses various methods to outwit detection efforts, including an obfuscated script designed to check for antivirus products, and regularly-scheduled malware updates.
