One mark of infection is the presence of two new components in /Library: /Library/LaunchAgents/ is the visible property list file, and /Library/.rand/updateragent.app is hidden. These include persistent components which open a back door, and can steal information about macOS, browser history and login information, some cryptocurrency wallets, 1Password data, and more. They contain two new versions of Proton, dubbed OSX/Proton.C and OSX/Proton.D, which do not appear to be detected yet by Apple’s built-in malware protection XProtect. Infected versions of Elmedia Player were discovered on 19 October 2017 in downloads from Eltima. If you have downloaded a copy of Eltima’s Elmedia Player from Eltima’s website in the last few days, you should check your Mac as a matter of urgency: there’s a chance that it brought with it a copy of Proton malware, according to a report just posted by ESET.
