A Trojan pretending to be a cryptocurrency ticker called CoinTicker is installing backdoors on Macs of unsuspecting users. The application is secretly downloading two backdoors onto the infected mac that allows an attacker to take remote control of the computer. The Trojan will download customized versions of the EggShell and EvilOSX backdoors from a Github repository that has since been taken offline. It is not known if the Coin Ticker app was designed purely for malicious purposes or has been compromised by attackers.
