“A new Mac Trojan has been discovered that creates a backdoor on an affected user’s machine. It was found on VirusTotal, sent by a user in Belarus. At the time of writing, the Command and Control (C&C) server is down and no longer sending commands to affected users. This appears to be a targeted attack, though the method of delivery is not yet known. So, while this has been affecting users in the wild, the overall threat level appears to be low.”
