For those people with Macs, there are dark clouds overhead. According to McAfee Labs, malware attacks designed for Mac computers rose 744 percent in 2016.
It started with the discovery of the Osx.Dok Trojan on Friday, 4/28/2017:
Yesterday, 5/2/2017, a new variant, Osx.Bella was uncovered.
Both of these Trojans are believed to have originated from Russia. This seems prudent as it is my own stereotypical (meaning “usual”, but not always) observation that Russians tend to infect business-related applications and documents while the PRC tends to infect games and animation. Needless to say, it is prudent to have Antivirus and Anti-malware installed and updated on your Mac. BitDefender is a good way to go, maybe even MalwareBytes.
The main delivery mechanism for this malware is by Email attachment. Check suspicious Emails by viewing the message headers. If you see any of the following messages on your display, you’ve got a Trojan at your doorstep. Note that in the case of the Apple Update, Apple calls it’s O/S “macOS”, not OS X. Don’t click any further. Power off the Mac, turn in back on, and then do an antivirus scan.
