MAC users take note, there's evil malware in the wild - and - according to Checkpoint's Ofer Caspi of the highly competent Checkpoint Malware Research Team, the bits in question are not just pernicous, but tenacious as well, and, interestingly, specifically targeting Mac users. Dubbed OSX/Dok it's time to update your virus prophylaxis on your MAC, forthwith.

The OSX/Dok malware is distributed via a phishing campaign, which is usually not a new or surprising attack vector, however this time it targets specifically macOS users, who are mostly perceived as malware-proof. This phishing campaign is combined with a MiTM attack, allowing complete access to all victim communication, even if it’s SSL encrypted. - via Checkpoint's Ofer Caspi - Checkpoint Malware Research Team
