DNS changing Malware affects Mac users

OSX/MaMi hijacks macOSís DNS settings to intercept traffic by routing it through malicious servers...But unless you did something to bypass macOSís Gatekeeper security, you likely have nothing to worry about since the malwareís executable isnít signed by Apple.

Patrick [Wardle] believes that the attackers could be using lame methods like malicious emails, web-based fake security alerts/popups, or social-engineering type attacks to target Mac users.
Open System Prefs->Network. Click "Advanced" and then the "DNS" tab. Look for:
If you find those IP addresses, you have been infected by the malware. Currently no fix, but you can at least delete those two addresses.

Dear X-Air and WeatherCat sys-admins,

Thanks for the head's up.  Indeed most of us are safe from this malware, and sure enough, I double-checked our home network and all is safe and sound.

Cheers, Edouard
