For years we've all depended on the WPA2 (Wi-Fi Protected Access) protocol to secure our Wi-Fi networks.
Security researcher Mathy Vanhoef has revealed what he has labeled KRACK, an exploit that attacks a vulnerability in the handshake of the WPA2 protocol that you most likely use to protect your Wi-Fi at home and millions of small businesses around the world use, too.
This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker sends specially crafted messages to a Microsoft Server Message Block 1.0 (SMBv1) server.

The days of malware being just a problem for Windows users are long gone, with malicious software now appearing for all major operating systems. The latest, and most dangerous to hit the Mac yet, is called OSX/Dok. It targets any and all versions of Mac OS X and will take complete control of your Mac if you let it.
First the good news: in order for Dok to infect a Mac the user needs to open a .zip archive attached to an email. Most people's suspicions will be raised as soon as they see the Dokument.zip archive attached to an email they don't recognize. Those that don't are in for some pain.
According to Check Point, Dok is not currently detected on VirusTotal, meaning it won't get picked up by any security software run on your system (this will likely change quickly). Dok also uses a developer ceritificate that is signed and therefore authenticated by Apple, meaning your Mac will allow it to install and Gatekeeper is on no help.
