1. Ransomware Holding Files HostageA fangled and very nasty new type of malware reared its head in 2016: Ransomware. Ransomware kidnaps files through encryption, holds them hostage and then demands payment before releasing them. Many variants of Ransomware made the news in 2016, the scariest one an amateurish version called Ranscam that deletes files whether you pay or not. Ransomware became so popular as a method of exploitation that it affected as much as half of all businesses in the US.
In case you were wondering what happened with Yahoo, in September the company revealed that its users were severely compromised when over 500 million accounts were hacked. To make matters worse, it was later disclosed that the hack actually happened in 2014 - which means that hackers had access to sensitive user information for years. As if this is not enough, in December it was revealed that more than a billion users were already hacked in August 2013.

QuickTime was once one of the most pervasive pieces of software on PCs as it was crucial for watching videos in early days. Today of course, the situation has changed, and there are several video options to choose from, which is a good thing. Why? Because after two serious vulnerabilities were uncovered in the QuickTime software early in 2016, Apple decided that fixing these issues was too much of a mission and rather decided to condemn QuickTime for Windows. In other words, if you're using QuickTime for Windows on your PC, it might be a good idea to look for additional video viewing options.

Believe it or not, these four major breaches were not the only serious security breaches in 2016. Even the NSA was hacked this past year. Internet security safety is rapidly becoming a very serious global issue with a veritable army of 'smart' devices linked together in the ‘cloud’, we are becoming more and more vulnerable. Let's hope that active cyber defense evolves as quickly.
