Like any technology, WiFI has its own share of security concerns. The nature of wireless networks allows hackers or anyone with malicious intent to locate themselves close to an access point in order to infiltrate a network. According to Kasperksy, approximately 24.7% of Wi-Fi hotspots in the world do not use any encryption at all, and that does not even include the WiFi networks that are under-secured. More than 80 percent of U.S. companies have been successfully hacked, according to a Duke University/CFO Magazine Global Business Outlook Survey. Additionally, a survey by PricewaterhouseCoopers in early 2017 found that there has been a 38% increase in the instances of phishing scams and other cyber security incidents from 2015 to 2016.
