As reported by 9News, a cybersecurity expert at VPNPro, Jan Youngren mentioned that using a free VPN could actually leave users vulnerable to hacking than not using one at all. He also mentioned that users are more willing to transmit sensitive information on VPN apps than on other apps. He also added that "For a VPN app to then be so vulnerable is a betrayal of users' trust and puts them in a worse position than if they hadn't used any VPN at all."

In addition, he said the hackers could be "Browsing a fake, malicious website set up by the hacker and aided by these dangerous VPN apps. While everything will appear to work normally, and you think that you're being extra safe and secure, you're actually being seriously exposed."
