No. No. Did I mention... no. Nothing is unhackable. As evidence...In January 2018, Cisco Systems (a very highly respected maker of internet communications hardware) revealed that a critical bug was found in its ASA (Adaptive Security Appliance) software that could allow hackers to execute code remotely.This is a bug in enterprise-level VPN systems used by corporations, so it's severe, indeed. Fortunately, responsible IT administrators can patch their systems to fix the bug. However, it goes to show how no system can be truly deemed absolutely secure.Another example was a bug in Hotspot Shield, a popular VPN service. This bug allowed a hacker to expose private information, including originating IP. Hotspot Shield issued an update, which gives us an excuse to remind you that you should always install updates, especially on your VPN client software.
