According to Google, a group of free VPNs and proxy services were part of a larger network used by 550+ hacking groups to obscure their internet traffic. The IPIDEA proxy network offered customers access to over 60 million IP addresses, letting buyers access the web as local users from various parts of the globe. Google’s investigation found that several free VPN and proxy brands were feeding into IPIDEA, including DoorVPN, Galleon VPN, Radish VPN, and Aman VPN. This also means that hackers who used IPIDEA could access users' private devices on the same network. IPIDEA users are also from China, as well as Russia, North Korea, and Iran.
