Second time this year, MyEtherWallet that offers services to manage cryptocurrencies suffered a severe security issue. While the good news is that MyEtherWallet regular users were not impacted because the problem was not with the wallet services, but with the VPN services Hola to connect to MyEtherwallet. While the VPN services were compromised for five hours, it suggests people use a paid service rather than using a free VPN. How many users were hit and what is the impact is still unclear?
