I was amazed by this news, I thought that hardware wallets are top secure for saving our bitcoins, Indeed, I thought to buy one in the future, but after reading this PDF. I will keep my bitcoin in some web wallets as I don't have too much, in the same time, I will search for the secure wallet from now on.
Web wallets are much worse. Just use Bitcoin Core, or other similar software. Web wallets have many more attack vectors than local software.
