Hello all, After having so many discussions about Privacy here in this board the past week, (specially TryNinja and o_e_l_e_o and some others) I decided to become a protonmail paid user. It was hard to find, but it is live: https://protonmail.com/blackfriday5% discount.50% discount The two year plan is about 0.009 Bitcoin (sadly, there is no discount for bitcoin payment method so far. Requested on reddit, let's see if they say anything, if anyone wanna comment there to help me, you are welcome). That's pretty reasonable, with 5GB drive. There are two big problems for me, but I can live with them: -Missing Calendar -Missing a Driver app (could be web), like outbox or google drive. Does anyone know a solution/turn around for those problems? Yeah, proton has those offers all the time. Does anyone really know who is behind proton, its not a honey pot? |

Because either way if it's a weak passphrase you're going to loose your BTC. Not necessarily. For hardware wallets, the attacker still needs to extract the seed. On Trezor devices we now know that can be done for less than $100 with fairly basic components. As far as we know, other devices still require high tech equipment and the expertise to use it. Very few people have the access and skills required, and hiring such a lab would cost several thousand dollars at a minimum. It's simply not a concern for your average crypto user, but is a concern for people holding large sums of money who are being specifically targeted by criminals. Sorry to be a downer, but it just gets to me that this is out there and yet they are still selling them and people think they are safe just using an 8 digit pin. Nothing is 100% safe, and if you have access to additional options (such as passphrases) which increase your security, then I would always opt to use them. Well, it would be quite unique to have a multi-sig with one trezor, one ledger and letsay a bitcoin core wallet, then a two word phrase is enough as long as the attacker does not know which one is which. There are even cooler methods but should not be disclosed as of yet... |

Yes, you can hack a trezor and extract all 24 words Do you care to elaborate on that maybe? Where did you read or hear about Trezor wallets getting hacked and seed words being extracted? I did read an article a while ago published by Kaspersky it is possible to gain access to the seed using a hacking technique called voltage glitching. More about that here: Source: https://www.kaspersky.com/blog/hardware-wallets-hacked/25315/Using a hacking technique called voltage glitching (applying lowered voltage to a microcontroller, which causes funny effects in the chip) they switched Trezor One’s chip state from “no access” to “partial access,” which allowed them to read the chip’s RAM, but not the flash storage. After that they found out that when the firmware upgrade process is started, the chip places the cryptographic seed into RAM to retain it while the flash is being overwritten. In this manner, they managed to get all memory contents. Finding the cryptographic seed in this dump turned out to be no problem; it was stored in RAM unencrypted, in the form of a mnemonic phrase (meaning actual words instead of random number) that was easy to spot.  You can hack a Trezor using side channel attack, there are various tools for this, one is Chipwhisperer manufactured in Canada. Their CEO even demonstrated the hack in a video in Las Vegas in August this year. |

You'll find a lot of articles and threads with google.
For as much security as possible, you need 1 thing:
An completely airgapped computer. Not connected to any network, no wifi/bluetooth, etc..
How exactly you store your private keys, is up to you.
You could use a core wallet.dat file, electrum, a hardware wallet which you only connect to that computer, an encrypted text file with private keys, multisig spread across multiple airgapped computers, etc...
Doesnt matter if the computer is airgapped if the passphrase is weak |

Can hardware wallets like Ledger Nano be hacked and their coins stolen?
Yes, you can hack a trezor and extract all 24 words |
