There are reports of another ledger hack which has more personal details leaked. This time the name, phone number, email and address are leaked.

I find it pretty crazy that they would store this stuff online to begin with. I suspect that since email, phone and addresses are leaked then most likely there is going to be lots of SMS sim swap hacks.

So if you are affected disable your SMS 2fa and use google Authenticator instead.

Hello,
I would like to know what would be the best option to store either eth or btc.
I have read all you said and I understand that an Air Gapped computer would be best but then how do you transfer funds if you need to? My guess is that you only connect it to the internet when you need to, right?  But I think this way the hacker can interfere exactly when you connect it and steal everything .  Maybe 2 networks would solve this problem? I do have 2 networks but from time to time I am forced to use the other one  therefore I dont have a network that it is not used 100%
I have seen that there is an airgap wallet made for tezos, btc,  eth etc. that uses 2 phones . 1 phone for cold storage with no conections (no sim and airplane mode activated probably or even shut down) and the other phone which is your daily phone . I think this would be a better choice because when you do a transaction you can use network from SIM which I suppose that it is more secure. I am not an expert so thats why I want to ask for your opinion but in my mind this seems to be a better way than computers because I know that phone are harder to hack (unless you have an app installed) and also because of SIM network.
Hardware wallets still have to connect to a computer and as we can see in this post they are not really safe... even with an airgapped computer you still need a network to dowload ledger live , update software etc.

In conclusion , am I right about 2 phones being more secure or would it be better to have a hardware wallet (ledger) connected to an airgapped computer? (What I didn't take in consideration is that the app itself could be malicious maybe... I don t know , thats why I ask Smiley) . Sorry if I sound dumb Cheesy )
If airgapped computer with ledger is the answer can you please tell me what a proper airgap setup would mean and how should I do it?
Thanks in advance!
All the best Smiley

EDIT: I seen that moccacino said that with a dedicated pc you dont even need a ledger. "get a dedicated pc for your wallet, just do a clean install, remove the network card (or deinstall the drivers), install the latest version of bitcoin core or electrum by following an airgapped setup walktrough and you'll have a wallet that tops a hw wallet when it comes to security. Just make sure you do it right... There are several ways you can mess up an airgapped setup... Ah, and make sure you keep a backup of your seed or wallet.dat on a couple usb sticks which you only plugin in your offline airgapped machine (and use a strong password to encrypt them"
Just a couple of questions here
1. How to install bitcoin core/electrum without network? Even if you take the file on usb from another computer from what I know a trojan/virus can migrate to that usb and the moment you insert it in your airgap pc its done (I could be very wrong)
2. How to make transactions if there is no connection to internet? (another ISP or is there a way to see if the network is safe? )
3  What it means to have a backup of seed? If I am writing the seed on a paper isn't that enough or going this way you cant recover the wallet with the seed?
4. Where is the password needed ? Folder password for wallet.dat or no ?

I hope you never used any "hacked" miner program from this site ... or from somewhere else .
This guys usually offering no miner fee ... free version of claymores or phonix or whatever miner program.
In 2018 , there was  a lot of trash new members here , who freshly registered , and the offered hacked miner programs.
I downloaded some to see what those "free" programs can do , what they offered, just to analyze them , and warn this community, if i see something not oks  ..
I made a mistake , i had a wallet program , Exoudus running in the background ....
 ... and basically those free miner programs opened a door to my computer.
Front of my eyes , my ETH wallet become empty , lucky me , i did not have that much ETH in my wallet .
You can file a complain here :
https://www.ic3.gov/Home/FileComplaint  ,
...but to be honest with you , you probably never going to see those stolen ETH's Sad

Why does that seem so far fetched?  You think its just ledger FUD to sell more Trezors?  Roll Eyes

Well someone smart enough to acquire 386 eth.  Would most likely not store all of it on 1 wallet.

ETH was extremely profitable to mine (in terms of ETH not USD or actual profit) back in late 2015. It had a good launch and then I think those that bought the ICO ended up dumping everything and at the end of the year I think ETH traded at less than $1.

An R9 280X didn't have any DAG issues with a low epoch, it actually mined at 27-28MH/s however it ate 200 Watts of power. So with $0.10 power, you were mining at a loss but generated 1 ETH per day per 280X.

Imagine mining ETH with a single 280X back in late 2015, to sell at $1400 in Jan 2018? Basically what Satoshi felt pretty much. However most like me either didn't mine at a loss or they mined and sold when ETH hit $10 or $20.

To mine at $1 a coin and sell at $1000 is extremely rare.

I had the same problem on 21 January 2019 I receive a replacement for my Ledger Nano S due the firmware upgrade, after the initial setup I move 1.9678 BTC to my Ledger than I have stored the key on safe place, a few weeks later I connect my Ledger in order to move some coins and I discovered than my balance was 0.
I checked the transaction and I find that on 29 January 2019 that someone has move all my BTC to this address:

36bbmZdw73MCN93qWE69X4pcJ3AS6dH3Rj

this is the TX ID: 8629187cb30f4e1facf5ba03f7426b19f2270aa4a48e299e10ff3b851d7de7ea

I never been able to have back my BTC

Probably your ledger nano was not genuine, hackers and scammers have been selling a modified version, beware.

I suspect someone that is working where ledger stores and ships their wallets is swapping out ledgers with tampered ones.

To mine at $1 a coin and sell at $1000 is extremely rare.

Imagine being part of the ethereum "team" and getting the majority of premined ethereum with very little work. Many of those team members did next to nothing and got huge bags of ethereum for it.

You don't need a hardware wallet, people were using paper wallet for years without any issues.

well one time i had the paper wallet folded in such a way that eventually a crease mangled some letters in a private key. it wasnt a trivial amount so i wasnt exactly happy that i had not thought about folds damaging letters when storing it.

took a while to sort it out. im more careful now.

i don't know and i forgot the numbers but i said this in 2015 heheh

Thanks for the info! I'm mining right now around 13 Mh/s. It's severely non-profitable. Which has me wondering why? Even more so, why are so many people hashing away and perfectly fine with losing money? Faith?

That depends on your power price and hardware.

lol youd be better off mining a coin with a lower diff with that hashrate....

Lower diff usually means lower price. Not that there aren't more profitable X11 coins to mine than DASH, currently. IMO, it's stupid to mine DASH in this case, even if you want DASH - instead, mine something else, sell it, buy DASH, and you end up with more DASH than you would have had, had you mined it directly.

Wolf0 is right mine other coin.......no more coins, better buy..it is all about buying the coins produced by the POS masternodes. POW is still there to make dash look more legit.

try ethereum it is more profitable, the coins move so fast dash's instantx is not that great anymore  Wink



anyway.. I think some people, start instamining and mining early and storing their stash for "cold storage" because of the success of BTC, a lot of people did it with many altcoins, the only problem is their "cold storage" became as cold as dead LOL, I think some got lucky with ETH  Cheesy
