Topic: Stolen ETH from my Ledger - page 2. (Read 1491 times)

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.

LOL if only the people mining ETH in 2015 is able to see this quarell..you can mine it all in a day with a few 280x hehe

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

Also op has not posted again.

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

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 ) . Sorry if I sound dumb )
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

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 ?

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.

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

Yeah, sure. Btctalk rookie with 386 ETH. Keep going...

I wish the guy would reply so we can find out how his stuff got stolen. I reread and responses and he said that he never clicked on any links in emails and only did updates from the official ledger site.

So it would be nice to get more info and find out what exactly happened here. Maybe there is some security issue with the hardware wallet itself however I haven’t heard of anything really unless this case.

Other people got theirs stolen because they clicked the fake link and put in their seeds on a private website.

I sympathize with you.
I don't understand how you can steal cryptocurrency from a ledger.
If you have not interacted with your wallet with other smart contracts, then someone picked up or stole your passphrase.
A hacker attack will not help steal money from the ledger, because you confirm any operation by pressing buttons on the wallet.

The problem with network topic is you can't discuss it with newbs hehe

There are also layers of security for networks, for example know your MACs and IPs and block the rest, firewalls are only as good as you configure them.

I think it is easier for newbs and pros to just look at offline computers and hardware wallet..yes, even pros can miss something hehe

Also your network should not be shared in anyway, many people lose their funds and dont know why, I guess most of those cases are in shared networks, my point is if the hacker or program gets hold of your network then it can change the direction that transaction is going, reason i said a second not used network by any other devices is important.

Also, going forward, cyber attacks will occur more and more as prices of cryptocoins increase, people who live in metropolitan places are the ones that will most suffer from cyber attacks.

Yes the extreme bitcoin maximalists insist on buying some cheap $20 inkjet printer and destroying it afterwards Office Space style to prevent any cache or any faint proceeding print jobs to reveal part of the private key.

If you want an ETH cold storage you can print a paper wallet with MEW. Not sure if its still possible but a few years back that it what I did. However with ETH, I don't know if there is BIP38 encryption so you will need to find a way to excrypt that private key for extra protection in case someone gets a hold of your paper wallet.

THE  alt coins vary. Some do some don't .

If it is you home printer. Just print a long document it will flood the cache with new info

Destroy the printer??

Ok so this paper wallet site is apparently specific to bitcoin, is that correct? My current plan is to mine altcoins, most likely ETH, which I understand I have the option to convert to Bitcoin, but I haven't actually done anything yet.  Plan to get started early in the new year.  Would these same options exist for altcoins as well as bitcoin?

The metal seed savers look cool.  Like the president's nuke codes LOL. 

Basically you pay a fee whenever the coins are moved from address to address even if you are sending them to yourself. Best time to move coins is when there is no pending transactions and you can get away with a 1 sat/byte fee.

If you want to hodl for years then use a paper wallet like this,
https://www.bitaddress.org/

Save on USB stick, run on offline computer, make a wallet and use BIP38 encryption, print out 2-3 copies, destroy that printer afterwards, and put that in 2-3 different places. Like your house, your car, your bank. If someone sees it, they won't be able to do anything since its encrypted with BIP38.

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

there are hard metal seed savers.  let me find a link
