The OP doesn't seem interested in evaluating his own habits and practices to make sure this never happens again. Doing so would equate to taking responsibility and accountability for the loss, while it's much easier to blame the software or the developers. I can't say that the OP is unique in this situation, the lack of accountability seems to be a societal plague these days.
Absolutely not. My first thought was - "where and when did I mess up." I convulsively recalled whether I went where, downloaded what, what incidents happened during this time, how long ago I changed the password, etc. That is why your conclusion about the removal of responsibility is a miss. And I tried to answer all your questions as detailed as possible. That's why there were fewer questions asked - the wrong picture comes out. Especially in the context of the number of affected people. And - yes, that's right, I'm upset that the money is lost - they have been accumulating for more than one year there, for a minute. And it is precisely on the basis of an analysis of the general situation that I conclude that something more than just my mistake happened and that this software was unable to protect me. As I wrote above you can work with the wallet profile from another PC by simply entering the correct password. I wanted to clarify - does everyone know that this same file contains your seed phrase as well? Even if you write it on your forehead and put the cap on your very nose, but if this file falls into the wrong hands, the phrase will also be in these hands and the wallet can be restored as many times as the thief wants, no matter how you change the password of the remaining copies of you? PS: by the way who was that genius who put the game as a captcha? I hardly understood at all what was needed from me and how to achieve this. You would have forced to solve the Newton binomial  |

Your earlier post states you were virus checking the electrum file rather than using the signatures electrum provides for this purpose. I suspect that's why you lost the Bitcoin or because you did not use a hardware wallet or sign the transaction on a air gapped computer.
I posted both answers - about antivirus Ok and about GPG Ok. And - yes I don't have a cold wallet otherwice I wouldn't write this topic, right?
Maybe the hacker is very close to you. Does anyone have access to your computer? Do you have a weak login password? Do you have a login password at all? These things happen too. Maybe a friend of yours took a photo of your priv key with his cell phone while you were taking a piss and then he decided to rob you after a few days.
I have to duplicate my answer - none but the cat. To use a password the wallet-file need to be stolen but it wasn't as I already said. Please be careful - many of the questions have already been asked and answered. |

A few years ago there were some malicious Electrum servers broadcasting a message to Electrum users directing them to download and install a malware version of Electrum. The malware wallet would send all the bitcoin in the wallet to the hacker's address whenever the user made an attempt to send ay transaction. I don't know if seed phrases were compromised by the same hack, but that certainly could have happened.
That's right. But I didn't have any problem with transactions to\from the wallet - everithing was Ok I would suggest you start from scratch; fresh OS install, fresh Electrum install and make sure to verify the download before installing it, and then create a new seed. Write the seed down on paper, and store it in a safe place. Don't store the seed digitally, and don't store on any cloud servers. It's clear. I gonna create a new wallet. But I won't can change settings of some stations which send BTC to this wallet's adress because no access to them right now. I'm unable to make sure if someone else has access to my wallet, am I right? As I already noted I've checked my exe's with GPG
In most cases concerning the theft of bitcoins, it's the user who made one or multiple mistakes. The problem is, people don't want to admit making mistakes, not to themselves and not to others. It's always something else that caused it.
Everything you do on that computer can potentially be a landmine because that's what happens if the device that holds your keys is constantly online and used for various other activities. You need to separate that. Getting a hardware wallet is the easiest way. Getting a second laptop with a genuine OS that you aren't going to use for other things online is another way. Using a completely airgapped solution is the least user-friendly but safest option.
You are right. But your advice is a bit late - I just lost all the coins. And given the fact that they have been mined for many years, it doesn’t matter anymore, I’m unlikely to be able to get into the same situation in the near future.
The money was saved for the education of my kids or for the purchase of housing. Now it doesn't matter anymore. I am sure that even if it is confirmed that the attack was successful not due to user error, but using some kind of wallet vulnerability, Electrum does not compensate for the losses to its users, as Nicehash did in a similar situation. Because it is always easier to write off such things as viruses, errors, licenses and other rubbish than to admit there is a problem and take responsibility for the result. |

What about some other wallet software? The fellow on Github who's funds were also stolen mentioned he had installed a wallet on different machine, I'm assuming he means some software other than Electrum. Have you used some other software to access your Electrum wallet, possibly?
No, I even don't know if it's It's rather odd, because the other guy was using the Android software, and you indicated you're using Windows Desktop software. The issue gives me the impression that a hacker gained access to your private keys or seed phrase, but to have done so on two separate platforms (operating systems) is rather unlikely.
I encourage you to think back to any risky behavior you may have engaged in that could have led to your being phished.
I couldn't remember anything like this in the last 3 years
But how then your wallet has been hacked ?
I have no idea. I did everything to prevent this from happeningWhich antivirus you use in your computer. I think you downloaded serious virus/malware somewhere.
Everybody says that. But the reality is - my PC is clean. Online scanners confirm that as well. My static AV is Kaspersky right now.
Tell us a bit more about the computer where you used Electrum and which holds your achieved seed phrase.
What do you use it for? It makes no sense not telling the truth because it's an unfortunate learning experience. You are not going to get your BTC back, but you can learn what you did wrong and not repeat it again.
Do you use a genuine and licensed OS or a pirated one?
Do you use other pirated and cracked software on it?
Do you have other wallets installed on the same computer for any cryptocurrencies?
Is the .rar password easy to guess or bruteforce? Did you use the same password somewhere else?
Do you play cracked PC games, download torrents, watch porn, browse any other forums, software or hacking related?
Who else uses or has access to your computer?
Have you received any emails recently that you have clicked on or opened?
Are you active on Telegram or other social media and in what capacity?
What did you do in the days prior to your coins getting hacked? Did you visit any new sites, installed new software, talked with new people, anything out of the ordinary?
I'm not a gamer at all, my only game is HMM 3.5 which was downloaded 15 years ago. About a year ago I had to leave my hometown because of the war UA - RU. I'm the only user of my laptop and no one else can access it in the apartment - there's no one but the cat who doesn't like BTC at all. During this time, nothing strange or dangerous happened to the software. The license is irrelevant to the situation as it doesn't require cracks or anything like that. So I really don't have any options how it could be other than if the seed was stolen much earlier, more than a year or three years. But judging by what happened, one gets the impression not of long-term storage and use years after the theft, but that the penetration took place in a recent period, which is impossible in my case. |

Base on that transaction that you posted, and the other guy on Github who's funds were swept in the same transaction, I can only assume that your seed was compromised. Did you sign up for any give-away or stake in some air-drop, or something of the sort? Did you divulge your seed to any entity that promised you a reward of some type?
I never did anything with my seed at all |
|
|

thank you. I checked the signatures for both downloaded executables - they have an identical result. No errors found By the way, Antivirus can't be a good indicator since even real Electrum, specially the older versions usually have false-positive detection from some Antivitus software.
I know. Just one more additional check |

since nobody paid attention to the above TXID - here is just statistics
Jeez, I think you used fake electrum. Just if Electrum's link has faking exe's. I can upload previously used standalone - it wasn't deleted. And it was checked by an antivirus without any warnings as well as all other files on my laptop
No, that's not entirely true. If you're using your Electrum wallet, by default your profile is stored in the Windows users Roaming directory and you can clean it up with a clean reinstall of Windows. But you can definitely restore it with a seed. My problem is completely different. Please read my answers carefully from the beginning.
Before I answer, I have read your post twice so I took the quote of the question @bitmover which asks where do you save the seed phrase? which I think is a good question to find a solution to the problem you are facing friend. Thank you for you try but I would like to ask you again to pay attention for my posts - I already answered that question the seed file is always located in another archive, also under a password. I never turn to him - there is no need. It has not been available on PC for many years.

2 DireWolfM14 That definitely looks like a scammer's transaction. Multiple types of addresses indicates that the private keys with UTXOs were swept all at once, and with a fee of 50 sats/vByte. Only a scammer would apply such an expensive fee, to make sure that no one can replace the transaction with a higher fee. Do you remember where you downloaded the software from? Of course I do. I answered this question of yours on github already and can repeat the answer here - dowloaded from a link at the status bar of the standalone of course, every time if it had an update there >> 2 BTCGalaxyA12 Hello.
Today, when logging into the wallet, I received a message about an outgoing transaction dated 12/03/2023. As a result, my balance was reset to zero. What should I do? Can I do anything to return the money?
(Program version 4.3.3 at the time of entry)
This is the same question I asked in a self-made topic where I asked when we reinstall our laptop, will the assets stored in Electrum be deleted? Almost all of the answers I got were automatically the same, that is, deleted, except that when reinstalling the laptop, the seed pharse is still stored, allowing it to be re-entered. No, that's not entirely true. If you're using your Electrum wallet, by default your profile is stored in the Windows users Roaming directory and you can clean it up with a clean reinstall of Windows. But you can definitely restore it with a seed. My problem is completely different. Please read my answers carefully from the beginning. |

well I haven't tried this anywhere else but - yes, that's that I did myself to access my wallet on my laptop. I'll try it on another PC and send you the result.
Not necessary, but if you wanna do, then pls with the "temp-wallet" profile. Just wondering if you've ever accessed your wallet on another device(not yours) without making sure if it's safe from being infected with malware or you simply trust the owner. Thank you for your worry but at fist my wallet is empty now as you know and second - i have several servers which i can use safe 2 All - the story has some new facts - there is another user with the same problem. Check my question at issues page amd new repplies there https://github.com/spesmilo/electrum/issues/8263
2 rat03gopoh as I expected, it works. I just copied the Electrum profile folder and pointed the standalone-version to it. And after entering the password, I got access without any questions. On a completely different PC with a different address. Hell, that's an elephant-sized security hole! If you steal a profile, you can easy bruteforce a password, and this is clearly easier than bruteforce a seed phrase! Who there said that deleting a profile from a PC and storing it in an archive under an additional password is a waste of time - wants to repeat this phrase again?  >> since nobody paid attention to the above TXID - here is just statistics https://www.blockchain.com/explorer/transactions/btc/ccd6dbffcdf801821906d21e426f9f170b49fa0fb97edcbe01e538c32651788e6.57549844 BTC was dropped on the hacker's address in total. I'm proud of myself - I'm in the top five cool losers. There are only two dudes cooler than me with 0.5BTC and one with 0.7BTC. They .ucked everyone they could hook - there is an address from which they took as much as 0.0.000019 BTC - this dude is definitely laughing, because this amount would not even be enough for him to withdraw interest) [moderator's note: consecutive posts merged] |

You didn't answer my question in the beginning. In the first post.
Where did you store your seed?
All you said about archive program and password means nothing and this doesn't increase your security.
With the seed anyone can just download electrum and move your coins. The seed should be your main concern.
The seed phrase should always be written in paper, which is unhackable.
It is very likely that your computer is compromised and the hacker just got access to your seed. This may have happened in the time you just created the wallet and saw the seed for the first time or later on.
the seed file is always located in another archive, also under a password. I never turn to him - there is no need. It has not been available on PC for many years.
There was no text file with the phrase. And I haven't logged into Electrum since January. None of this is stored in decrypted form anywhere else. Knowing only the password, assuming it is impossible to access the wallet. So another option suggests itself - the vulnerability of Electrum itself, the specified version. It was this executable file that was last executed in January. And it was taken from the link from the previous version, also from the official location.
Can you clarify these a bit? Do you mean is that when you created the wallet it didn't give you a text/seed phrase? No. Of course, when creating the wallet, the seed phrase was generated and I have it. But, as I already answered above to another participant, I do not contact her - to access the wallet, it is enough to indicate the folder with the wallet to the program and enter the correct password. There is a vulnerability on Electrum before but it was fixed on 3.3.4 lower versions are still prawns to phishing you might have an older version than 3.3.4 and recently updated it to the latest version. Since you said that you downloaded the latest version by using the link from the previous version which is possible a phishing site.
And did you just install it without verifying the installer with the GPG tool?
I don't have any issue using the latest version but if you believe that it's a vulnerability you are free to report it directly on their GitHub page and then bring some proof that there is a leak.
I know about the vulnerability in 3.3.3. I can’t say which version I started working with this wallet with, but the exe file was always downloaded from the official website using the link from the status bar of the program. In the first message, I indicated that the last access was using version 4.3.3, which officially has no vulnerabilities at the moment.
It is a pity that this will not help me or the users of the wallet in any way - it means that there will still be the same leaks from the wallets of other owners.
You still don't seem to understand. Electrum happens to be one of the most widely used desktop wallets, along with Bitcoin Core, and has a vast user base of millions of individuals worldwide who utilize it at any given moment. It's highly unlikely that any security vulnerabilities within the software would go unnoticed, given the sheer volume of users and the attention that such flaws would attract online. I'm not saying it's impossible, just very unlikely. So, rather than making baseless accusations, it would be more constructive to provide evidence to support your claims. I guess users of version 3.3.3 have also been told, right? I chose exactly for its prevalence and reviews in a very distant year. I haven't had any problems since before this incident. About 3rd party... I mean somebody did this without hacking my PC. I don't know how it could be done and it's looks imposible for me too.
Electrum is open-source software. Feel free to review the code yourself and report any loopholes or vulnerabilities you find. I doubt very much that my level of knowledge of languages will allow me to understand the code. Have you been able or just decided to show sarcasm? ) But above I wrote why I think that access to my PC at the time of the specified date would not have given anything even if it had happened
After reading your explanation, I must say that I have serious concerns regarding your OPSEC and its effectiveness. Deleting your wallet profile after each use provide no significant protection, as it offers no real advantage in terms of security, unless you used an offline, air-gapped device to sign your transactions. Similarly, there is little advantage to adding another password to the archive since the wallet file's encryption already provides an adequate level of protection and is virtually impossible to break. But it certainly won't get any worse, right? When an object is present but encrypted, that's one thing. But when an object is missing, it doesn't matter if it's encrypted, it just doesn't exist. |

The scheme of work is as follows: I use the standalone version of the client. The Electrum profile itself does not exist on the computer - it is in the archive under a password. If I need to make a transaction, I unpack the profile folder to a specific location, indicate this location to the program, enter the password and get access. At the end, I close the program, again I archive the profile folder with its removal from the location.
Please tutor me about your security method by extracting the electrum profile file elsewhere (tbh this is the first time I've heard of this method). So, anyone who has the profile folder and (somehow) has the encryption password to the folder and the access password to electrum will be able to open your electrum profile and do anything including sweeping your balance, right? Does it also work if accessing the profile using another device with a copy of that profile file and have you tried it? well I haven't tried this anywhere else but - yes, that's that I did myself to access my wallet on my laptop. I'll try it on another PC and send you the result. |

There is no tech support for Electrum this section is the right place to seek help with Electrum. Or if you have some issues or bugs you can report them from their GitHub check the link below - https://github.com/spesmilo/electrum/issuesBut you can not report your issue there because you were hacked or have a compromised wallet. What I guess is that you are being phished or your PC is compromised would you mind telling us what 3rd party you mention above? Look. The transaction is dated 03/12/2023. At this point, there was no Electrum profile on the PC. And there was no text file with the phrase. And I haven't logged into Electrum since January. None of this is stored in decrypted form anywhere else. Knowing only the password, assuming it is impossible to access the wallet. So another option suggests itself - the vulnerability of Electrum itself, the specified version. It was this executable file that was last executed in January. And it was taken from the link from the previous version, also from the official location. It is a pity that this will not help me or the users of the wallet in any way - it means that there will still be the same leaks from the wallets of other owners. About 3rd party...

thanks everyone for the replies.
Perhaps the translation was not very accurate - my English is far from ideal and I have to use Google.
The scheme of work is as follows: I use the standalone version of the client. The Electrum profile itself does not exist on the computer - it is in the archive under a password. If I need to make a transaction, I unpack the profile folder to a specific location, indicate this location to the program, enter the password and get access. At the end, I close the program, again I archive the profile folder with its removal from the location.
Those. Initially, there is no folder with a wallet or a file with a phrase on the PC. Therefore, I cannot understand how exactly without this phrase and in the absence of access to the wallet file, access to transactions could be obtained.
And - yes, I imagine how the blockchain works. Please don't waste your time visualizing how much smarter you are. Thank you.

What should I do? Discover what is compromised in your system. Format your computer. Buy a hardware wallet.Where did you stored your seed? In a paper? If not, that is a mistake. Can I do anything to return the money?
No. The wallet profile was missing on the PC, as well as the passphrase to restore it. I don't think it's my PC. I believe that the actions were carried out on a third-party resource. Does Electrum have tech support to check this? How can I communicate them? |

Hi.
I've phoenix miner running under hiveOS. The question is: why does his monitoring console have no color? Is there any command line parameters for this or it's by design?
|

Most mining software has dropped support for very old cards where it just isnt reasonable to expect miners to use. Ethminer is opensource and supports just about all cards. There just arent very many Titan 6gb these days.
that's right. But strange thing - phoenix 5.5c can mine GT770 (cuda 3.0) with no error at 2-3MH. My Titan is corupted? Games going ok.. did you try claymore miner? it always had good support of older amd generations. Also you may need to install some very old driver that may not even be not supported in recent winX builds ... yes I did. Showing error "wrong data from pool". |

Have a stupid question but ask - GTX Titan 6Gb can mine anything at the moment?
<CUT>Well the card was made in 2013 and is barely faster than a GTX970 so its not going to be a great miner. Power usage is probably very high as well. An R9 390 is actually faster than this card.
miner29, Thank you 4 support. There was one moment with ethminer - in some period it change reported hashrate from 0.8-1MH to 16.5MH, so... looks like it can mine eth, but ethminer have no parameter to set algo and as result it mine something wrong from pool. Anyway it's offtop and other questions are to ethminer dev. Last question: why ethminer can and phoenix can't? May be I just not found right parameters for subj? |
