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?

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?

That's right. But I didn't have any problem with transactions to\from the wallet - everithing was Ok

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

---

I have no idea. I did everything to prevent this from happening

Everybody says that. But the reality is - my PC is clean.  Online scanners confirm that as well. My static AV is Kaspersky right now.

No, I even don't know if it's

I couldn't remember anything like this in the last 3 years

I never did anything with my seed at all

thank you.
I've checked signatures for both of downloaded executables - they have identical result. No any errors found

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

Of course I do. I answered this question of yours on github already and can repeat the answer here -

since nobody paid attention to the above TXID - here is just statistics

6.57549844 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)

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?

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

2All - 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

And one more thing guys, it's about security issue - look at this, 3 days ago
https://github.com/spesmilo/electrum/issues/8244
Isn't it looks like something just begun?
I gonna ask there as well

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.

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 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.

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.

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.

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.

well I hasn'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.

Look.
The transaction is dated 03/15/2023. 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... 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. 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

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.

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?
