electrum wallet problem

[nc50lc]

TQ for all reply my msg -snip- i think is electrum wallet have bug,dunno hacker how to use the bug to hack my wallet

If it's a bug in Electrum, every user should have been hacked the same way as you.
The problem here is you never tried what's suggested like verifying electrum or providing screenshot, just jumping to conclusions.

But since it's really unrecoverable and finding the cause doesn't seem to concern you, we can wrap this thread up.
Most of your info doesn't add up anyways.

This screenshot doesn't prove anything. A fraudulent Electrum binary looks very likely completely identical to the original Electrum.
You would need to check your downloaded binary if it has been properly signed with the developer's PGP keys.

To check if your downloaded Electrum binary is genuine, ie. signed by the developers ThomasV and maybe also SomberNight and Emzy (not sure if all three signed the v4.0.9 of Electrum) is the very basic but mandatory step every Electrum user should do.

But even if your Electrum binary is genuine, there are many more ways to loose funds from a hot wallet.

It seems you don't understand anything from the previous posts are you living in China? use translate.google.com to understand what other people posts above.

I think you didn't understand about verifying Electrum to make sure you are using a legit Electrum wallet. You can read this guide below on how to do it

- https://bitcointalk.org/index.php?topic=5240594.0

You must read that thread first to understand how it works use the translator if you didn't understand then go back here for the result.

And the website they are talking about is starting with https not the screenshot of your Electrum wallet. The official website of Electrum is Electrum.org and if you downloaded the Electrum wallet on different source or website then it's a malware or fake Electrum wallet.

Yes, that's the one.
So it seems like it's an "[imported wallet]" and not "[imported watching-only]", which you have the key.
Together with the other screenshot that you've PM'ed me, the transactions matched with the address from your deleted reply.
Now, we can rule out one of the possible cause that's mentioned by others.

2015 i create wallet from multibit ，

electrum wallet i download from electrum webside version 4.0.9

Judging from the dates and the screenshot's Electrum version, v4.0.9 (2020-Dec-18 ~ 2021-Mar-30) matched the latest version at that time.
If it's a fake version, the funds would've been stolen a few moments after you unlocked the wallet, but it happened months later.
It's highly unlikely that it's a fake Electrum (but it's much better if you can verify electrum's signature).

The other possibilities that I can think of are:

• [1] Since it's never opened while it's hacked, the hacker must had access to your private key. Example, from your backup or from [2].
• [2] Your MultiBit wallet may be accessed by the hacker. Since you just imported the private key to Electrum, the fund is still accessible using the key in your MultiBit.
  Note that deleted files can still be restored unless the disk was zero filled or physically destroyed.

The hacker might got access to your MultiBit only in June 2021.
The thing is, the funds were sent while Electrum is offline for a long time, the most probable way for the hacker to steal your bitcoins that way is to get access to the address' private key then import it to his own wallet to spend it himself, so it's either one of the two options.

The delay may be caused by some hindrance which no one knows, it depends on how you dispose of MultiBit and its backups after you imported the prvKey to Electrum.
MultiBit doesn't have to work, he just have to get the wallet file to export the private key from it.

Note: The bitcoins wasn't actually moved to Electrum, importing the private key doesn't mean that it's sent to that imported Electrum wallet;
Importing the prvKey just granted your Electrum access to the funds, but it's still accessible using the original wallet.

In my opinion the OP doesn't have a fraudulent Electrum binary but rather his former MultiBit private key(s) have been somehow stolen by the hacker.

I didn't pay enough attention to the "[imported]" in the screenshot of the OP's Electrum wallet window title which indicates an Electrum wallet where the private key(s) have been imported. So it's very likely not a security issue of Electrum (that many more users would've likely experienced) but rather a security issue of the underlying private key(s) of the user's former MultiBit wallet.

The OP could have likely saved his stolen Bitcoins by sweeping the old private key(s) into a newly created standard Electrum wallet (a new HD wallet with completely new private keys) and not only importing private key(s) into a non-HD Electrum wallet.

You owned something that was worth a certain amount of your local currency and was stolen from your possession. In the majority of jurisdictions this should be enough for the police to file a case, it shouldn't matter if they're not the brightest candles on the cake to know or recognize what Bitcoin is. Of course, you may live in a country that has ignorant police. Involving a lawyer to push a theft case will cost you money and chances are very likely pretty slim to pinpoint the thief and get your Bitcoins back.

Unfortunately that's bad for those who lost their coins by theft and even worse the thieves get away with their crimes.

What happened with the computer that you originally installed the Multibit client on in 2015?
Is it the same computer that you use now?
Did you give it to someone, did you sell it?
What do you use your computers for where you keep you wallets and private keys? Any torrents, pirated games, porn?
How tech savvy are you? Do you believe you could have caught some type of malware due to your internet activities?

The keys were imported from Multibit and maybe a second computer. That means the same keys exist and were hot in two different software wallets and possibly two different computers.
