Hi. I first noticed this when I tried to copy my bitcoin address, and put it Blockchair. The address is not the one that should have been copied!

It is not clear that they have been hacked. This your problem might be that of malware your device got caught. It is a malware mostly on the keyboard which changes your bitcoin address copied to the scammers address most of these addresses are similar to the original one with mostly the first few characters and the last ones looking same. You can read about this attack here and on how to fix it  https://bitcointalk.org/index.php?topic=5190776.0 (https://bitcointalk.org/index.php?topic=5190776.0)

Have you seen any official announcement from block chair about this?
Is this reproducible in other devices also?

Because if not, it could be also that it's a local issue.

Malware will often try to infect your clipboard in order make you send funds to an attacker's address. So it could also be a local issue.

Sounds like there might be something fishy going on with your device instead of the blockchair being hacked.  Could be some kinda clipboard malware messing things up.  I'd say run one of those antivirus and anti-malware scans or something, just to make sure there's no malicious software on your device and  might help figure out what's causing this. Have you tried copy-pasting your btc address somewhere other than the blockchair website?

I just test the https://blockchair.com site, and everything is working perfectly. If you tried to copy your Bitcoin address and discovered that a wrong address was displayed after you copied the correct address, then your device might be under attack. It could be a clipboard virus or other malware.

Either you are a person who is meticulous and pay attention to small details or you were just lucky. The easiest ways to prevent this from happening again is to install an antivirus on your device. Aside the antivirus software, the best thing you can do for yourself is to after you have copied the address write the last letters or alphabets manually. Also try to uninstall each piece of software piece by piece and then test whether it is better or worse that is if you noticed that it came after you installed a piece of software. This is not the only way as there are many. Hopefully one works best for you.

Blockchair looks fine to me. You probably have clipboard hijacker malware in your PC that change crypto-currency addresses to different ones and try to steal your coins. This is a method of theft that we see frequently last years. Clean your PC before making any transactions. It's lucky you realized this in advance.

It is not blockchair that's been hack, there's no news and the site works perfectly. It is you that has been compromised by that copy-paste malware or virusand you probably have downloaded it somewhere else.

If you can remember on which apps or files you have downloaded and will be able to share, everyone can have an idea that file or app contains the malware so all can avoid downloading it.

You can check it on your download history.

I tried going to blockchair and there didn't seem to be any problems nor did I see them announcing that their site had been hacked. Have you made sure that you copied the address correctly and when you redo it, does this still happen to you?

I agree with other members' comments, that there may be something wrong with the device you are using. You need to check your device for any malicious software on it.

There isn't issues with blockchair website it's something you're saying you've seen. You didn't take print screen of the browser so we don't know what you've seen. If you've copied addresses but it's changed after you've pasted it means you've been attacked by hijacking virus. Blockchair isn't hacked.

Before you claim something to be hacked, you need to first confirm how the thing works. Since you copied your address and pasted it in there and noticed the changes, have you tried using another method like copying and pasting the address on another website or even on a notepad to see if the address will still be the same or if it will change? If it doesn't, that's when you should know where your problem is from.
 
But for the time being, the chance of your PC or whatever gadget you are using being hacked is much higher than the chance of your blockchair being hacked. You should be thankful that it's not in sending out transactions that you notice this, like most people usually notice this.
 
Try wiping out your gadget even if it will take you to get a new operating system in order for you to be sure that the virus is being wiped out of the system, or better yet, you should still be typing the address on your keyboard instead of copying and pasting it.

This may be the first case of clipboard hijacking case I have actually seen someone realizing about the issue before losing any money. Good on you OP, your attention to your address and your attention to detail has provably saved you from scammers.
I would recommend you to do some backup or your important information (ideally you should do it in a cloud service which also have scanning for viruses and unwanted software), after you have got all your important stuff backed, then wipe completely your devices and your USD drives, to be sure something like this will ever happen to you in the whort term.
You probably got this virus by participating in fishy and shady places related to cryptocurrencies or airdrops. Be careful what you link on, good luck does not last forever.  ::)

I do not expect that this is due to the site being hacked, but most likely your computer has a clipboard hijack virus. This virus detects addresses that are copied to the clipboard and replaces them with addresses belonging to the hacker.

My laptop was exposed to this virus a while ago and some of my coins were stolen, but I was finally able to get rid of it and clean the device. You have to scan your device with an anti-virus program and clean it completely.

Blockchair works fine, I copy and paste addresses there back and forth without any issues, so maybe it's not hacked because Blockchair looks fine, but as others have said the clipboard virus attacks your device, you should still be careful before pasting and make sure the address is really yours.

If your device has been attacked by other malware viruses then this is more dangerous and it could be that the coins stored in the hotwallet on your device can be hacked, so try to check again before there is further loss.

It is malware issue on your device. You have to wipe out that device or use a new device but let's spend your time to check your online habit that seems to be bad and unsafe enough to make your device infected with malwares.

Blockchair.com itself is only a block explorer and you don't lose your bitcoin by copy and paste your public Bitcoin address on Blockchair.com explorer or any block explorer.

i think the problem is not with the blockchair but with the device you are using, maybe it is infected with a virus or malware which makes you paste something you shouldn't. have you scanned the device you are using? you should do a thorough scan of the device you are using because it may be infected with a virus.

This is the likely culprit OP because if it's on their side, they would've issued some sort of statement already about this incident. It's commendable that you're able to do double checking, definitely saved yourself from a hacker that wanted to steal from you. It's scary that this kind of stuff is happening, imagine those that are spending their bitcoin to buy stuff for the holidays but they got scammed, definitely heartbreaking and difficult to understand how people are doing this, not fighting fair.

It's not even make sense the hacker want to change your address since they can't access your wallet if you not share your seed phrase.

They can hack blockchair, but they aims to get the data or other information, that's.

The best way to get rid off from viruses is factory reset, although that means you're also delete everything in your device.

It is possible that something has happened to you and not to the blockchair.
Maybe your clipboard function is not working properly because the blockchair site still has transactions as usual and today ^{at least when my fingers are typing} I also monitor transaction activity on blockchair which also looks as usual.

As mentioned, maybe your device has been infiltrated by malware so the clipboard function is not working properly.

Be careful when copying, especially copying seed phrases or private keys on the clipboard using a mobile device.

The soon you reinstall/update the operating system the more your PC will be secured. Your Keyboard has been successfully hacked and I fear that rest of software including browser and wallet could also be compromise soon if you don't take action on time.

This issue only happens with you asbit is ok from myside. you could check on other explore too and you will see the same result.

If Don't know keyboard hack scam Read this (https://www.pcrisk.com/removal-guides/24043-cryptowallet-address-replacing-virus) where more than thousand malicious program used for keyboard hacking purpose. Don't download any program from unofficial website.

They don't need their seed phrase. What they do is basically install some malware and when it detects that some BTC address is in the clipboard it replaces it with the thief's BTC address and they are hoping that you don't notice while sending the transaction. Unless you are sending this to an address you send frequently, most of the time you don't look at the address that you paste, hence why this malware works out for the hackers.

Basically you need to format your computer and install everything from scratch.

In fact they don't have a user panel, if they get hacked I don't think there's anything to worry about.
On the other hand, if you also use some other block explorer to paste your wallet address which turns out not to match yours, would you say they were also hacked at the same time? @OP, you need to change the title of this thread immediately.

That is a clipboard malware. You will need to format your device and reinstall your OS.

If blockchair is hacked, I do not know what the hackers wants to gain because you have nothing to do on the site than to check your bitcoin transactions.

This is why QR code is the best way to make transaction because it can not be changed to hackers address through QR code. But no matter the one we used, it is good we double check the address that we paste.

Ive seen this before in the ETH network most likely in the transaction of the NFT users in the trend of NFT, they tried to copy the address and once they pasted it the clipboard didn't copy this they made another address to cope with, I guess there's a malware that comprises with your device, better to take a run of formatting your device and try to run an anti-virus to make sure your device is safe. Its okay to format than to lose most of your assets.

it only looks at your wallet transactions. if the blockchain is hacked it doesn't cause us to lose our bitcoins right? This is encrypted with a special algorithm so that until now no one has been able to sabotage this coin except with the permission of the Bitcoin owner himself. to this day I still believe in bitcoin because no one can hack it at the front door. if the blockchain is hacked it doesn't matter. This is just a matter of looking at the transaction, it doesn't affect it at all.

Not convinced that blockchain is hacked. If you've noticed discrepancies when copying your Bitcoin address, you should try to investigate potential issues. Check the copied content by pasting it into a text editor to ensure it matches your correct Bitcoin address. Also, run a thorough antivirus and anti-malware scan on your device to check for any malicious software. Always exercise caution and use trusted sources when dealing with cryptocurrency.

OP may be known to be a malware. Just like me at that time when my laptop was infected with malware, when I copied the bitcoin address to make a delivery it turned out that when I pasted it the address changed to the bitcoin address of the malware scammer.

My suggestion is to reinstall your device and reset it. If not, you have to manually write your BTC address when you want to send BTC and make sure you check repeatedly whether your BTC address is correct or not before you lose funds because you sent the wrong BTC to another address.

I don't think it's a block chair that is hacked, as there is no news on the internet, it might be your clipboard that is hacked. As there are many hackers who have the skills to hack the clipboard of the victim and they do it because when the victim copies the withdrawal or deposit address to transfer funds, then that address will be changed by the hacker's address automatically back in the clipboard.

If you don't know that, will paste it and will make the transaction. I recommend you to confirm this by copying the address and pasting it somewhere else in your PC or mobile whichever device you are using. And then check manually if the address is being changed or not.

If it is changed then know that your phone or device has been compromised and it would be better for you to follow the steps to stop them, like resetting your phone, or deleting everything on it, converting you r wallets from that device to another device and the main thing is, do no try to copy the passwords that you might have saved somewhere in your device because doing that will give these password to the hacker as copying password will save it in clipboard and the clipboard is under hacker's control.

Be caution. I am pretty sure the device that you are currently using has been compromised. So please take action as soon as possible. You should erase everything from your device by hard-resetting and installing a new operating system. So the affected parts will be removed, and of course you have to recheck if everything works fine. Before that, you must write down your wallet credentials perfectly to avoid losing your funds. There is nothing wrong with the explores, and it does indicate compromising your device.

I understand that you might be facing an issue where only one Bitcoin or Ethereum address gets pasted when you copy a Bitcoin or Ethereum address. This is a familiar problem that I have dealt with before. To fix this problem, I recommend that you install a reliable anti-virus program on your computer. This will not only help you prevent similar issues from happening again but also keep your device safe from other viruses. I always double-check the address before sending it because of this malware.

How can you create an alarming topic without enough proof? I expect that I will read some useful information or more context in your text, but you only say that someone's address is appearing if you are pasting your address in the blockchair. That's nonsense. What is your reason for suspecting that the website has been hacked? In fact, your problem is so simple; maybe you just copied the wrong address or there was just a glitch in the website that was not necessarily hacked. Next time, before creating such an alarming topic about accusations of some website being hacked, gather information and proof that it is being hacked, because spreading false information about something that you are not sure about is not good.

You could ask first what the phenomenal is, not accusing right away or coming to a conclusion right away because it's not good for the community as you will raise an alarm.

That's the same as I've told him. His device's been compromised so all his data's at risk of being stolen. If there's crypto private keys stored there he's probably going to find he's lost balances. If he hasn't taken your advice he's got to start safeguarding his data before it's too late.

I hope the OP read all the replies here and made quick actions to secure his device and other keys.
Because it is not the blockchair itself here that has issue but his gadget, at least, he caught it and posted here in the forum.
A lot of people can provide him valuable feedback on what's really goin on with the situation.

Knock knock where are you op?  more than 25 good answers and you have yet to reply.

Just the first post.

The Blockchair is just an explorer where we don't need our key to access the website. I don't know what our problem is if that explorer is being hacked?, even the explorer is hacked, it won't have any effect for our balance even we put the right address there. I just remembered long time ago, (but I forget a name a Explorer), I just bookmarked my address on that explorer, but some day when I checked my balance, Looks like there's a transaction which I didn't do so it made my balance going to empty, I bit panic at the time, and open my wallet imediatelly just to know what happen. evidently, my bitcoin is still there, there are no transactions whatsoever there are no transactions like those that occur in Explorer.

Explorer is just online site which could be an error. But we should not panic, because we don't use the private key to access the website. if there are errors and the website ask our key, don't give it, because no one asked the key except the scammer.

I know that something is happening with OP gadget. i do wish that OP read all the coment from other people on the forum so he know what to do.

i think is allright if he doesn't know, as we know other people comment indicate that they already knew what was going on.
Its not a big thing to raise an alarm about blockchair has been hacked

I've seen it happen before. I don't know why they don't reply after they've asked for answers.

I haven't heard any such crypto news updates today. Are you sure you've been hacked? or did you just think it was hacked because you made a transaction here? Maybe you just did something wrong or didn't double check the address you entered.

I hope next time you also provide a source link for others to see here in the forum platform section so that they can also give you suitable advice. Although there are chances that what you say like that will happen,.
