He can try but I think it's just a waste of time because exchanges only address complaints if he is a customer and is using their services. Otherwise, they won't believe what he says or care about his problem because catching criminals is not their job. I think instead of trying to contact OKX exchange directly and not getting any viable results. Instead, why didn't he go directly to the local police to report his case? Catching thieves is police work but this will depend on the country OP is living in, whether bitcoin is legal there or not.

Honestly, other than reporting this to the police, I don't think OP has any way to get the property back. But so far it seems he hasn't done that, which means bitcoin is not legal in his country and bitcoin investors are not protected either.

Relying solely on antivirus software is an inadequate strategy in my opinion.  It resembles wearing a seatbelt while refusing to drive carefully - the seatbelt may assist if an accident occurs, but it won't prevent them.  Similarly, antivirus programs may catch some threats, but they can't shield against everything, particularly if you're not practicing safe online habits.

A multi-layered approach is much more effective in protecting your digital assets. Antivirus has a role but should function as just one component of your OpSec, not the only line of defense.

What he needs is a good hardware wallet because in that case his crypto would be safe even in the case of downloading a malware.


Yep, I was about the write the same thing when I read replies of people l telling him to contact exchange asap. What he needs to do is to contact police asap and let them do their job as they are the only ones who can make exchange to freeze someone else's account.

Having said that, what kind of hacker sends stolen crypto to centralized exchanges? Doesn't make much sense to me but then again, keeping so much money in a hot wallet doesn't make much sesne either.

Keeping 100k in hot wallet is already ridiculous imho. From that point on you can only do more/bigger (security) mistakes with that computer.
That's why I "advertise" hardware wallets. Security is not for everybody and people can make mistakes. Some more easily than others. A HW heavily decreases the chances the mistakes empty your pockets.

If it is PC the problem will likely still persists, because computer is too complex for average users, we think we know it all but yet we get malware on our PC, if this is possible then it is possible to lose the crypto assets you are keeping on your PC.

I can't be confidence enough keeping my crypto assets on a PC, I am too familiar with ways that malware's get into my PC even with antivirus, the problem is Windows PC is the most targetted OS of them all, hackers will always find a way.

The second problem is you will always connect your PC to the internet, this makes it a big failure for keeping crypto assets, if you like do not accept this fact, I will keep saying it again and again, that PC is a bad place to keep crypto assets.

Get a goddamn offline crypto hardware wallet.

Sorry for the lose bro, I believe this incident have serves as a lesson to learn from and never to open any mail that we don't expect to receive. Like others have said, if the thief have not moved the USDT out from the exchange or convert it to fiat into their bank account, then you can use the help of the exchange support to freeze the account but if he already move the asset out, he wouldn't bother to use the exchange again.

I also think that the chance of getting he money back is slim.  The transferred fund could have been converted to another cryptocurrency and transferred it outside the initial exchange where the fund is set or probably it is already been cashed out.  The exchange won't easily block the address or freeze the account without valid documents and I think on the time between the request, producing evidence and presenting it to exchange, and exchange reviewing and validating the documentes and its decision, the fund could have been liquidated already.


Same here I choose ignore mail that have attachment files in it.  It is very dangerous thing even if the file is from a trusted email of a friend because we never know if the file is actually from him or forwarded from someone else.

A police report may not be useful, but court orders or subpoenas are usually very effective. So if OP wants to pursue the scammer, they are going to involve some lawyers and the court in their Jurisdiction. OKX will oblige.

Not that Linux is immune to such attacks, but over 90% is the times, the malicious apps created are only executable on Windows OS. if such an executable file was opened in Linux, nothing would happen, or it wouldn't even be able to execute. That is why I prefer Linux

The bigger lesson he needs to realize is to never store bitcoins on a computer with a constant internet connection and especially with such large amounts, storing them in cold storage is a must. The lesson he learned was that he should get himself a hardware wallet if he continued investing in bitcoin. Say no to storing too many bitcoins in hot wallets and on PC.


The hackers stole all of his crypto assets and are now moving them to OKX for trading. It was too late for him to do anything, let alone turn off the Internet or turn off his computer.

Get in contact with the exchange and explain calmly and in detail what happened. They won't freeze the coins based solely on your story. You must also file a police report and ask OKX about the steps you need to take to have them release the information they have about the owner of that account to law enforcement in your country. They are not going to hand over this data to you and your brother. Be prepared for a long process, and good luck!

You might have a chance if the hacker deposited funds in an account that actually belongs to them and one they did KYC for. But it's possible that they also used hacked or bought exchange accounts. Are the stablecoins still sitting on the exchange or have they been withdrawn in the meantime?

I suggest you also get in touch with the stablecoin issuer to check what documents you need to provide to get the funds in that address frozen.
