This is an exchange I have had good experiences using.

It is the next rising star to take the place of the freedom Kucoin used to give people.

Thanks Coinex for all you are doing !!!

Good to hear that people are able to withdraw their money, and hopefully some of those affected learned a valuable lesson not to use centralized ecxhange for storing their crypto.
We can't blame them since most of the traders these days are looking for exchanges where KYC is not mandatory like Coinex.

By the way, I assume that you were able to withdraw your money fully?

Yes, most of the coins right now can be able to withdrawn except for the remaining 300+ coins/tokens according to the OmegaStarScream statement above.

-snip-

They actually announced a couple of hours ago that it's now +340 crypto/tokens. Here's the list of assets/networks[1]. I guess that's good enough, even if someone has something he can't withdraw, he can always trade that to something else, and withdraw it.

Some good news for those who have their funds stuck[1], you should be able to withdraw your funds starting tomorrow (21th September, 8:00 UTC). Make sure to not use any of your previous deposit addresses if you're planning to continue to use the exchange, because they won't be credited to your account.

To those who deposited last week that weren't credited to their account, you should submit a request to Coinex support including the screenshot of the transaction from the wallet and the transaction ID.

Here's the link where you can request below and then issue type "Deposit not credited"

Poking around a bit and talking out my A$$ but I don't think the wallets were actually compromised but the back end that talked to the wallets. More like the withdrawal server was compromised. There were other tokens and things associated with a few of those addresses that were not moved until coinex moved them hours later.

Could be I'm missing something obvious, but if they had access to the wallet server(s) and the private keys everything in those addresses would be gone. IMO.

So their 'preliminarily determined that the cause of the incident was the leakage of the hot wallet private key' is either wrong OR the people who took the money were incompetent OR as I said, I am missing something.

This can easily be referred to as an “inside work” hypothesis, especially since it will not be possible to prove otherwise if the identity of the hacker is not known, or at least the method through which the hacking occurred.
I don't think that "inside job" is a valid theory in this case if what they are saying is true, that hackers used address connected with the recent Stake hack.


I have been following the updates since yesterday, and there is no talk about ongoing investigations or possible hypotheses about how the hackers were able to access the private keys of the platform’s hot wallet, or about ways to track the stolen funds after the addresses to which they were sent were identified.
The only ones who can give answers to that are Coinex people and since it happened only few days ago, it will take some time before we get an official explanation what exactly happened there. Then again, this official explanation might be a bullshit story too in order for them to look good. In the end, how hack happened is not as important as a lesson I hope some people learned, not to store their coines on centralized exchange.

This is what CoinEx is saying, is it possible for them to lose over $70m and still compensate every user who lost funds 100%, or is this just 'good' PR so those who are affected would remain calm, i find this 100% compensation thingy very hard to believe.

CoinEx is not a big exchange, so i don't believe that a $70m loss is:

a small portion of our total assets
We'll see what they plan on doing in the coming months and if they are true to their words.

These amounts can be considered huge compared to the market value of the platform and its daily trading volume. The platform is not popular compared to its competitors, Binance, Coinbase, and others. Therefore, their success in securing users’ lost deposits will strengthen their position in the market.

- 70M $ in assets has been lost.
Time to update the guess title I guess.  Tongue

It remains to be seen, but considering the fact that amount lost is almost the 3x bigger than their daily trading volume, I would be very surprised if everyone gets their money out fast. Fingers crossed though.


Are people who still leave their funds in exchanges seeing these recent events: https://remitano.com/forum/ng/134684-latest-updates-on-recent-security-incident-on-remitano
It doesn't matter. Even if what hapepned to FTX happens to Binance/Coinbase, people would still store their money on centralized exchanges. Barely anyone (including those that lost money there) learned any lesson from Mt.Gox fiasco so why would now be any different?

So they just released this a couple of minutes ago: https://coinex.medium.com/coinex-updates-on-recent-hot-wallets-hack-780a600dc846

But in short:

- 70M $ in assets has been lost.
- They're planning to finalize the wallet upgrades by next week, and gradually resume withdrawals.
- Users funds will be compensated fully.

Can someone tell me if these "hot wallet private keys" are just saved on their platform's server, i mean on their hosting servers for them to control the withdrawal on their user's daily withdrawal, then just replenish the addresses if it lacks balance on it. Because if its the case then it'a easy much easier for hacker to compromised such thing.
The deposits and withdrawals system usually has a separate server where the private keys are placed here. From there, the main system sends it a list of addresses for the amount to be withdrawn, and the deposits and withdrawals system carries out that, ensuring that there is a sufficient balance for withdrawals, and transferring any excess balance to cold storage.

Hackers can steal money in two ways: either by accessing the servers of the deposits and withdrawals system, that is, accessing the private keys and withdrawing currencies, or by manipulating the basic system so that the deposits and withdrawals system sends a withdrawal order for a specific amount to the hackers’ address.

I do not know how the hack occurred, if it was to the system of deposits and withdrawals, then in most cases after restoring the system, users will be asked to stop using the old addresses, but if it is in the basic system, then in most cases users will not be asked.

The exchange just issued an official statement about the matter[1]. According to them this is just a small "amount" of what their reserves have, and affected users will be compensated. Am I the only one who finds this a bit hard to believe?

One of the Tweets mentions:
Quote
We assure all users: your assets are secure and untouched.

When you come up with this kind of bs after 40 million in coins definitely leaving your wallets it's pretty hard for anyone to take them seriously on this matter. No, the assets are not secure and are not untouched, as we speak they are getting touched by thousands of people in some swaps. I do kind of feel bad for Coinex being a relative old guard exchange but with the amount of shitcoins it listed it never managed to ure me into creating an account.

And here comes the usual stuff, united we stand, we will overcome, we need more time to investigate, c ya!

According to the statement, the cause of the incident was the leakage of the hot wallet private key, and the assets in CoinEx cold wallet have not been affected.

There's not much to say here. Obviously, if they wanted automatic withdrawals from the platform, they'd need to store the private keys for transaction authorization somewhere. We don't know how they kept these keys secure or who could access them. The leak might have been due to hacking or simply an inside job.

The platform confirms that all those affected will be compensated and that the hack was only able to acquire a small portion of the total assets on the platform’s hot wallets.
Good thing if it's the case, or it's just a cover up story to let its users not to panic, but let's hope it's the other way around.

In the latest update issued by the blockchain analysis company PeckShieldAlert, it is reported that the CoinEx platform has lost the equivalent of $43 million, which is the total assets on different network chains.
https://twitter.com/PeckShieldAlert/status/1701731944340562107

Referring to the latest updates from the CoinEx platform, this number of losses was not announced, but rather it was announced that only the equivalent of $31 million was lost and that the addresses used by the hacker were identified. The platform confirms that all those affected will be compensated and that the hack was only able to acquire a small portion of the total assets on the platform’s hot wallets.
Currently, all deposits and withdrawals have been suspended until it will be announced, and this in itself is considered a loss for users who have lost access to their savings, and they will certainly not be compensated due to the disruption.

It is a new opportunity to remind once again that one of the most dangerous steps is using platforms for long-term storage of a large value of assets.

Hm are you sure? In one of their tweets Coinex mentioned this BTC address ( 1BHNb9UJy4cWFB5wywZkTVgoNB4JbFmswH) as part of the hack and there's currenly 231 BTC there worth almost 6 million dollars.
I searched some articles and they did not mention Bitcoin. I activated notifications on the scammer’s address: https://blockchair.com/bitcoin/address/1BHNb9UJy4cWFB5wywZkTVgoNB4JbFmswH. I think they will use one of the available mixing services, to see what is the best alternative to CM that these hackers prefer to use. 54 million is not a small and I fear that companies depositing their currencies with Coinex will exploit it by withdrawing all liquidity in the coming days, which may lead to bankruptcy.

@Rikafip. It appears your joke on the hack being done by the Lazarus group was really a good prediction hehehe.
Well, they usually blame them for these type of hacks so it was pretty much safe guesstimate  Tongue


However the skeptical me asks, is it confirmed that the hackers who hacked stake.com are really done by the Lazarus group?
I don't think that is possible to confirm with 100% certainty that they were behind Stake hack. Iirc, "evidence" was more in style that it has elements of classsic Lazarus Group attack or soemthing similar among those lines.


Also, I am very much in doubt that the hackers would accidentally connect their addresses by mistake. This might be intentional.
Maybe, mabe not. Even smart/capable people do stupid things sometime.

I reckon the DOJ also used the Tornado Cash and North Korea storyline to force an executive order. What is their new agenda?

Perhaps the financial reserves data is automatically retrieved from their hot/cold wallet addresses. Given that many of those wallets have been drained (and Coinex may have made some transactions themselves to safeguard the funds), this could explain why the total has decreased significantly and why there is no longer detailed data showing individual token allocations.
Yeah I guess that's the reason for such a dramatic decrease. Anyway, situation doesn't look good at all and I hope that not many people here have money on Coinex.

According to @zachxbt, it looks like the same group that recently hit Stake is behind Coinex hack as well (connected addresses). Here is tweet with more info and proof https://twitter.com/zachxbt/status/1701905899034390574?s=20

You can actually copy the addresses from the website archive and check them in the blockchain explorer. The ones I checked do indeed show the withdrawal of all assets in the last 12 hours.

Yes. They had the list of assets as well as the addresses and the amounts on them yesterday.

So I just checked some of the addresses from the link you posted, and it looks like they were targeted:

https://etherscan.io/address/0x53eb3ea47643e87e8f25dd997a37b3b5260e7336#tokentxns



We can see here that funds were sent to the hacker's address, and then to what looks like Coinex address that still have funds (50M in Ether, and 20M in tokens) :

Since this is "Reported directly by the exchange" as mentioned on CMC, I would imagine that the only reason the data is not showing is because CoinEX no longer wants it to show... and if that's the case, that's even more worrying.
Yep, if they really changed something here then it probably means that situation is far more serious than they want their users to believe.

It's a PR bullshit of course in order to calm their users but I doubt that anyone is buying it, at least not those that bothered to check their numbers. I mean, their 24h trading volume is ~$30 million, "reserve" is ~$32 million while hackerd amount is in range of $18 to $27 million. Small amount my ass.

I read some reports that talk about 27 million, and if this is true, I doubt their ability to compensate users 100% without resorting to spiraling loans that may lead to bankruptcy.
27 million is the old number, latest one is 54 million and that's probably not all. Hard times for Coinex, I have no idea how will they sort this out and survive considering their volume, size of their "reserve" and the amount of money stolen.

The last one was Staked.com. Although Stake is not an exchange but a gambling site, but it is still centralized and holding customers fund on hot wallet which makes them vulnerable to the hack. Centralized exchanges that have been hacked before are because of the hot wallet that they are using.

Not good to hold coins on exchanges. If $18 million worth of coins  is stolen from the exchange, it is not going to be easy.

Edit: I do not know how true this is, that more coins are stolen. That $27.8 million in ether, tron and polygon has been stolen.

There is a difference in size stolen compared to size of company, however. Stake lost $41 million according to some reports but their monthly revenue is very much larger than this which implies that they will make this stolen amount back within 2 years.

On Coinex, it is a small exchange with a 24 hour trading volume of only $25 million. The impact of this hack is bigger, I reckon. Also, this is the bear market. Revenues will be much lower.

From the initial $18 million, the estimated amount stolen is now north of $30 million. That's according to a blockchain security firm. Surely, that's not anymore a "very small portion." That's already bigger than their 24-hour volume. Further investigation might still change this number higher.

Even in their statement you can feel a lot of pressure. That's obvious, especially when they say that "We assure all users: your assets are secure and untouched." followed with "Affected parties will receive 100% compensation for any loss due to this breach." LOL! 

Their token has also suffered a double-digit decrease in value. Things don't look good for them.

Let's see if they will reactivate the withdrawals any time soon to make their claims true and not just start giving more doubts to their users. It also allows anyone to make sure the amount of large reserves they have. Another drama is about to start.

Preliminary assessments indicate unauthorized transactions involving $ETH, $TRON, and $MATIC. The precise amount of the loss is still being determined, and the affected fund is just a very small portion of CoinEx’s total asset.

I hope this is true, though they have assured that the business will continue to run as the amount stolen is just a small portion. Personally, I'm a bit worried because $18 million+ stolen, in my opinion, is significant, especially considering that this exchange has only a daily trading volume of just over $28 million according to CMC.

When Binance (or any other centralized exchange for that matter) could have been trusted? Crypto exchanges kept failing from the early days (e.g. Mt.Gox) so only a fool would trust centralized platforms.
Some people still leave their coins on exchanges like Binance, KuCoin, or even exchanges that do not require KYC because they believe those exchanges have a reputation and will be around forever, not realizing that those exchanges also encourage hackers to hack, just like others they believe do not have a reputation.

With all of the headlines regarding CEX hacks, why are some users still keeping their coins in their possession? That is the question I am always asking. I understand that CEX has the most advanced trading features, however they cannot be trusted with our funds.

There is no more trust in centralized exchanges, irrespective of their reputation in the world; even Binance can’t be trusted anymore with all these careless or fake hack news stories just to go with people’s funds.

The first tweet reference was deleted, which means that they might not compensate anyone as they promised.

With their trading volume it means they have so many people that fall victim of these hack, that is why it is always advisable to keep our coin in our personal wallets. ”Not your keys, Not your coins “

Am I the only one who finds this a bit hard to believe? I mean looking at their trading volume and their "reported reserves"?[2]
It's a PR bullshit of course in order to calm their users but I doubt that anyone is buying it, at least not those that bothered to check their numbers. I mean, their 24h trading volume is ~$30 million, "reserve" is ~$32 million while hackerd amount is in range of $18 to $27 million. Small amount my ass.

By the way, that tweet with their announcement is deleted for some reason, here is the new one https://twitter.com/coinexcom/status/1701651414991397176

The exchange just issued an official statement about the matter[1]. According to them this is just a small "amount" of what their reserves have, and affected users will be compensated.

but deposit and withdrawal can be suspended while other things on an exchange can be working good. Were you able to withdraw some of your coins on the exchange?
In fact, I did not try withdrawals because fortunately I do not leave my assets on the exchange for a long time. I withdraw them permanently and deposit only when needed.
I tried withdrawing and depositing is actually suspended:

Edit: I do not know how true this is, that more coins are stolen. That $27.8 million in ether, tron and polygon has been stolen.
Yeah I woulnd't be surprised if number is bigger than initially reported $18 million, like it was on Stake case as well.  I can see those Lazarus Group guys from North Korea being accused of this hack as well.  Cheesy


I tried to contact them just now and it's confirmed that they having some issues all withdraw and deposit is currently suspended.
Hah, that's almost as good as official confirmation that they have been hacked as they woulnd't suspend deposits and withdrawals if it was business as usual.

The news has not been confirmed yet. I have been working on Coinex for years, but I do not trade on a daily basis. When I heard the news, I logged into my account and there did not seem to be anything strange, not even an announcement about hacking.

I also went to the official Twitter account of Coinex. There is no news about hacking either, the exchange website is working normally so far and nothing strange.

We have to wait for an official confirmation or denial from Coinex.
Did you see what BitMaxz posted? He said that withdrawal is not more working. The website of a trading platform can be working good, the trading and all other services they are rendering can be working good, but deposit and withdrawal can be suspended while other things on an exchange can be working good. Were you able to withdraw some of your coins on the exchange?

That's bad news I'm using Coinex to trade and transfer some coins from Viabtc to Coinex.

I tried to contact them just now and it's confirmed that they having some issues all withdraw and deposit is currently suspended.

I asked them about the news and this is what they said.

The last one was Staked.com. Although Stake is not an exchange but a gambling site, but it is still centralized and holding customers fund on hot wallet which makes them vulnerable to the hack. Centralized exchanges that have been hacked before are because of the hot wallet that they are using.

Not good to hold coins on exchanges. If $18 million worth of coins  is stolen from the exchange, it is not going to be easy.

Edit: I do not know how true this is, that more coins are stolen. That $27.8 million in ether, tron and polygon has been stolen.

Another day, another hack and it time seems like its Coinex turn. Still waiting for the official confirmation from Coinex though, for which will probably take some time.

Edit: iunfortunately it has been confirmed, hack indeed happened https://twitter.com/coinexcom/status/1701651414991397176
