@Rikafip. It appears your joke on the hack being done by the Lazarus group was really a good prediction hehehe. However the skeptical me asks, is it confirmed that the hackers who hacked stake.com are really done by the Lazarus group? Similar to what you said, anything presently could be blamed on North Korea. I reckon the DOJ also used the Tornado Cash and North Korea storyline to force an executive order. What is their new agenda?

Also, I am very much in doubt that the hackers would accidentally connect their addresses by mistake. This might be intentional.

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

edit: i found archived snapshot from June 20th and there you could see the details. What's interesting though is that just a few months ago they allegedly had $182 million in their reserve and now it fell down to barely over $20 million.

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.

I see the amount but nothing else other than that. Was there more info yesterday, like how much of each assets they have etc? Somehow I can't remmember whether it was there last night when I checked their CMC profile.
-snip-

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) :

Am I the only one who can no longer see the reserves now?

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.

all the assets that were hacked are linked to smart contracts, and no loss of Bitcoin (BTC) was reported.
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.
https://twitter.com/coinexcom/status/1701662057496731975


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.

It is larger than $ETH, $TRON, and $MATIC. There is this transaction https://explorer.chainweb.com/mainnet/tx/GI4z8v-qMPb8a594CMdARfJ-83SzDTXUNYEpIv3mVqQ

2,214,700.00 $KDA ($1,127,371 USD) From CoinEx to unknown wallet

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.

Tweet is back as it can be seen in my previous post, including that part about compensation.
I saw the tweet now, and I am impressed with the way they address the issue, and they assured people that their funds are safe and not tempered with. I hope they keep to their words because centralized exchanges now are not to be trusted.

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.

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? I mean looking at their trading volume and their "reported reserves"?[2]

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.

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 “

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:

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?
