What token or coin has the address taken??
Has your friend's wallet address previously interacted with Smart Contracts or 3rd party websites??
because as far as I use Mnemonic there are no problems with the altcoins that I have.
I've also lost assets of around 500 busd because I've interacted with smart contracts that are designed to drain the contents in your wallet when you interact with them.

yes, I saw some people who posted lost their tokens in the telegram group.
even the case experienced is the same as what you are experiencing.
we can see quite a lot of fraud tokens in our wallets. so if we suddenly get a token that we don't know about and it turns out to be quite expensive. never expect it to be an airdrop. it will drain the tokens we have in the wallet.

If we take the question at hand, then we can easily say that we are not going to get our mnemonic cracked or anything like that, it's impossible and the power that is required to crack that would be bigger than any server I know of, and if anyone could have done that then I would assume it would have been the famous big wallet of satoshi and not some 300-400 dollar account.

However, about the fact that it was cracked into and money was stolen, I agree that some token situation, or some other way it was designed to get the owner participate a bit was involved, that way they could socially hack your cooperation and then get it directly from you.

I have been hacked twice using mnemonic phrase through metamask. Can't be sure of the reasons both time. After the first hack, I was too cautious not to make any mistake. The only way of my mnemonic phrase being stolen is, I once loaded my wallet in a PC using a pirated/cracked windows os. I can't prove it but I had no other ways of getting it stolen. I was too cautious and had always used a legit OS and it was once event to load my wallet in different PC and just after a week of incident, my balance was stolen. So everyone should be sure that they are not using pirated softwares while dealing with wallets.

I think Mnemonic are safe because many wallet like metamask, Trustwallet we create a new wallet so we use mnemonic through we create so mnemonic are safe way but some time we save mnemonic in that file are email etc which are hack easily then hackers easily open over wallet so secure your system other than mnemonic phrase are safe.

Every security, of course there is a small case that is common, this is natural because it is impossible for all perfect wallets, but whatever the team has done is a big thing that makes everything easier and if a case like this happens massively, of course we can say it is not safe .

mnemonics should be very safe
I've experienced this, and I realized that if I was connected to a site that was infected with malware, I just didn't know which site, and for the safety of my wallet I left it and threw it away from my cellphone and computer.

I'd ask him/her more questions if I were you.
Like where did he save the seed phrase? Was it on the computer? E-mail? Cloud? Or just written on a simple piece of paper which is the safest of all.
How about phishing? Is he honestly telling you everything? How about checking his browsing history?
There are a lot of ways now being done by scammers and hackers to gain access to your accounts.
I never had a problem even in Metamask or other wallet services like Trust Wallet even though it's not recommended to keep your funds there.

Just want to share, I can't prove that mnemonic safe or not. I'm not an expert for things like that.

that mnemonic is safe, depending on how you keep it save. I've experience hold my token about 3 years by keep only mnemonic seed on my flash disk. maybe in this case your wallet have malware or any virus who can access it. so don't keep mnemonic online again and use open source wallet.

Mnemonics are completely safe. It can't be hacked or something that easily unless of user's fault. Maybe OP's friend is not just aware that something happened that leads to unauthorized access to its wallet. They should start looking at the main cause of the problem on the device used as it might be potentially harmed by some malware. OP's friend might also be a victim of phishing.

That case can't just be assumed right away that it's because mnemonic is not safe.

I suggest that you use a new metamask account or dapps app in a new browser, because any connection wallets in third party apps will be very vulnerable to wallet hacking, so we have to disconnect every dapps after we use them, so any potential tokens that have landed in the wallet are recommended to send it to another address for the wallet holder, if we follow the advice above then we can anticipate losing assets in the wallet.

Disconnect only still not enough secure wallet connecting with several dapp exchange exactly with new dapp browser, need to revoke all connection if want secure wallet assets or metamask account. Used new metamask wallet is good option but need to refill fees every time make transaction. Better with disconnect and revoke all connecting after use dapp exchange with metamask connecting. I used beefy.finance for revoke all connecting with dapp exchange, as soon possible after transaction or swap make revoke connecting without have space or time delay could be chance for wallet hack.

In this case, I think OP's friend didn't revoke the previous permissions he granted to an untrusted DEX or dapps. When we connect to dapp or DEX it will always ask us to accept permission and many people didn't notice but clicked full permission button this means they have full access to our wallet. This is a common error and not many people know, after finishing the transaction, we always have to disconnect and revoke all the permissions that we have previously granted.

It’s safe not until you expose those data into hackers or your pc might got the virus which collects personal data. I’ve been dealing with this wallet for years already and so far, I have no problem with some of my token. I support the other claims here that OP your friend might already exposed to hackers and probably downloaded a file from unknown source or it can also be an inside job. I have my crypto friends as well but I’m not letting them to touch my PC without my permission, this is to be more safe.

As hacking softwares or tools are getting sophisticated, your computer will not be safe from hacking or phishing anymore.
These days, we are mostly online and we don't know if we visited the site as potential source of malware or virus.
As much as possible, separate the computer that you are having your funds with, and if possible, not connect it the net all the time.
You can't trace where they will look for vulnerabilities. So what you can do is you need to take care of your own online credentials.
As well as limit your exposure to potential attacks. These hackers don't care who they are dealing with, so long they are exhausting funds.

This is why it is advisable to use a different wallet for Airdrops if you are the type that participates in airdrops however, I too don't think Mnemonic is that easy to break if you did not place them carelessly. Safeguarding your login information can not be overemphasized and connecting your wallet to every site is not advisable too, I would normally write down all my Info in different Dairies and have soft copies of them too, and these devices I never connect to the internet.

Very true, till now many crypto users don't know the great danger of using the main wallet which holds huge amounts of funds to participate in airdrops, especially those that will require the user to connect to the website. It is through this process and other ways that a hacker can have access to one's wallet. It is very important to take note of this and other possible ways like always disconnecting your wallet completely from any site you connect it to, ever since I read about wallet disconnection, I try to make it a point of duty to do so.
Mnemonic is very safe the way it was used is the problem.

Mnemonic phrase is hackable is hackable, Though there are several types of way to hack that like phishing, hacker having access to your computer and many more way to hack that secret phrase of yours but I will personally use and recommend it since I haven't experienced being hacked yet. I think it is safer compared on using custodial wallets that is much more prone to hacking or being removed to access to your own funds. Everything is hackable, It will depends on how you will keep and manage the security of your own assets.

Your friend must be careful in using it. instead when we login in metamask or the dappps application, if he is an airdrop player or the like, try to pay attention to the incoming token, there is a possibility that it is a dusting token. This is what makes your friends' wallets likely to be broken by hackers, they are very clever, even a small gap can be an opportunity for them.

There might be some part of the story that we didn't know since OP just conclude right away that it's because of mnemonics being not safe. OP should look at all sides of the case starting from the hardware/devices that were used or might be his friend did some unintentional action that is not aware of.

Technically, mnemonics are safe and can't be breached that just easy. Although I'm not really aware of this Coin98 wallet and I'm confused about how on earth your friend ended up with a wallet that I can't even consider as popular or reputable.

I experienced it, it is a multi-chain wallet like trustwallet and has all versions for browser and phone. My experience is that it is quite slow and quite difficult to use if you are newbie, but in terms of security, I have no problem with it as I have used it to store some assets worth more than $1k. I think it's not the wallet provider's fault but maybe the OP's own fault, maybe he connected to a phishing site or his computer has a virus...In this case, he can try contacting coin98 support directly to get it resolved instead of asking here.

Mnemonic are safe but your computer is not so most probably your friend pc got compromised and that’s why he get hacked. Hackers can’t get your money unless you publicly post the details of your wallet or you downloaded a malware that can get your informations easily. That’s too back to get hacked, and a costly lesson to be learned. Well, better to secure your wallet and make it your outmost priority.

I'd see this stance happens mostly to those who lose their private keys or Mnemonic. It is very understandable that once our PC has been attacked by malware, it was easy for the hackers to control on it. Things that we need to keep in mind - there is no safety assurance storing our password/keys in the computer as it was advisable to right it dows in a paper for more safety. Definitely, there is no problem with the Mnemonic, in fact, many people are using this. The problem is that the one who manage to keep those stuff. Usually we neglect to do it.

The wallet was hacked, but I don't think it has anything to do with his mnemonic phrase, except someone else had access to it. Otherwise, I believe this hacking may be attributed to interaction with a malicious smart contract.
