Are AML verification sites safe to connect your wallet to?

[ALMN]

There is someone I wanted to buy from, but he asked me to scan/check my wallet address through a website. When I opened the site, it asked me to connect my wallet to perform 'AML security checks.' My questions are:
1- Are these tools actually safe? If yes, what are the well known and trusted sites?
2- Why does it ask me to connect my wallet instead of just asking for my address and providing a link to pay the fees as a direct transfer?
3- If these are scams, what is the scam mechanism?
4 -If I had connected my wallet back then, does it mean they only had control at that specific moment, or is the impact permanent?

1. If you have to connect your wallet? I would be concerned. Blockchair seem to do that for you when you search for your address (through third party apps), AMLBot also give you one scan for free (through telegram I believe). I'm not sure there are any advanced tools that are free to use.
2. You're asking the right questions.
3. When the service ask you to connect your wallet, you're more likely to confirm or sign a transaction you shouldn't have and that's when the scammer could get access to your funds. (You could be signing a transaction that's sending all of your balance to the scammer's address).

Feel free to share the website so we can confirm this.

It is as simple as what OmegaStarScream posted, do not connect your wallet. Connect noncustodial wallet scam has been very common since more than 2 years ago.

AML check does not have to do with connecting wallet, only the address that you want to check is what that is needed for it, not connecting your wallet.

First of all your wallet shouldn’t even be online except that’s not your primary wallet for storage. So it been online is actually not safe talk more of connecting to any site. No one can actually gurantee the authenticity of it, because there is possibility of it falling into the wrong hands (hackers).

So my outright answer is, it’s not safe

A seller and buyer (if p2p) has no business with each others wallet or connection, except you’re buying from all this DApps which asks you to connect wallet and it is very dangerous as most of them are for scammers and they can be trick you into sign a transaction that hand overs your wallet details to them. This is same as phishing attacks

[Odusko]

Be very careful because most of them are scam, while some AML checker are legitimate, like chainanalysis, Elliptic, both are used by exchange and other regulated institutions, but does not require your wallet connection, any site or services that ask you connect your wallet is a big red flag sign, because their have full access to control your wallet the moment you have it connected to their service.

If he connects his wallet, the next step is the scammer to only trick him to sign a transaction on the wallet and his money gone just like that. It is good that he asked the question on this forum, else he would have been scammed. But we can not conclude that  this is the same as phishing attack if we did not know how the scam began. If ALMN searched for it online and see the scam site or if he is the one that looked for the scammer, it is not a phishing attack.

Hell nah, that's suspicious AF. Never connect your wallet to those sites. Honestly, if you have connected, whether you have leftover funds or nah, always assume it is compromised and abandon the wallet—move funds to a safe wallet if any.

You could also use bitmixlist's AML checker, this is made my someone reputed on bitcointalk, see their thread: https://bitcointalk.org/index.php?topic=5477452.0

It is not free but still at cheap price IMO. Probably has better privacy terms too as oppose to other means who probably tracks your IP and browser fingerprints.

1. I use a tool once that's being used by other members here too but it didn't require me to sign anything. I think they're safe if you don't have to actually sign with anything. Check @btc_aml_bot on telegram, they are 100% safe and legit.
2. Because they are scam and they might want to inject or hack your device.
3. I think that signing stuff is a bit sketchy, that is a common red flag. I wouldn't dare to be curious more than that by testing it, maybe on a device that you haven't used before and don't have any assets or files that may be compromised after experimenting with that site.
4. Could be both, best to perform a security check (moving funds to a new wallet) or revoking your wallet from that site. Check revoke(.)cash for that.

That’s already shouting scam. What’s the connection between your wallet and their so-called verification. If they really want to check something, it should be based on the address you’re using, not by asking you to connect your wallet.

Don’t fall for that. The moment you connect your wallet, it’s basically like saying goodbye to your money.

It’s just common sense. We don’t even feel safe leaving our funds in exchanges sometimes, so why would you trust an unknown platform asking you to connect your wallet under the excuse of KYC. If you fall for that, you’re just putting your funds at risk.

[electronicash]

the fact that you are asking these questions before you connect you wallet, you already been suspecting something will happen. there have been incidents like this before where wallet connected to a dapp and the ETH inside the wallet was gone after few minutes of logging in.

sure there are scams like this. the mechanism i believe is that when you login, you input your seed which if you do this, the seed will be saved to a text file somewhere in their server which the malicious user can just login the wallet and swept them all.

The best solution is not to link your wallet to any website you don't trust. However, there are steps you can take to minimize the risk, such as:

 - Checking the website using ---> https://www.virustotal.com/
 - Linking a new wallet with a small amount, for example, $1, to check if the website is scam.
 - Do not link a wallet with a large balance to any unknown website.

Its public blockchain. You don't need access to a wallet to perform anti money laundering checks. You don't even need permission, you have the address, everything is checkable on the blockchain.

For me, there is no reason, and without proof, I would 100% say its a malicious attempt against you.

Check with an actual AML service if you want to understand how it works. Like AMLBot, all they need is an address. Businesses pay per address check.
