Did you see what sorts of seeds it was generating?

Does it look like they were "random" or just one generated repeatedly? If the latter, we could report the addresses it produces also to the projects that mark tainted coins.

It's nice to see you included the source of the phishing attack too, search engines are always a pain with ads (especially Google for not moderating them).

I checked the site some minutes ago, it can not be used to generate new seed phrase, you can only input your existing seed phrase on the site, which means it will only be used to hack private keys and seed phrase, it is definitely a site for hackers. Although, it is proving to work offline but I do not believe this, it will have a kind of malicious malware.

Ahhh! In that case I'd also recommend bookmarking the real site and taking your computer offline before putting in any sensitive information anywhere (Cross site scripting and accidental back doors are always a problem even with legit sites).

The legit site has its guide on offline usages but I am sure many newbies don't care to read the part or they even don't care to scroll down computer mouse to read all information and guides on the site.

As an offline reminder for all:
Wallet creation (offline) - Wallet backup (offline) - Backup storage (offline) - Wallet recovery (offline).  

Offline Usage

You can use this tool without having to be online.

In your browser, select file save-as, and save this page as a file.

Double-click that file to open it in a browser on any offline computer.

Alternatively, download the file from the repository - https://github.com/iancoleman/bip39

The site can not be used to generate seed phrase, also why is it mimicking Iamcoleman with the same version (v0.4.3). I will advise people not to use the site.

From Iamcoleman site, seed phrase can be generated
                                                                                                         
                                                                                    From the other site, seed phrase can not be generated.

Ok, so if you input your seed phrase then it can steal obviously steal your bitcoin. And this kind of websites has bots as well, if you input everything in matter of seconds then can get everything from you, and you don't know what really happen until it's too late.

This one, we have seen so many fake and phishing websites in Google Ads, but they won't react until it is reported. It's good that this website is no longer showing, however, the website is still up and perhaps a report to: https://safebrowsing.google.com/safebrowsing/report_phish/?hl=en.

The OP included the original site you we can reference it when reporting it to Google's safe browsing.

people shouldn't be using their secrets (private keys, mnemonics,...) on an online computer let alone enter them in some website inside their browser. there are lots of ways they can easily lose them and one of them is the site being malicious. even if you visit the real website you still have no way of knowing what the backend is. not to mention you can have keyloggers in your system or some vulnerability in your browser,...

the only safe way is to use open source software (ie. downloading the source code) of only popular projects or those which you can verify yourself and running it on an airgapped computer.

Isnt this the program you have in the nano ledger wallet if you want to confirm your seed is correct?  Or is this something else?  What is confusing is someone said if you ever want to check if you seed in your nano ledger is correct, go to a program which i thought is this program and then type it in to see if it check mark or not?

<...>

The procedure described by Ledger, using an Coleman's non-fake BIP39 tool, is to gain access to a list of all your private keys (see https://support.ledger.com/hc/en-us/articles/115005297709-Export-your-accounts), which you can then import into certain alternative wallets (although you may be able to do so just using the 24 word mnemonic).

Ledger has a recovery app that allows you to verify that the 24 word mnemonic you have is correct, without having to go outside Ledger’s ecosystem: https://support.ledger.com/hc/en-us/articles/360007223753-Recovery-Check.

So the ledger recovery app that allows you to verify if your seed is correct.... has nothing to do with the coleman bip program then?
