It is not safe - Move Your Funds Immediately

[VanguardVale]

I am just here to warn you guys if you have been using walletgenerator.net there past few months, here's a good read for you.

Who is affected:
Anyone who has put funds in a public/private key generated via WalletGenerator.net after August 17, 2018.

When:
August 17, 2018  -  ?. While the malicious behavior is not presently found as of May 24, 2019, it could be reintroduced at any point.

What happened:
There were changes to the code being served via WalletGenerator.net that resulted in duplicate keypairs being provided to users. These generated keypairs were also potentially stored server-side.

What you should do if you are affected:
Securely create a new keypair/wallet and move your funds to that new, secure address. Some folks have recommended using bitaddress (offline) via https://github.com/pointbiz/bitaddress.org.

Though this is old but thanks for sharing. I know some people who lost their fund already! I told them not to trust any third party website or app, but they said it is safe and million people use it! It doesn't face how many people using it, the fact is anytime it can breach and you can lot every fund from there! Only a hardware wallet is a solution now and forever, Ledger X has smartphone facility too! Everyone should avoid walletgenerator now and forever!
