Hey a quick warning post (which hopefully isn't too late for anyone) and a reminder either way.
Pancake swap was possibly DNS hijacked earlier today with some users who were trying to visit the site seemingly being redirected elsewhere and asked to enter their seed phrase or private key once redirected.
If you give you private key or seed phrase to unknown parties they can access your funds and do what they want with them (you probably won't like what they do with them and you will never see the coins or tokens again).
Never enter your seed phrase into websites, if you get emails from ledger/stellar/Vitalik Buterin himself (you won't) and they ask you to download an update or enter a seed phrase anywhere it is a scam and you will likely lose funds.
Also, generally if it sounds too good to be true it probably is.
If you had tokens on PancakeSwap and didn't put in your phrase anywhere you shouldn't have then your tokens should be fine but wait and watch their Twitter for updates.
