Dear all,
I would like to explain what happened to me.
On Wednesday evening, I received an SMS from my cryptocurrency exchange, informing me that someone from abroad was trying to log into my account. I was given a callback number and called it.
I went through several security checks with the seemingly professional gentleman. He asked me if I had any other accounts with cryptocurrencies. I confirmed that I had some with Metamask. This gentleman told me that, for security reasons, he would contact Metamask support and forward the case, giving me a reference number.
After that, I received a call from a private number. The gentleman introduced himself as a Metamask support employee. He wanted me to set up three-factor authentication on my Metamask wallet.
He asked me to transfer my 2.2 Ethereum from my wallet (Account1) to another wallet I created (Account2).
He then offered to secure my cryptocurrencies on a hardware wallet at www.ledger.com.pt.Unfortunately, I entered my 12-word security key on this site. From that moment, my cryptocurrencies were gone.
I thank you in advance for your support. I hope something can be done to prevent more people from falling for this. I am very ashamed of how it all happened. Even though I am cautious with such fraudsters and could sense the scam, I still fell for it. Also, because they had the correct names (Kucoin, Metamask) in the SMS. At www.ledger.com.pt, I did not suspect it was a mirrored site due to their professionalism.
