With the recent upgrade from single collateral DAI to multi collateral DAI, there was a scammer preying on those who weren’t careful.
They set up a website/dapp claiming to perform the token upgrade for you. My wallet’s process for doing so wasn’t loading so I searched for a way to do it, and ended up on that scam site. The site looked quite official too, with a decent domain name and all.
I was the first to fall for it, but fortunately only lost about $20. I can live with that - the price for my stupidity. Others who followed me weren’t so lucky. A few unfortunate people lost well over $1000 in the process.
Thankfully the site has since been taken down, and flagged as a scam in a few places.
So just remember to be careful when using third party sites, folks.
