The founder of Rotkiapp, Lefteris Karapetsas, theorized that “It's DNS spoofing. Cloned the site, made the DNS point to their ip where the cloned site is deployed and added approval requests to a malicious contract.” Curve retweeted the theory in apparent support before following up with a further announcement;

Don't use https://t.co/vOeMYOTq0l site – nameserver is compromised. Investigation is ongoing: likely the NS itself has a problem
