It’s classic phishing, abusing Free online forms. If you click, you will see the next set of messages:

Why do such simple attacks still work? Well, in Latin America, in the good sense of this word, people are very naïve. It’s clear that attacks do not need to be complex to be effective. Simple tricks used 10-15 years ago are still functioning for cybercriminals. And as you can see, there is no need to clone an original Web site, so any rookie cybercriminal is able to use such methods to steal users’ information.

I already reported the form as fraudulent and hope it will be taken down quickly.
