Thanks to one of our readers who submitted this interesting piece of phishing. Personally, I was not aware of this technique which is interesting to bypass common anti-spam filter and reputation systems. The idea is to create a fake survey on a well-known online service.
In this case, the attacker used surveygizmo.com[1] which offers you to build an online presence for surveys or feedback forms. Most of these websites are paid services but offer free trials. Enough to build a phishing campaign.
The generated link is sent to the victim as usual with some social engineering. Here is an example of the link:
hxxps://www[.]surveygizmo[.]com/s3/5485786/Invoice-4982550
The landing page looks like this:

Clik here to view.
(Note the typo "your o email")
And, once you provided your credentials, the survey immediately ends with this screen:
Image may be NSFW.
Clik here to view.
The attacker just needs to login on his account to access data submitted by victims… You don’t need to deploy or hack a server to host the phishing page, you just use free resources provided by a cloud service. Pretty clever… And, if you’re ready to pay a small fee, you can even build self-branded surveys to increase the chances to lure victims.
