The scammers may use the names of legitimate companies to trick their potential victims into believing the form is legitimate.
Here is an example:
Nestle.wufoo.com
The link to the form above was not created by Nestle, but by scammers. The form has since been taken down by wufoo.com.
Remember, be careful of unsolicited emails or text messages with links to online forms that request sensitive information. And report suspicious or fraudulent forms to wufoo.com, so they may take them down.
