The website cashgift.info is a fake Free Cash App attempting to trick potential victims into installing malicious and unwanted apps, take malicious surveys, or sign up for unwanted services. The fake website pretends to be a Cash App Funds Adder app and asks visitors to enter their Cash App username. When I entered a fake username, something I know no one has, the fake website claims it was able to connect to my account. And, it did not even ask for a password.
About Cashgift.info Free Cash App Fund Adder

Cash App Fund Adder
After entering a fake username without a password on cashgift.info, the fake website asked me to select a package.

After selecting one of the packages, it claims I need to complete the human Cash App verification by downloading some unwanted apps that may be malicious.

But, it doesn't matter how many apps you download or survey you complete, you will never get the money you were promised.
