Facebook Messenger now lets users send money to friends

This seems like a really bad idea.  Just find somebodies Facebook credentials, log in, friend an accomplice and proceed to empty the users checking account.  Granted that may be a simplified overview but InfoSec savvy readers & cybercriminals will see how this can be abused.

Comments on this greatly encouraged & appreciated.

Facebook Messenger now lets users send money to friends

As of Tuesday, Facebook has switched on person-to-person (P2P) payments for users in the US to instantly message money to friends.

David Marcus, former president of PayPal and currently Facebook's Vice President of Messaging Products, said on his Facebook page that it's easy and safe:

We're happy to announce that Messenger person-to-person payments are now available to everyone in the U.S.! Add your Debit Card and pay anyone on Messenger in a few taps. Money goes straight from your checking account to the recipient's checking account. Easy and safe. As always, give it a try and let us know how we can make even better for you!
