given it was "money from a gov program" they were offering, they were probably the more... dark... kind of scammer.
I imagine they were aiming for full-on identity theft, by getting her to give social security number, bank details, etc... (seeing as government forms need so much information, it would seem "reasonable" to provide it to them)
Right so maybe cloning the identity to take out loans and things, make false papers etc?
Yup, and, being the little malicious monsters that they are, proceed to scam all her friends and family too if they can.
