I'm astonished by how blatant their techniques are. For example, in the "refund scam", the caller pretends to be offering a refund for some tech support contract. The steps are:
- Get remote desktop access to the victim's PC.
- Tell the victim that they must log into their online banking account to get the refund.
- Use "inspect element" to edit the banking page, making it look like victim got too large of a refund.
- Convince the victim that they can't pay back the difference by another bank transfer, but instead must pay it back in the form of gift cards.
It's outlandish. It goes beyond computer-illiterate victims. The victim needs to have a diminished sense of skepticism, which can come from age-related senility but also cultural unfamiliarity, anxiety, etc.
Unfortunately the comments include a lot of casual racism against Indians, with little awareness of the structural conditions causing these scammers to exist.
