Overlay attack

Theft of confidential user information using malware that overlays its own windows on top of another program. When the target application is running, the overlay opens messages or data input forms identical to the real ones. Victims enter information (for example, login credentials or bank card numbers), believing that they are dealing with the original program, but in fact hand it over to the cybercriminals.

One such attack involves overlaying a transparent window over a touch screen keyboard when private information is being entered.
