We may all have come across capturing and recording our own screen to save some information for ourselves, but how about other people doing so without asking?
Let's have an example here: an attacker somehow gained the access to your device (could be pc or mobile) through malware which bypassed or altered the access control. It silently recorded and captured all the information displayed on your screen, and sent them back to the attacker. Moreover, for mobile devices, the attacker may record your passcode pattern or the unlock process (like typing in the PIN). So,
Is this kind of attack possible?
Is there any solution to defend such an attack? And
What if the attacker combines it with other tools like keylogger etc. to perform a more comprehensive attack?
