Answer: a. keyloggers, screen scrapers
Step-by-step explanation:
When organizations, in an attempt to prevent keyloggers asks customers to not enter characters but instead select them one by one from boxes, intruders may counter with screen scrapers
Keyloggers is a program that allows another person to record the keys struck on a keyboard without the person typing knowing. The person recording can them compile the information to find out very confidential information. By asking customers to select characters this can be mitigated.
Screen Scrapers on the other hand are more lethal because they record that is being displayed on a screen and transmit it to another person thereby enabling them to see what the target is doing even if they select characters from boxes.
