#126#64 Hay keyloggers muy elaborados que en cada pulsación del ratón guardan una captura de pantalla de un área pequeña de la pantalla alrededor de la zona donde se ha pulsado el mismo. Copio y pego este fragmento de la wikipedia en inglés : "Screen logging. Screenshots are taken in order to capture graphics-based information. Applications with screen logging abilities may take screenshots of the whole screen, just one application or even just around the mouse cursor. They may take these screenshots periodically or in response to user behaviours (for example, when a user has clicked the mouse). A practical application used by some keyloggers with this screen logging ability is to take small screenshots around where a mouse has just clicked; these defeat web-based keyboards (for example, the web-based screen keyboards that are often used by banks) and any web-based on-screen keyboard without screenshot protection."
#159#64#126 Ejemplo de un keylogger que además hace capturas de pantalla cada vez que haces click: sourceforge.net/projects/pykeylogger/. Este es un programa benévolo, pero puesto que es open source su propio código podría ser usado para hacer un virus invisible al usuario.
