The BBC has posted a short video on its website that demonstrates what a hacker could do with a trojan horse at his disposal.
The video demonstrates how complex and sophisticated trojan horses are, and how easily somebody could get access to any private information on a victim’s computer.
The videos talks about how a hacker could see the victim’s screen and whatever is on it, read his keystrokes (for displaying hidden keystrokes) and even see the victim’s webcam (scary).
The video is only two and a half minutes long but if you aren’t aware of how clever hackers are, I suggest you take a look at this video.
