We noted in June that the single most important thing you can do to protect yourself from government spying is to realize that the NSA can turn on your cellphone or laptop’s videocamera and microphone without you knowing.
Now that even the Washington Post reported that your webcam can be remotely activated and you won’t even know it’s on, awareness of this vulnerability has gone viral.
To give you an idea of how mainstream this concern is going, Mashable’s Lance Ulanoff made a short video to show you how to use a post-it to block your webcam (duct tape works, but leaves a sticky mess on your laptop if you ever want to take it off to start using your webcam)
The following from http://mashable.com/2013/12/07/fbi-hacker-bomber/
The FBI's elite hacker team created a customized piece of malicious software, or malware, that would install on a suspect's computer when he signs into his Yahoo email account. A judge in Colorado authorized the bureau to use the malware, according to court documents obtained by The Post.
The malware was designed specifically to siphon certain information from the suspect's computer to the FBI, including location data and websites visited. What's more, it allows the FBI to spy on a suspect through his webcam even without its indicator light turning on.
This is not the first time that the FBI has reportedly used malware, spyware and other hacking tricks to track down suspected criminals.
