    You're not safe offline: Router LED lights can steal your data


    Have to admit, there are some creative exploits out there....

    A system which is air-gapped is generally considered safe from intrusion as there are few network tunnels or avenues for hackers to exploit. After all, if you can't connect, you can't steal or tamper with air-gapped devices.

    However, this idea has once again been smashed by researchers from Israel's Ben Gurion University, who have demonstrated a method to steal information using the LED lights found on routers and switches used in isolated, secure networks.
    The malicious code has the capability of controlling LED lighting systems and encoding data over them. Once the malware has identified specific information passing through, it is broken down into binary 1's and 0's, which are converted into LED flashes.

    Data can be leaked at a rate of 10 bit/sec to 1000 bit/sec per LED, depending on the hardware infected by the malware. If a router with eight LED lights has been compromised, for example, information can be transmitted at 8000 bits per second.

    Yeah right. This must be the worst hack ever.

    Luckily I keep my router in a closed drawer with the lights disabled then.

    That'll stop anyone spying on my flashing lights - even if they do sneak a hidden camera in to look at them :)

    Can the neuralizer be far behind?

    Sounds like a challenge for manufacturers of routers...Linksys, NetGear, Asus, TP-Link, etc. Time to get busy, guys!

    It's OK, just cover your router in tin foil.

    Another new exploit is e fags plug it into PC to charge and bang malware what next

    Once again the scare monger's are at it. With the release of Vault 7, it seems that everything has gone to hell in a hand cart. Personally I'm sick to death with all this so called scaremongering. If anyone is that paranoid then flog your PC and retire to the Antarctic.

    Wow, that's interesting. I just decoded my blinks and it just keeps saying "all your base are belong to us" over and over again?

    Wow up 1000 bits/sec = 0.125 KB/s (or 1 KB/S if you have 8 LEDS). Hackers would die of old age before they had uploaded anything serious - LOL.
