Try to imagine how much bad stuff we could keep off our computers and networks if we could figure out a way to filter incoming traffic from the Dark Web. Well maybe we can.
First, my apology in advance to my non-technical followers, this article may be a bit high level for the average user.
A post in Spiceworks from “Born2Frag” goes into a fairly involved process to block traffic coming from Tor exit nodes. In the discussion following the lengthy technical tutorial, other security pros discuss whether this would be effective, and problems such as how this could be subverted with Tor private bridges.
Nevertheless, it was a clever idea. A lot of the worst exploits, including nearly all of the crypto-ransomware variety, send installers to compromised systems via the TOR network, and blocking the exit nodes would seem like a good way to stifle that sort of malicious traffic.
And another shout out to my coworker, Tyler Ott, for sharing this Spiceworks post with me.
