Bluetooth Keystroke Injection – Mitigation

Summary

Excerpt From Bluetooth Vulnerabilities (Part 2) Webinar
This Short Video, Presented by CTO, Dr. Brett Walkenhorst, Will Show You More About Keystroke Injection Mitigation
Keystroke injection attacks carry the risk of introducing backdoors, unauthorized data access, malicious malware, and total system penetration. This video discusses how important it is to reduce risk by being proactive. Dr. Brett Walkenhorst talks about how groups can improve their Bluetooth security and lessen the chance of assaults by keeping a close eye on the airways for unusual activity.

Course for keystroke injection, the impacts are huge. Right? You can execute code. You can compromise the system completely. You can get access to whatever data you want, install a backdoor, really the sky is the limit you have hid access to your target device. You can do whatever you want.

So that's huge. You don't want this kind of stuff happening. What can you do? I said this before, update your systems. The good news is that these kinds of attacks are focused on systems where people pay a lot of attention And so if, you know, if you're vulnerable, it's it's relatively straightforward to update once the system has been patched.

In contrast, when it comes to keyboards, there isn't really a typically it's not a good mechanism for upgrading firmware. So when there's a vulnerability in a keyboard platform, Typically, you're gonna wanna replace your keyboard. And if it's more than a couple years old, you might wanna consider replacing it just just because it doesn't doesn't confirm that you're really secure, but it's a good step in the right direction just to keep things fresh.

And the other thing you can do is monitor your environment for Bluetooth packets to identify odd pairing processes. And one example of this might be, like you could if you have location information with your monitoring system, You can identify when a keyboard post pair are dramatically separated in space.

Like, why maybe I have this pairing that aggregated. It's close together in some location. And then suddenly, the keyboard is halfway across the building. Why would that happen? Well, if you have that differentiator, if you have that ability to discriminate in space, you you can see that and you can identify that something weird is going on.

Probably shouldn't be happening. So monitoring your your airways is always a good idea.
