What is TLS Fingerprinting?

A conversation with Pim from Scrappey (A Software Engineer) that explains what TLS fingerprinting is and how it can be prevented.
Today I wanted to talk about something that you may not have heard of before, but is actually really important to understand - TLS fingerprinting.
TLS (Transport Layer Security) fingerprinting is essentially a way for someone to identify and track specific devices or software programs by analyzing their TLS configurations. This can include things like the specific version of TLS being used and the specific cipher suites being utilized.

Now, you might be wondering why anyone would want to do this. There are actually a few reasons. Some people might use TLS fingerprinting to track the use of certain software programs or devices, identify the specific operating system or browser someone is using, or even figure out the identity of individual users. On the flip side, TLS fingerprinting can also be used for more nefarious purposes, like targeted advertising, cyber espionage, and tracking the online activities of specific individuals.
So, what can we do to prevent TLS fingerprinting? One option is to use a tool that randomizes the TLS configurations of our devices or software programs, making it harder for attackers to identify specific configurations. Another option is to use a tool that allows us to specify our own TLS configurations, rather than relying on the default configurations of our devices or software programs.
Another way to prevent TLS fingerprinting is to use a VPN (Virtual Private Network) to encrypt all of the traffic that we send over the internet. This makes it much harder for attackers to analyze the TLS configurations of our devices or software programs, as the traffic is encrypted and cannot be easily examined.
Finally, we can also protect ourselves from TLS fingerprinting by regularly updating our devices and software programs to the latest versions. These updates often include improved security measures and fixes for vulnerabilities that could be exploited by attackers.
In short, TLS fingerprinting is a technique that can be used to identify and track specific devices and software programs, and it's important that we take steps to protect ourselves from this type of tracking. By using tools that randomize TLS configurations, using a VPN, and regularly updating our devices and software programs, we can help to protect ourselves from TLS fingerprinting and other forms of online tracking.
