Exploring the Privacy Risks of Tire Pressure Monitoring Systems with RTL-SDR
The privacy issue is that these TPMS sensors each transmit a unique identifier, so the computer can know which tire is being measured, and not read other vehicles' sensors by mistake. As TPMS is not encrypted in any way, anyone with an RTL-SDR or other similar radio can receive and decode TPMS messages, including the unique identifier. This raises privacy concerns as this can be used to log the presence and movement of individual vehicles.

Making the Hashcracky Hashcat Rules
In this post, I am going to go over a few high-level methodologies used to create all the rules on Hashcracky.com. I started making my own rule sets several years ago, and hopefully this documents some process of the common pitfalls and concepts for others to make their own. I strongly believe in understanding the intention behind rules that are used and using that to create a strategy. Likewise, I use rules as a method to target subsets of commonly created human heuristic behavior. Using this as my primary goal, the rule sets are crafted with this in mind, and unfortunately the process is not always super clean, so this will be a guide rather than an exact method.

PowerShell for Hackers - Survival Edition - Part 4 - Flying Under the Radar
In this part, we move on to three practical pillars of Living off the Land: network reconnaissance, data exfiltration, and persistence. Together, these cover most of what is needed for real-world operations. There are, of course, far more advanced techniques that offer higher levels of stealth and sophistication, but they also require deeper expertise and are useful only in very specific situations.
