Stay Protected: Flipper Zero And Your Credit Card


The Flipper Zero is a well-known "hacking tool" that possesses the capability to obtain Credit Card numbers by utilizing its NFC Module. Numerous YouTube videos demonstrate how effortlessly one's Credit card number can be stolen from their card while it remains in their pocket. The purpose of this post is to shed light on the possibility of such occurrences, the actual level of risk involved, and potential measures for minimizing that risk.


First, just to see if its possible we will test it with just the card:

Result: Card information is retrieved immediately.


Then, we will test to see if a high quality leather wallet creates enough of an insulator that the Flipper cannot detect the information:


Result: Card Information is quickly retrieved.

Lets see if  there is s cheap way to block the signal:

Result: Place card under a layer of basic kitchen aluminum foil 
and the signal cannot be detected.

Summary:
In today's digital age, our sensitive information is constantly at risk of being compromised. With the increased use of contactless payment methods, it is crucial to protect our credit card data from electronic pickpocketing. While special wallets and inserts designed to block RFID signals are available in the market, they often come with a hefty price tag. But fear not, there is a simple and cost-effective solution to safeguard your credit card information without purchasing these specialized products – by using aluminum foil.

Aluminum foil, commonly found in any kitchen, can serve as a makeshift RFID blocker when inserted into your wallet. The principle behind this hack is that aluminum foil is an excellent conductor of electricity and can create a Faraday cage effect. A Faraday cage blocks electromagnetic fields, including RFID signals, from penetrating and accessing your credit card information.

To implement this method, follow these easy steps:

1. Cut a sheet of aluminum foil slightly larger than your credit cards.
2. Fold the aluminum foil in half to double its thickness.
3. Slide the folded aluminum foil into a card slot in your wallet. Make sure it covers the entirety of the slot without protruding too much, as this may affect the wallet's functionality.

By taking this simple step, you are adding an extra layer of protection to your credit cards while on the go. The aluminum foil acts as a barrier, preventing the radio waves emitted by RFID readers from communicating with your card's embedded chip. Hence, potential thieves cannot skim your credit card information without physical contact.

It is important to note that while aluminum foil is an effective and accessible option for RFID protection, it may not be as durable or long-lasting as specially designed RFID-blocking wallets or inserts. Over time, the foil may wear out or become damaged, reducing its effectiveness. Therefore, it is advisable to periodically replace the aluminum foil to ensure enhanced security.

In conclusion, protecting your credit card information from unauthorized access doesn't necessarily require purchasing expensive wallets or inserts. With a simple sheet of aluminum foil, you can create a portable and cost-effective RFID-blocking solution. So, gather your materials, safeguard your wallet, and enjoy peace of mind knowing that your sensitive data is shielded from electronic pickpocketing.

Internal VPN

 To tighten up home network, and to test,  I recently made a Wireguard server behind the Sophos firewall. My Sophos Firewall is built on an old PC and I have Proxmox on a little mini PC.  The ProxMox server is setup for various services like a Unifi Controller, FreePBX, Wazuh, and most recently a Wireguard server. Essentially, a client at work mentioned that they wanted "everyone to be on a VPN" and a friend was complaining about their VPN not working when they went to the office.  Everyone at the shop mocked the idea and said it would not work....   After building this setup with a Wireguard server and setting up some special rules on the firewall to allow VPN access across VLANS, I am convinced this is the best way to segment a network.  First you can VLAN everything separating various resources but then to limit access within those VLANS is easiest with the Internal VPN server.

 Too Much to talk about: Smart TVs are using the speaker as a microphone- they dont actually turn off when you hit the power button (who would have guessed any of that?  hahahha)....   did an Geolocation ban on my network... why are the "bad countries" always hitting my network?   data has been compromised so many times most people don't even care...   Froze my my credit with the 3 agencies a year or so back...  I would suggest you do it too

Physical Security/Automation

 Fun little project. I had some of these RCWL-0516 boards laying around and a Raspberry Pi Pico so I started to wonder if I could make a motion sensor toy that would turn the lights on as i needed in my little workspace in the basement. Super easy cute python project: basically set it up to sense motion, and close a relay that turns on the LED light.    When you walk in the room the RCWL-0516 senses via microwave that there is motion, tells the Pico and the Pico sends a signal to the relay to close.   The relay will remained closed for 10 seconds after the motion is no longer detected. I am not sure how I am going to use this.... maybe a logging of detected motion and alerts?   IDK yet.
