Let’s say I am interested in using one of Microsoft’s new computers but I have concerns over the massive amount of data, personal behavior, and whatnot being consumed by the machine. Microsoft claims that all of their AI toolings will be … Continue reading How to use one of Microsoft’s new computers without leaking information?
One of the simplest ways of keeping a computer system secure is by using an air gap — that is, never actually connecting the system to the network. This can …read more Continue reading Photoresistors Provide Air Gap Data Transfer, Slowly
Say I have this computer that I bought and followed a manual to physically remove all communicating modules on its motherboard, including Wi-Fi adapter, Bluetooth adapter, etc. Assuming physical security i.e. no one can see my screen throu… Continue reading Does physical removal of all communicating modules on the motherboard ensure complete safety, assuming physical safety?
How safe is it to transfer data using a USB drive between my air gaped pc and my regular pc? What things can be done to improve the safety of this?
I have developed an Excel spreadsheet to compare lists of SHA-512 hashes from two separate drives. One drive is the source data drive on a Windows machine. The other is a backup of that drive, connected to a Linux machine. I obtain the has… Continue reading Hash-Based Technique to Detect Ransomware Corruption on the Fly?
Good news, everyone! Security researcher [Mordechai Guri] has given us yet another reason to look askance at our computers and wonder who might be sniffing in our private doings. This …read more Continue reading Ethernet Cable Turned into Antenna to Exploit Air-Gapped Computers
I’m a developer in the cryptocurrency space, dealing with private keys (PK) linked to wallets containing money and I’m interested to see if this system I plan to use is secure or if I’m missing something. I define secure as the chance of t… Continue reading Is this hypothetical system dealing with sensitive keys secure? [closed]
