  • Multi-Byte Key XOR Bruteforce

    Given nothing but the ciphertext, how can you bruteforce the key to get the plaintext? The script I wrote to solve this challenge bruteforces all possible values for the key, and works for both single-byte keys and multi-byte keys. The only requirement is that the user know a piece of the plaintext so that the…

  • Exfiltration from Air-gapped Network

    The goal of this project was to demonstrate the exfiltration of data from an air-gapped network through the utilization of emission from Ethernet cables to encode and transmit the data to be exfiltrated. To achieve this, I used a Cat 6 Ethernet cable along with an SDR to read the transmitted signals. The method I…
