KRISH

Offensive security and hardware research. I break systems to find out how they fail, then write the tools to do it again.

Based in India. I work across RF and IoT (mostly ESP32), Android reversing and rooting, and pentest tooling. My bench has two laptops, an SDR, a JTAG, a scope, and a logic analyzer. The work happens there, not in the cloud.

Currently building

  • ESP32-HARNESS: ESP32 pentest and telemetry firmware. 2.4 GHz RF work, RF24 experiments, side-channel probing.
  • OU Hunt Report: red-team engagement writeup. Six validated findings, each with a proof of concept.
  • pypentest-ai: offline LLM-driven pentest agent that runs on local models.
