NYCT4L3/README.md

Hi, I'm NYCT4L3 πŸ‘‹

Cybersecurity student focused on offensive security and penetration testing. I learn by building, and I run all my experiments in a confined, authorized lab environment.

πŸ”§ Projects

πŸ•΅οΈ Cross-Layer Fingerprint Impersonation Detector (in development)

Detects clients that fake their identity on the network. Instead of trusting a single signal, it extracts JA4 (TLS), JA4T (TCP) and JA4H (HTTP) fingerprints from the same flow and checks whether they agree with each other. For example, a connection that looks like Chrome on Windows at the TLS layer but behaves like a Linux Python client at the TCP and HTTP layers gets flagged.

  • Flow-based analysis (an IP address is never treated as a device identity, so NAT and shared IPs are handled correctly)
  • Certificate and packet-behavior checks
  • Weighted consistency and risk scoring, with verdicts: CONSISTENT / SUSPICIOUS / FLAGGED
  • Audit logging, ground-truth labeling, and evaluation (accuracy, precision, recall, F1, confusion matrix)
  • Plain-language explanations of why a flow was flagged

A security-focused application that confirms a user is still active through regular check-ins. If they stop responding, it moves through a grace period and trusted-contact warnings, then triggers a Dead Man's Switch that releases encrypted information to chosen recipients.

  • Encrypted digital vault with controlled, conditional release
  • Lost Device Mode and Emergency Mode
  • MFA, device and session management, replay and spoofing protection
  • Audit logs and compromise detection
  • Includes a security-testing section that demonstrates attacks (IDOR, XSS, CSRF, replay and more) and their mitigations

πŸ“ Cyber Scribe

A Python tool that turns spoken lab notes into structured Markdown journal entries (voice recording, then transcription, then organized notes), so my lab work and reasoning are always documented.

🚩 CTF Challenge Development

Designed and built five OSINT, forensics and crypto challenges for CTF 26' Fall Edition, run by Cyber Infinity Riphah at Riphah International University. β†’ CTF-Challenges-2026: player files and writeups

πŸ“š What I'm studying

Networking Β· Linux Β· Python Β· Web & application security Β· Network enumeration Β· Penetration testing Β· Windows & Active Directory Β· Cryptography Β· Cloud & containers

🎯 Goals

Build a career in offensive security, develop tools that support penetration testing, and keep growing through CTFs, both playing them and building them.

πŸ§ͺ How I work

All experiments run in an isolated, authorized lab. I follow responsible, ethical practices.
