hey, i'm Shobhana ๐Ÿ‘‹

AI + Cybersecurity โ€ข VoIP, malware, DNS, OSINT & a bit of cryptanalysis chaos


  • ๐Ÿ”ญ Focus areas: AI for Security, VoIP fraud, malware classification, DNS anomaly detection, OSINT tooling, neural cryptanalysis
  • ๐Ÿ“‚ Projects: 6+ security dashboards / consoles (VoIP, malware, DNS, OSINT, study assistant, second brain)
  • ๐Ÿงช Research: CNN-based bit prediction & neural differential cryptanalysis on lightweight block ciphers
  • ๐Ÿ’ป Comfort zone: *Python โ€ข ML backends โ€ข Flask โ€ข Azure Services *
  • ๐Ÿ›ก Security themes: VoIP | DNS | OSINT | threat intelligence

๐Ÿง  About me

  • ๐ŸŽ“ 3rd-year B.Tech in Computer Science (Cyber Security) @ Amrita Vishwa Vidyapeetham (CGPA: 9.12/10)
  • ๐ŸŽ“ Diploma in Data Science & Programming @ IIT Madras (Online)
  • ๐Ÿ” Into VoIP security, malware analysis, DNS anomaly detection, OSINT, and lightweight block cipher cryptanalysis
  • ๐Ÿค– Building ML-driven security systems: CNNs for bit prediction, neural distinguishers, anomaly detectors
  • ๐Ÿ›  Currently: IPTIF AGNI UG Fellow @ IIT Palakkad, working on CNN-based bit prediction on SPECK32/64

๐Ÿ›ก What I work on

  • ๐Ÿ“ž EchoShield โ€“ VoIP Security & Intelligence Dashboard

    • Dashboard for SIP/RTP traffic, speech recognition, speaker diarization, spoof detection, and spam IP tracking for real-time call risk scoring.
  • ๐Ÿงฌ Malware Classification via Assembly Instructions โ€“ Analyst Console

    • Web console to upload samples, run opcode/instโ€“based ML classification, and view SHAP-driven explanations for malware family decisions.
  • ๐ŸŒ Real-time DNS Anomaly Detection โ€“ Network Monitoring Dashboard

    • Live DNS monitoring dashboard using Scapy sniffing, entropy/structure features, and Isolation Forest to surface suspected DGA/tunneling activity.
  • ๐Ÿ” CALLGraph OSINT โ€“ Incident Investigation Console

    • Investigation dashboard that correlates SIP logs, PCAPs, and IP/domain intel APIs into a single triage view for analysts.
  • ๐Ÿ“š EduBotAI+ โ€“ Study Assistant Dashboard on Azure

    • Web interface on Azure where students can chat with an AI tutor, manage notes, and query course material using LLMs and vector search.
  • ๐Ÿง  SecondBrain โ€“ Developer Knowledge Base Dashboard

    • Personal โ€œsecond brainโ€ dashboard built with FastAPI and Supabase for QA, embedding search, similarity lookup, and chatbot-style exploration of notes and docs.

(Some repos are private; ping me on LinkedIn if you want to talk about the internals.)
