CyberDudeBivash & India’s Cybersecurity Initiatives Founder’s Briefing + Technical Playbook (13-08-2025)

Executive summary

India’s digital economy, MSME backbone, and public services are scaling faster than most organizations’ security maturity. CyberDudeBivash is building a defender-first stack—news, tooling, training, and incident playbooks—so Indian teams can detect earlier, respond faster, and recover safer. This article outlines our initiatives, the technical architecture behind our tools, and how Indian businesses can adopt them with minimal friction.

Our mission (India-first)

  1. Shrink attacker dwell time across Indian SMEs, startups, BFSI, gov/edu, and healthcare.
  2. Operationalize Zero Trust with pragmatic controls that teams can actually run.
  3. Democratize threat intel through daily updates, free guides, and community workshops.
  4. Automate the boring, accelerate the critical using AI agents that are auditable and safe.

Programs & initiatives

1) Daily Threat Intel & Alerts (CyberDudeBivash ThreatWire)

  • What you get: 12–24h summaries, active CVEs affecting Indian orgs, IOCs, short “do-now” patches/mitigations.
  • Delivery: Blog, LinkedIn, and newsletter.
  • SOC-ready: Each alert ships with hunt queries, Sigma rules, and response checklists (where applicable).

2) Blue-Team Toolkit (free & paid)

  • Rapid Playbooks: Ransomware isolation, SaaS account takeover, BEC, web-shell containment.
  • “SOC-in-a-Box” for MSMEs: A curated set of EDR + patch + backup + email security templates that work on low budgets.
  • India compliance notes: Mapped actions to CERT-In’s rapid reporting (6-hour notification) and log retention (180 days), plus DPDP Act data-handling hints (data minimization, purpose limitation, breach comms).

3) Live Workshops & Masterclasses

  • Hands-on sessions for founders, admins, and blue-teamers (cloud hardening, IR drills, phishing defense, AI security).
  • Event feed posts include copy-paste commands, screenshots, and checklists so teams can implement while watching.

Product spotlight (technical breakdowns)

A) SessionShield — defeating Evilginx-style session theft

Goal: Stop cookie/session hijack—even when an attacker steals a token via reverse proxy phishing.

Deployments: Windows, Linux, and Browser (extension + native helper).

Architecture (high level):

  • Session Binding: We bind session tokens to a rotating device key + TPM attestation or WebAuthn hardware signal.
  • Contextual Signals: IP reputation, TLS JA3/JA4 fingerprint drift, geo-velocity, user-agent entropy, and “out-of-band challenge” success rate.
  • Policy Engine: If a session shows proxy fingerprints (mTLS anomalies, misaligned TLS cipher-suite, hop count oddities) → step-up auth and invalidate old token.
  • API layer: REST endpoints for SIEM/IdP: /assert, /revoke, /risk-score, /evidence.
  • Dev stack: Python/Go backend, browser extension (MV3) with native messaging; SQLite/SQLite-WAL local cache; gRPC to agent where available.

Detection examples (defensive):

  • Token replay from new ASN + identical UA hash but altered TLS FP → score↑, trigger WebAuthn prompt.
  • Cookie used from residential proxy ASN with fresh TLS session per request → strong likelihood of Evilginx tooling.

Privacy & safety: Only minimal pseudonymous telemetry; admins can disable any signal; no PII exfiltration.

B) PhishRadar AI — LLM-assisted phishing detection for India

Pipeline:

  1. Ingestion: MS Graph/IMAP connectors pull samples; optional Google Workspace API.
  2. Authenticity checks: SPF/DKIM/DMARC, BIMI, ARC; attachment MIME sanity; URL unshortening + passive DNS.
  3. Feature extraction:
    • Header graph: Path irregularity, timezone skew vs. claimed geo.
    • Text/NLP: Intent, urgency, financial lure, brand spoofing; entity consistency (sender vs. signature vs. domain WHOIS age).
    • Vision (optional): Logo misuse & page similarity (perceptual hashes).
  4. Models:
    • Heuristics baseline → fast blocklist.
    • Small local LLM → explainable classification; prompt templates constrain hallucination.
    • Ensemble score → 0–100 with thresholds for quarantine, review, deliver.
  5. Outputs:
    • Analyst card (verdict + “why” with evidence links).
    • Auto-response to users with safe-preview of suspicious links (no live click).
    • STIX 2.1 objects for sharing; TAXII push to ISACs/partners.

Why this matters in India: Many attacks ride UPI, GST, KYC, and bank-update pretexts. PhishRadar includes vernacular-aware features (Hindi/Odia/Bengali code-mixed text cues) and brand-kit templates common to Indian banks/PSUs.

C) CyberDudeBivash Threat Analyser App — analyst workstation

Target user: Solo IT admin to mid-size SOC.

Core modules:

  • Threat Lookups: VT/URLhaus/MISP; Shodan/Censys for exposed services; ASN/IP context.
  • Malware Triage: Static PE/ELF metadata, YARA scanning, PE-safety triage (no live detonation by default).
  • Hunting Helpers: Sigma → backend SIEM dialects (Elastic/KQL, Sentinel, Splunk SPL).
  • Casework: Evidence locker with integrity hashes; chain-of-custody notes.
  • GUI: Tkinter/PyQt; REST API for headless automation.

Performance: Async workers; cached lookups; throttled API calls; optional GPU for heavy vision models.

Zero Trust for Indian orgs (step-by-step)

  1. Identity as the new perimeter
    • Enforce MFA (prefer FIDO2/WebAuthn), conditional access (risk, device health).
    • Just-in-Time admin roles; strong break-glass with vault + hardware token.
  2. Endpoint hardening
    • EDR everywhere, device encryption, USB control; application allow-listing for finance & ops teams.
    • Patch cadence + ringed deployment; test on pilot groups before org-wide rollout.
  3. Network and SaaS
    • TLS inspection boundary (respecting privacy/PII policies), DNS filtering, egress allow-lists for production.
    • SaaS posture: disable legacy auth; review OAuth app sprawl; rotate stale tokens.
  4. Data
    • Classify critical data (customer, IP, financial); least-privilege shares; immutable backups with offline copies.
    • DLP rules for common Indian identifiers (PAN, Aadhaar masking in logs/exports).
  5. Observability
    • Centralize logs with 180-day baseline retention; alert on token misuse, privilege escalations, MFA fatigue.

Incident response playbook (condensed)

  • 1. Detect & Triage: Confirm scope; snapshot volatile data; tag case ID.
  • 2. Contain: Disable compromised accounts; isolate hosts; revoke sessions/tokens; geofencing if needed.
  • 3. Eradicate: Remove persistence (scheduled tasks, WMI, Run keys, startup folders), rotate creds, patch entry CVE.
  • 4. Recover: Clean images, staged re-enablement, restore from immutable backups.
  • 5. Report: CERT-In notification, affected user comms; legal/DPDP considerations.
  • 6. Learn: Post-incident review; control owners and deadlines.

Sector focus & use cases in India

  • MSME & Startups: “SOC-in-a-Box” + managed alerts; protect billing/UPI flows and customer PII.
  • BFSI/FinTech: SessionShield for session binding; PhishRadar for KYC/OTP lure detection; strong transaction anomaly hooks.
  • Healthcare: Ransomware isolation playbooks; DICOM/HL7 exposure scans; clinical downtime drills.
  • Edu/Gov: Email authentication rollout (DMARC p=quarantine→reject); shared device lockdown; student phishing simulations.
  • OT/Manufacturing: External surface reduction; vendor-access jump hosts; backup cold-sites.

Roadmap (next 6 months)

  • ThreatWire Hindi/Odia editions with regional lures.
  • Managed PhishRadar for small IT teams (alert → ticket → guided response).
  • India CVE Heatmap (sector/region overlays) for weekly board briefs.
  • Bug-Bounty Safe Harbor framework for responsible disclosures to Indian SMEs.
  • Partner network (MSSPs and cloud providers) for last-mile deployment.

KPIs we hold ourselves to

  • < 24h: Patch/mitigation guidance for actively exploited CVEs.
  • -40%: Reduced phishing click-through within 90 days of PhishRadar rollout.
  • T<5 min: Mean time to session revocation with SessionShield policies.
  • 100%: Incidents recorded with reproducible evidence and chain-of-custody.
