Post-Quantum Cryptography 101 — NIST FIPS 203, 204, 205 (ML-KEM, ML-DSA, SLH-DSA) Explained
NIST's final PQ standards orientation: ML-KEM (FIPS 203) replaces RSA/ECDH, ML-DSA (FIPS 204) replaces RSA/ECDSA signatures, SLH-DSA (FIPS 205) is the conservative hash-based alternative. Migration map and size impact.
Grover’s Algorithm — Symmetric Crypto’s New Math (Hint: AES-256 Wins)
Grover halves symmetric crypto security in bits — AES-128 weakened, AES-256 still safe. SHA-256 collision resistance halves but stays secure. Practical migration: use AES-256, SHA-384 for long-lived data. Module 4.
Shor’s Algorithm Explained — Why RSA and ECC Will Break
Shor's algorithm factorises integers and computes discrete logs in polynomial time on a quantum computer — breaking RSA and ECC. How it works at intuition level, hardware requirements, and the Mosca theorem applied. Module 3.
Why Quantum Matters for Cybersecurity — The Post-Quantum Threat in Plain English
The post-quantum threat quantified — what crypto breaks, when CRQC arrives, store-now-decrypt-later risk, Mosca theorem, and what your CISO should be telling the board today. Module 2 of the Quantum Computing track.
What is Quantum Computing — Qubits, Superposition, Entanglement (Beginner)
Quantum computing fundamentals for security practitioners — qubits, superposition, entanglement, gates, and what quantum computers can and cannot do. Module 1 of the RingSafe Quantum Computing track.
Sliver C2 Operator Guide — Implants, Transports, OPSEC, and the Detection Patterns Blue Teams Should Hunt
Sliver is the open-source post-Cobalt-Strike C2 framework — accessible to Indian red teams without licensing barriers, and the most-abused C2 after CS itself. Architecture, implant generation, transport choices, OPSEC patterns, and the defender-side hunt queries that actually catch it.
Burp Suite Pro 2026 — Five Production Bambdas and Three Custom BChecks (Paste-Ready)
Burp Bambdas (per-request JavaScript) and BChecks (YAML scanner checks) are the highest-leverage features in Burp Pro 2026. Five paste-ready Bambdas (sensitive data, JWT alg-none, parameter pollution) and three BChecks (open redirect, IDOR, CORS) for your next engagement.
Caido for Web Pentest — A Modern Alternative to Burp Suite Pro (Hands-On Walkthrough)
Caido is the first credible challenger to Burp Suite Pro — Rust-built, web UI, multi-tester collaboration. Architecture comparison, workflow-by-workflow analysis of where Caido beats Burp and where Burp still wins, and a 4-week migration plan for Indian pentest teams.
LLM Jailbreaks 2026 — Universal Suffixes, Many-Shot, Crescendo, and What Constitutional AI Actually Stops
LLM jailbreak research in 2026: GCG universal suffixes, AutoDAN, many-shot context-poisoning, Crescendo multi-turn, multimodal vision attacks. Why alignment is structurally defence-in-depth, the production controls that actually work, and a test harness for measuring your model versions.
Indirect Prompt Injection — When Documents, Emails, and Tool Outputs Become the Attacker
Indirect prompt injection lives in third-party content the model reads — documents, emails, web pages, tool outputs. Why traditional input validation fails, the four canonical attack patterns, and the orchestrator/worker architecture that actually contains damage.
