| description | Cryptanalysis techniques — lattice attacks, padding oracles, weak-RNG exploitation, signature forgery, secret-sharing recovery. |
Practical cryptanalysis for CTF and pentest engagements: identifying when a cryptographic primitive's structure (custom hash, partial leaks, related primes, bad RNG, weak modes) admits a faster-than-brute-force solver, then implementing that solver in pure Python where possible. Covers RSA-style algebraic factoring, lattice/AGCD recovery, GF(2) linear collapse of "complicated-looking" custom ciphers, smooth-order DLP, differential fault attacks, and Shamir-style secret-sharing recovery over non-prime moduli. Always read source first to detect linearity/algebraic structure before reaching for SageMath or symbolic solvers.
p = a·r + b, phi(n) perfect square, multi-prime hint files, common factors).Authentication security testing - auth bypass, JWT attacks, OAuth flaws, password attacks, 2FA bypass, CAPTCHA bypass, and bot detection evasion.
AV/EDR evasion and detection bypass — AMSI, ETW, API unhooking, process injection, AppLocker bypass, LOLBins, shellcode obfuscation.
Microsoft Exchange and SharePoint attack techniques — enumeration, ProxyLogon/ProxyShell/ProxyToken exploitation, mailbox access, SharePoint file exfiltration.
System exploitation testing - Active Directory attacks, privilege escalation (Linux/Windows), and exploit development.
Internal network pivoting and traffic tunneling — FRP, Chisel, Ligolo-ng, SSH, ReGeorg, DNS tunneling, EarthWorm, Ngrok.
Offensive AI security testing and exploitation framework. Systematically tests LLM applications for OWASP Top 10 vulnerabilities including prompt injection, model extraction, data poisoning, and supply chain attacks. Integrates with pentest workflows to discover and exploit AI-specific threats.
