An expert guide detailing the SuperScalar protocol and Bitcoin Lightning channel factories. It explains scalable onboarding mechanisms using shared UTXOs, advanced cryptographic structures like Decker-Wattenhofer trees, and MuSig2. This knowledge is vital for understanding how Bitcoin can scale significantly without requiring disruptive soft forks.

A comprehensive guide to simulating Man-in-the-Middle (MITM) attacks using industry-standard tools like Bettercap, Ettercap, and mitmproxy. This technique is strictly for authorized penetration testing environments to assess cryptographic controls, validate TLS certificate pinning, and test network defense mechanisms against ARP/DNS spoofing and sniffing.

This guide details methods for detecting and mitigating OAuth token theft and replay attacks in cloud environments, specifically targeting Microsoft Entra ID (Azure AD). It covers protection against access token theft, Primary Refresh Token (PRT) abuse, and pass-the-cookie attacks. Users can leverage Conditional Access and Token Protection features to cryptographically bind tokens to devices, significantly enhancing cloud identity security and preventing session hijacking.

Binary Authorization is a critical Google Cloud security control that enforces policy-based deployment rules. It mandates that only container images with valid cryptographic attestations (proof of successful vulnerability scanning, code reviews, etc.) can be deployed to GKE or Cloud Run. Use this guide to establish robust supply chain security and compliance controls for your cloud-native applications.

This skill details implementing a ransomware-resistant, immutable backup strategy using the restic tool. It leverages S3-compatible Object Lock (Compliance Mode) to ensure Write Once Read Many (WORM) storage, preventing deletion or modification by attackers. The process includes automated backup, cryptographic integrity verification (restic check), and scheduled restore testing, adhering to advanced security standards like 3-2-1-1-0.

This skill demonstrates how to integrate Hardware Security Modules (HSMs) using the standard PKCS#11 interface. It covers secure key generation, signing, encryption, and verification operations directly on the hardware. Ideal for security assessments, compliance audits (FIPS 140-2/3), and validating cryptographic controls using tools like python-pkcs11, AWS CloudHSM, and YubiHSM2.

A deep dive into advanced malware reverse engineering techniques. Learn how to utilize Ghidra's powerful disassembler and decompiler to analyze complex malware binaries. This guide covers identifying C2 communication protocols, extracting cryptographic routines, understanding memory injection, and analyzing low-level assembly code for core logic and evasion techniques. Essential for professional cybersecurity analysts.

A comprehensive guide for assessing the security of JSON Web Token (JWT) implementations. This toolkit details attacks against cryptographic weaknesses, including algorithm confusion (e.g., RS256 to HS256), 'none' attacks, brute-forcing HMAC secrets, and claim manipulation. Ideal for penetration testing and security audits of modern APIs and SSO systems.

Assesses organizational readiness for migrating cryptographic systems to post-quantum standards (PQC), aligning with NIST guidelines. The tool performs comprehensive cryptographic inventory scanning to identify quantum-vulnerable algorithms (RSA, ECDH, ECDSA) and evaluates the feasibility of implementing hybrid TLS configurations using standards like ML-KEM and ML-DSA. Essential for implementing crypto-agility across enterprise infrastructure.

This skill provides a comprehensive framework for validating backup reliability. It automates processes like cryptographic hash verification, running simulated restores to isolated environments, detecting silent data corruption (bit rot), and scanning for ransomware indicators. Use it before relying on backups during a major incident or ransomware attack to ensure data recoverability and compliance.

This guide details how to implement secure, keyless software signing using the Sigstore ecosystem components (Cosign, Fulcio, Rekor). It establishes cryptographic provenance for container images and binaries by binding identity via OIDC, ensuring verifiable integrity and tamper-proofing throughout the CI/CD supply chain.

A comprehensive guide for cryptanalysts detailing advanced attack vectors against RSA cryptography. This playbook covers factorization methods, small exponent exploits (e.g., Hastad Broadcast), lattice-based attacks (Wiener's, Boneh-Durfee), and methods exploiting protocol weaknesses like padding oracles. Essential for CTF challenges and authorized security assessments.
