This guide provides a comprehensive framework for minimizing cloud expenditure on Databricks. It covers identifying cost drivers via system billing tables, implementing cluster policies, utilizing spot instances for batch processing, right-sizing SQL warehouses, and automating the shutdown of idle development clusters. Use it when managing cloud spending or optimizing data platform usage.

This skill provides comprehensive expertise for senior database administrators to optimize and manage PostgreSQL databases at an advanced level. Use it for deep query analysis via EXPLAIN ANALYZE, implementing advanced features like JSONB indexing, configuring streaming or logical replication, and maintaining database health through VACUUM tuning and monitoring pg_stat views. Ideal for building highly available, high-performance, and resilient system architectures.

This skill provides a comprehensive guide for identifying and exploiting insecure local data storage vulnerabilities in Android and iOS applications. It covers analyzing plaintext credentials, unencrypted SQLite databases, insecure SharedPreferences, and improper keychain/keystore usage. Essential for performing robust mobile penetration testing focused on OWASP M9.

This guide details how to implement HashiCorp Vault's dynamic secrets engine. It automates the generation, lease management, and rotation of short-lived credentials for databases (e.g., PostgreSQL, MySQL), AWS IAM, and PKI certificates. This method eliminates the use of static, hardcoded secrets, enforcing zero-trust principles and meeting stringent compliance mandates like PCI-DSS.

This skill details the deployment of Privileged Access Management (PAM) for critical database systems, including Oracle, SQL Server, PostgreSQL, and MySQL. It covers essential security controls such as session proxy configuration, credential vaulting, query auditing, and enforcing least-privilege access, helping organizations meet stringent compliance and security standards.

This comprehensive guide details the deployment of HashiCorp Vault for robust, centralized secrets management in hybrid and multi-cloud environments. It covers configuring dynamic secret engines for databases (PostgreSQL) and cloud providers (AWS), integrating diverse authentication methods (OIDC, AppRole, Kubernetes), and securely delivering short-lived secrets to Kubernetes workloads via agents. The primary goal is to enforce zero-trust principles by eliminating hardcoded, long-lived credentials from application code and CI/CD pipelines.

LaZagne is an open-source post-exploitation tool utilized by red teams to harvest stored credentials from compromised endpoints. It supports Windows, Linux, and macOS, extracting passwords from browsers (Chrome, Edge), databases (MySQL, SQLite), system vaults (DPAPI, LSA), and various applications. It is crucial for privilege escalation and lateral movement during authorized security assessments.

A comprehensive guide for performing authorized security assessments on GraphQL APIs. This skill covers key areas such as endpoint discovery, schema introspection, testing for authorization flaws (BOLA/BFLA), injection vulnerabilities (SQL/NoSQL), and denial-of-service risks. Essential for penetration testers and bug bounty researchers targeting modern web applications.

A comprehensive guide for performing systematic security assessments on web applications. Following the OWASP Web Security Testing Guide (WSTG), this process identifies critical vulnerabilities such as broken authentication, authorization flaws (IDOR), SQL injection, and Cross-Site Scripting (XSS). The workflow covers reconnaissance, mapping, and advanced testing techniques using tools like Burp Suite and sqlmap, ensuring deep coverage beyond automated scanner capabilities. Ideal for pre-production security validation and compliance audits.

This skill provides comprehensive guidance on hardening and securing critical process historian servers (e.g., OSIsoft PI, Honeywell PHD) operating within Operational Technology (OT) environments. It covers best practices for network placement across the Purdue Model, implementing robust access controls, establishing secure data replication architectures through DMZs (using data diodes), preventing SQL injection, and maintaining data integrity for safety-critical and regulatory reporting purposes. It is essential for minimizing cyber risks in industrial control systems.

An expert-level playbook detailing advanced techniques for NTLM relay and authentication coercion. Covers cross-protocol attacks targeting SMB, LDAP, HTTP, and MSSQL. Includes methods like LLMNR poisoning, PetitPotam, and advanced domain privilege escalation to bypass standard authentication controls.

Implements HashiCorp Vault's dynamic secrets engine to automatically generate, lease, and rotate short-lived credentials for databases (e.g., Postgres, MySQL), AWS IAM keys, and PKI certificates. This eliminates the risk associated with storing static secrets, ensuring compliance with zero-trust principles and automating the entire secret lifecycle.
