Complete SQLMap Database Penetration Testing Guide by Harshit Rajpal & Aarti Singh

This PDF breaks down SQLMap from beginner to advanced level, with real-world examples, commands, and workflows that mirror what you’d do in an actual assessment.

πŸ”Ή SQL Injection Detection
– Error-based, Boolean-based, Time-based
– Identifying vulnerable parameters
– Breaking queries to trigger server errors

πŸ”Ή Database Enumeration
– Listing DBMS names
– Enumerating databases, tables, columns
– Extracting sensitive data safely

πŸ”Ή Data Extraction Techniques
– Dumping specific tables
– Full database dumps
– Hash extraction and format recognition

πŸ”Ή SQLMap Targeting Options
– -u for single URL targeting
– Attacking from log files
– Bulk attack using multiple URLs
– Using Google Dorks with SQLMap
– Running SQLMap on intercepted HTTP requests (-r option)

πŸ”Ή File System & OS Interaction
– Uploading / downloading files
– Executing system commands
– Out-of-band shells and Meterpreter sessions

Deep-Dive Drop: Dev(sec)Ops Process for Dummies πŸœβš™οΈ

Most teams ship code to production in minutes… and trust a few YAML lines not to burn the house down

In this guide, I break down how one missing security gate in a CI/CD pipeline led to a 47-minute attack and $4M+ in damageβ€”and how to redesign your processes so it never happens again.

πŸ” The 3:47 AM Incident
β€’ Step-by-step timeline from alert β†’ triage β†’ forensics β†’ root cause
β€’ How a β€œhotfix” branch, skipped scans, and an expired token led to full domain compromise

πŸ— Secure vs Insecure DevOps Patterns
β€’ Manual approval gates, shared service accounts, static tokens, no baselines
β€’ Secure alternatives: immutable workflows, environment-specific gates, anomaly detection, auto-rollback, ephemeral creds

🧩 8 Core Processes Across the SDLC
β€’ Vulnerability scanning (SAST/SCA/DAST/Cloud/IaC)
β€’ CI/CD pipeline security and workflow hardening
β€’ Infrastructure change management (Terraform / K8s / cloud)
