The Security-Engineering Convergence (Edition 1.1) by Peter J. Hillier is a free, CC BY 4.0 technical book on Systems Security Engineering (SSE) as the security specialty within systems engineering. It runs from mission needs and loss scenarios through requirements, secure architecture, cyber resilience, verification and validation, acquisition, assurance cases, operations and retirement. Later chapters cover supply-chain assurance, legacy and cloud-dependent systems, systems-of-systems, and AI and autonomy. It ships as PDF, EPUB and a companion ZIP of worksheets, worked cases and standards crosswalks. It argues that meeting compliance controls is not the same as engineering evidence for mission outcomes.

Explainer on how Unix-like filesystems enforce security through owner/group/other permissions, inodes, hard links, directory execute-bit semantics, the sticky bit, and APFS copy-on-write snapshots. It ties these to real risks: 777 permissions exposing PII, world-readable config files leaking database credentials, world-writable directories allowing script replacement, and permission misconfigurations enabling privilege escalation. It recommends least privilege, ACLs, and regular entitlement reviews.

Snyk explains AI pentesting as an orchestrated system — a reasoning model that plans reconnaissance/exploitation, deterministic DAST tooling for known vulnerability classes, an independent validator model that confirms exploitability, and context from existing scanner findings — designed to catch context-dependent flaws like BOLA/IDOR, cross-tenant leakage, and chained business-logic exploits that signature-based scanners miss. It cites concrete reliability data (frontier models solving only ~26% of hard system-exploitation benchmark tasks, ~30% hallucinated findings without independent validation, 210% YoY growth in valid AI-generated HackerOne reports and 540% growth in prompt-injection reports) and positions Snyk's Evo Continuous Offensive Security product against these evaluation criteria. It also references a RAND 2026 study on low-cost CTF-solving coding agents, Anthropic/Mozilla open-source vulnerability discovery work, and Google GTIG's report of the first in-the-wild AI-assisted zero-day.

Bug Bounty Lab101 is a workspace that structures the real HackerOne bug bounty workflow: document program scope, run scope-gated recon/vuln scanning via bugbounty-hunter.sh (backed by a 400+ tool arsenal spanning recon, DNS enumeration, web scanning, exploitation, and cloud/subdomain-takeover checks), then produce a triage-ready H1 report with Hacktivity dedup checks. It also integrates T3MP3ST, a separate multi-agent offensive framework that connects local AI coding agents (Claude Code, Codex) to automate target investigation, and ships a legacy-vm-practice lab (DVWA/Metasploitable-style) for safe skill-building outside real program scope.

Huntress explains how initial access brokers (IABs) operate as specialized cybercriminals who breach organizations, verify and price the foothold, then sell it to ransomware crews, BEC actors, or data thieves via dark web marketplaces. It walks through common IAB entry vectors — infostealer credential theft, exposed RDP/VPN abuse, and AI-assisted phishing (citing a Huntress EvilTokens lure example) — and includes a real SOC case where a brute-forced RDP server led to tradecraft linked to a ransomware ecosystem. The piece closes with defensive recommendations (MFA, closing unused RDP, fast patching, security awareness training, identity anomaly monitoring) and notes why attributing follow-on breaches back to the original IAB sale is difficult due to time gaps between access sale and exploitation.

LLMVault is a self-hosted, deliberately-vulnerable training range modeled on WebGoat but for LLM applications, covering 25 labs across the OWASP Top 10 for LLM Applications (2025) - prompt injection, jailbreaking, data/model poisoning, agent exploitation, model extraction, and insecure downstream output handling. It ships two modes: a scored Play Mode with scripted assistants for repeatable flag capture, and an unscripted Live Mode that points the same attacks at a real local Ollama model (qwen2.5:3b-instruct) with a freshly minted per-session secret, requiring the player to actually talk the model into leaking it. Each lab pairs the attack with a written defense explanation, and an expert tier is shipped AES/Fernet-encrypted and unlocked manually by the maintainer.

Each challenge maps to a distinct AI security technique (prompt injection, adversarial examples, model/data poisoning, MCP tool abuse, membership inference) and offers a free certification on completion.
