🛡 Wazuh Mastery Pack · 09 of 15 — VirusTotal & TI Integrations

A Wazuh alert that says "new file in /var/www" is OK.
A Wazuh alert that says "new file in /var/www, hash matched 47 VT vendors" is a different conversation.

This cheat sheet is the <integration> block pattern — VirusTotal for hash lookups, Slack for alerting, PagerDuty for on-call wake-ups, Shuffle for SOAR playbooks, and custom webhook for the rest.

Pro tip on VirusTotal:
👉 Free tier = 4 requests/min. Pair the integration with a tight rule_id (e.g. only FIM events under /var/www and /home), or you'll burn the quota in the first 10 minutes of any attack.

The ROI: every analyst-hour spent on triage drops, because the enrichment is already in the alert.

🛡 Wazuh Mastery Pack · 10 of 15 — Active Response

Detection without response is just expensive logging.

This cheat sheet is Wazuh's killer feature: built-in response scripts (firewall-drop, disable-account, host-deny), the <command> + <active-response> wiring in ossec.conf, and a Bash skeleton for writing your own AR script.

What you can automate today:
🔹 Block an IP for 10 minutes after 5 failed SSH attempts
🔹 Disable a Windows account that fired a credential-dumping detection
🔹 Kill a malicious process the moment FIM sees it write to a sensitive path
🔹 Null-route an IP across every Wazuh agent simultaneously

Two warnings I learned the hard way:
⚠️ Test ARs in lab. A misfire on rule 5715 (failed SSH from your own admin IP) can lock you out of your own server.
⚠️ Use timeouts. Permanent firewall rules age into accidental black holes within weeks.

🛡 Book Review: "The 2026 SOC Playbook — Analysing Incidents Through Attacker Thinking" by Izzmier Izzuddin

Just finished one of the most practical SOC references I've come across this year. 193 pages, 10 end-to-end playbooks built around real 2026 attack patterns — no marketing fluff, just operational gold.

🔹 What makes this different:

Most SOC material stops at the first alert. This one assumes the attacker is successful at every stage and forces the analyst to reconstruct the entire chain, ask the right questions, validate evidence, and complete containment, eradication and recovery. That mindset shift alone is worth the read.

🔹 The 10 playbooks cover what's actually landing in SOC queues right now:

✅ OAuth Consent Abuse & Payment Fraud
✅ AiTM Phishing, Token Replay & Ransomware Staging
✅ Cloud API Token Compromise & SaaS Exfiltration
✅ API Credential Stuffing & Business Logic Abuse
✅ RMM Tool Abuse & Ransomware Deployment Prep
✅ Business Email Compromise & Vendor Payment Manipulation
✅ Teams/OneDrive Phishing, Fileless PowerShell, HTTPS C2
✅ DNS Tunnelling & Covert Exfiltration
✅ Kerberos Abuse & Domain Escalation
✅ Insider Threat & Personal Cloud Exfiltration

Each playbook ships with: attacker thinking, MITRE ATT&CK mapping, simulated evidence, the right investigative questions, log sources, detection logic, and full response workflow.

🔹 Three lessons I'm taking back to my own work:

1️⃣ MFA success ≠ benign activity. The book hammers this — exactly the assumption that lets AiTM and consent-abuse attacks succeed.

2️⃣ Build the chain, not the alert. A single signal is one frame of a longer movie. SOC maturity = stitching frames together fast.

3️⃣ Backup tampering is the new ransomware tell. If your stack ignores backup-system telemetry, you're blind to the deadliest 5 minutes of an incident.

🛡 Wazuh Mastery Pack · 11 of 15 — Compliance & Audit

The fastest way to justify a SIEM budget: hand your auditor a clean Wazuh compliance report.

This cheat sheet is the mapping layer — PCI DSS, HIPAA, GDPR, NIST 800-53, SOC 2/TSC, GPG13, all built into Wazuh. Tag your custom rules with the relevant control IDs and the dashboards generate evidence reports automatically.

The real time-saver here: the SCA module (Security Configuration Assessment).
👉 Run CIS Benchmark scans on every agent
👉 12-hour interval is enough — don't pound the endpoint
👉 Auditors get instant, exportable evidence per host
👉 Ops gets a prioritized hardening backlog

Compliance shouldn't take three weeks of spreadsheet engineering. With SCA + tagged rules, it takes a single dashboard view.

🛡 Wazuh Mastery Pack · 12 of 15 — Detection Use Cases

Four high-fidelity rules for the attacks you will actually see — copy-paste, restart, you're detecting:

🔹 SSH brute force (5 fails / 60s, same IP) — T1110
🔹 Suspicious PowerShell (-enc, IEX, DownloadString) — T1059.001
🔹 Web shell creation in /var/www — T1505.003
🔹 Mass file modification (ransomware behavior) — T1486

Each rule pinned with frequency thresholds, source-IP grouping, MITRE tags, and alert levels that won't drown your inbox. They're not hypothetical — these are the patterns I tune in real environments.

The single biggest mistake juniors make:
👉 Building detections without a baseline.
Run them in audit mode (level 3) for a week. Watch the false-positive volume. Tune the regex and thresholds. Then promote to level 12.

🛡 Wazuh Mastery Pack · 13 of 15 — Docker & Kubernetes

Containers don't have a /var/log to watch. They have an event stream and an audit log. Wazuh handles both.

This cheat sheet is the working config:

🐳 Docker — the docker-listener wodle pulls container lifecycle events (create, start, exec, kill, network-connect) straight from the daemon socket
☸️ Kubernetes — Wazuh agent as a DaemonSet (one per node) plus parsing /var/log/kubernetes/audit/audit.log

The single most important event to alert on in any container environment:
👉 docker exec into a production container.

If a human (or attacker) is shelling into a running prod container, you want to know about it within seconds. That's a tier-1 alert in any mature container security program.

🛡 Wazuh Mastery Pack · 14 of 15 — Troubleshooting

Wazuh fails in three ways. This cheat sheet covers all three.

🔹 Agent won't connect
→ 90% of the time it's a port (1514 / 1515 blocked) or a key mismatch. nc -vz the manager from the agent. Re-key with agent-auth.

🔹 Queue saturated ("queue is full" in ossec.log)
→ bump <queue_size> in the <remote> block AND analysisd.event_threads in internal_options.conf. The default queue is too small for any real workload.

🔹 Cluster won't sync
→ all nodes need the same KEY, port 1516 open between them, identical Wazuh versions. cluster.log on the master tells you which one is broken.

The one habit that prevents most incidents:
👉 Before opening a ticket — grep -E 'ERROR|WARN' /var/ossec/logs/ossec.log
You'll find the answer 80% of the time.

🚨 Threat Hunting is no longer optional — it’s a core capability for every modern SOC.
Recently reviewed the Threat Hunting Playbook by RANK Software, a practical guide focused on building a proactive security posture and identifying attacker activity before major damage happens.
📘 What makes this guide valuable is its strong focus on real Indicators of Compromise (IOCs), attacker behavior, and operational hunting scenarios instead of just theoretical concepts.
The playbook covers practical hunting indicators such as:

🔹 Unusual Outbound Network Traffic
🔹 DNS Request Anomalies
🔹 Suspicious Registry Changes
🔹 Privileged Account Abuse
🔹 Lateral Movement Detection
🔹 RDP & RPC Activity
🔹 Event Log Clearing
🔹 Defense Evasion Techniques
🔹 Suspicious cmd.exe & reg.exe Activity

💡 One of the strongest sections of the guide is the inclusion of MITRE ATT&CK-aligned hunting scenarios with practical SQL-based detections for SOC analysts and threat hunters.
It also reinforces an important mindset:
🛡 Security is no longer just perimeter defense. Modern defenders must actively hunt for abnormal behavior inside the environment before attackers achieve their objectives.
👏 Huge thanks to the creators of this playbook for sharing such practical and educational content with the cybersecurity community.

🛡 Wazuh Mastery Pack · 15 of 15 — Wazuh vs Other SIEMs

The honest take, after operating most of them in production:

✅ Where Wazuh wins:
• No license cap — ingest as much as you want
• Built-in EDR (FIM, SCA, Active Response, rootkit checks)
• Compliance mappings out of the box
• Lightweight agents, multi-OS, easy enrollment

⚠️ Where Wazuh struggles:
• No native UEBA / ML-driven anomaly detection
• OpenSearch-based, slower than Splunk's SPL
• Dashboards less polished than commercial tools
• Community-driven support (paid tier exists)

The decision tree I actually use:

🔹 Tight budget + need SIEM + EDR + compliance → Wazuh, every time
🔹 Big budget + need ML / UEBA / fast search → Splunk
🔹 Need flexibility above all, willing to DIY → ELK
🔹 Already have OSSEC → migrate to Wazuh today

Wazuh isn't the best at any single thing. It's the best free SIEM/XDR that ships with everything in one box. Pair it with good engineering, and you outperform stacks that cost 50× more.

That's a wrap on the 15-part series. Thanks for reading along — and to everyone who commented, shared, or DM'd me with feedback: it kept me writing.

🔴 Active Directory is still one of the most targeted attack surfaces in enterprise environments.

I recently explored a comprehensive walkthrough on performing Active Directory penetration testing using BloodyAD — a powerful Linux-based tool for interacting with AD through LDAP and SAMR.

The document demonstrates how common AD misconfigurations can quickly lead to full domain compromise through techniques such as:

✅ AD Enumeration
✅ Kerberoasting & AS-REP Roasting
✅ DCSync Attacks
✅ ACL Abuse & GenericAll Exploitation
✅ Resource-Based Constrained Delegation (RBCD)
✅ Shadow Credentials Attack
✅ LAPS Password Extraction
✅ LDAP Enumeration & Privilege Escalation

What makes this especially valuable is the defensive perspective:
every attack path is paired with detection opportunities and hardening recommendations.

Key takeaway:
Most AD compromises happen because of misconfigurations, excessive privileges, weak monitoring, and poor segmentation — not “advanced malware.”

For Red Teamers, SOC Analysts, Blue Teams, and AD Administrators, understanding these attack chains is critical for building stronger defenses.

📌 Offensive knowledge builds defensive strength.

📊 Stanford just dropped the AI Index Report 2026 — here's what stood out to me.
The ninth edition of Stanford HAI's annual report is out (400+ pages), and the through-line is sharp: AI is scaling faster than the systems built to govern, evaluate, and absorb it. A few numbers worth sitting with 👇
🔹 Capability isn't plateauing — it's accelerating. On SWE-bench Verified, model performance jumped from 60% to nearly 100% of the human baseline in a single year. Frontier models now meet or beat human baselines on PhD-level science and competition math.
🔹 The US–China model gap has effectively closed. The two have traded the lead repeatedly since early 2025; as of March 2026 the top US model leads by just 2.7%. South Korea quietly leads the world in AI patents per capita.
🔹 The "jagged frontier" is real. A model can win IMO gold — yet read an analog clock correctly only ~50% of the time. AI agents leapt to ~66% task success on real-computer benchmarks but still fail roughly 1 in 3 attempts.
🔹 Adoption broke records. Generative AI hit 53% population-level adoption within three years — faster than the PC or the internet. Organizational adoption reached 88%, and 4 in 5 university students now use it.
🔹 Responsible AI is lagging. Safety benchmarks aren't keeping pace, and reported AI incidents are rising sharply.
🔹 The footprint is growing too. Data-center power capacity hit ~29.6 GW — comparable to New York State at peak demand.
🔹 The labor signal is subtle but important. Productivity gains of 14–26% are showing up in support and software roles — the same fields where entry-level employment is starting to soften.
My takeaway: 2025 was the year AI arrived. 2026 is the year we find out whether our governance, evaluation methods, and institutions can actually keep up. The capability curve is steep — the readiness curve isn't.
Worth a read for anyone in tech, policy, or security. 📑

📊 "You can measure anything — even cybersecurity risk."
That's the core argument of How to Measure Anything in Cybersecurity Risk by Douglas Hubbard & Richard Seiersen, and it challenges how most of us think about risk.
The uncomfortable truth the book opens with: the risk matrix — those red/amber/green "High / Medium / Low" heatmaps we all use — often adds noise, not clarity. Vague labels feel rigorous but hide the very uncertainty they're meant to manage.
The authors make the case for something better 👇
🔹 Replace ordinal scales with real quantities. Swap "High likelihood" for an actual probability and a dollar range of impact.
🔹 Calibrate your experts. Most people are overconfident. With training, analysts can give estimates that are honest about what they don't know.
🔹 Start simple. You don't need perfect data — a basic quantitative model (Monte Carlo + a few calibrated ranges) beats a color-coded chart almost immediately.
🔹 Reduce uncertainty with Bayesian thinking. Even sparse data can update and sharpen your risk estimates.
🔹 Measurement isn't about certainty — it's about reducing uncertainty enough to make better decisions.
My takeaway: in security we obsess over tools and detection, but we rarely question how we quantify the risks driving those decisions. This book is a strong nudge to treat risk like the measurable, decision-relevant thing it actually is.
A must-read for anyone in SOC, GRC, or security leadership. 📑
