What Your Support Chatbot Is Told Not to Say

The exposed WhatsApp support instructions are a prompt to test chatbot answers, escalation routes and publication controls.

AI supportWhatsAppPrivacy
Brief overview

A support assistant can avoid giving legal advice without hiding official options from a user. Test difficult conversations and keep access control outside prompts.

Incident response · AI agentsField note · 20 Oct 2026

An AI-Agent Incident Plan Needs a Stop Button and an Evidence Trail

A practical checklist for agent authority, protected logs, shutdown controls and verified recovery.

AI agentsIncident responseEvidence
Brief overview

NIST, NSA and CISA guidance for frontier-system training raises questions every team with autonomous workflows should rehearse: what can the agent reach, what records remain, who can halt it, and what proves recovery?

Detection engineering · WindowsDetection guide

Windows Security Events That Deserve Your Attention

A practical way to turn Windows account, group, logon, and lockout events into useful monitoring without drowning the SOC in noise.

WindowsActive DirectorySIEM
Brief overview

Start with reliable audit coverage, then add identity, asset, timing, source, and change context. The strongest detections explain what changed, why it is unusual, and what the analyst should investigate next.

Security assessment · EnterpriseField guide

Enterprise Security Assessment: A Practical Analyst’s Guide

A structured approach to scoping assessments, mapping assets and trust, testing realistic attack paths, validating exposure, and connecting technical evidence to business impact.

Security assessmentRiskThreat modelling
Brief overview

Start with the decision the assessment must support, follow services through their technology and identity dependencies, validate important findings safely, and turn the result into accountable treatment and evidence-backed closure.

Cloud security · Posture managementReading note

Cloud Security Posture Management: What I Found Useful

A practitioner reading note on CSPM: how continuous cloud inventory, configuration checks, risk context, ownership, and remediation fit together.

CSPMCloud securityMisconfiguration
Brief overview

CSPM is most useful when it becomes an operating loop—not another alert console. Start with visibility and read-only access, prioritize findings using exposure and business context, assign accountable owners, verify remediation, and measure whether risk is actually falling.

Vulnerability management · ProgrammeField guide

Vulnerability Management: Lifecycle and 30-60-90 Day Plan

A risk-based operating model for moving from asset visibility and discovery to verified remediation and governance.

Vulnerability managementRiskRemediation
Brief overview

Build a decision system around asset criticality, exposure, exploitability, accountable ownership, safe treatment, and evidence-backed closure—then mature it through a practical 30-60-90 day rollout.

Forensics · LinuxField note

Linux Process Analysis

Understanding processes, services, and cronjobs is fundamental to understanding the inner workings of Linux systems.

LinuxProcess analysisForensics
Brief overview

A practical field note on using ps, lsof, pstree, cron artefacts, and pspy to inspect running processes, trace parent-child relationships, and identify suspicious execution.

Detection · EndpointDetection guide

Hunting Suspicious PowerShell: Look Past the Process Name

Correlate script content, process ancestry, identity context, and network behaviour to separate abuse from routine administration.

PowerShellKQLEndpoint
Brief overview

A practical hunt that moves beyond binary-name alerts: inspect processed script blocks, follow the full parent chain, connect execution to outbound activity, and combine weak signals into a stronger case.

Investigation · IdentityInvestigation guide

Investigating Unexpected MFA Method Registration

A new authentication method can be routine maintenance—or an attacker-controlled route back into a compromised account.

MFAEntra IDPersistence
Brief overview

Reconstruct the authorising session, compare the event with the user’s normal baseline, correlate nearby identity changes, validate out of band, and contain the entire account when legitimacy cannot be confirmed.

Hunting · CloudHunt idea

Rare service-principal sign-ins

New source infrastructure or resource access may expose misuse of application credentials.

Service principalCloudHunting
Brief overview

Build a baseline by principal, source network, resource, and time. Investigate first-seen combinations and privilege changes.
