Red Team in AD
The complete red-team AD chain. Modules 8-17 in AD track covered individual techniques; this is operator playbook. Path planning Initial access (phish, web exploit, valid creds) Local recon (BloodHound from compromised host) Identify shortest path to DA Choose technique per step (Kerberoast → DCSync, or RBCD → ticket forge) Execute with OPSEC (silent EDR-evasive techniques) […]
Continuous Threat Intel Workflow
Most Indian organisations don’t have dedicated CTI teams. But you can run a 1-person / 0.5-FTE program effectively. The cadence Daily (15-30 min) — skim Twitter/X security feed; check threat-feed updates; review SIEM enrichments Weekly (2 hours) — read 2-3 vendor reports; update threat-actor watchlist; brief SOC on changes Monthly (half day) — assessment review, […]
Red Team in Cloud
Cloud red teaming is different from AD. No NT hashes; tokens. No Kerberos; OAuth/STS. Different tools, different OPSEC. The cloud kill chain Initial credential acquisition (phishing dev for AWS keys, or compromise endpoint with cached cli credentials) Discovery — what services, what permissions Privilege escalation — IAM-misconfig paths (covered Cloud Module 8-9) Lateral movement — […]
Data Exfiltration Techniques
Data exfiltration is the goal of most non-ransomware attacks. Network defenders should know patterns. Common channels HTTPS to attacker domain — most common; blends with legit traffic HTTPS to cloud storage — Dropbox, Google Drive, AWS S3 (attacker bucket); user-agents look legitimate DNS tunneling — covered Module 9 Networking ICMP tunneling — niche but possible; […]
Red Team Reporting
The report is the deliverable. A great engagement with poor reporting fails to drive change. Three audiences Executives — what could happen; what was the impact; what investment justified Security team — TTPs used, detection gaps, recommended controls Engineering / IT — specific configurations to change, code to fix Structure Executive summary (1-2 pages) Engagement […]
Red-to-Purple Handoff
One-shot red team engagement: report → file in drawer. Purple-team handoff: report → workshop → detections built. The latter is what produces lasting improvement. The handoff workshop Red team walks through engagement chronologically For each step: blue team confirms what (if any) signal fired Where signal fired but ignored — investigate why Where no signal […]
Red Team Engagement Management
Red team is high-risk consulting. A bad engagement can crash production, leak data, breach contracts. Discipline matters. Rules of Engagement (ROE) Authorized targets and out-of-scope assets Authorized techniques and prohibited (e.g., DoS, social engineering of HR) Engagement window Stop conditions Deconfliction contacts (real production incidents vs red team) Get-out-of-jail letter Communication Trusted Agent (TA) on […]
The Pyramid of Pain
Covered briefly in Blue Team Module 6. This is the deeper dive. The pyramid Hash values — recompile, hash changes IPs — rotate infrastructure Domains — register new Network/host artefacts — User-Agent, registry keys Tools — Cobalt Strike, Mimikatz TTPs — tactics, techniques, procedures Top of pyramid = harder for attacker to change. Operational implication […]
MITRE ATT&CK in Practice
MITRE ATT&CK is the de-facto common language. Operationalising it requires discipline. The structure Tactics (14) — adversary goals (Initial Access, Execution, Persistence, etc.) Techniques (~200) — how the goal is achieved Sub-techniques — specific variants Procedures — actor-specific implementation ATT&CK Navigator Free tool for visualising layers. Use cases: Coverage map — which techniques have detections […]
STIX & TAXII Standards
STIX = data format. TAXII = transport. Together: machine-readable threat intel sharing. STIX object types Indicator (the “what to look for”) Threat Actor Campaign Intrusion Set Malware Tool Attack Pattern (= ATT&CK technique) Vulnerability (= CVE) Identity (= Victim) Relationship Why structured matters Vendor PDF report → manual extraction. Vendor STIX feed → automatic ingestion […]
