Kubernetes Cloud-Native Platform & OpenStack Private Cloud

QEMU / KVM Virtual Machines & VirtIO Memory Ballooning

Consolidated Enterprise Virtualization on Node 1: All microservices and utility containers (CT 100–174) are unified on Node 1 (x86_64). Active enterprise VMs (VM 200–209) leverage VirtIO dynamic memory ballooning, while consolidated containers (CT 115–174) are configured with onboot: 0 for zero-overhead on-demand activation without consuming baseline RAM.

Host Memory Tuning: ZRAM / ZSWAP Fast RAM Compression

Compression Algorithm: Ultra-fast lz4 with < 1% CPU overhead.
Node 1 (x86_64) ZRAM: /dev/zram0 (6.0 GB RAM compressed swap, priority 100, vm.swappiness = 60, vm.vfs_cache_pressure = 50).
NVMe Lifespan Protection: High-frequency memory pages are compressed directly in RAM before touching NVMe storage, eliminating SSD wear and IO blocking.

Zero-Trust Security & Enterprise Test Environment

HashiCorp Vault / OpenBao:

Centralized secret management with zero .env files stored on local disks.
Automated dynamic token generation and ephemeral credential injection for Terraform, Ansible, and Woodpecker CI.

WireGuard Kernel Module on OPNsense with Automated Key Rotation:

Zero-downtime periodic rotation of Curve25519 cryptographic keypairs and pre-shared keys (PSK) via Ansible and cron.

Mutual TLS (mTLS) Inter-Service Communication:

Mandatory cryptographic client-certificate verification between ingress gateways and critical backend services in VLAN 20.

Canary Honeytokens & Directory Decoys:

Deceptive decoy files (passwords.csv, aws_keys.env, id_rsa_backup) placed in DMZ containers and SMB shares that trigger instant Telegram/ntfy webhooks upon access.

RenovateBot On-Premise GitOps Automation:

Continuous dependency scanning engine inspecting internal Gitea repositories and filing automated Pull Requests for new Docker images and Terraform modules.

Split-Horizon DNS Schema

External Resolution: Public domain records hosted on Cloudflare DNS point exclusively to protected VPS reverse proxy endpoints.
Internal Resolution: OPNsense Unbound DNS and AdGuard Home sinkholes resolve *.homelab.local directly to internal RFC1918 IPs (192.168.1.134), bypassing external bandwidth entirely.

10. Infrastructure as Code (Terraform & Ansible)

All infrastructure is provisioned declaratively using Terraform with the bpg/proxmox provider.

terraform/
├── main.tf                    # Root composition
├── providers.tf               # Proxmox VE provider & Remote S3 backend

    └── proxmox_vm/            # Reusable QEMU VM module

Centralized & Encrypted Remote State with DynamoDB Locking

To prevent race conditions during concurrent CI/CD executions and guarantee enterprise reproducibility, Terraform state is stored on an internal MinIO S3 bucket (CT 161) with AES-256 encryption and state locking:

terraform {
  backend "s3" {
    bucket                      = "terraform-state"
    key                         = "infrastructure/terraform.tfstate"
    region                      = "us-east-1"
    endpoint                    = "http://192.168.1.161:9000" # MinIO CT 161
    dynamodb_endpoint           = "http://192.168.1.161:9000" # Lock table
    dynamodb_table              = "terraform-locks"
    encrypt                     = true
    skip_credentials_validation = true
    skip_metadata_api_check     = true
    skip_region_validation      = true
    use_path_style              = true
  }
}

Policy-as-Code Guardrails (OPA & Conftest)

All Terraform declarations and Kubernetes manifests undergo mandatory pre-flight policy evaluation via Open Policy Agent (conftest):

Rootless Containment: Blocs any workload with runAsNonRoot: false or runAsUser: 0 (policy/kubernetes/security.rego).
Immutable Version Pinning: Forbids mutable tags (:latest) or untagged images.
Network Isolation: Prohibits unauthorized hostPort, hostNetwork: true, or host namespace leaks.

12.1 Real-World Digital Forensics & Threat Investigations (`cyber/`)

The cyber/ directory contains four end-to-end investigative case studies into active cybercrime campaigns, reverse engineered using the Datacenter's forensic sandbox tooling:

1. `task-scam-infrastructure-analysis/`

Threat Classification: Cybercrime Infrastructure, Leaky REST APIs, Crypto Money Laundering.
Incident Summary: In-depth anatomical breakdown of fraudulent "task-farming" platforms operated by organized cybercrime syndicates targeting mobile users through Telegram funnels.
Technical Exploitation & Findings:
- Exposed Backend APIs: Reverse engineering unauthenticated administrative endpoints (/api/v1/user/task, /api/admin/recharge) that leaked internal server architecture, agent referral trees, and database schemas.
- SQL Injection (SQLi) Discovery: Identified severe vulnerabilities in backend transaction endpoints allowing full parameter extraction and administrative bypass.
- Cryptocurrency Money Laundering Flow: Traced illicit USDT deposits on the TRC-20 (Tron) network across multi-hop mixing structures into centralized exchange consolidation hot wallets.
- UI Manipulation: Documented client-side JavaScript trickery that dynamically fabricated fake trading balances and simulated VIP commission payouts.
Repository Deliverables: Full case study, API exposure audit, SQLi proof of concept, OSINT infrastructure mapping, and Docker Compose test fixture.

2. `revolut-vishing-forensics/`

Threat Classification: Voice Phishing (Vishing), International SIP Telephony Fraud, 3D Secure Bypass.
Incident Summary: Complete forensic reconstruction of an advanced social engineering phone attack where threat actors spoofed official European banking support numbers to intercept real-time SMS one-time passwords (OTP).
Technical Exploitation & Findings:
- Caller ID Spoofing via International SIP Trunks: Dissected how rogue VoIP softswitches manipulate the SIP From: and P-Asserted-Identity headers to present legitimate bank caller IDs on victim smartphones.
- Real-Time 3DS Intercept: Documented step-by-step social engineering call flows engineered to induce panic, prompting victims to authorize pending credit card charges while believing they were canceling a fraud event.
- PCAP & Call Flow Analysis: Extracted session initiation protocol packets (INVITE, 180 Ringing, 200 OK, ACK, BYE), analyzed SDP audio codec negotiation (G.711u / PCMU), and mapped caller User-Agent signatures.
- Carrier Traceback & Takedown: Outlined the administrative and telecommunication subpoena processes used to isolate upstream rogue carriers.
Repository Deliverables: Complete incident timeline, technical analysis, carrier response and takedown documentation, formal regulatory report, and simulated VoIP call-flow reproduction lab.

3. `tiktok-mrr-scam-infrastructure/`

Threat Classification: Monthly Recurring Revenue (MRR) Deception, Viral Social Funnels, Payment Gateway Abuse.
Incident Summary: Investigation of automated social media ad networks promoting misleading software utilities and "AI tools" that enroll unsuspecting users into predatory recurring weekly and monthly subscription charges.
Technical Exploitation & Findings:
- Bot Cloaking & User Fingerprinting: Unpacked client-side JavaScript fingerprinting scripts designed to detect and serve benign, compliant pages to TikTok/Meta ad review crawlers while serving predatory landing pages to organic mobile users.
- Dark Pattern Payment Redirection: Analyzed multi-stage redirect chains masking merchant category codes (MCCs) to bypass payment processor risk scoring.
- Chargeback Avoidance Tactics: Identified how scammers artificially delay initial recurring billing cycles to exceed consumer dispute windows and maintain merchant acquiring accounts.
Repository Deliverables: Comprehensive prevention guide, payment gateway abuse analysis, funnel traffic breakdown, LLM course synthesis, and architectural case study.

4. `openid-mitm-phishing-forensics/`

Threat Classification: Browser-in-the-Middle (BitM / AitM), Steam OpenID 2.0 Credential & Session Theft.
Incident Summary: Dissection of an aggressive phishing campaign targeting gaming accounts by rendering a simulated, interactive pop-up browser window within the active HTML DOM.
Technical Exploitation & Findings:
- Synthetic Browser Canvas: Attackers drew an entirely fake, draggable Chrome browser window (complete with custom minimize/maximize controls, URL address bar, and spoofed green SSL padlock) entirely in HTML5/CSS, rendering standard URL inspection useless.
- Real-Time Session Relaying: Intercepted OpenID 2.0 authentication exchanges, harvesting steamLoginSecure cookies and session tokens while automatically passing SteamGuard mobile 2FA challenges.
- Automated Family View Lockout: Captured sessions were immediately automated via headless scripts to activate Steam Family View with an attacker-selected PIN, preventing legitimate account recovery.
Repository Deliverables: Full executive summary, technical reverse-engineering report, deobfuscated payload source, Suricata IDS detection signatures, and interactive HTML5 demonstration lab.

12.2 Proving Ground Defense Stack & Threat Intelligence Feeding

Findings from these four forensic investigations directly inform the proactive defense configurations across the Datacenter:

| Security Layer | Host / Virtual Machine | Engine & Role | Defensive Functionality | Perimeter IDS/IPS | `VM 200` (OPNsense) | Suricata 8.0.3 + CrowdSec | Drops active BitM synthetic popup URLs and blocks malicious IP lists via threat feeds. | Deception Honeynet| `VM 207` (T-Pot) | Cowrie, Dionaea, Honeytrap | Exposes decoy honeypots in isolated DMZ (`vmbr3`) to harvest live scanner payloads. | Enterprise SIEM/XDR| `CT 100` (Wazuh) | Wazuh Manager + Elastic Stack | Centralized syslog/FIM correlation across all 95 services with automated active response. | Host Zero-Trust FW | Node 1 (`192.168.1.132`)| Proxmox VE Cluster Firewall | Global DROP policy, rate-limited ICMP, SYN-flood guards, IPset bastion access control.

12.3 Security Auditing & Detection Tests (`cyber/red-team/`)

Verification scripts for container isolation and detection rules:

Container Audit (cyber/red-team/container_audit.py):
- Audits Linux capabilities (CAP_SYS_ADMIN, CAP_SYS_PTRACE, CAP_SYS_MODULE, CAP_DAC_OVERRIDE).
- Scans for mounted Docker/containerd UNIX control sockets (/var/run/docker.sock).
- Validates cgroup isolation (release_agent), host namespace leakage (hostPID, hostNetwork), and Seccomp/AppArmor enforcement.
Security Detection Tests (cyber/red-team/sec_tests.py):
- Runs controlled validation checks (T1059.004 Unix Shell, T1082 System Discovery, T1046 Network Service Discovery, T1552 Canary Token Search).
- Validates alert ingestion in Wazuh SIEM (Rule 80710) and CrowdSec portscan decisions.
Privilege Audit (cyber/red-team/priv_check.py):
- Evaluates writable system PATH directories, verifies private key permissions, and scans environment variables for plaintext secrets.

13. Local GPU AI LLM Runtime (Ollama CT 110)

Ollama is running inside container CT 110 on Proxmox Node 1 (192.168.1.110:11434), utilizing direct NVIDIA GeForce GTX 1050 Ti GPU acceleration:

19. Troubleshooting FAQ

Q: How do I resolve temporary DNS resolution errors inside LXC containers?

Ensure the container nameserver is set to the local DNS resolver (`192.168.1.1` or `192.168.1.4`) via pct set <VMID> -nameserver 192.168.1.1 and verify /etc/resolv.conf contains valid nameservers.

Q: How do I verify GPU Passthrough for Ollama inside CT 110?

Run pct exec 110 -- /usr/local/bin/ollama run qwen2.5-coder:1.5b "test" and check nvidia-smi on the Proxmox host to observe GPU compute utilization.

Q: How do I trigger an emergency snapshot restore in an isolated VLAN?

Execute the automated Disaster Recovery script: ./scripts/disaster-recovery/dr_vzdump_restore.sh proxmox /mnt/pve/backup-nfs/dump.
