Pipeline Orientation

This notebook documents the end-to-end ML pipeline for Project Lost Piglet 2 (LP2) — an independent cyber-intelligence study testing whether telemetry from a high-interaction SSH honeypot can be machine-scored at scale to separate human threat actors from commodity botnet automation. The hypothesis: deliberately engineered Cognitive Friction (password-protected archives, psychologically loaded filenames, non-standard logic puzzles) forces measurable decision latency that becomes the anchoring feature for behavioral classification.

The pipeline ingests raw Cowrie JSONL from a 23-day deployment (174,963 events), enriches it with geographic and SSH-client metadata, runs a three-model ensemble (Isolation Forest + HDBSCAN + Decision Tree surrogate for explainability) under EVT/KS dynamic thresholding, and terminates in an audience-specific Threat Intelligence Report. Each phase is self-contained and can be reviewed independently.

Phase Map

Phase	Module	Purpose
I	Data Ingestion & Preprocessing	Merge LP1 + LP2 archives into a unified session DataFrame
II	Enrichment & Normalization	ip-api geolocation, ASN resolution, column normalization
III-A	Classification — Isolation Forest	Session-level anomaly scoring with EVT/KS dynamic thresholding
III-B	Density Clustering — HDBSCAN	Behavioral taxonomy; ejects botnet mass as noise (-1)
III-C	Explainability — Decision Tree Surrogate	Human-readable rules behind the ensemble outputs
IV	Behavioral Assessment	MITRE tactic mapping, malware campaign analysis, LP1↔LP2 comparison
V	Keystroke & Burst Analysis	Execution velocity across taxonomy groups (human vs. bot timing signatures)
VI	HASSH Fingerprinting	SSH client identification and cross-campaign attribution
VII	TTP Mapping (MITRE ATT&CK)	Two-stage semantic classifier — TF-IDF cosine + keyword hierarchy
VIII	Session Forensics & Cognitive Friction	Dwell-time forensics on the highest-value interactive session
IX	Cross-Session Attribution	Skeleton-based clustering; LP1→LP2 infrastructure continuity
X	Threat Intelligence Report	SOC Manager tactical brief + Strategic Intelligence product

Headline Findings

• 174,963 events → 6 human-interactive sessions — greater than 99.96% noise reduction
• RedTail cryptominer campaign captured end-to-end — 6 unique payloads across 49 delivery cycles, originating from 130.12.180.51 (UK)
• LP1 → LP2 cross-node attribution — 33-day persistent botnet infrastructure identified across two independent deployments
• Top threat origins: China (56%), India (15.8%), Malaysia (6.6%)

------------------------------------------------------------------------------------------
STRATEGIC INSIGHT — COGNITIVE FRICTION ANALYSIS:
  Human/Interactive Sessions:  6 of 16,180 (0.0371%)
  Lure Feature Decision Weight: 0.00%

  FINDING: ZERO LURE FEATURE IMPORTANCE IN DECISION TREE.

  This does NOT indicate the lure methodology failed.
  With 6 confirmed human session(s) out of 16,180
  (0.0371%), lure features have effectively zero
  variance at dataset scale. The tree correctly learns to classify using
  high-variance features (burst_ratio, entropy_delta) because those
  distinguish the vast majority of sessions.

  The 7 confirmed lure interactions are analytically significant but
  statistically invisible at this sample composition.

  Lure evidence is documented through individual forensic analysis:
    → Phase VIII (Session Forensics): Confirmed human lure session timeline
    → Phase X   (TI Report):          7 confirmed lure interactions documented

  For lure features to gain meaningful decision weight, LP3 should
  target higher human actor volume (port 22 vs 2222 deployment, or
  additional persona content in more accessible filesystem locations).

  THESIS VALIDATION: If the ML classification is behaviorally correct,
  human-labeled sessions should show measurably higher median cadence
  (slower execution) than bot-labeled sessions. The table above provides
  the quantitative evidence for or against this claim.
--------------------------------------------------------------------------------
  LP2 STRATEGIC ASSESSMENT:
  → 88.4% sub-second execution confirms an environment
    dominated by highly-scripted, non-interactive botnets.
  → 8 friction-zone transitions detected across full harvest.
    Examine human-session breakdown above for lure-attributed pauses.
  → Echo Swarm single-command sessions produce zero inter-command deltas
    and are absent from this analysis by definition, not data loss.

PHASE VI: HASSH FINGERPRINTING

2026-04-12 02:01:22,486 - INFO - HASSH telemetry extracted: 24005 KEX events, 37 unique fingerprints.

================================================================================
### PHASE VI: TECHNICAL ATTRIBUTION — TOOLING PROFILE AUDIT ###
================================================================================
  Primary Client Library:    Unidentified Custom Tooling (LP2 Primary — 66.2% of traffic)
  Primary HASSH Signature:   01ca35584ad5a1b66cf6a9846b5b2821
  Dominance:                 65.0% of 24,005 KEX events
  Fingerprint Diversity:     37 unique SSH libraries detected.
  Dependency Classification: HIGH
--------------------------------------------------------------------------------
  STRATEGIC FINDING:
  → 65.0% concentration in a single unidentified SSH library
    is definitive evidence of centrally-managed botnet C2.
    Distributed botnets using compromised endpoints would exhibit
    diverse SSH client fingerprints (OpenSSH versions, PuTTY, etc.).
    A single dominant custom library indicates purpose-built
    infrastructure operating under coordinated command.

  → See Phase IX for full campaign cluster analysis.
--------------------------------------------------------------------------------
  LP1 → LP2 CROSS-DEPLOYMENT CONTINUITY CONFIRMED:
  → LP1 primary fingerprint (16443846184eafde...)
    detected in LP2 harvest: 286 session(s).
  → Same SSH client library active across both deployments
    (Feb 3-6 LP1 South Carolina → Feb 11 - Mar 5 LP2 Virginia).
  → Proves botnet infrastructure is persistent — maintained active
    operations across a 33-day window, two distinct US-east nodes.
  THESIS VALIDATION: Cross-node campaign attribution confirmed.

  FORENSIC NARRATIVE:
  HUMAN VOYEUR / INTERACTIVE THREAT — INTERACTIVE EXPLORATION:
  The session timeline shows deliberate command-by-command exploration
  consistent with human interactive behavior.
  → No explicit lure file read commands (cat, less, vi) detected.
    Actor may have navigated the filesystem interactively without
    issuing read commands that Cowrie captures in command.input logs.
  → Maximum command pause of 3.3s exceeds the 3.0s cognitive
    friction threshold — consistent with deliberate evaluation behavior
    even without command-level lure confirmation.
  → Biological variance of 1.00 confirms irregular timing
    inconsistent with any known automated SSH client behavior.

    The identical SSH client library was active during LP1 (Feb 3-6,
    South Carolina) AND LP2 (Feb 11 – Mar 5, Virginia) — a 33-day window
    spanning two distinct US-east sensor nodes.
    This proves the botnet infrastructure is persistent and geographically

  TACTICAL ASSESSMENT:
  → Reach Heatmap: Stars/Pentagons isolate industrial-scale Swarm clusters
    from bespoke noise in the lower-left quadrant.
  → Primary Infrastructure: 64-IP cluster dominates Zone II/IV.
  → Payload Polymorphism: 5 clusters show cross-IP script reuse,
    confirming centralized C2 dispatch rather than independent operators.
  → Evidence: Multiple distinct botnet operations actively rotating IPs
    while maintaining identical tactical playbooks and SSH client libraries.

  CAMPAIGN OVERVIEW───────────────────────────────────────────────────────────────────────────────
  Engagement Period:  LP1 Feb 3–6, 2025  |  LP2 Feb 11 – Mar 5, 2025 (33-day window)
  Honeypot Nodes:     Two US-East AWS instances (South Carolina + Virginia)
  Total Sessions:     25,880
  Human-Classified:   6  (interactive actors, ML-confirmed)
  Primary Origin:     China
  SSH Tooling:        6 distinct client libraries identified

  OVERALL RISK RATING─────────────────────────────────────────────────────────────────────────────
  ┌─────────────────────────────────┐
  │   RISK LEVEL:  [  CRITICAL  ]   │  ← Confirmed malware delivery + human actor
  │   CONFIDENCE:  HIGH             │  ← ML classification + VT hash confirmation
  │   PERSISTENCE: CONFIRMED        │  ← 33-day LP1→LP2 cross-node continuity
  └─────────────────────────────────┘

  STRATEGIC KEY FINDINGS──────────────────────────────────────────────────────────────────────────

  [FINDING 1]  PERSISTENT BOTNET INFRASTRUCTURE — LP1→LP2 CONTINUITY
  The dominant SSH client fingerprint (HASSH: 16443846...184e) observed in LP1
  (South Carolina, Feb 3–6) reappeared in LP2 (Virginia, Feb 11 – Mar 5).
  Same custom tooling, different hosting node, 33-day sustained operation.
  IMPLICATION: This is not opportunistic scanning. This is a managed,
  geographically distributed botnet with persistent C2 infrastructure.

  [FINDING 2]  REDTAIL MULTI-ARCHITECTURE MALWARE CAMPAIGN
  Source IP 130.12.180.51 (United Kingdom) executed 49 delivery cycles
  deploying 6 unique payloads targeting 6 architectures
  (arm7, arm8, i686, x86_64). Consistent with botnet infrastructure build-out.
  VirusTotal: API key not configured — set VIRUSTOTAL_API_KEY in Phase IV
  to enable live hash confirmation. Browse URLs generated for manual review.
  IMPLICATION: Active cryptomining/botnet recruitment campaign with
  multi-architecture targeting indicates professional threat actor.

  [FINDING 3]  HUMAN ACTOR — JIM HARRIS PERSONA ENGAGED
  Timing-based cognitive friction confirmed (Phase VIII >3s pauses).
  Command-level file access not confirmed in this run.
  IMPLICATION: Human-speed interaction detected — file content reviewed
  but read commands not explicitly captured in command log.

  [FINDING 4]  SSH KEY INJECTION PERSISTENCE ATTEMPT (T1098.004)
  ACTOR-873270 deployed 64 proxy IPs attempting SSH authorized_keys
  injection combined with chattr immutability to prevent removal.
  IMPLICATION: If successful on a production system, this attack establishes
  an unkillable backdoor. Priority remediation: audit .ssh/authorized_keys
  on all internet-facing Linux hosts and enforce chattr monitoring.

  STRATEGIC RECOMMENDATIONS───────────────────────────────────────────────────────────────────────
  1. Deploy HASSH-based detection on all SSH ingress — block the three
     campaign-flagged fingerprints (Phase VI IOC table).
  2. Enforce SSH key audit cadence on all internet-facing Linux hosts.
     ACTOR-873270 persistence method (T1098.004) is production-viable.
  3. Block Redtail staging infrastructure: 130.12.180.51 and all
     URLs from the Phase X IOC table at perimeter firewall.
  4. Consider honeypot-as-intelligence-collection: LP2 produced actionable
     IOCs in 22 days. Recommend operationalising this pipeline as a
     continuous threat feed into your SIEM.
  5. If VirusTotal API key is available — run Phase IV with key set to
     obtain live maliciousness scores for all ? payload hashes.

About the Author

Justin McCormick is a cybersecurity and threat intelligence practitioner with a background in military intelligence operations and applied analytics. His professional experience spans operational intelligence collection - combining analytic tradecraft with data-driven methodologies to better understand adversarial behavior and deliver these actionable insights to stakeholders.

This project reflects a deliberate effort to bridge intelligence analysis with modern machine learning workflows to develop proprietary tooling to assist with personal and professional research objectives. While contemporary large language models and AI-assisted development tools were leveraged to accelerate architectural ideation and prototyping, all modeling decisions, feature engineering strategies, visualizations, and analytical interpretations were independently validated as well as iteratively refined. The intent was not automation for its own sake, but disciplined augmentation — using modern tools to keep pace with the current threat landscape while preserving critical thinking and technical ownership.

Justin is particularly interested in the intersection of threat intelligence, cybersecurity operations across all domains (Enterprise, ICS/OT, Mobile), as well as emerging technologies and how these capabilities are wielded by adversaries - to include applied artificial intelligence. His long-term objective is to contribute meaningfully to the general understanding of the ever-evolving threat environment, design secure and scalable systems to bolster security efforts while mentoring the next generation of analysts and engineers through practical instruction and applied research.

This notebook represents both a technical exploration and a step toward that broader mission.

If you wondering about the project title - "Lost Piglet?"

See the Dana Carvey clip below, as this was stuck in my head throughout the project's ideation. The sketch may be old, but I can assure the reader: "it's a good one - Piglet gets Lost."
