EXECUTIVE SUMMARY
Lockard Security has identified and actively defended against a sophisticated multi-stage credential harvesting campaign targeting critical freight and logistics infrastructure since October 2025. The threat actor, designated Diesel Vortex, has successfully compromised 1,649 freight platform accounts across DAT, TIMOCOM, EFS, and related platforms, demonstrating advanced understanding of freight industry workflows and utilizing compromised credentials for physical cargo theft operations. This assessment provides tactical intelligence derived from active incident response engagements and ongoing threat hunting operations within freight-focused client environments.
Threat Actor Assessment
Diesel Vortex demonstrates operational characteristics consistent with financially motivated organized criminal groups with specialized freight industry expertise. Analysis of attack infrastructure, social engineering methodologies, and post-compromise behaviors indicates a mature threat organization with dedicated roles for reconnaissance, technical operations, and monetization activities.
Operational Sophistication
Unlike commodity phishing operations, Diesel Vortex employs real-time human oversight throughout attack execution. Our incident response telemetry shows attackers making tactical decisions during credential harvesting sessions, including:
- Dynamic session termination upon detection of security monitoring tools
- Real-time phishing page customization based on victim platform configurations
- Selective targeting based on administrative privilege assessment
- Post-compromise persistence establishment through legitimate RMM tool deployment
Industry-Specific Intelligence
Threat actor demonstrates deep operational knowledge of freight logistics workflows, evidenced by targeted harvesting of:
- DOT/MC certification data for carrier identity assumption
- RMIS access credentials enabling insurance verification fraud
- Electronic Logging Device (ELD) portal access for route intelligence
- Fuel card authentication factors supporting financial fraud operations
- Transportation Management System (TMS) integration tokens for persistent data access
Attack Chain Analysis
Five-Stage Multi-Vector Compromise Methodology
Stage 1: Initial Vector
Industry-specific spear phishing leveraging freight terminology and workflow knowledge
Stage 2: Staging Infrastructure
Minimal HTML iframe on legitimate .com domains with redirect chains
Stage 3: Evasion Layer
Nine-stage cloaking process across multiple domains to evade detection
Stage 4: Credential Harvest
Pixel-perfect platform clones with real-time operator control
Stage 5: Monetization
Cargo theft operations through load hijacking and double-brokering fraud

Data derived from active monitoring and incident response engagements
Target Platform Analysis
Primary Target Infrastructure
Critical freight platforms under active targeting by Diesel Vortex operators:
- DAT Truckstop — Load Board Platform
- TIMOCOM — European Logistics
- Teleroute — Transport Exchange
- Electronic Funds Source (EFS) — Fleet Payment
- Penske Logistics — Logistics Platform
Detection and Response Methodology
Lockard Security’s freight-focused SOC has developed specialized detection capabilities targeting Diesel Vortex tactics, techniques, and procedures (TTPs). Traditional email security and endpoint protection demonstrate insufficient coverage against this threat due to abuse of legitimate services and sophisticated social engineering.
Behavioral Detection Patterns
Our detection methodology focuses on behavioral indicators that resist traditional signature-based approaches:
- Homoglyph character analysis in email headers and message content
- Domain age correlation with freight industry terminology usage
- Redirect chain analysis identifying multi-stage cloaking patterns
- RMM tool deployment correlation with suspicious email activity
- Credential submission velocity analysis detecting automated harvesting tools
Post-Compromise Indicators
Endpoint telemetry from compromised environments reveals consistent post-exploitation behaviors:
- Browser credential extraction using legitimate password management tools
- Persistent remote access establishment through signed RMM applications
- Platform access pattern changes indicating account takeover
- Bulk data exfiltration targeting customer and route information
Indicators of Compromise
Infrastructure Patterns
- Domain Registration Patterns: Fresh .com domains with freight industry typosquatting
- Redirect Infrastructure: .top and .icu domains serving as cloaking intermediaries
- Email Service Abuse: Zoho SMTP and Zeptomail relay compromise
- Command & Control: Telegram webhook-based session management
Technical Indicators
- Homoglyph Substitution: Cyrillic character replacement in sender names
- User-Agent Strings: Consistent browser fingerprinting across phishing sessions
- TLS Certificate Patterns: Let’s Encrypt certificates on newly registered domains
- RMM Tool Deployment: ScreenConnect, SimpleHelp, PDQ Connect installations
