Digital Highway Robbery: Inside the Ruthless World of Modern Cargo Hackers

It started with a simple email, but ended with a sophisticated heist. In the digital age, the classic image of masked robbers targeting trucks on winding highways has given way to a new breed of criminal - one who operates from behind a keyboard, targeting the very heart of the global supply chain. Recent research by Proofpoint has pulled back the curtain on these invisible marauders, revealing a web of organized cybercrime that’s quietly bleeding the logistics industry dry.

Fast Facts

• Cargo theft losses in North America hit $6.6 billion in 2025 - much of it enabled by cyberattacks.
• Hackers are infiltrating load board platforms to target dozens or even hundreds of small trucking carriers at once.
• Remote access tools are deployed in layers, with attackers using advanced certificate-signing tactics to evade detection.
• Cybercriminals go beyond stealing cargo - scanning for financial accounts, cryptocurrency wallets, and payment platforms.
• At least a dozen criminal groups are actively targeting the transportation sector in North America and Europe.

Proofpoint’s researchers spent a month tracking the movements of these cybercriminals, who have mastered the art of digital infiltration. Their targets? Not just the corporate giants, but the thousands of small operators - many with fewer than ten trucks - who lack the resources to defend themselves.

It begins when hackers compromise “load boards” - online marketplaces where freight brokers and shippers connect to arrange cargo movement. A single malicious email to a carrier can unleash a cascade of remote access tools. In one observed attack, six separate tools were installed, including four instances of ScreenConnect. This redundancy ensures continued access even if some tools are discovered and removed.

But the real innovation comes from how these hackers dodge security measures. Proofpoint’s team discovered the use of a so-called “signing-as-a-service” script: a tool that automatically queries an external certificate signing service, digitally “blessing” malware so that Windows trusts it. This makes the attack nearly invisible to defenders, even as it quietly replaces and re-signs each malicious component.

The hackers’ ambitions don’t end with cargo theft. Once inside, they search for every possible financial foothold, scanning devices for cryptocurrency wallets, PayPal credentials, access to financial institutions, money transfer services, and even fuel card providers. Their knowledge of the transportation sector is chillingly precise, enabling them to monetize every compromised workstation to the fullest.

The scale of the threat is daunting. By targeting the digital infrastructure that underpins the industry, hackers can simultaneously compromise hundreds of carriers. The combination of technical sophistication and ruthless efficiency is transforming cargo theft from a physical crime into a high-tech epidemic - one that spans continents and costs billions.

As the logistics industry races to catch up, one thing is clear: the digital highway is every bit as dangerous as the open road. For the world’s small carriers, the next attack may not come with a gun, but with a mouse click.

• Load Board: A load board is an online marketplace where shippers post freight loads and carriers find available jobs, but users should beware of potential scams.
• Remote Access Tool (RAT): A Remote Access Tool (RAT) is software that allows someone to control a computer remotely, used for both legitimate support and malicious cyberattacks.
• Certificate Signing: Certificate signing verifies digital certificates’ authenticity and integrity, ensuring secure, trusted communications and data exchanges in cybersecurity environments.
• Payload: A payload is the harmful part of a cyberattack, like a virus or spyware, delivered through malicious emails or files when a victim interacts with them.
• PowerShell Script: A PowerShell script is an automated set of commands for Windows computers, used to manage or change systems - sometimes exploited by attackers.
