Hacking LTL Trucks: Outdated Code Puts Safety at Risk

Hacking LTL Trucks Made Easy with Outdated Code

Key Take-Aways:

  • Outdated code in trailer brake controllers makes LTL trucks vulnerable to hacking.
  • Hackers can gain control over the trailer’s brakes, posing a serious safety risk.
  • Trucking companies need to update their technology to ensure the security of their fleet.

In a shocking revelation, it has been discovered that hacking into LTL (Less Than Truckload) trucks is surprisingly easy due to the outdated code used in their trailer brake controllers. The code, which dates back to the 1980s, leaves these trucks vulnerable to malicious attacks. This poses a significant safety risk as hackers can gain control over the trailer’s brakes, potentially leading to disastrous consequences on the road.

The outdated code used in these controllers opens up a Pandora’s box of security vulnerabilities. With just a few lines of code, hackers can access the braking system and manipulate it remotely. This not only jeopardizes the safety of the truck’s cargo but also endangers the lives of drivers and other motorists on the road.

It is imperative that trucking companies take immediate action to address this alarming security flaw. Updating the technology in trailer brake controllers should be a top priority to ensure the safeguarding of their fleet. By incorporating modern and secure coding practices, these companies can significantly reduce the risk of hacking incidents and protect themselves from potential liabilities.


The trucking industry cannot afford to overlook the security threats posed by outdated code in trailer brake controllers. To protect their assets and the safety of everyone on the road, trucking companies must embrace the advances in technology and invest in robust and secure systems. Failure to do so could result in catastrophic consequences and irreparable damage to the industry’s reputation. It’s time for a tech-savvy revolution in the trucking world, leaving hackers in the dust and putting safety back on the road.
