Dallas, Texas — Geotab and Trimble announced new cybersecurity upgrades for their Electronic Logging Devices after a consultant warned that many ELDs trace back to designs from the early 1980s and could be exposed to remote attacks.

The trucking sector has transformed into a sprawling network of onboard computers, telematics, and IoT sensors. Since the FMCSA mandated ELD use in 2020, fleets have relied on these devices to log Hours of Service, track routes, and feed data to dispatch centers. That digital backbone now sits on hardware originally built for analog record‑keeping, creating a mismatch between modern threat vectors and decades‑old firmware.

Cybersecurity consultant Michael Hasse warned that retrofitting protection into an embedded system never designed for it drives costs sky‑high. He cited the early 1980s origin of many current ELD platforms as a root cause of vulnerability. Geotab’s senior security researcher Don Bailey responded that the company embeds authentication algorithms and continuous message validation into its GO devices, aiming to block firmware tampering and preserve CAN‑bus integrity. Trimble’s global business information security officer Conan Sandberg said the firm conducts white‑box testing on hardware and firmware, employs secure certificates, and rejects default manufacturer credentials that attackers often target. Both vendors stress ongoing firmware updates, endpoint detection, and threat‑intelligence feeds as essential defenses.

What This Means for Drivers

CDL‑A drivers and owner‑operators should verify that their ELD firmware is current before the next scheduled service. Fleet managers are urged to enforce strong password policies and restrict physical access to the device’s diagnostic port. A compromised ELD could, in theory, send false location data or even disable engine control, jeopardizing an OTR truck driver’s safety and the cargo’s security. Drivers who notice unexplained log entries or connectivity loss are advised to report the issue immediately to their carrier’s compliance team.

Industry Reaction

Carrier groups such as the American Trucking Associations have called for industry‑wide standards that require regular security audits of all telematics equipment. Independent owner‑operators echo the sentiment, demanding that vendors provide transparent update schedules and clear guidance on credential management. Meanwhile, some smaller fleets are exploring third‑party security services to supplement vendor protections, recognizing that a single vulnerable device can expose an entire route network.

Key Points

• ELDs originated in the early 1980s, leaving many units without built‑in cyber defenses.
• Geotab’s GO devices now validate message authenticity, integrity, and confidentiality to protect the CAN network.
• Trimble conducts white‑box testing, uses secure certificates, and eliminates default authentication settings.
• Drivers must keep firmware updated, use strong credentials, and report irregular device behavior to avoid potential remote hijacking.
