Your Dashcam Could Be Spying on You

Your Dashcam Could Be Spying on You

A New Attack Surface on the Road

Dashcams are trusted as impartial witnesses — recording accidents, disputes, and unexpected moments on the road. But new research presented at Security Analyst Summit 2025 reveals a far more unsettling reality: many dashcams can be hijacked in seconds and silently weaponized for surveillance and future cyberattacks.

What looks like a safety device may actually be one of the weakest IoT links in your vehicle.

How Hackers Take Control

Cybersecurity researchers examined two dozen dashcam models across 15 brands, beginning with popular devices like Thinkware. Even dashcams without cellular connectivity were found to be vulnerable due to one shared feature: built-in Wi-Fi.

This Wi-Fi, designed for smartphone pairing, creates a broad attack surface.

Once attackers connect, they often find:

• Hardcoded default passwords

• Reused credentials across models

• Nearly identical hardware architectures

• Lightweight Linux systems running on ARM processors

In other words, classic IoT insecurity — now mounted on your windshield.

Authentication Bypasses in the Wild

Researchers demonstrated multiple ways attackers bypass dashcam protections:

Direct File Access

Many devices only check authentication at the login page — not when requesting files. Attackers can download videos without ever entering a password.

MAC Address Spoofing

By cloning the MAC address of the owner’s phone, attackers impersonate trusted devices and gain access instantly.

Replay Attacks

Legitimate Wi-Fi exchanges can be captured and reused later to re-enter the device.

Once inside, attackers can access:

• High-resolution video

• Audio recordings

• GPS location history

• Timestamps and metadata

Worm-Like Dashcam Infections

The most alarming discovery was self-propagating malware.

Researchers wrote code that runs directly on infected dashcams, allowing them to:

• Scan for nearby dashcams

• Attempt multiple passwords

• Exploit known vulnerabilities

• Spread automatically between vehicles traveling at similar speeds

In dense urban traffic, a single malicious payload could compromise up to 25% of dashcams nearby.

This turns everyday traffic into a moving surveillance mesh.

Weaponizing the Data

Once harvested, dashcam data becomes extraordinarily powerful:

• GPS metadata reconstructs full travel histories

• Road-sign text recognition identifies locations

• Audio transcription captures private conversations

• Behavioral analysis de-anonymizes drivers and passengers

Attackers can build detailed movement profiles — who you are, where you go, when you leave, and who rides with you.

This is surveillance at scale, powered by consumer hardware.

Why This Matters for SMBs, Schools, and Healthcare

Dashcams are increasingly used in:

• Delivery fleets

• Service vehicles

• School transportation

• Healthcare transport

• Rideshare and contractor operations

A compromised dashcam can leak:

• Client locations

• Daily routes

• Facility entrances

• Employee conversations

• Operational patterns

This is no longer a personal privacy issue — it’s an organizational risk.

How to Reduce Your Risk

Drivers and fleet managers should act immediately:

• Disable dashcam Wi-Fi when not in use

• Change default passwords immediately

• Apply firmware updates regularly

• Avoid unknown companion apps

• Treat dashcams like any other IoT device

If it connects to Wi-Fi, it needs security hygiene.

The Provocative Takeaway

Your dashcam doesn’t just watch the road.

If unsecured, it can watch you — and report everything.

As vehicles become rolling networks, cybersecurity must extend beyond laptops and phones…

all the way to the windshield.

70% of all cyber attacks target small businesses, I can help protect yours.
