What Does “Long Island Checks” Mean on Your Car Computer?

If you’ve ever glanced at your car’s infotainment screen or diagnostic tool and seen the phrase “Long Island Checks,” you might have shrugged it off as a glitch or a random error. But that phrase is anything but random. In fact, it’s a red flag—one that points to something far more serious than a software hiccup.

“Long Island Checks” is a term used by some automotive technicians and hackers to describe unauthorized diagnostic scans performed on a vehicle’s onboard computer system. These checks are typically done using an OBD-II (On-Board Diagnostics) scanner—a small device that plugs into a port usually located under the dashboard near the steering wheel. While legitimate mechanics use these tools to read error codes and diagnose engine problems, malicious actors can use them to extract sensitive data, manipulate vehicle settings, or even disable critical systems.

The name “Long Island Checks” likely originated from a specific group or individual based in the Long Island area who gained notoriety for performing these unauthorized scans on parked cars. Reports began surfacing in online car forums around 2020, where drivers described seeing strange messages on their dashboards or receiving alerts about unexpected system access. Some even noticed their cars behaving oddly—lights turning on by themselves, infotainment systems rebooting, or warning lights appearing and disappearing without explanation.

Why Is This Happening?

Modern vehicles are essentially computers on wheels. They contain dozens of electronic control units (ECUs) that manage everything from engine performance and braking to climate control and entertainment systems. These ECUs communicate over internal networks, and many are accessible via the OBD-II port. While this design makes diagnostics easier for mechanics, it also creates a potential entry point for hackers.

The rise of connected cars—vehicles with built-in Wi-Fi, Bluetooth, and cellular connectivity—has only increased the risk. Hackers can exploit vulnerabilities in these systems to gain remote access, sometimes without ever touching the car. But even without remote access, a simple physical connection to the OBD-II port can allow someone to download data, install malware, or alter settings.

In the case of “Long Island Checks,” the activity appears to be primarily data harvesting. Scanners may be collecting information such as:
– Vehicle identification number (VIN)
– Mileage and driving patterns
– GPS location history
– Connected device lists (phones, tablets)
– Software versions and system configurations

This data can be used for a variety of purposes, from resale on the dark web to targeted theft or insurance fraud. In some cases, hackers may even use the information to clone a vehicle’s digital identity or disable its immobilizer system.

How Do These Scans Happen?

You might be wondering: How can someone access my car’s computer without me knowing? The answer lies in the accessibility of the OBD-II port and the simplicity of the tools used.

The OBD-II Port: A Hidden Vulnerability

The OBD-II port has been standard in all cars sold in the U.S. since 1996. It’s designed to allow mechanics to plug in diagnostic tools and read error codes. But because it’s usually located in an easy-to-reach spot—often under the dashboard or near the center console—it’s also accessible to anyone with a few seconds and the right device.

All it takes is a $20 OBD-II scanner bought online, and a person can plug it in, run a quick scan, and walk away—leaving no visible trace. Some advanced scanners can even transmit data wirelessly to a smartphone or laptop, allowing the hacker to perform the scan from a distance.

Remote vs. Physical Access

While “Long Island Checks” are typically associated with physical access, the threat isn’t limited to someone sneaking up to your car. Remote hacking is also a growing concern.

Many modern vehicles come with telematics systems—like GM’s OnStar, Ford’s Sync, or Tesla’s over-the-air updates—that allow manufacturers to send software updates, track vehicle location, and even unlock doors remotely. While these features are convenient, they also create potential backdoors for hackers.

In 2015, security researchers famously demonstrated how they could remotely hack a Jeep Cherokee, taking control of its steering, brakes, and transmission. While such high-profile attacks are rare, they highlight the real risks posed by connected vehicles.

Even without full remote control, hackers can exploit weak passwords, unsecured Wi-Fi networks, or outdated software to gain access. For example, if your car’s infotainment system is connected to a public Wi-Fi network at a coffee shop, a hacker on the same network could potentially intercept data or install malware.

What Data Is at Risk?

When someone performs a “Long Island Check” on your car, they’re not just looking for engine trouble codes. They’re harvesting a wide range of data that can be used for malicious purposes.

Personal and Location Data

One of the most concerning aspects of these scans is the potential exposure of personal information. Many modern cars store data from paired smartphones, including call logs, text messages, and contact lists. If your phone is connected via Bluetooth or USB, a hacker could potentially access this information during a scan.

Even more alarming is the GPS data. Your car’s navigation system logs your frequent destinations—home, work, school, doctor’s office—creating a detailed map of your daily routine. This information can be used for stalking, burglary, or identity theft.

Vehicle Identification and System Details

Hackers can also extract your vehicle’s VIN, which is like a fingerprint for your car. With the VIN, they can look up your vehicle’s make, model, year, and even its original dealership. This information can be used to create fake registration documents or sell counterfeit parts.

Additionally, system details—such as software versions, ECU configurations, and security settings—can help hackers identify vulnerabilities. If a particular model of car has a known flaw, a hacker with this information can exploit it more easily.

Financial and Insurance Risks

In some cases, the data harvested from “Long Island Checks” can be used for financial gain. For example, hackers might use your driving patterns to file fraudulent insurance claims or sell your data to third parties.

There have also been reports of hackers using OBD-II scanners to reset mileage readings on used cars—a practice known as “odometer rollback.” This can significantly increase a car’s resale value, but it’s illegal and can mislead buyers about the vehicle’s true condition.

How to Detect Unauthorized Access

So how can you tell if your car has been scanned without your knowledge? While there’s no foolproof way to detect every intrusion, there are several signs to watch for.

Unexpected System Behavior

One of the most common indicators is unusual activity from your car’s electronics. This might include:
– The infotainment system rebooting or freezing
– Warning lights appearing and disappearing
– The climate control turning on or off by itself
– The radio changing stations or volume without input

These behaviors could suggest that someone has accessed your car’s computer system and altered settings or installed malware.

Unfamiliar Apps or Devices

Check your car’s connected devices list. If you see a phone, tablet, or other device you don’t recognize, it could mean someone has paired their device to your car’s Bluetooth or Wi-Fi.

Similarly, if your car’s infotainment system shows apps you didn’t install—especially diagnostic or hacking tools—it’s a strong sign of unauthorized access.

Diagnostic Logs and Alerts

Some advanced vehicles allow you to view diagnostic logs or system access history. If your car has this feature, check it regularly for unfamiliar entries. Look for timestamps when you weren’t using the car or locations where you didn’t park.

You can also use third-party OBD-II scanners or apps to monitor your car’s system activity. Some apps will alert you if someone plugs in a scanner or attempts to access your ECU.

Physical Signs

While not always present, physical signs can also indicate tampering. Check the OBD-II port for scratches, loose connections, or signs of forced entry. If the port cover is missing or damaged, it could mean someone has accessed it recently.

Also, inspect your car’s interior for unfamiliar items—USB drives, small devices, or sticky notes with codes. These could be left behind by someone who accessed your system.

How to Protect Your Car from Unauthorized Scans

Now that you know the risks, it’s time to take action. Protecting your car from “Long Island Checks” and other forms of automotive hacking requires a combination of physical security, software updates, and smart habits.

Secure the OBD-II Port

The simplest and most effective step is to physically secure your OBD-II port. You can do this by:
– Installing an OBD-II port lock or cover
– Using a steering wheel lock or gear shift lock to deter tampering
– Parking in well-lit, secure areas—especially overnight

OBD-II port locks are inexpensive (usually under $30) and easy to install. They prevent unauthorized devices from being plugged in, giving you peace of mind when your car is parked.

Disable Unused Connectivity Features

If you don’t use your car’s Wi-Fi or Bluetooth regularly, consider turning them off when not in use. This reduces the attack surface and makes it harder for hackers to gain remote access.

Also, avoid connecting your car to public Wi-Fi networks. These networks are often unsecured and can be exploited by hackers to intercept data or install malware.

Use Strong Passwords and Two-Factor Authentication

If your car has a connected app or online account—like MyChevrolet, MyFord Mobile, or Tesla’s app—make sure you’re using a strong, unique password. Avoid using the same password across multiple accounts.

Enable two-factor authentication (2FA) whenever possible. This adds an extra layer of security by requiring a code from your phone or email to log in.

Keep Software Updated

Manufacturers regularly release software updates to fix bugs and patch security vulnerabilities. Make sure your car’s systems are up to date by:
– Enabling automatic updates (if available)
– Visiting your dealership for scheduled maintenance
– Checking the manufacturer’s website for recall or update notices

Even if your car doesn’t have over-the-air updates, you can often download updates to a USB drive and install them manually.

Monitor Your Vehicle’s Activity

Stay vigilant by regularly checking your car’s systems and logs. Use diagnostic tools to scan for errors or unfamiliar activity. If you notice anything suspicious, report it to your dealership or a trusted mechanic.

You can also consider installing a vehicle security system with GPS tracking and remote monitoring. These systems can alert you if someone tries to access your car or if it’s moved without authorization.

What to Do If You Suspect Unauthorized Access

If you believe your car has been scanned or hacked, don’t panic—but act quickly.

Step 1: Disconnect and Secure

Immediately disconnect any paired devices and turn off Bluetooth and Wi-Fi. If possible, remove the OBD-II port cover or lock to prevent further access.

Step 2: Run a Diagnostic Scan

Use a trusted OBD-II scanner or visit a mechanic to run a full diagnostic scan. Look for error codes, unfamiliar software, or signs of tampering.

Step 3: Change Passwords

Change the passwords for your car’s connected apps and online accounts. Enable two-factor authentication if you haven’t already.

Step 4: Report the Incident

Contact your vehicle manufacturer and local law enforcement. Provide as much detail as possible, including timestamps, locations, and any suspicious behavior you noticed.

You can also report the incident to the National Highway Traffic Safety Administration (NHTSA) or the FBI’s Internet Crime Complaint Center (IC3). These agencies track automotive cybersecurity threats and may be able to help prevent future attacks.

Step 5: Consider a Security Audit

If you’re particularly concerned, consider hiring a cybersecurity expert to perform a full audit of your vehicle’s systems. They can identify vulnerabilities and recommend additional protections.

The Future of Automotive Cybersecurity

As cars become more connected and autonomous, the risk of cyberattacks will only grow. Manufacturers are investing heavily in cybersecurity, but consumers also have a role to play.

Industry Efforts
