When Location Data Becomes a Security Threat

Click here to view/listen to our blogcast.

Most of us understand that smartphones can track our location. We use that capability for driving directions, weather forecasts, ride-sharing services, and finding a misplaced device. What is less obvious is how much location information can reveal, who may gain access to it, and how easily it can become a security threat.

A recent report described how Iran allegedly used weaknesses in mobile telecommunications networks and commercially available advertising data to help track U.S. military personnel and contractors in the Middle East. The attackers did not need to compromise every individual phone because the information generated by the devices and the networks around them was enough to locate their owners.

Military personnel are unusually valuable targets, but the underlying lesson applies to every organization: you do not always need to hack a phone to track the person carrying it.

Advertising Data Can Become Surveillance Data

Many mobile applications and websites collect information about devices, activity, interests, and location. Some of that collection serves a legitimate purpose. A navigation application needs your location to provide directions, and a company may track service vehicles to coordinate appointments. The danger arises when information collected for one purpose becomes available for another.

Citizen Lab recently examined a commercial surveillance system that reportedly used information from mobile applications and digital advertising to monitor devices and review their previous movements. The research demonstrates how data collected for advertising can potentially be repurposed for surveillance. The Federal Trade Commission has also acted against data brokers accused of improperly handling or selling sensitive location information, including data that could reveal visits to healthcare facilities, places of worship, and private homes.

A single location record may not appear meaningful. Combined across multiple applications and days, however, location data can create a detailed picture of someone’s routines, relationships, and responsibilities.

What Location Data Can Reveal About a Business

Most small organizations do not expect to be targeted by foreign intelligence services. That does not make their location data harmless. Tracking employee movements could help someone determine:

• Where an executive or business owner lives.
• When an office is normally empty.
• Which employee regularly visits the bank.
• Who has access to a warehouse, pharmacy, server room, or job site.
• When senior employees are traveling.
• Where company vehicles are parked overnight.
• Which clients, vendors, attorneys, or financial institutions employees visit.

That information could support burglary, stalking, competitive intelligence, social engineering, executive impersonation, or highly targeted phishing.

For example, a criminal who knows that an executive is traveling could impersonate that person and pressure an employee to make an urgent payment. A thief who learns when a facility is unattended may gain a physical advantage.

Location data does not have to reveal everything. It only needs to make an attack more believable.

Personal Devices Can Expose the Organization

A business may carefully manage its company-owned computers and phones while overlooking personal devices.

Employees carry personal smartphones into offices, medical facilities, client meetings, warehouses, and restricted areas. Those phones may contain applications that continuously collect location or advertising information.

The organization may not own the device, but the device can still reveal information about the organization. A firewall and antivirus software do not automatically prevent this kind of information leakage.

Reducing the Risk

Organizations should first determine where location data is being collected and whether that collection is necessary.

Employees should review application permissions and disable location access for applications that do not genuinely need it. “Allow only while using the app” is generally safer than permitting continuous background access.

Businesses should also consider:

• Managing company phones through a mobile device management platform.
• Restricting unapproved applications on company-owned devices.
• Disabling or limiting advertising identifiers.
• Reviewing fleet, vehicle, and employee-tracking services.
• Establishing rules for personal devices in sensitive locations.
• Avoiding social media posts that reveal real-time travel.
• Training employees to recognize targeted impersonation attempts.
• Removing unused applications and keeping devices updated.

No single setting will eliminate every form of tracking. The goal is to reduce unnecessary exposure and make useful information harder to collect.

How CDML Can Help

CDML can help organizations evaluate how smartphones, tablets, applications, wireless networks, and personal devices fit into their overall security program.

This may include implementing mobile device management, creating separate device profiles for company and personal use, enforcing security settings, restricting unapproved applications, and remotely removing business data from lost or stolen devices.

CDML can also help organizations deploy and manage business VPNs to protect network traffic when employees work remotely or use public Wi-Fi. A VPN does not block every type of location tracking, but it can reduce exposure by encrypting internet traffic and limiting what outside networks can see.

In addition, we can also review mobile device policies, application permissions, wireless access, employee awareness, and the use of personal devices for company business.

Location privacy is not merely a consumer concern. It belongs in the same conversation as cybersecurity, physical security, data protection, and employee safety.

Final Thoughts

Location information is more powerful than it appears. A history of movements can reveal routines, relationships, responsibilities, and vulnerabilities.

The lesson from military tracking is not that every organization faces the same threat. It is that information collected by ordinary phones, applications, advertisers, and mobile networks may be useful to people for whom it was never intended.

Businesses cannot prevent every device from generating location information. They can decide which applications they trust, how much information their systems collect, and whether employees understand what their devices may be revealing.

Contact CDML to review your mobile-device policies, application controls, and location-data exposure before this information becomes useful to the wrong person.

Stay safe. Stay informed. Stay compliant.
