🔍 Why People Use RayHunter

1. To Detect Illegal or Unwanted Cellular Surveillance

The Problem:

Cell-site simulators,often referred to as Stingrays or IMSI catchers—can force your device to connect and quietly collect identifiers from every phone nearby. These tools have been used by agencies such as ICE and other law-enforcement groups, sometimes without public notice or proper oversight.

How RayHunter Helps:

RayHunter monitors LTE control-plane signaling and alerts you when a potential simulator is present. This gives you a chance to protect yourself, power down devices, use shielding (Faraday bags), or document the incident for legal or research purposes.

2. To Reveal Secret or Warrantless Surveillance Activity

The Problem:

Some agencies have historically deployed Stingrays without warrants and without disclosing their use, even to courts, attorneys, or the public. These devices are often used before raids or sweeps, and the communities affected typically have no way to detect them.

How RayHunter Helps:

RayHunter acts as an independent early-warning system. When suspicious activity is detected, users can document it or share the data with organizations like the Electronic Frontier Foundation (EFF). This contributes to transparency, community awareness, and legal accountability.

3. To Protect Against Criminals and Foreign Actors

The Problem:

It’s not only government agencies that use this technology. Criminal groups and foreign intelligence actors have deployed cellular simulators to track individuals, harvest identifiers, or initiate spoofed messages to trick victims into fraudulent transactions.

How RayHunter Helps:

RayHunter alerts you to the presence of any cell-site simulator, regardless of who controls it. This is vital for journalists, security professionals, business travelers, activists, or anyone who may be targeted for identity theft, tracking, or espionage.

4. To Hold Institutions Accountable

The Problem:

When surveillance technology is used without transparency or proper oversight, it disproportionately impacts vulnerable populations and erodes civil liberties. Communities often have no way to know when these tools are deployed around them.

How RayHunter Helps:

By making previously invisible surveillance visible, RayHunter gives ordinary people, researchers, and advocates the ability to monitor misuse, challenge improper deployment, and ensure that surveillance practices follow the law.

In Short

RayHunter is used because it provides visibility into a powerful, silent form of digital surveillance that can threaten privacy, free speech, and due process. It gives people a way to understand what is happening around them—and to protect themselves and their communities.
