Rayhunter: Uncovering Vital Clues: Our Current Findings and Insights

Open-Source Tool ‘Rayhunter’ Finds No Evidence of Cell-Site Simulator Use at US Protests

Washington D.C. – A recently released report indicates that the open-source tool Rayhunter has not detected the use of cell-site simulators – also known as IMSI catchers or Stingrays – at numerous protests across the United States. The findings, stemming from a year of community-led testing, suggest a potential shift in law enforcement surveillance tactics. the core focus of Rayhunter is detecting these devices, which mimic cell towers to identify and locate mobile phones.

Rayhunter, a Linux-based program compatible with various mobile hotspots, analyzes the communication “handshakes” between devices and cell towers. It flags anomalies indicative of a cell-site simulator. While thousands have installed the software and contributed to its growth, the project intentionally lacks telemetry to preserve user privacy.

Protest surveillance: A Changing Landscape

The project’s developers sought to determine if CSS were being deployed to monitor protests, notably in light of growing concerns about civil liberties. Despite testing at pro-Palestine demonstrations, events in Washington D.C. and Los Angeles, and gatherings associated with the ‘No Kings’ and ‘50501’ movements, Rayhunter has yielded no conclusive evidence of CSS activity within the US. Though,detections have been made in other,undisclosed locations.

Experts caution against interpreting this absence as definitive proof that CSS are not in use. Its possible that Rayhunter hasn’t been deployed to protests where CSS are active, or that the detection signatures need refinement to recognize evolving law enforcement techniques. Legal constraints, requiring warrants for CSS deployment in some jurisdictions, and the high cost – reportedly nearing one million dollars for equipment – may also play a role.

Alternative Surveillance Methods on the Rise

the report highlights that Police departments are increasingly turning to alternative surveillance methods that may be more accessible and cost-effective than CSS. These include:

Surveillance Technology	Description
License Plate Readers	Track vehicles arriving and departing protest locations.
Location Data Brokers	Monitor individuals’ movements via mobile advertising IDs.
Forensic Extraction Tools	Extract data from phones of arrested protestors.
geofence warrants	Obtain location data from internet companies for devices within a specific area.
Facial Recognition	Identify individuals using databases of facial images.
Tower Dumps	Acquire lists of all phones connected to a cell tower at a given time.

“Due to the lack of evidence regarding CSS, protesters may want to focus their concerns on these other, more readily available surveillance tactics,” stated a lead developer of the Rayhunter Project.

Rayhunter’s Successes and Future Development

Despite the lack of detections at US protests, Rayhunter has proven effective in identifying potential surveillance in other contexts. Important activity was detected at a cruise port in Turks and Caicos Islands, prompting further examination. Preliminary reports from Chicago and New York City indicated brief periods of “IMSI Sent without authentication” activity, a key indicator of CSS usage, although these were not linked to protests.

According to public records,the Immigration and Customs Enforcement agency (ICE) continues to employ CSS and recently renewed related contracts. Interestingly, a recent request by the FBI to utilize a CSS under the Foreign Intelligence Surveillance Act was denied in January.

The Rayhunter team is actively seeking data from international sources to expand the tool’s effectiveness and refine its detection capabilities.

Did You Know? Rayhunter detected every attack run by a commercial cell-site simulator during testing conducted by its collaborators at Cape.

Pro Tip: Protect your privacy at protests by considering a burner phone, utilizing secure messaging apps, and limiting location services on your devices.

Understanding Cell-Site Simulators

Cell-site simulators, often called “Stingrays,” are controversial surveillance devices used by law enforcement and intelligence agencies. Thay operate by mimicking legitimate cell towers, tricking nearby mobile phones into connecting to them instead. This allows the operators to identify devices, track their locations, and potentially intercept communications.

The use of CSS raises significant privacy concerns, as they can collect data on individuals who are not suspected of any wrongdoing. Widespread adoption of tools like Rayhunter aims to increase clarity and accountability regarding the deployment of these technologies.
