Explore This Department of Justice Treasure Hunt On Use Of Surveillance Technologies

5/12/2023

 
Picture
​Credit to the Department of Justice for a voluminous response to our Freedom of Information Act (FOIA) request. Our request concerned the use of stingrays, or cell-site simulators, by that department and its agencies. Out of more than 1,000 pages in DOJ’s response, we’ve found a few gems. Perhaps you can find your own.
 
Review our digest of this document here, and the source document here.
 
The original FOIA request concerned DOJ policies on cell-site simulators, commonly known by the commercial brand name “stingrays.” These devices mimic cell towers to extract location and other highly personal information from your smartphone.
 
The DOJ FOIA response shows that the FBI in 2021 invested $16.1 million in these cell-site simulators (p. 209) in part to ensure they “are capable of operating against evolving wireless communications.” The bureau also asked for $13 million for “communications intercept resources.” This includes support for the Sensitive Investigations Unit’s work in El Salvador (p. 111).
 
On the policy side, we’ve reported that some federal agencies, such as the Bureau of Alcohol, Tobacco, Firearms and Explosives, maintain that stingrays are not GPS location identifiers for people with cellphones. This is technically true. Stingrays do not download location data or function as GPS locators. But this is too clever by half. Included in this release is an Obama-era statement by former Department of Justice official Sally Yates that undermines this federal claim by stating: “Law enforcement agents can use cell-site simulators to help locate cellular devices whose unique identifiers are known …” (p. 17)
 
This release gives an idea of how versatile stingrays have become. The U.S. Marshals Service (p. 977) reveals that it operates cell-site simulators and passive wireless collection sensors to specifically locate devices inside multi-dwelling buildings.
 
Other details sprinkled throughout this release concern other, more exotic forms of domestic surveillance.
 
For example, the U.S. Marshals Service Service has access to seven aircraft located around the country armed with “a unique combination of USMS ELSUR suite, high resolution video surveillance capability … proven to be the most successful law enforcement package” (p.881-883).
 
A surveillance software, “Dark HunTor,” exposes user data from Tor, the browser meant to make searches anonymous, as well as from dark web searches for information. (p. 105) In addition, the U.S. Marshals Service Service “has created the Open-Source Intelligence Unit (OSINT) to proactively review and research social media content. OSINT identifies threats and situations of concern that may be currently undetected through traditional investigative methods. Analyzing public discourse on social media, its spread (‘likes,’ comments, and shares), and the target audience, the USMS can effectively manage its resources appropriate to the identified threats.” (p. 931)
 
The DOJ release also includes details on biometric devices, from facial recognition software to other biometric identifiers, (p.353), as well as more than $10 million for “DNA Capability Expansion” (p.365).
 
Is that all? Feel free to look for yourself.
