Backdoor in TETRA Police Radios

Seems that there is a deliberate backdoor in the twenty-year-old TErrestrial Trunked RAdio (TETRA) standard used by police forces around the world.

The European Telecommunications Standards Institute (ETSI), an organization that standardizes technologies across the industry, first created TETRA in 1995. Since then, TETRA has been used in products, including radios, sold by Motorola, Airbus, and more. Crucially, TETRA is not open-source. Instead, it relies on what the researchers describe in their presentation slides as “secret, proprietary cryptography,” meaning it is typically difficult for outside experts to verify how secure the standard really is…

New York Using AI to Detect Subway Fare Evasion

The details are scant—the article is based on a “heavily redacted” contract—but the New York subway authority is using an “AI system” to detect people who don’t pay the subway fare.

Joana Flores, an MTA spokesperson, said the AI system doesn’t flag fare evaders to New York police, but she declined to comment on whether that policy could change. A police spokesperson declined to comment.

If we spent just one-tenth of the effort we spend prosecuting the poor on prosecuting the rich, it would be a very different world.

AI and Microdirectives

Imagine a future in which AIs automatically interpret—and enforce—laws.

All day and every day, you constantly receive highly personalized instructions for how to comply with the law, sent directly by your government and law enforcement. You’re told how to cross the street, how fast to drive on the way to work, and what you’re allowed to say or do online—if you’re in any situation that might have legal implications, you’re told exactly what to do, in real time.

Imagine that the computer system formulating these personal legal directives at mass scale is so complex that no one can explain how it reasons or works. But if you ignore a directive, the system will know, and it’ll be used as evidence in the prosecution that’s sure to follow…

Self-Driving Cars Are Surveillance Cameras on Wheels

Police are already using self-driving car footage as video evidence:

While security cameras are commonplace in American cities, self-driving cars represent a new level of access for law enforcement ­ and a new method for encroachment on privacy, advocates say. Crisscrossing the city on their routes, self-driving cars capture a wider swath of footage. And it’s easier for law enforcement to turn to one company with a large repository of videos and a dedicated response team than to reach out to all the businesses in a neighborhood with security systems…

Identifying the Idaho Killer

The New York Times has a long article on the investigative techniques used to identify the person who stabbed and killed four University of Idaho students.

Pay attention to the techniques:

The case has shown the degree to which law enforcement investigators have come to rely on the digital footprints that ordinary Americans leave in nearly every facet of their lives. Online shopping, car sales, carrying a cellphone, drives along city streets and amateur genealogy all played roles in an investigation that was solved, in the end, as much through technology as traditional sleuthing…

FBI (and Others) Shut Down Genesis Market

Genesis Market is shut down:

Active since 2018, Genesis Market’s slogan was, “Our store sells bots with logs, cookies, and their real fingerprints.” Customers could search for infected systems with a variety of options, including by Internet address or by specific domain names associated with stolen credentials.

But earlier today, multiple domains associated with Genesis had their homepages replaced with a seizure notice from the FBI, which said the domains were seized pursuant to a warrant issued by the U.S. District Court for the Eastern District of Wisconsin…
