Fines as a Security System

Tile has an interesting security solution to make its tracking tags harder to use for stalking:

The Anti-Theft Mode feature will make the devices invisible to Scan and Secure, the company’s in-app feature that lets you know if any nearby Tiles are following you. But to activate the new Anti-Theft Mode, the Tile owner will have to verify their real identity with a government-issued ID, submit a biometric scan that helps root out fake IDs, agree to let Tile share their information with law enforcement and agree to be subject to a $1 million penalty if convicted in a court of law of using Tile for criminal activity. So although it technically makes the device easier for stalkers to use Tiles silently, it makes the penalty of doing so high enough to (at least in theory) deter them from trying.

Interesting theory. But it won’t work against attackers who don’t have any money.

Hulls believes the approach is superior to Apple’s solution with AirTag, which emits a sound and notifies iPhone users that one of the trackers is following them.

My complaint about the technical solutions is that they only work for users of the system. Tile security requires an “in-app feature.” Apple’s AirTag “notifies iPhone users.” What we need is a common standard that is implemented on all smartphones, so that people who don’t use the trackers can be alerted if they are being surveilled by one of them.

Bulk Surveillance of Money Transfers

Just another obscure warrantless surveillance program.

US law enforcement can access details of money transfers without a warrant through an obscure surveillance program the Arizona attorney general’s office created in 2014. A database stored at a nonprofit, the Transaction Record Analysis Center (TRAC), provides full names and amounts for larger transfers (above $500) sent between the US, Mexico and 22 other regions through services like Western Union, MoneyGram and Viamericas. The program covers data for numerous Caribbean and Latin American countries in addition to Canada, China, France, Malaysia, Spain, Thailand, Ukraine and the US Virgin Islands. Some domestic transfers also enter the data set.

[…]

You need to be a member of law enforcement with an active government email account to use the database, which is available through a publicly visible web portal. Leber told The Journal that there haven’t been any known breaches or instances of law enforcement misuse. However, Wyden noted that the surveillance program included more states and countries than previously mentioned in briefings. There have also been subpoenas for bulk money transfer data from Homeland Security Investigations (which withdrew its request after Wyden’s inquiry), the DEA and the FBI.

How is it that Arizona can be in charge of this?

Wall Street Journal podcast—with transcript—on the program. I think the original reporting was from last March, but I missed it back then.

Identifying People Using Cell Phone Location Data

The two people who shut down four Washington power stations in December were arrested. This is the interesting part:

Investigators identified Greenwood and Crahan almost immediately after the attacks took place by using cell phone data that allegedly showed both men in the vicinity of all four substations, according to court documents.

Nowadays, it seems like an obvious thing to do—although the search is probably unconstitutional. But way back in 2012, the Canadian CSEC—that’s their NSA—did some top-secret work on this kind of thing. The document is part of the Snowden archive, and I wrote about it:

The second application suggested is to identify a particular person whom you know visited a particular geographical area on a series of dates/times. The example in the presentation is a kidnapper. He is based in a rural area, so he can’t risk making his ransom calls from that area. Instead, he drives to an urban area to make those calls. He either uses a burner phone or a pay phone, so he can’t be identified that way. But if you assume that he has some sort of smart phone in his pocket that identifies itself over the Internet, you might be able to find him in that dataset. That is, he might be the only ID that appears in that geographical location around the same time as the ransom calls and at no other times.

There’s a whole lot of surveillance you can do if you can follow everyone, everywhere, all the time. I don’t even think turning your cell phone off would help in this instance. How many people in the Washington area turned their phones off during exactly the times of the Washington power station attacks? Probably a small enough number to investigate them all.

Arresting IT Administrators

This is one way of ensuring that IT keeps up with patches:

Albanian prosecutors on Wednesday asked for the house arrest of five public employees they blame for not protecting the country from a cyberattack by alleged Iranian hackers.

Prosecutors said the five IT officials of the public administration department had failed to check the security of the system and update it with the most recent antivirus software.

The next step would be to arrest managers at software companies for not releasing patches fast enough. And maybe programmers for writing buggy code. I don’t know where this line of thinking ends.

Hacking Automobile Keyless Entry Systems

Suspected members of a European car-theft ring have been arrested:

The criminals targeted vehicles with keyless entry and start systems, exploiting the technology to get into the car and drive away.

As a result of a coordinated action carried out on 10 October in the three countries involved, 31 suspects were arrested. A total of 22 locations were searched, and over EUR 1 098 500 in criminal assets seized.

The criminals targeted keyless vehicles from two French car manufacturers. A fraudulent tool—marketed as an automotive diagnostic solution, was used to replace the original software of the vehicles, allowing the doors to be opened and the ignition to be started without the actual key fob.

Among those arrested feature the software developers, its resellers and the car thieves who used this tool to steal vehicles.

The article doesn’t say how the hacking tool got installed into cars. Were there crooked auto mechanics, dealers, or something else?

Using Foreign Nationals to Bypass US Surveillance Restrictions

Remember when the US and Australian police surreptitiously owned and operated the encrypted cell phone app ANOM? They arrested 800 people in 2021 based on that operation.

New documents received by Motherboard show that over 100 of those phones were shipped to users in the US, far more than previously believed.

What’s most interesting to me about this new information is how the US used the Australians to get around domestic spying laws:

For legal reasons, the FBI did not monitor outgoing messages from Anom devices determined to be inside the U.S. Instead, the Australian Federal Police (AFP) monitored them on behalf of the FBI, according to previously published court records. In those court records unsealed shortly before the announcement of the Anom operation, FBI Special Agent Nicholas Cheviron wrote that the FBI received Anom user data three times a week, which contained the messages of all of the users of Anom with some exceptions, including “the messages of approximately 15 Anom users in the U.S. sent to any other Anom device.”

[…]

Stewart Baker, partner at Steptoe & Johnson LLP, and Bryce Klehm, associate editor of Lawfare, previously wrote that “The ‘threat to life; standard echoes the provision of U.S. law that allows communications providers to share user data with law enforcement without legal process under 18 U.S.C. § 2702. Whether the AFP was relying on this provision of U.S. law or a more general moral imperative to take action to prevent imminent threats is not clear.” That section of law discusses the voluntary disclosure of customer communications or records.

When asked about the practice of Australian law enforcement monitoring devices inside the U.S. on behalf of the FBI, Senator Ron Wyden told Motherboard in a statement “Multiple intelligence community officials have confirmed to me, in writing, that intelligence agencies cannot ask foreign partners to conduct surveillance that the U.S. would be legally prohibited from doing itself. The FBI should follow this same standard. Allegations that the FBI outsourced warrantless surveillance of Americans to a foreign government raise troubling questions about the Justice Department’s oversight of these practices.”

I and others have long suspected that the NSA uses foreign nationals to get around restrictions that prevent it from spying on Americans. It is interesting to see the FBI using the same trick.

Stolen Bitcoins Returned

The US has returned $154 million in bitcoins stolen by a Sony employee.

However, on December 1, following an investigation in collaboration with Japanese law enforcement authorities, the FBI seized the 3879.16242937 BTC in Ishii’s wallet after obtaining the private key, which made it possible to transfer all the bitcoins to the FBI’s bitcoin wallet.

Law Enforcement Access to Chat Data and Metadata

A January 2021 FBI document outlines what types of data and metadata can be lawfully obtained by the FBI from messaging apps. Rolling Stone broke the story and it’s been written about elsewhere.

I don’t see a lot of surprises in the document. Lots of apps leak all sorts of metadata: iMessage and WhatsApp seem to be the worst. Signal protects the most metadata. End-to-end encrypted message content can be available if the user uploads it to an unencrypted backup server.

EDITED TO ADD (12/13): Here’s a more legible copy of the text.

How the FBI Gets Location Information

Vice has a detailed article about how the FBI gets data from cell phone providers like AT&T, T-Mobile, and Verizon, based on a leaked (I think) 2019 139-page presentation.

EDITED TO ADD (11/12): My mistake. It was not a leak:

Ryan Shapiro, executive director of nonprofit organization Property of the People, shared the document with Motherboard after obtaining it through a public record act request. Property of the People focuses on obtaining and publishing government records.
